Abstract
Traditionally, a manufacturing business competes on price, variety, and after
service. 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.
