The resulted number of labor from applying the KBS is equal to that of the integer-programming model. This means that we reach the optimum solution.
The KBS has the advantage of distributing the surplus workdays evenly among days and labor.
In this work, we presented a knowledge-based system built using Visual Prolog V5.2 to solve the tour-scheduling problem in continuous-operating facilities which include hierarchical workforce.
The proposed method is very efficient since its results are the same as integer-programming models.
