A location plan is created by associating a plurality of locations and a plurality of periods with a plurality of tasks indicated by the task set 11 of the task information 10 (step S2). The location plan further satisfies the conditions corresponding to the plurality of tasks in the condition set 16 and the total resource consumption consumed by the plurality of tasks exceeds a predetermined capacity. Created so that there is no.

  The place planning apparatus further refers to the task information 10 and calculates a plurality of evaluation values corresponding to the plurality of tasks indicated by the place plan. For the evaluation value corresponding to a planned task among the plurality of evaluation values, the location and period of the planned task are substituted into a calculation formula indicated by the index corresponding to the planned task in the evaluation index set 17. The value calculated by doing is shown. The place planning apparatus calculates an evaluation function based on the plurality of evaluation values (step S3). The evaluation function indicates a numerical value indicating that the smaller the value, the better.

  The place planning apparatus again calculates another place plan different from the place plan by using the annealing method (simulated annealing method) based on the evaluation function (step S2). The place planning device calculates the evaluation function again based on the calculated place plan (step S3).

  The place planning apparatus detects when the place plans are sufficiently large enough to calculate the optimum place plan having the smallest evaluation function, that is, when the annealing method has converged (step S4, YES), step S2 and step S3 are repeatedly executed.

  According to such a place planning method, the place planning apparatus can satisfy a predetermined condition and more easily create a more preferable place plan. The place planning apparatus further makes the optimum place plan faster and more stable compared to the place planning method in the above-described embodiment, that is, compared to the case where the place plan is created by the user. Can be calculated.

  The place planning apparatus can also calculate an optimum place plan using another algorithm different from the annealing method. Examples of the algorithm include GA (genetic algorithm) method and local search method. In this case as well, the place planning apparatus can similarly calculate the optimum place plan more stably at a higher speed.
