    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.

    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

    MODELING AND ANALYSIS OF THE DRY PORT TRANSPORT LOGISTICS PERFORMANCE: A CASE OF MODJO DRY PORT
    (Hawassa University, 2023-10-13) HUNDUMA BERSISA
    To encourage the country’s economic development, import/export trade is a better and more cost-effective way are using dry ports. Dry Ports are the specific sites to which imports and exports can be consigned for inspection by customs and which can be specified as the origin or destination of goods in transit accompanied by documentation such as the combined transport bill of lading or multi-modal transport document. However, the management of trucks, loading and unloading time, processing of custom duties, port machinery productivity and dwelling time, etc. were the problems at MDP. the research problems in addition were delays at checking points, temporary storage and transport cost at inter-terminal. Therefore, this research was conducted with a model and analysis of Modjo dry port transport logistics performance to overcome the factor affecting the efficiency and effective of the transport logistics in the port. To overcome the problems, primary data collection methods (Site survey: observation, data record, questionary and interview) took place with the help of the company’s workers cooperation whose answers questionary properly 117 of 146 considered in the research. The secondary data source (Text books, articles, journals, theses, and company documents) was used for preliminary identifying the problems and validating the study after the results were analyzed. The raw data collected through different tools in the research were analyzed with the help of SPSS, Excel, and QM for windows software packages. The analyzed data was shown by percentage, mean, table, chart and graphs and the results were shown by graphical and mathematical models. After the results obtained were analyzed and discussed, the research questions; the model of the transport logistics performance, and the performance of its operations were answered. In these results, different performance indicators and their attributes were modeled from the existing model with modifications, in terms of checking points (in-gates) an additional in gate and two other reach stackers at temporary storage will be necessary to be assigned, and the terminal transports should be directly delivering the cargo through CFS to the customers for cost and time optimization
