Abstract: A computer system holds model management information for managing a model for calculating, based on a feature amount of a process pair generated based on a plan history and formed of two processes, a transition probability of the two processes forming the process pair. The computer system comprises: a transition probability calculating unit uses, in a case of receiving input data including a plurality of target processes, the model management information and a feature amount of a process pair formed of a reference target process and a transition destination target process, to thereby calculate a transition probability of the process pair; and a transition probability modifying unit modifies the transition probability of the process pair determined to be unreliable. The transition probability calculating unit generates a new plan by determining the order of execution of the plurality of target processes based on the transition probability of the process pair.

Abstract: A scheduling system generates a schedule formed of the entries, which are ordered by using a model for calculating a probability of selecting one of the entries. A computer system, which verifies the scheduling system, comprises: a selection module selecting at least one of the entries based on the target data for verification; a feature amount calculation module generating feature amount data formed of each of the entries; a feature amount estimation module estimating a feature amount which is a feature amount not included in the feature amount data; a selection probability calculation module calculating a probability of selecting the at least one of the entries; and an effect estimation module executing selection processing of selecting a candidate entry to be included in the schedule based on the selection probability, and generating information indicating a search range of the scheduling system based on a result of the selection processing.
