PROBLEM TO BE SOLVED: To accurately estimate execution time even if an exclusive condition is defined at a time of executing a plurality of workflows.SOLUTION: A device of the present invention: generates a case in response to a range of execution time of each of modules in an order of the modules included in each of a plurality of processes for each process; executes first determination processing for determining whether exclusive waiting occurs between a plurality of cases related to a plurality of processes; executes processing for setting the exclusive waiting to the case in the process to which the exclusive waiting occurs if it is determined that the exclusive waiting occurs while developing time; and estimates execution time in a case of executing the processes. The first determination processing includes second determination processing for determining whether there is a probability of the occurrence of the exclusive waiting; and processing for determining whether the exclusive waiting occurs on the basis of a processing result of the second determination processing. Furthermore, if it is detected that there is a probability of the occurrence of the exclusive waiting, the second determination processing is recursively executed to the case having the probability of the occurrence of the exclusive waiting. |
