Abstract: A scheduling computer system optimizes the match between allocation of processes and resources. To do so, the system temporarily allocates the resources to a process selected based on the attributes of the resources and the processes, as well as the processing start and desired processing end times. In doing so, the system avoids selecting processes to which resources have been already allocated. The system also determines a resulting time value and a resulting fitness value based on the temporary allocation. Using the resulting time value and the resulting fitness value, the system determines the optimum resource for a particular process and allocates the resource to the process accordingly. The system also generates a scheduling chart illustrating the resource allocation.

Abstract: Constraint evaluation system, expert system, and constraint evaluation method for evaluating an allocation proposal, in which the job combinations are selected for individual evaluation to test if each combination is consistent with a constraint. This shows whether there is a restriction in which one of the jobs of a combination is determined uniquely by the other job of the combination. When a restriction is detected, the current value, which has the restriction, is replaced with the restricted value of the job which is uniquely determined by a one-to-one dependency relation. After the individual evaluation associated with the restricted job is performed, a job other than the other job of the combination is selected.
