Now, these conditions are merely prerequisites. Few businesses exist today without offering this requirement, and the key competitive factor has become speed. Major businesses have been trying to adopt new business initiatives in order to stay alive in the new competitive market place, and there is no question that the elimination of waste is an essential ingredient for survival in today's manufacturing world. Companies must strive to create high quality, and low cost products that can get to the customers in the shortest time possible. Just-in-time production system is one of these initiatives that focus on cost reduction by eliminating non-value added activities. The tools and techniques of JIT have been widely used in both discrete and process industry starting with the introduction of the original Toyota production system. This thesis addresses the implementation of Just-in-Time production system with focus on AMCE and AABGF. The goal of this research is to investigate how JIT can be implemented in these companies. This thesis attempts to introduce JIT from its conception, and many collaborative JIT concepts, components, elements, and tools that are used for the elimination of wastes are addressed. To develop the implementation model first the status of the companies were investigated and then the problems are identified and x formulated. The JIT implementation guidelines developed by APICS and others have been seen to develop the line implementation model of JIT for the companies. It has been seen that only a hybrid (Push-Pull) JIT systems is applicable to both companies. In the implementation model developed, Value stream mapping was used as a tool. The companies can use it to identify various types of waste in the value stream of the company and try to take steps to eliminate them. Finally the conclusions and recommendations are provided for the thesis.enIndustrial EngineeringThesis
