Production record data analyzer

Abstract

According to the method, a startup sequence rule model conforming to an actual startup sequence rule of a production site is constructed. Event data of the production performance data includes information of an event in which a next job to be executed is selected from the jobs to be executed for each process.Each dispatching rule model in each dispatching rule model set is configured to anticipatea job to be selected next from waiting jobs in an event in a process associated with the dispatching rule model set. One or more processors are configured to: generate anticipation results of a selected event with the plurality of dispatching rule models associated with the process; determine reliability of the selected event based on whether each of the jobs indicated in the anticipation resultsis the same as the job actually selected in the selected event shown in the production record data in each of the plurality of processes; and determine whether to include the selected event to training data for generating a new dispatching rule model based on the reliability in each of the plurality of processes.

Description

technical field [0001] The present invention relates to a production performance data analysis device for analyzing production performance data at a production site such as a factory. Background technique [0002] When formulating a production plan at a production site such as a factory, it is generally a method of predicting future production under arbitrary conditions and deriving conditions that maximize evaluation indicators such as future throughput and delivery date compliance rate. Production simulation is a typical method of production forecasting, but in order to realize high-precision production forecasting, it is necessary to model the start-up sequence rules that match the actual conditions of the production site. [0003] The start sequence rule refers to the rule for determining the next job to be executed from the group of jobs waiting to be executed in a certain process. Especially in the case where a person decides the start sequence of a production site, t...

Problems solved by technology

[0004] However, the starting sequence rule model determined by the above method does not necessarily conform to the actual situation of the production site

In the case where the starting sequence rule model deviates from the actual situation, the prediction accuracy of the production simulation decreases, so the production plan formulated according to the prediction lacks the possibility of realization and suitability
