Internal Tracking of Entity Production Rates

The estimated production rate for an entity is updated whenever any of the following events occur on the entity and the production rate has changed. When automatic determination of the bottleneck is being used, any time that an entity’s production rate is updated, a reevaluation of the line’s bottleneck is performed. The bottleneck information is displayed in the header area of every line page in MES Web Portal.

• A job is started on the entity and the new job's production rate is different than the entity’s previous production rate.

• A job is ended on the entity and the entity's projected production rate is different than that of the job that was ended. The projected production rate is determined by the next job that is expected to be run on that entity if one of the following events occurs:

  • A job starting on an upstream entity from that entity, where neither that entity nor any between it and the upstream entity where the job is being started are running any jobs.

  • A job ending on an upstream entity from that entity, where neither that entity nor any between it and the upstream entity where the job is being ended are running any jobs.

• A change in the production rate of a job running on the entity. Note that this can be a change in the job's production rate unit of measure, batch size, or the item being produced, as well as a change in the job’s production rate value itself. (In MES Client, the UOM, batch size, or item being produced cannot be changed while a job is running on the entity. When using the Stateless API, the item being produced cannot be changed while a job is running on the entity.)

• A change in the production rate of a job that is running on an upstream entity from the entity, where neither that entity nor any between it and the upstream entity where the job's production rate is being changed are running any jobs.

• A change in the default production rate of an entity if neither that entity nor any upstream entities from it are running any jobs. This would occur if one or more of the following parameters are changed for the entity: the standard item, the batch size, or the production unit of measure. See Configuring Entities.

• The entity is disabled by choosing a utilization reason for it that indicates that it is disabled (that is, a utilization reason for which the Entity Enabled flag is false) when the previously chosen utilization reason indicated that it was enabled. In this case, its production rate would go to 0.

• The entity is enabled by choosing a utilization reason for it that indicates that it is enabled (that is, a utilization reason for which the Entity Enabled flag is true) when the previously chosen utilization reason indicated that it was disabled. In this case, its production rate would probably change from 0 to some other value.
