Abstract
This study was aimed at isolating Pseudomonas aeruginosa from the soil to produce biosurfactant for degradation of herbicide. The soil sample was collected from oil polluted site in mechanic workshop, Minna, Niger State, Nigeria and transferred to the microbiology laboratory of the University in a sterile polyethylene bag. Pseudomonas aeruginosa was isolated from the soil and identified using microbiological and biochemical assays. The isolate was screened for biosurfactant production using haemolytic assay, drop collapse, oil spreading and emulsification test. Biosurfactant production was carried out using mineral salt medium for ten days. The ability of the biosurfactant produced by P. aeruginosa in degrading herbicide was tested on five concentrations of herbicide (5%, 10%, 30%, 50%, 70%) and the results showed biodegradation percentages as 56.4%, 53.1%, 32.6%, 29.8% and 26.2% respectively revealing that degradation was higher at lower concentrations. This suggests that herbicide could be biodegraded especially at low concentrations using biosurfactant produced by Pseudomonas aeruginosa.
Contribution/ Originality
The paper's primary contribution is finding that biosurfactant could be produced from bacteria (Pseudomonas aeruginosa) and this could be used for degradation of herbicide that has remained an environmental problem.

Abstract
The impact of military spending on domestic output is contentious and therefore requires further analysis on a country by country basis to determine its level of significance. Nigeria’s military contributions to the Economic Community of West African States (ECOWAS) sub-region and the recent rise of various insurgencies, particularly, Jam??at Ahl al-Sunna lil-Da?awah wa al-Jih?d’ (Boko Haram) – arguably the most fatal insurgent group – has increased Nigeria’s military expenditure. This study investigates the impact of this increase in military spending on the economic well-being (measured by GDP per capita) of Nigerians using the Autoregressive Distributed Lag (ARDL) bounds testing approach to co-integration for the period from 1988 to 2017. The results suggest that there is a positive relationship between military spending and economic well-being in Nigeria. However, the impact on citizens’ wellbeing is not instantaneous as the variable is only significant after the current year spending; which does not last longer than a year. The study therefore recommends that defense spending be strategic, and that all earmarked funds for defense be deployed appropriately so that increases in wellbeing can be more long-term as opposed to lasting for only one year.
Contribution/ Originality
This study contributes to existing literature on military spending and growth. This study uses an adapted model.

Abstract
Despite tremendous progress in drug development and treatment, infectious diseases caused by bacteria are still a major threat to human and animal health mainly due to drug resistances. These the ever-increasing threats demand a global effort to search for novel solutions. Different parts of plants and bee’s honey have been used, separately or in combination, as a source of therapeutic agents in traditional medicine since ancient time due to bioactive compounds they contain. Therefore the objective of this study is to determine the antibacterial activity of crude extract of Embelia schimperi leaves and combined with bee’s honey (Apis florae) against some standard and clinical pathogenic bacteria. The In-vitro antibacterial activity of the extracts was tested at different concentrations by using agar well diffusion method and measuring zone of inhibition. The data was analyzed by ANOVA. Both the clinical and standard bacteria showed sensitivity to E. schimperi with inhibition zones ranging from 7.17 ± 0.29 to 28.96 ± 0.25. The ethanol extract of E. schimperi leaves and ethanol extract blended with honey have showed significant inhibition against the tested organisms than the chloroform extract and chloroform extract blended with honey respectively. The inhibition zone was lower against S. aureus during both the Chloroform leave extract and the chloroform blended with honey. The highest inhibition zone was observed against E. coli with the ethanol leave extract and against K. pneumonia with the ethanol mixed with honey. Therefore, the E. schimperi leaves extract and synergy with honey has witnessed broad spectrum antibacterial activity.
Contribution/ Originality
This study contributes to the existing literature of the antibacterial effects of leaf extracts of E. schimperi. It is the only study that investigated the synergetic effects of leaves of E. schimperi with honey. Therefore, the synergy of the leaves with honey has shown promising antimicrobial effect.

