We developed a production scheduling system for batch plants. This system supports human intelligent works by using the auto scheduling on the system and the manual modification or the rescheduling cooperatively.
The scheduling system which works well in various situations at factories must have some flexibilities as follows. 1) A scheduling system has a frame to reflect user requests easily. 2) A scheduling system has a function to modify scheduled results to satisfy user's expectation.
They are realized as follows. 1) We add a customize function to incorporate a individual plant's know-hows into the auto scheduling strategy. 2) We develop the flexible user interface to cooperate with user and the function of manual modification.
In this paper, the problems for practical use are summarized and the effects of this system are demonstrated by the field test in a chemical plant.
