| Summary: | 博士 === 國立交通大學 === 工學院工程技術與管理學程 === 101 === In a competitive market environment, customer demands are gradually changing. Factory management planning and scheduling are also key issues that require special attention.
Today’s customers demand customized products instead of mass-produced goods and companies opt for larger product variety rather than a few products that are manufactured in large quantities. Businesses focus on high-quality services to win the approval of customers. Companies strive to adjust to these market developments. They have to rely on applied management techniques to prevent or reduce the incidence of undesirable phenomena which may occur during production activities such as delayed delivery of orders, urgent orders that have to be given priority, delay of production due to a large number of manufacture orders, shortage of raw materials, changing production sequences on a whim, high production or storage costs etc. This study examines the factors that prevent the successful implementation of actual operations after the adoption of a new Advanced Planning and Scheduling (APS) software system in addition to the utilization of a TOC management system to achieve gradual improvements and identify system constraints. Businesses have to decide how to exploit constraints and subordinate everything else to the above decision to make adjustments to the system and elevate the system’s constraints. If a constraint reverts to its initial state, inertia should not be allowed to restrict the adoption of the five focusing step approach. This helps prevent the repeated occurrence of constraint inertia and ensures a smoother operational flow.
A continued application of the five focusing step approach shows more completed transfers in the production processes. Due to the fact that the volume and quantity of work orders cannot be compared in this particular case, the results clearly show a variation in the completed volume before and after transfer.
