ABSTRACT
Toyota manufactures a variety of automobiles with many di£erent specications. Each type of car is always subject to ²uctuations in demand. For example, the demand of car A might decrease, while at the same time, car B might increase in its demand. ™erefore, the workload at each car line in the plant must be frequently evaluated and periodically changed. Continuing an example, a number of workers at the line for car A would have to be transferred to the line for car B so that each line can adapt to the change in demand with the minimum necessary number of workers.
