Developing Automated Production Management System for Manufacturing Green IT Products

Abstract:

This paper presents a scheduling method for a semiconductor wafer fabrication to meet daily quantities of orders with multiple product types and different due dates. Since each order has a due date, a quantity to be produced and a product type, a production planning is made to satisfy meeting due date and quantity of order. By a production planning, the daily output quantities (to be transported to wafer probe facilities) and input quantities for all product types are determined and lots associated with orders are released to a fabrication. Although production planning is obtained, it is not easy for operators and manufacturing managers to observe production planning since the unexpected incidents, such as machine breakdown, operators' mistakes and preventive maintenance, occur frequently. Therefore, it happens frequently that actual daily output quantities of orders are different with the planed ones. In this paper, to satisfy production plans in real fabrication, efficient dispatching rule that can be used in scheduling and dispatching in manufacturing execution system for a semiconductor fabrication developed.
