    Cluster Development for Metal Work Industries: Case Study on Addis Ababa Micro and Small-Scale Metal Work Industries
    (Addis Ababa University, 2011-11) Tariku, Tamiru; Daniel, Kitaw (PhD); Gulelat, Gatew (Mr.) Co-Advisor
    The contribution of micro, small and medium Scale industries towards employment generation, alleviation of poverty and inequalities and development of backward areas is recognized worldwide. Although, these industries have great role in economic development of our country, they doesn‟t benefit as their potential due to their problems related to their size. Most of the problems are lack of: market, skilled manpower, working capitals, information and low level of competitiveness. In addition there is lack of cooperation among themselves, which limits sharing of resources between them. Micro and small industries clustering is a group of these industries, producing similar products, located in a geographical proximity, sharing resources (like knowledge, technology etc) among themselves in order to overcome their internal and/or external challenges, and that compete each other but also cooperate with one another. The study is concerned on cluster development of micro and small metal work industries in Addis Ababa city. It covers 32 micro and small scale metal work industries selected from all sub cities with the objectives of developing micro and small metal work industry cluster to create a conducive environment for the development of inter-firm cooperation, improve the competitiveness of the industries, to solve marketing problems of the industries, and to facilitate metal work technology transfer to the country. For the accomplishment of the objectives of the study the selected industries were assessed through questionnaires, interviews and observation. The results obtained from the survey shows that Addis Ababa micro and small metal work industries faced with the following problems. These were:- lack of: market, product displaying area (marketing area), working capital, technical training, trust among the metal working industries; and flexibility of price and quality of raw materials. In order to solve the observed problems with the support of published and unpublished literatures the study proposed the development of micro and small metal work industry cluster and identifies suitable cluster location in the city. Taking into consideration of other countries experiences, for realization of the benefits of developed metal work indus

    Improving Addis Ababa Transport System by Using Transport Demand Management Strategy
    (Addis Ababa University, 2019-10) Sisay, Weheyaga; Birhanu, Beshah (PhD)
    Addis Ababa is challenged by providing access to safe, efficient and sustainable transport system. Congestion is becoming a common experience in different parts of the city due to the lack of consistent concentrated efforts from the various stakeholders. The city is critically inadequate to provide service for the increasing travel demand of the city. This research explores methods of minimizing Addis Ababa transport system problem by using transport demand management strategies. Transportation Demand Management (TDM) refers to the various strategies adopted to change travel behavior to increase the transportation system efficiency and also to achieve reduction in congestion, fuel conception, environmental pollution, while focusing on the safety and mobility of the road users. In order to select applicable demand management strategy the first step is to identify behavior of major Addis Ababa transport problems. Primary and secondary data has been used to identify behavior of major transport problems. The behavior and effect of this problems have been described using system dynamics causal loop diagrams. After identification of Addis Ababa transport problems Qualitative comparative analysis is used to confirm applicability of transport demand management strategy. Applicable transport demand management strategy has been selected by considering correlation between Addis Ababa transport demand management barriers, transport demand management strategy and Addis Ababa transport problem behavior. Customized QFD analysis is performed to measure relative importance of selected transport demand management strategy with transport service quality measuring parameters and prioritize the transport demand management strategies. Math lab Digital image process analysis is used to analyze traffic intensity of typical traffic congestion of Addis Ababa. Input of Math lab analysis is image collected form Online Google traffic monitoring webpage. Typical traffic condition data is collected for 17 hour per day for every week day. Math lab digital image analysis identifies traffic intensity of Addis Ababa with respect to week days and every season of the year. The result analysis shows decrease of traffic congestion by 17 % to 31 % .Finally based on result of analysis space (location) and time of application of selected transport demand management strategy is identified.
