Research Summary: The Study of the Cycle Time Improvement by Work-In-Process Statistical Process Control Method for IC Foundry Manufacturing

The purpose of this research is to make a cycle time improvement by used work in process statistical process control method. Firstly this study were discuss about relevant literatures to work in process management and bottleneck management, and collect previous studies and improvement methods of due date and cycle time, and collect available data, practical observations and analyses to find out matters influencing the due date and the cycle time.

When the matters are found out, a model and method which can improve current issues would be constructed, namely a concept of WIP statistical process control is led, the problems would be improved by systematic methods.

The time cycle is a critical factor for customer satisfaction because it represent the response time to the market. Long cycle time reflects the ineffective investment for the capital and will cause customer unsatisfied and order loss. The principle of improving cycle time is to reduce WIP and increase movement. The cycle time improvement is a time continuing process.

Besides cycle time improved, the production index also improved, the production line supervisor’s working load is improved too.

Research Summary: A simulation study of WIP inventory drive systems and their effect on financial measurements

The purpose of this research was to explore and compare the potential benefits of three work-in-process (WIP) inventory drives and their associated buffer management systems through the use of computer simulation. The assembly line process under study was supplied by a large anonymous manufacturing company. The study evaluated and compared the effect of the drive system on the financial measures performance. For the purpose of this study, there were no market constraints. Everything produced was sold. This ensured that the system constraint remained within...