Journal: Journal of Social Economics Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper aims to investigate the impact of social and psychological barriers on the negative intention of female students to be an entrepreneur and to analyze the mediating role of psychological barriers between social barriers and negative entrepreneurial intention. Total of 791 female students were surveyed from Bangladesh through an on-line questionnaire. Four hypotheses have been developed and tested on the total sample. Structural equation modeling (SEM) is used to measure the validity of the data and the relationship among the variables. The study endorsed that social barriers have a significant negative association with the negative intention toward entrepreneurship that indicates social barriers do not significantly reduce the entrepreneurial intention. Psychological barriers as mediating variable have a significant and positive relationship with social barriers and those barriers also have a significant positive effect on negative intention toward entrepreneurship. Psychological barriers partially mediate the relationship between social barriers and the intention toward entrepreneurship. Thus, social barriers through psychological barriers significantly influence the entrepreneurial intention and reduce the inclination of female students toward entrepreneurship.
Contribution/ Originality
This study originates unique findings that social barriers do not directly contribute to reducing the entrepreneurial intention, but psychological barriers significantly reduce the intention of the female students toward entrepreneurship. Besides, psychological barriers play a mediating role between social barriers and entrepreneurial intention.

Abstract
While many African countries raise 15% or more in tax revenue, some countries like Ethiopia still do not raise the necessary amount of resources to allow for the sound functioning of domestic institutions and basic service delivery. Therefore, this study investigated the perceived effect of selected factors on tax revenue mobilization in Ethiopia. Data is collected through a structured questionnaire and analyzed using univariate statistics namely one sample T-test and other descriptive statistics including proportions and means. The findings revealed that the political instability of the country has negatively affected the normal business operation of firms; reduced investments due to lower confidence of investors and negatively affected the taxable income of business firms. The results, however, revealed that closeness to general elections doesn’t affect normal business operation of firms. The findings also revealed that there is high corruption by tax officials in our region; taxpayer awareness creation to report any corruptive practices is also weak; measures by the tax authority to improve the accountability of tax officials are also limited or none and those corruptive practices have negatively affected the amount of tax the revenue office could mobilize. Finally, the study uncovered that the present tax audit practice does not reduce tax evasion and other irregularities in our region and that the awareness of taxpayers of tax audit per se doesn’t make the tax payers render a satisfactory tax return. We also found that the tax administrative structure lacks autonomy and there is the inadequacy of skilled and competent employees in the tax administration.
Contribution/ Originality
This study contributes to the existing literature by investigating the relationship among tax revenue mobilization of the recent political instability, the level of corruption, the present tax audit practice, the level of autonomy of the tax authority and competence of revenue collectors in Ethiopia, specifically, in Amhara region.

Journal: Journal of Social Economics Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In Ethiopia, MSEs have become the favorite of policy makers as they are believed to play a critical role in addressing both poverty reduction and economic growth goals. Over the years, while some MSEs have grown extremely large and profitable, many others have failed or have not been as successful as they might have been. This study seeks to identify the factors that hamper the success of Micro and Small Enterprises in Amhara region of Ethiopia since studies aimed at assessing the same are virtually missing. This study employed a quantitative research approach using a descriptive survey design. The data was drawn from a survey of 316 MSEs in Amhara region, Ethiopia. Statistical models including One Way Analysis of Variance (ANOVA) and T-test are used to analyze the data apart from other descriptive statistics such as percentages and mean. The study has revealed that working premises, marketing and financial factors are the three most serious factors that hamper the success of MSEs. We suggest that since the real challenges of MSEs change over time, the challenges of MSEs must be studied at some periodic interval to identify the real challenges of MSEs of the time and take appropriate action timely.
Contribution/ Originality
The study contributes to the existing literature by revealing the critical factors that hamper the success of MSEs and may help the local government to devise ways to support these enterprises in efforts to eradicate poverty and achieve sustainable development by 2030.

Abstract
The development in the eco-friendly and cost-effective green synthesis of metal and semiconductor nanoparticles utilizing several natural resources like microorganisms, plant, flower and fruit extracts is an emerging area of nanotechnology. In recent years, the development of efficient green chemistry methods for synthesis of metal nanoparticles has become a major focus of researchers. One of the most considered methods is production of metal nanoparticles using organisms. Among these organisms plants seem to be the best candidates and they are suitable for large-scale biosynthesis of nanoparticles. Nanoparticles produced by plants are more stable and the rate of synthesis is faster than in the case of microorganisms. Moreover, the nanoparticles are more various in shape and size in comparison with those produced by other organisms. The advantages of using plant and plant-derived materials for biosynthesis of metal nanoparticles have interested researchers to investigate mechanisms of metal ions uptake and bioreduction by plants, and to understand the possible mechanism of metal nanoparticle formation in plants. In this review, most of the plants used in metal nanoparticle synthesis are shown. Researchers have focused their attention on understanding the biological mechanisms and enzymatic processes of nanoparticle biosynthesis as well as detection and characterization of biomolecules involved in the synthesis of metallic nanoparticles. Many biomolecules in plants such as proteins/enzymes, amino acids, polysaccharides, alkaloids, alcoholic compounds, and vitamins could be involved in bioreduction, formation and stabilization of metal nanoparticles. Genetic modification of plants with improved metal accumulation capacities is the future approach to increase the productivity of these organisms in nanoparticle synthesis.
Contribution/ Originality
This study contributes to develop the efficient green chemistry methods which have investigated synthesis of metal nanoparticles

