Abstract
Ethiopia has a comparative advantage in the leather and leather products producing industry. Universal leather products factory, is one of the industries in the leather goods and garment subsector. An earlier study showed that the capacity utilization for leather products producing firms is low as 48% and this could arise from a number of factors such as high in-process inventory, long manufacturing lead times, different part design and process plan for similar parts etc. Group technology is a manufacturing philosophy which advocates simplification and standardization of similar entities. The main purpose of the research is production performance improvement using group technology approach in universal leather products factory. After the necessary data and information was collected form the factory. Pareto analysis is used to select some of the major products produces by the factory. Visual Studio/Visual Basic.Net software is used to come up with group technology problem of parts classification and coding. Direct clustering method is used for identifying part families and associated machine groupings. Arena software is used to model and simulate the newly developed machine cells. The major findings of the research were: a 10-digit hybrid code structure technique was developed and standardized for coding of the products in the factory. Each of three part families with associated machines were formed in both of the leather goods and leather garment production centers. The newly formed GT cells were modeled and simulated. In the new GT approach, the time needed for designing of specific product reduced by 72.2%, the manufacturing lead time reduced an average percentage of 74.8%, distance traveled by the parts during manufacturing reduced by an average percentage of 34% and WIP inventory reduced by an average percentage of 55%.
