Item DESIGNING GREEN SUPPLY CHAIN MANAGEMENT SYSTEM FOR HORIZON ADDIS TIRE MANUFATURING P.L.C(Hawassa University, 2021-10-17) LEISO LIRANSO GICHAMOThe history of tire manufacturing goes back to early 19th century and in Ethiopia the tire manufacturing industry began in 1972 G.C, where Addis Tire S.C. is first of its kind and currently holds its new name “Horizon Addis Tire Manufacturing PLC”. However, the company being the leading tire manufacturing company, it continued to waste inputs and operated at low level of capacity resulted by different internal and external factors. In an existing status where companies eliminate wastes from their manufacturing and natural environment, HATMPLC imports almost all of its inputs from abroad followed by packaging wastes, and this is the point where the situation needs scientific inquiry and solution. The general objective of this study is to design green supply chain management model in Horizon Addis Tire Manufacturing PLC. Data is collected using interview, document review and observation approaches. Observation was made to understand and structure the tyre production process, eight detailed key informant interviews were carried out and essential documents from the company were reviewed. Data were analyzed in descriptive analyses for performance measurements and waste study. As a result, the existing supply chain structure of the company was structured, and its supply chain processes were discussed. The company is extremely dependent on import from abroad where all of raw materials, except for part of the natural rubber, are imported, and it has a production waste of about 16,129,099.4 in 2011 E.C and 14,366,005.5 ETB worth in 2012 E.C just from tire defect. The company had 55.9% and 48.9% of capacity utilization in 2011 E.C and 2012 E.C respectively, and it improved the reliability and responsiveness performance attributes while cost and flexibility attributes sustained and asset turn over and total supply chain management cost dragged down. Following this, a green supply chain management is designed through the designs of green supply chain processes in accordance with green Supply Chain Operations Reference by applying best practices. To conclude, although HATMPLC is producing essential product, its waste management performance is below its target set. The company needs a governmental attention in consideration with environmental management and market place since the company plays important role in fulfilling the domestic tyre demand and equally contribute to waste accumulation in the countryItem SUPPLY CHAIN ANALYSIS OF HANDMADE TEXTILE MANUFACTURING INDUSTRY USING SUPPLY CHAIN OPERATIONS REFERENCE(SCOR) MODEL: ACASE OF GAMO ZONE(Hawassa University, 2022-10-27) AYGOTA AKA ADAMOSupply chain management is a process of designing, developing, optimizing, and managing the internaland external components of the supply system in a consistent manner with the overallfirm‘s objectives and strategies. In today's businessenvironment, companies are operating in supply chains to increase efficiency and truly meet the customers' demand. Because of theimportance of supply chain management to compete in the current market, there is agrowing need of supply chain operation improvement to improve its process efficiency and to meet the customers’ requirements. This study aimed to analyze supply chain operation of handmade textile manufacturing industry in Gamo Zone to improve its efficiency and satisfy customers’ needs. Surveying method of data collection using interview, questionnaire and observation was used to collect the data. Both primary and secondary data were used to identify challenges and gaps of the existing supply chain management. The study utilized Supply Chain Operations Reference (SCOR) model to analyze the existing SC operations and to identify opportunities for future improvement of the supply chain of the case industry. Based on the analysis of the existing SC operation, the main challenges identified were high cost of sourcing due to prolonged supply chain process, shortage of raw material and quality problem, low production efficiency and capacity utilization, lack of modified weaving technologies, lack of appropriate production schedule, poor order and delivery management and weak marketing system. Because of these gaps of SC operation, the overall performance of supply chain of the case industry was poor. Supply chain analysis to improve the efficiency of the case industry was performed based on analysis of existing SC challenges and mapping future improvement on SC planning, sourcing, production and delivery processes using SCOR model. This improvement on SC operation can be achieved by changing source point to local potential suppliers of raw materials, minimizing the number of non-value adding SC actors by linking weavers with suppliers and consumers, using modified production technologies, strengthening direct market linkage with final product users and establishing distribution center for weaving associations in urban areas. This improvement action will minimize cost of sourcing and production, time of delivery, and increase SC efficiency of the industry to meet customers’ demandItem DESIGNING GREEN SUPPLY CHAIN MANAGEMENT SYSTEM FOR HORIZON ADDIS TIRE MANUFATURING P.L.C(Hawassa University, 2021-10-06) LEISO LIRANSO GICHAMOThe history of tire manufacturing goes back to early 19th century and in Ethiopia the tire manufacturing industry began in 1972 G.C, where Addis Tire S.C. is first of its kind and currently holds its new name “Horizon Addis Tire Manufacturing PLC”.