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This study examines the relationship between financial development, economic growth, and inflation five developing Southeast Asian countries between 1997 and 2016 using a vector autoregressive model. The results revealed that: inflation positively affected money supply and stock market capitalization, but GDP per capita growth rate negatively; GDP per capita growth rate was positively correlated with domestic credit to the private sector; money supply positively affected stock market capitalization and inflation; domestic credit to the private sector exerted a positive influence on GDP per capita growth rate, but negative on inflation; and stock market capitalization was negatively related to inflation. Further, a directional relationship runs from GDP per capita to inflation, from inflation to money supply, and from inflation to domestic credit to the private sector. Policies are recommended to promote economic growth, reduce inflation, and achieve sustainable development in Southeast Asia. First, inflation should be carefully controlled as it causes a decline in the GDP per capita growth rate. Second, GDP per capita growth rate should be promoted owing to its positively effect on domestic credit to the private sector, which has been an important catalyst for economic growth in Southeast Asia over recent decades. Finally, domestic credit to the private sector and stock market capitalization should be fostered because of their contribution to reducing inflation and increasing the GDP per capita growth rate.
Contribution/ Originality
This study contributes to the existing literature by clarifying the causal relationship between financial development, economic growth, and inflation in five developing Southeast Asian countries between 1997 and 2016, using a vector autoregressive model.

Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The study investigated the prevailing factors over age reporting and other socio-demographic information during the Nigerian population census. The study was carried out in south eastern Nigeria, using the cross sectional survey method. The sample size was 597 respondents, males and females aged 26 and older. The analysis examined the latent factors that affected the reporting of age and other socio-demographic status of the citizens using descriptive statistics and logistic regression. From the data, the study demonstrated that age reporting can be predicted by educational level (?= .075, t= 1.965, P<.05), the means of information about the population census (?= .126, t= 3.272, P<.05) and the citizens’ understanding of the census as a means of knowing their needs by the government (?= .343, t= 8.943, P<.05); similarly, reporting of occupational status can be predicted by educational levels (?= .130, t= 3.263, P<.05) and the citizens’ understanding of census as a means of knowing their needs by the government (?= . 263, t= 6.592, P<.05), etc. The study revealed the loopholes that affected the 2015MDG target and set a pace to achieve the post-2015 SDGs. The study has raised a concern for the empirical evaluation of census participation and socio-demographic status reporting.
Contribution/ Originality
This study contributes to the existing literature on population studies. It uses new estimation methodology and originates age-reporting studies. It is one of very few studies which have investigated age-reporting. The paper contributes the first logical analysis of age-reporting. Its primary contribution is finding that census data are not absolutely dependable. This study documents age reporting lapses.

Abstract
The term corruption is a multidimensional phenomenon that encompasses abuse of power, misappropriation of public resources, fraud, bribes, collusion, and other rent-seeking activities undertaken for private gain, monetary and non-monetary. Applying a logit model to a survey of 100 individuals and 50 small-to-medium-sized private firms, this study investigates the causes, dissemination channels, and consequences of corruption in Zimbabwe for the period 1998 to 2018. Opportunity perceptions, political instability, weak public institutions, excessive market regulations, red tape, cultural tolerance, competition, poverty, risk capital, business uncertainties, high taxation rates, the existence of a shadow economy, and the level of education were found to be the main causes of corruption. The channels of its dissemination are primarily the monetary and fiscal policies that implement macro-controls. This study therefore recommends the adoption of policies that reduce excessive market regulations for private exchanges, ensure the rule of law, restore macroeconomic stability, enhance regulatory quality and efficiency, develop robust and transparent public institutions, and minimize the discretionary powers of bureaucrats and politicians. Furthermore, to improve accountability, Zimbabwe should implement policies that ensure the forfeiture and repatriation of the proceeds of corruption, early detection of corruption, and prosecution of perpetrators, without fear or favor. Finally, severe penalties should be imposed on all cases of corruption, regardless of how petty, as preventive and deterrent measures.
Contribution/ Originality
This study contributes to the existing literature on the causes and consequences of corruption in Zimbabwe. Unlike similar studies that rely on cross sectional surveys, this study pioneers the application of binary choice models, in the form of the logit regression model, to examine the causes and dissemination channels of corruption.

