Specifications for Production Metrics Reporting and Alarming

For production metrics, specifications provide targets and limits for reporting purposes, and to trigger alarms. Limits are used only for alarming. For each of the following, per product, create target specifications and, if you wish to configure alarming, lower and upper reject limits. You then choose these specifications while configuring Production Metrics.

For detailed information on creating specifications, see Building a Plant-level Recipe or Product Specification, found under Product Management in the Plant Applications Help Contents.

Availability Rate

• Targeted downtime rate as a percentage. Enter this as an integer (e.g., 10.5 = 10.5%).

This specification is the percentage of Unplanned Downtime that is acceptable.

• Used in Production Metrics in the Downtime tab as the Availability Downtime Percent Specification .

Efficiency Rate

• Targeted OEE rate as a percentage. Enter this as an integer (e.g., 90.5 = 90.5%).

• Used in Production Metrics in the Efficiency tab as the Efficiency Percent Specification.

Production Rate

• The Production Rate specification is used by Plant Applications in OEE calculations. Production Rate is the design speed for each product that can run on each piece of equipment. Assigned to a specification variable, this number is the target (ideal) amount or number of units to produce. In Production Metrics, you choose the time units (per day, hour, minute, or second) that actually determines the rate. This specification must be configured in order for Plant Applications to calculate OEE.

•  Used in Production Metrics in the Production tab as the Production Rate Specification, in conjunction with Production Rate Time Units.

Waste Rate

• Targeted quality rate as a percentage. Enter this as an integer (e.g., 10 = 10%).

This specification is the percentage of waste that is acceptable.

• Used in Production Metrics in the Waste tab as the Waste Rate Specification.
