DESIGNING DISTRIBUTION NETWORK FOR HIGHLY DEMANDED COMMODITYCASE OF SOUTH SPRING WATER IN SIDAMA NATIONAL REGIONAL STATE
(Hawassa University, 2022-12-24) TSEGAABTESEMAHATIYA
A distribution is one of a key activity that has a direct impact on the success and the overall
profitability of a given supply chain. If a distribution of a given product managed properly, it will
have a great impact on both the success and customer satisfaction of a given SC. However, there
are many manufacturing companies in Ethiopia, most of them do not have properly designed
distribution network. This research is intended to design a new distribution network for a water
bottling company located in Sidama National Regional State Arbegona Woreda..To distribute a
given product in cost effective manner there should some decisions be made which include
number of regional warehouses, location of regional warehouse and transportation cost to and
from the regional distribution. So the research decides the number and the locations of regional
distribution centers by utilizing FAHP method. After the locations of the RDCs found, a new
distribution network will be proposed and the Transshipment was modeled based on a newly
proposed distribution network and solved by using software package find out the optimum
transportation cost. After the Transshipment model solved and optimum solution was found the
cost effective RDCs was assigned to different demand locations in the region. Finally, the new
cost effective distribution network diagram was developed and the cost of transportation was
compared to the existing transportation cost of the company to cover all demand location and the
newly designed network saves the company 13.7 million ETB annually which is being wasted
due to ineffective distribution network
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fragmented SC, poor information exchanges, outdated systems and paper work.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
EVALUATING AND RANKING FACTORS AFFECTING OPERATIONS OF DRY PORT THROUGH DECISION MAKING MODEL: A CASE OF MODJO DRY PORT
(Hawassa Unversity, 2021-10-27) SENATER ABERA MIDEKSA
Currently, there are a number of factors that affect dry port operations and these factors need
to be identified systematically in order to evaluate significant factors that are highly
constrained to their operations. In this regard, this study is aimed to identify the factors that
affect the operations of MDP and ranking according to the level of significant impact from top
to bottom by developing Analytical Hierarchical Process (AHP) model. A qualitative and
quantitative method of research approach was employed and both primary and secondary data
were collected. For primary data collection, the researcher used both probability and non probability sampling techniques in which the samples were selected by stratified and purposive
sampling respectively from the target population of MDP. Meanwhile, secondary data was
collected from published documents or databases such as books, journals, reports, official
websites, etc. This work also examines the critical factors contributing to the success of MDP
operations. Finding suggests that five main factors and nineteen sub-factors that affect the
operations of MDP were identified. From the main factors, information systems are the
dominant factor affecting MDP operations followed by service features, dry port capacity,
government policy, and hinterland conditions, which took the last place. Furthermore, from the
overall factors investigated in this study, lack of coordination between stakeholders and
inadequate customs clearance process are the influential factors ranked as the 1st and 2nd level
affecting the operations of MDP respectively. The implications of this finding suggested that
managers should pay more attention to top-ranked factors and the significance of the research
is expected to be of managerial value to dry port operators when eliminating high operational
constraint factors to improve the efficiency of MDP operations.
SUPPLY CHAIN PERFORMANCE EVALUATION AND MODELING: CASE OF SIDAMA COFFEE FARMERS‟ COOPERATIVE UNION
(Hawassa University, 2019-10-22) GASSA MAGARA MAMO
This thesis aims to propose a supply chain (SC) performance evaluation model in the coffee processing
industries: Case of Sidama coffee farmers’ cooperative union (SCFCU). Coffee is a major agricultural
export commodity of Ethiopia, particularly the Sidama Zone, which has a high potential for specialty
coffee. From Sidama Zone, SCFCU has major contribution supplying coffee product to domestic and
export market unifying 61 coffee farmers’ cooperatives and being the second-largest union in the
country. However, the primary coffee farmers’ cooperatives are facing enormous challenges at the
current time in sourcing methods and production processes decreasing SC performance associated with
quality of raw material and costly production making them unable to be a competitive and unprofitable
business. They have no suitable SC performance evaluation model, standardized business operation
process and methods that can improve their inter-organization and SC performance in a sustainable way.
To solve these problems, the thesis study on SC performance evaluation and modeling was conducted. To
achieve the study goal, investigation and reviewing of an appropriate SC performance evaluation model
were carried out to have comprehensive knowledge. From several SC performance evaluation models,
the SCOR model is identified as an appropriate SC evaluation model being dynamic, balanced and
universal model. Significance of the study, using the SCOR model is believed to give an insight for the
primary coffee farmers’ cooperatives as well as other concerned bodies about the existing challenges of
coffee processing industries SC suggesting possible solutions to the problems and enabling them to
improve SC performance. Because SCOR model designated to analyze SC performance and optimize the
various processes in SC and it can play an important role in identifying problem-solving ways being
starting points to find better ways to improve SC performance, in coffee processing industries making
them more optimal and sustainable performance improvement. To achieve the study goal, a descriptive
research design was employed and 13 cooperatives were selected unified in SCFCU from Sidama Zone
in five Woreda within three clusters from the total population 182, the sample size was 125 respondents
using Yamane sample size decision model and random sampling system. The primary data were collected
using semi-structured questionnaires, interviews and field observation. Secondary data were collected
from different published and unpublished sources. Data analysis was on the basis of qualitative and
quantitative research approaches. The result was a high performance of reliability and responsiveness,
the poor performance of Plan and Source process having moderate overall SC performance. Using the
study result, SC modeling was made considering suitability for coffee processing industries. Finally, from
data analysis and result discussions, conclusions were drawn and recommendations made on gaps
FACILITY LAYOUT DESIGN TO EFFICIENT SPACE UTILIZATION AND INSPECTION PERFORMANCE: CASE OF MODJO DRY POR
(Hawassa University, 2018-10-17) BONDE ASSEFA SHULISHA
Ethiopia is landlocked country which uses the Ethio-Djibouti corridor the main outlet to the sea. However, this generates high demurrage cost at Djibouti port. To overcome these challenges, Ethiopian government established about eight dry ports in Ethiopia. From those, the Modjo dry port is large and 95 % of goods are flow through it. This makes congestion in the warehouse and terminal due to lack of suitable facility layout for inspection performance. So, this paper proposes an alternative facility layout design of warehouse. This done by using primary and secondary source of data which collected from warehouse managers, drivers, loading and unloading labors, customers of Modjo dry ports. However, the researcher use surveying, different journal, website and report from dry port as basic inputs for models to propose modified alternative layouts. The models used were classified in different levels regarding their compatibility to execute paper works as per requirement. Those were mathematical, Computer aided design model (AutoCAD) and simulation Model. The mathematical model was mainly used to calculate areas, volumes of existing and modified alternative layouts of the warehouse. The AutoCAD model was used to draw out the alternative facility layouts by feeding the input data collected from field survey by using Global Positioning System GPS and dimensions measured by using standard meter. The results of the study were validated by descriptive event simulation software which is known as any logic software. Finally, depending on the result of simulation, and model output of AutoCAD the alternative layouts were proposed. The capacity of space dedicated for existing warehouses could accommodate the 120 TEU. However, for the alternative layouts of I, II, III & IV are 564, 752, 556 & 796 TEU respectively. Depending on these results the alternative scenarios were proposed in order to mitigate the challenges facings to Modjo dry port. The contribution of this study is to realize the gaps of knowledge in using pallet racks for space utilization with aisle or passageway in the warehouse and point out the future research directions in facility layout design to efficient space utilization and inspection performance around the dry port area
