The Research Of Chipset Manufacturing Enterprise For Improving Cycle Time

With the increasing of market competition, companies focus more and more on market response speed and cost control. For those manufacturing enterprises, cycle time directly determines the enterprise's responsiveness to market demands; meanwhile, improvement of cycle time will result in reduction of finished goods inventory, which will directly reduce financial cost and management cost. Therefore, for any manufacturing enterprise, improving cycle time is a very important issue that must be considered.The paper mainly studies on how to improve cycle time for a manufacturing enterprise. H is a leading chip manufacturer, whose main product is microprocessor. The product has the portraits of processing is complex; products are small, expensive, and processing large quantities and so on. This paper mainly analyzes how to improve cycle time by WIP managementFirstly, this paper analyzes the methods and ideas of how to improve cycle time and points out that the key to improve cycle time is to reduce WIP level for every workstation of production line. Then, it comes out the upper limit and lower limit of WIP for all workstations based on historical data, cycle time goal and the bottleneck workstation will not idle due to lack of WIP. At the same time, this paper verifies the lower limit which will ensure that the bottleneck workstation will not idle due to lack of WIP. It also establishes and implements a closed-loop dynamic WIP control model to guide the actual production management to achieve the cycle time goal.
