A major challenge in designing and controlling flow lines is to achieve high customer service level while stay lean. Just-In-Time (JIT) manufacturing approach has triggered various 'pull production system', such as CONWIP or Kanban controls, which emphasizes on response to demand rather than forecasts. We identified and documented the anatomy of various pull type control policies. Based on the analysis, we designed a new class of control policy called Extended CONWIP Kanban control (ECK). We conducted comprehensive simulation comparison studies. Simulation results showed that the new control policy can achieve higher service levels with lower inventories than other policies including hybrid ones. We developed a state space comparison methodology to compare various policies with that of optimum solution. Our analysis reveals that our ECK policy provides the most adjustment flexibility toward the optimum. We also proposed a parameter design procedure and an adaptive parameter adjusting system. A case study verifies the advantages and utilities of the ECK policy. Beside the cost savings, another major advantage of the ECK policy is its robustness. That is, the total cost of the ECK policy is less sensitive to demand or system variations.

There are many business in Taiwan that their production type are indistinct between make-to-stock and make-to-order. This kind of production type can shorten the lead time of order and decrease the fluxion of customer¡¦s demand, on it¡¦s technology of predicting customer¡¦s demand for pre-production and inventory. Thus, the efficacy of production must depend on it¡¦s precision of predicting customer¡¦s demand. Recognition that traditional work order dispatching made to some specific standardization. Therefore, it is leaded to customization product and less flexible. And the decision-maker must choose one goal between minizing inventory cost, WIP¡¦s level and lead time. The production type, work order dispatching must have flexibility,and it must accomplish the customer¡¦s order on time considering inventory cost and customer service. This thesis hopes that it would be to develop a work order dispatching method to improve the efficiency of WIP administering, the flexibility for work order dispatching and decreasing lead time of customer¡¦s order. According to production¡¦s characteristic of different manufacturing stage, it can create one applicable dispatching rules to increase the production efficiency. Finally, using simulation software, applying to case study comparing the performance of the real case and new work order dispatching
