Scheduling system and method

Abstract

The present disclosure provides a scheduling system and method. This method includes steps as follow. A communication device is connected to a plurality processing stations and receives instant process data of each processing station, where the instant process data includes a main program number and a processing time. According to target yield, delivery time and the instant process data of the processing stations, production line scheduling is calculated, and an estimated production is forecasted. It is determined that whether the actual production of the production line scheduling matches theestimated production. When the actual production is lower than the estimated production, based on the instant process data, a bottleneck station is determined from the processing stations. The machine diagnosis is performed on the bottleneck station to identify an abnormal cause. If facilities with a same function can replace the bottleneck station, a scheduling decision system selects a same facility as a processing station, if there is no facility with a same function, the scheduling system notifies related staff to maintain the bottleneck station, and the overall scheduling efficiency is improved.

Description

technical field [0001] The present invention relates to a computer system and method, and in particular to a scheduling system and method. Background technique [0002] Capacity planning is to provide a method to determine the size of the overall production capacity formed by the combination of capital-intensive resources, such as: equipment, tools, facilities and overall labor force size. [0003] In the past, capacity planning was mostly a static model, and planning and scheduling could be carried out after setting production and manufacturing related data through the production scheduling system. During continuous production and manufacturing, if a certain process equipment is abnormal, defective semi-finished products will be produced or production efficiency will be reduced, which will affect the subsequent processes, resulting in a decline in yield and output. [0004] In addition, most of the current scheduling systems or methods are aimed at increasing production an...

Problems solved by technology

[0003] In the past, capacity planning was mostly a static model, and planning and scheduling could be carried out after setting production and manufacturing related data through the production scheduling system. During continuous production, if a certain process equipment is abnormal, it will produce defective semi-finished products or reduce production efficiency, which will then affect the subsequent processes, resulting in a decline in yield and output.

[0004] In addition, most of the current scheduling systems or methods are aimed at increasing production and stabilizing delivery. However, different factories and production processes require different scheduling objectives. Therefore, the production goal can only be increased with increasing production and stabilizing delivery. Scheduling systems and methods have been unable to meet the needs of most factories
