BOTTLENECK DETECTING DEVICE AND BOTTLENECK DETECTING PROGRAM

摘要

A handling-period determining unit (112) determines, for each machine type and production step pair, a handling period during which the production step is to be performed, on the basis of a production due date for the machine type, the number of items to be produced for the machine type, and a handling time per unit number for the production step in a production procedure for the machine type. A device-to-use determining unit (113) determines, for each machine type and production step pair, a production device that is to be used in the production step as a device to use, on the basis of production device data indicating one or more production devices for the production step. A usage-time calculating unit (114) calculates, for each production device, on the basis of the handling period for each machine type and production step pair as well as the device to use for the machine type and production step pair, a usage time of the production device in a target period. A bottleneck detecting unit (115) discovers a production device that constitutes a bottleneck in the target period on the basis of the usage times of the individual production devices in the target period.
