Abstract

In a labor-intensive cell manufacturing system, effective training is an important issue. We have proposed "skill index" as a new human index in the previous study. We have also proposed operator allocation method using this index for effective training up to now under the stable order condition. However, the order condition is fluctuating in a real site. Since this method did not change task assignment, operators had to continue the same tasks after they became expert about assigned task. It has a potential which becomes the big restrictions under fluctuating order condition. In this study, we make a new operator allocation and scheduling method for fluctuating order condition. In particular, we add a new variable for representation of quantity in decision variable of task assignment. The operators have various tasks and we have to consider about the simultaneous tasks, parallel tasks and the preceding restriction for other operators in the same cell under scheduling method. As a result of the computer experiment, our new method can get the task assignment and schedule which achieve more effective training than the previous study.
