Understand production rates

The expected production rate for a given entity is the estimated production rate for the job running on the entity. This is also referred to as the standard production rate, as it is the rate that is set by the time standard for the job. The expected rate can default to the standard rate defined for the entity if a rate is not defined for the job.

The actual production rate is the rate derived by dividing the total production (good and reject) by the amount of time that the entity was in a running state for the job.

Line properties used to determine production rates

The following line properties must be defined to support the determination of the line’s production rates.

• Standard Item — The standard item that is being produced on the line.

• Batch Size — The standard batch size used when producing items on the line. The default is 1.

• Production Unit of Measure —The standard production rate unit of measure for items produced on the line. The default is hours/batch.

Determine a line's performance and production amounts

A line’s performance amount is the amount of production (good and rejects) at the line’s bottleneck entity (see Understand bottleneck entities). If the line’s bottleneck is a set of parallel entities, the performance amount for the line will be the sum of the performance amounts of the parallel entities. Rejects from entities upstream from the bottleneck entity/entities are not included in the performance amount.

A line’s production amount is the amount of production (good and rejects) to be reported to resource planning systems, such as an enterprise resource planning (ERP) system. It is based on the amount of production at the entity defined as the line’s production source, which is usually the last entity in the line. If there are other entities at the same line position as the entity that is defined as the production source, the production amount will be the sum of the production of all entities at that line position.
