ABSTRACT
In the real production world, the scheduling procedure applied in any particular industry is usually complex, and only understood by the personnel fully involved. The responsibility of the scheduler is to determine when and what resources are required for the jobs to be accomplished. It takes time for a new scheduler to acquire the necessary expertise and skills from an experienced scheduler and understand the working environment. Generally, the experienced scheduler will retain his knowledge and expertise in memory, and produce a workable schedule by relating the status in the production shop floor to this data bank, in which the reasoning process is implicitly logical. Therefore it is possible to foresee the problems that could occur if the experienced scheduler was unavailable.
