Production index information generating device, program therefore, and production information generating method

摘要

A control unit (120) of a production index information generating device (100) groups, based on log information of a production device, processing targets to generate groups for which end time of processing falls within a predetermined interval, classifies the processing targets contained in the groups into classes based on a number of the processing targets contained in each of the groups, generates cycle time information for each of the classes, which specifies cycle time of each of the processing targets contained in corresponding one of the classes, and determines a production capability of the production device. Accordingly, an index specifying a capability of the production device may be obtained with ease.

1. A computer-implemented production index information generating device, comprising:
a storage unit, configured to store log information, the log information including information that specifies:
a production device;processing targets processed by the production device;a start time, that indicates when processing on the processing targets starts; andan end time, that indicates when processing on the processing targets ends; and a control unit including a processor, configured to perform the following processing tasks:
group the processing targets identified by the log information, into a plurality of separate groups, such that the end times of processing targets in each group fall within predetermined threshold values;classify the processing targets contained in the groups into classes based on a number of the processing targets contained in each of the groups;generate cycle time information for each of the classes, which specifies a cycle time of each of the processing targets contained in corresponding one of the classes, wherein the cycle time is calculated based on an interval between the start time and the end time specified in the log information;output the cycle time information to an output unit in a predetermined display form; and based on the cycle time information, in a coordinate system having one axis representing the cycle time and another axis representing a number of the processing targets corresponding to the classes, the control unit selects, for each of the classes, cycle time which corresponds to one of the processing targets contained in a corresponding one of the classes, as a reference point, according to a predetermined criterion, to obtain reference points, determines a regression line of the reference points, and sets a slope and an intercept of the regression line as production index information of the production device.
