    IT ADOPTION MODEL DEVELOPMENT FOR SUPPLY CHAIN MANAGEMENT: CASE OF ETHIOPIAN MANUFACTURING FIRMS
    (Hawassa University, 2018-10-22) TAMIRU TESSEMA
    In the 21st century companies are required to continuously upgrade and improve their business activities in order to survive and achieve their business goal. One of the competition areas is an effective and efficient information flow along supply chain (SC). The information technology (IT) is one of the biggest enablers of the modern Supply Chain Management (SCM). However, SC systems in Ethiopian Medium and Large-Scale Manufacturing (MLSM) Firms found as fragmented SC, poor information exchanges, outdated systems and paper work. The purpose of this study is to examine IT adoption status and to develop its adoption model to Ethiopian MLSM firms. Cross-sectional survey was conducted on 438 samples from total 2,758 Ethiopian MLSM firms. Both a qualitative and quantitative data were collected using questionnaire survey, interview and document investigation, then descriptive and inferential statistical analysis were conducted by using Statistical Packages for Social Science (SPSS) version 21 and Microsoft office excel. The results indicated that the IT adoption status among Ethiopian MLSM firms was inadequate at all, despite good improvements in adopting some IT tools such as the Internet, Intranet and Barcode Scanner. The result also shows positive and strong correlation between the role of IT adoption and SC performance with correlation coefficient r = 0.824, even though a weakness to accept sophisticated IT tools, such as ERP, EDI, RFID, etc. The study suggests firms to exploit CSFs and reduce associated challenges to adopt IT, government to support these firms by policies, infrastructure, subsidies, incentives and training and universities to focus on producing IT skilled professionals. Finally, study proposes a model of IT adoption for Ethiopian MLSM firms to enhance their competitive advantage and improve firms’ performance

    MODELING POST HARVEST LOGISTICS OPERATION OF PEPPER: A CASE OF HALABA ZONE
    (Hawassa University, 2021-10-28) BEREKET TADIWOS MENEDO
    Logistics Optimization models have been used extensively for reducing logistics costs and maximizing benefits. Those models are for enhancing the logistics chain. Post-harvest logistics operations are for agricultural logistics activity after harvest. This thesis concerns on agricultural sector post-harvest logistics operation of red pepper. The thesis was conducted on one of the Ethiopian pepper-producing area called Halaba Zone. Taking Halaba red pepper as a case study, the research attempted to analyze the existing logistics practices and distribution process of Halaba red pepper, to optimize the pepper logistics activities. Data were collected using a questionnaire, case study, observation, semi structured interview, and document analysis. The research uses SPSS software for statistical data analysis, Minitab19 software for regression analysis, Excel spreadsheet for Pareto analysis and Excel QM for LP transportation optimization model. The analysis of existing supply chain management practices indicates the availability of poor practices during logistics activities. The poor practices in logistics activities had a direct effect on pepper price inflation. In order to show correlation between price of pepper and logistics activities regression analysis conducted. The regression analysis result shows a positive correlation between logistics activities cost and price of pepper. After regression analysis Pareto analysis conducted taking four logistics activities costs as parameters. The need to conduct Pareto analysis is to give priority for greater contributor of logistics cost. Based on Pareto analysis transportation cost found as the greater contributor cost among logistics activities. Therefore transportation model built .The built transportation model can save 18.5343% of 2019/20 transportation cost of Halaban pepper. This percentile means the built model worth of saving were around 1,611,555 ETB. Based on this finding it‟s possible to conclude that measures taken in logistics activities can give positive result in minimizing price of pepper
