การปรับปรุงตารางการผลิตในกระบวนการผลิตชิ้นส่วนหม้อแปลงไฟฟ้า

Abstract

The project is an example of factory business, product design, manufacturing, distribution, product testing, inspection and maintenance switch cabinet. Switchgear cabinet load break switches transformer tank It was found that the production of components of LBS transformer plant samples that showed the unemployment problem and there is no production scheduling procedures and methods of production scheduling efficiency. The analysis found that the cause of the problems caused by lack of planning and control in the production schedule. Paying job without planning ahead. The preparation has improved the production schedule for the LBS products to reduce the time of unemployment. By the heuristics used to plan the production schedule. The rules adopted 3 is selected at run time minimum (Shortest Processing) choose a job at a lot of hard work (Longest Processing) and the remaining lot of hard work to do before (Most Work Remaining). it also prepares the route card to specify the name of the product and process components, power transformers. The analysis results showed that after the improvement plan production schedules most work remaining can increase machine went from 68 percent to 79 percent and from 125 hours to 122 hours.
