Automated Production Scheduling System   Production management became more complex while the scale of manufacture reaches certain level. Nevertheless, in the technology industry, it is too complex for scheduling production through manual control and its usual consumes much stamina from members of production management, these situation caused members remain no more energy to engage in other production improvement activities. As the operation of production become more and more complex that the tasks of production scheduling not only overtake the capability of workers, but also can’t reach time-effectiveness. There are many uncertain factors affecting the production procedures in factory. For example, the emergency orders of customers, production line ceased by lacking of materials, maintaining for production equipments in schedule or unpredicted...etc. It must be promote the automation of production scheduling to respond to varieties. That can help staffs of production management quickly react to adjust production schedule which depends on requirement of orders and circumstance of production line.                      The attribute of low volume and high mix for customization products which exams the ability of production scheduling. Moreover, this form of production is practiced by YENOM for realizing the long-term strategies of services.     Depending on variety of experience of production management in different industries, even in the same industry that has shared this issue. In the aspects of control interface and function of foreign package software, these are almost hard to meet all the requirements of industries in Taiwan. For this reason, that raised higher barrier significantly for implementation of production scheduling system. In order to improve the effectiveness of production management, YENOM is continuously thinking about how to computerize the experience of production scheduling for developing suitable production scheduling system to itself, which hold YENOM’s attributes of rapidly, flexibility, immediate production after received order, and the requirement of high quality service. That will be impeccable while production line extended in the near future.          The benefits of computerized production scheduling are as follows: Increasing precise of delivery date, enhance quality of customer service.    Response to variable factors rapidly and strengthens coping ability for factory management.    Reducing the requirement of labor force for production management and promote production efficiency.     The new automation planning is on the way in recently, which function is “electronic presentation board”. It can benefit to production procedures by rapidly and accurately submitting critical production information of customers to production line.