Abstract
Adoption and use of e-commerce technologies continue to rise because they provide access to global markets, offer a competitive advantage and increase the effectiveness of businesses. Safety and trust are important factors that affect users' intentions and use of e-commerce technologies. Considering the upsurge of cyber-crime activities and the paucity of research in this domain particularly in developing countries, this paper investigated how cyber-crime perceptions affect users' intention to conduct business via e-commerce technologies. Using a survey approach, an online questionnaire was distributed and data from 476 participants was rigorously analyzed using Partial Least Square Structural Equation Modelling. The paper extends the theory of reasoned action with relevant constructs; trust and cyber-crime perceptions. The relationships between the constructs were based on deductive reasoning from prior studies. The hypothesized model explained 33.1% of the variance in Attitude Towards Behavior and 41.5% of Consumers Intention to Purchase. The results indicate that trust in internet medium, attitude towards behavior, subjective norm and cyber-crime perceptions are significant predictors of intention to purchase using e-commerce. There was, however, no significant relationships between Trust of Ecommerce Sellers and Cyber Crime Perceptions as well as Trust of Ecommerce Sellers and Consumers Purchase Intention. The findings elucidate businesses and stakeholders on the impacts of trust and cyber-crime perceptions on users' purchase intentions. It also inspires e-commerce technology developers to incorporate security features that reduce the vulnerability of these systems. Finally, the findings for this study are limited to respondents from Ghana hence future analysis could explore other countries.
Contribution/ Originality
This study is one of the very few studies which have investigated the effects of cybercrime on e-commerce technologies from the perspective of a developing country. In fact, the first study in Ghana, which attempts to examine consumers’ perception of cybercrime on their purchase intentions using electronic commerce technologies.

Abstract
This study investigated the transesterification of Rubber seeds (Hevea brasiliensis), Avocado Pear seeds (Gratissima persea), and Nipa Palm Kennel seeds (Nypa frutican) locally sourced from Nigeria as an adsorbate for the esterification reaction of oleic acid with methanol. Reaction was catalysed by potassium hydroxide (KOH) to form methoxide oleate (biodiesel) adsorption from aqueous solution in batch model for the production of biodiesel. The results obtained showed that rubber seeds oil (RSO), Avocado pear seeds oil (APO) and Nipa palm kernel seed oil (NPKO) oil gave maximum biodiesel yields at 0.9 % w/v, 0.1 % w/v and 0.1 % w/v catalyst concentration respectively. Their biodiesel yields were 88.0 %, 92.0 % and 96.7% respectively. They recovered biodiesel were characterized as an alternative fuel via specific gravity, viscosity, acid value, flash point and cloud point. The results obtained showed that the specific gravity for RSO (0.886 kg/m3), APO (0.876 kg/m3) and NPKO (0.850 kg/m3) were fairly significant at temperature of 25 oC to other conventional petroleum diesel ASTM D 975, standard biodiesel ASTM D975, and standard biodiesel ASTM 6751 and EN14214.
Contribution/ Originality
This study is one of very few studies which have investigated on Nigeria local plants capable of producing biodiesel via catalysed trans-esterification reaction.

