Application Of The Jit In The Semiconductor Manufacturing Operations Management

With the competition increasing sharply,enterprises have started to pay attention to the efficiency of product manufacturing to improve the comprehensive competitive power by reducing the cost.It refers to many aspects such as managing inventory, shorterning cycle time of manufacture,quality control,etc.The thesis addresses just-in-time(JIT) approaches for manufacturing planning and control(MPC).Many definitions have been put forward for JIT,and they have been evolving as JIT is being globally adopted.Several of the more popular current definition focus on JIT as an approach to minize waste in manufacruring.The focus is so broad as to be of limited use.A usefulcommon denominator running through this and other JIT definitions is a broad philiosophy of puring zero inventories,zero transaction,zero defect and zero disturbances.Another physical program associated with JIT has been pursuit of improved quality through process improvement.Most JIT firms have enlarged in programs of quality awareness and statistical process control.In a repetitive manufacturing system,any quality problem will result in a stoppage of the entire flow line.In a JIT program,most people now include the goal of continual improvement as a manim for day-to-day operation.Every day,each worker should get better in some dimension,such as fewer defects,more output or fewer stoppages.Continual improvement,as a cornerstone of JIT,means making thousands of small improvements in methods,processes,and products in a never-ceasing quest for excellence.You are supposed to find the most attractive feature of this thesis is that it lays the foundation of JIT relevant theories and know how,as well as validate them with the combination of a real case implement and analysis in semi-conductor manufacture industry.
