    Institutional Factors Affecting Loan Collection Performance of Development Bank of Ethiopia: The Case of Addis Ababa, Head Office
    (A.A.U, 2021-06) Terefe, Kidist; Abate, Sewale (PhD)
    This study assesses the institutional factors affecting loan collection performance of Development Bank of Ethiopia. The institutional factors are categorized as Staff-related Factors, Policy-related factors and Management Information System-related factors. The study employs Descriptive Research Design and applies quantitative research approach to analyze and interpret the findings. In addition to reviewing the annual report of the bank as a secondary data, 50 questionnaires were completed by respondents who are staff members in different departments. As a result, Development Bank of Ethiopia's loan collection performance has been assessed to have significantly higher loan default rates. Based on the findings of the study, the major institutional factors affecting loan collection Performance of Development Bank of Ethiopia are Poor credit scoring and poor valuation of collaterals, ineffective monitoring and controlling of debtors, policy ineffectiveness in creating improved loan collection, restricting loan concentration and favoring loan diversification, , inefficiency of Management Information System in making ease of administrative tasks, improving the Bank’s loan collection performance, aiding operating efficiency, aiding controlling task of problem loans and lack of supervision schemes. It is recommended that Development Bank of Ethiopia should focus on upgrading its Management Information System so as to improve its loan collection performance. It is also suggested that DBE's Management Information System should include a problem loan management system.

    Nonlinear Transportation Problems
    (Addis Ababa University, 2007-08) Terefe, Kidist; Guta., Berhanu(PhD)
    Some times there may be many di®erent ways to model a particular problem, choosing the best one minimizes the complexity of the problem and time to solve. Since, as we have said earlier, any programming problem with constraint matrix structure the same as the transportation problem is regarded as a transportation problem regardless of it's physical meaning and because of it's simple structure, modeling problems as transportation problems requires much less e®ort to solve than that of modeling it di®erently. In this thesis the nonlinear transportation problem is considered as nonlinear pro- gramming problem and algorithms to solve this particular problem are given. The ¯rst algorithm is similar to that of the transportation simplex algorithm except the nonlinearity assumption. The second algorithm is dependent on the simplex algorithm of Zangwill [32] that we modi¯ed it to use the special property of the coe±cient matrix of the transportation problem so that we may take shortcuts to make problem solving simple. However the algorithms are not been compered to other previous algorithms. Therefore in the future further work must be done : 1. To measure the e±ciency of the algorithm. 2. To check how near the solution of the approximated problem of the piece- wise linear transportation problem is to the optimal solution of the original problem. And ¯nally 3. to implement the algorithm to the real world problem.