Abstract
Introduction of genetic engineering in agriculture is a recent idea of native scientists. Scientists from Bangladesh Agriculture Research Institute (BARI) are working on developing an FSB resistant brinjal variety namely Bt-brinjal in collaboration with Cornel University, USA. In addition, this study was attempted to find out the potential economic benefit and producers’ willingness to adopt Bt-brinjal. A total of 80 respondents were randomly selected from Gazipur and Jamalpur districts. Descriptive statistics and Logistic regression analysis were used to analyze data. Yield gain and reduction in insecticide use data give the result as Bt-brinjal will increase yield by 65.76 percent and 44.87 percent and reduce pesticide cost by 71 percent and 70.36 percent compared to local OPV and Hybrid brinjal respectively. 98 percent of farmers will produce Bt-brinjal if they reduce insecticide use but 65 percent will not produce it if there are any health-related issues. Mass advertisement is also a significant factor of adoption (63.75 percent). It was found that the marketing channel for Bt and non-Bt brinjal is same. For this producers’ adoption of Bt-brinjal is related to the potential benefit and harmlessness of the technology. Results also showed that adoption is significantly influenced by education, own land size, no. of spray per season, season of growing brinjal (p<.01) and household size, type of growing brinjal (p<.05) respectively. Though voice against GM crops was also very loud but the Bangladesh government is very much eager to introduce this technology to the market and give the benefits to its consumers.
Contribution/ Originality
This study is one of the very few studies which have investigated potential economic benefit and producer willingness to adopt of Bt-brinjal in Bangladesh. This study was an ex-ante analysis related to Bt-brinjal adoption in Bangladesh. Hence; this is an original contribution in this field.

Abstract
The present study aims to investigate the impact of social media on the value system (especially citizenship, time respect, others' privacy respect, family communication, and communication values) among the students of the College of Education, Princess Nourah bint Abdulrahman University. It utilized the descriptive approach and applied a 40-item questionnaire covering (5) domains to a randomly selected sample of (142) students. Results revealed a positive impact of social media on citizenship and communication values, a moderately negative impact on time respect, and a poor impact on others' privacy respect and on family communication. There were no statistically significant differences in the impact of social media on the value system due to (specialization, family's economic status, time spent on social media, and preferred social media). The study results call for benefiting from the positive impacts of social media and sensitizing students to the negative ones, especially time respect and its optimal use, as well as conducting qualitative studies on the reasons for spending too much time on social media.
Contribution/ Originality
This study contributes to the existing literature by identifying the impact of social media on the value system among the students of the College of Education, Princess Nourah bint Abdulrahman University, Saudi Arabia. It explores the impact of social media on student values e.g. citizenship, time respect, others' privacy respect, social communication, family communication, and communication values.

Abstract
Quality of the instructional process is at stake when taught by out-of-field teachers. The current study identified the problems met by such teachers who teach across their specialization in the teaching of social studies. These Out-of-field social studies teachers encounter several issues in the preparation and administration of their lessons. This study first identified this specialization-workload mismatch and investigated what coping mechanisms can be introduced for the survival of these teachers in and out-of-field-teaching environment. The study employed a qualitative phenomenological research methodology and conducted an in-depth interview using open-ended questions, in order to generate the eidetic insights of the issues. Ethical considerations were administered to protect the confidentiality of the research participants. The data collected were translated and analyzed, resulting in the unveiling of themes and concepts from the narratives of the research participants. In the light of these findings, a Heideggerian interpretive analysis catapulted the creation of a Culture-based BAYLE Teaching Model (BTM) for that could be a solution to the out-of-field teaching individuals. The study recommends the introduction of BTM in all schools facing out-of-field issues.
Contribution/ Originality
This study contributes a pioneering mechanism in responding to the problem of out-of-field social studies teaching in the workplace using Heidggerian interpretivism. This study recommends crafting of a culture-based model of innovative instructional delivery known as the Bayle Teaching Model–a legacy of the Philippines to cultural global education.

Abstract
In order to learn more about the antecedents and consequences of tourist decision making in the medical tourism industry, this study reveals how risk perception influences the tourist decision making of medical tourism development. Then, we test the hypothesis by collecting survey data of 226 from respondents of different hospitals at Dhaka in Bangladesh who came for medical treatment there. Moreover, we hypothesize that tourist experience, tourist attitude, and media influence increases tourist decision making with the mediating effect of risk perception. The findings confirm a positive significant relationship between tourist experience and media influence on risk perception. A positive direct relationship between media influence and tourist decision making was also found. Then, we examine how risk perception mediates this relationship with tourist decision making which is found positive. However, this study didn’t find any significant relationship between tourist attitude and risk perception, in contrast with the earlier findings. Our results extend previous research by not only highlighting the importance of medical tourism in shaping the host destination’s strategic behavior but also indicating how each dimension of medical tourism influences on enhancing the tourist decision.
Contribution/ Originality
This study is one of the very few studies which have investigated the relationship between tourist experience, tourist attitude and medical influence on risk perception towards tourist decision making for the sustainable development of medical tourism through empirical analysis and analyses whether tourist become satisfied through risk perception.

Abstract
Despite the proliferation of research on cash holdings, the effects of external factors on corporate cash policy are little known. There are only a handful of studies have examined the relationship between issues related to institutional factors and cash holdings to date. Many studies have examined the effects of internal, as opposed to external factors on firms’ cash holdings behaviours. External factors, such as institutional environment have mostly been neglected in the extant literature, despite the fact that institutional factors have a direct effect on firms’ behaviours and strategic choices. This paper inspects the relationships between country governance and corporate cash holdings. This paper presents a cross-country study using 1274 firm-year observations from 2001 to 2013 from public listed hospitality firms in ASEAN-5 to test the impact of corporate governance on cash holdings. The relationship between external governance mechanism and cash holdings behaviour of firms at country-level are studied. The results show positive and significant relationship between the country-level control of corruption, regulatory quality, the rule of law, and corporate liquidity. However, there is no significant relationship between country-level political stability, voice and accountability and corporate liquidity. Further investigation was carried out to test the effect of tourism crisis and corporate liquidity. The results shall benefit various parties including the legislators and policy makers. Not only it serves as a strategic deterrence, but also helps firms to gauge opportunities.
Contribution/ Originality
This study contributes to a growing body of cash literature by demonstrating how corporate cash holdings are influenced by country governance. Although enhancing governance mechanisms at the firm level is important in alleviating agency problems within the firm, improving the governance mechanism at the country-level first can be equally important.

Abstract
The study was carried out on the Evaluation of repellency of plant-derived insecticide against brinjal and pepper pest populations. Two crops brinjal and pepper were sown separately and sprayed with Neem Seed Extract against whitefly, jassid, aphid, borer and predators. The population was significantly higher 3.70 whitefly/ leaf on brinjal variety F1-advanta-305 as compared to PPL 3.10/ leaf and Black long 3.31/ leaf respectively recorded on 20th January. Similarly, the population was relatively higher was 2.86, 2.72 and 2.44 jassid/ leaf on F1-advanta-305, PPL and Black long varieties respectively on 25th January. Aphid population was slightly higher 2.79, 2.39 and 2.26/ leaf on Black long, F1-advanta-305 and PPL varieties respectively. Likewise, the predator population was higher 2.26, 1.99 and 1.94/ plant on brinjal varieties of F1-advanta-305, Black long and PLL respectively on 4th February. The population was significantly higher 6.33, 5.28 and 4.8 whiteflies/ leaf on Talhari, Moro chilly and Mirch shehzadi respectively on pepper varieties on 25th January. Similarly, the jassid population was relatively higher 1.89, 1.83 and 1.79/ leaf on Moro chilly, Talhari and Mirch shehzadi respectively on 19th February. The population was higher 3.24, 3.04 and 2.58 aphids/ leaf on Talhari, Moro chilly and Mirch shezadi varieties respectively on 25th January. The predators’ population was higher 1.61, 1.53 and 1.33/ plant on Moro chilly, Talhari and Mirch shezadi varieties respectively on 9th February. Since pest population increased beyond ETL on 25th January. Therefore 2% neem seed extract was applied. These applications kept the pest population below ETL.
Contribution/ Originality

Abstract
Customer demands fluctuate over a different time horizon and if forecasted with same forecasting method shows errors in production planning. A linear programming mathematical model is reformulated in this paper for aggregate production planning (APP) to find the best-suited forecasting techniques for different market demand scenarios. The model is reformulated as a linear programming model and solved using excel solver to minimize relevant costs (backorder cost, inventory cost, and regular time production cost) while meeting the forecasted demand. The system performance is evaluated on the basis of service level (SL) and inventory level (IL). A case studied from a silk industry of Bangladesh used here to define three demand scenario High, Peak and Few. For each of them, the service level and inventory level was compared with the inclusion of simple moving average (SMA), weighted moving average (WMA) and simple exponential smoothing (SES) forecasting methods in the APP model. We found from the computations that for High and Few scenarios SMA is best in terms of SL and IL but for Peak scenario, WMA is best in terms of IL.
Contribution/ Originality
The paper's primary contribution is reformulating the linear programming mathematical model including regular time production cost in the objective function, using the WMA and SES as forecasting techniques, and using the Excel Solver for solving the APP model which are different from other works.
