Utilization reason properties

Description

The name of the utilization reason. The reason description describes the utilization condition of an entity and identifies the utilization reason in the data records, so it must be unique within its reason group.

Utilization State

Select an existing utilization state or click Browse button to create a new utilization state. The utilization state indicates the state that is appropriate for this utilization reason. For more information on creating a new utilization state, see Create a utilization state.

Apply Defaults

Click this button to apply the default values specified for the selected utilization state to the utilization reason's properties.

Priority for Line Utilization

Used to determine the reason for a line that has two or more bottleneck entities with differing reasons. The reason with the highest-numbered priority value is used as the line’s utilization reason.

The default is 1. A value must be entered, and 0 is not allowed. If 0 entered, the value defaults to 1.

Reason Enables Entity

If selected, specifies that any entity with this reason is enabled for production.

Failure

If selected, specifies that any time that the entity spends in the utilization reason is considered failure time. Failure time is used in the calculation of Mean Time Between Failures (MTBF) and Mean Time to Repair (MTTR).

OEE Use

• Runtime

  If selected, specifies that an event with this utilization reason counts toward runtime. Runtime events contribute to the calculation of Availability and Performance.

• Downtime

  If selected, specifies that an event with this utilization reason counts toward downtime. Downtime events contribute to the calculation of Availability.

• Neither

  If selected, specifies that an event with this utilization reason does not count toward runtime or downtime. Therefore, this utilization reason time is excluded from the calculation of OEE.

Maximum Duration

Specifies the maximum duration, in seconds, that is used with setting a Severe flag or with the New Reason parameter.

• If the New Reason functionality is not being used (that is, there is no entry in the New Reason column) and the maximum duration is exceeded, the reason is marked as being Severe and the event is considered to be in a severe condition. The Severe flag is typically used with downtime events.

• If the New Reason functionality is being used (that is, there is an entry in the New Reason column) and the maximum duration is exceeded, the utilization reason for the entity is changed to the new reason specified in the New Reason column.

  A value of 0 is not allowed. If 0 entered, the value defaults to 1.

  If Maximum Duration is not being used, leave this field blank, which disables the feature.

New Reason

The utilization reason that this reason should change to when the maximum duration is exceeded. For example, if a Jam condition exceeds a maximum duration of 5 minutes, then the entity would change to the new reason Mechanic Assistance Required.

If you are using the Maximum Duration setting to set a Severe flag, then leave this setting blank.

This setting is not available unless a value is entered for Maximum Duration.

Duration

• Standard Time

  The standard amount of time, in minutes, that an entity is expected to be in this utilization reason. Entered values are rounded to two decimal places.

• Minimum Time

  The minimum amount of time, in minutes, that an entity is expected to be in this utilization reason. Entered values are rounded to two decimal places.

• Maximum Time

  The maximum amount of time, in minutes, that an entity is expected to be in this utilization reason. Entered values are rounded to two decimal places.

Cost As

• Fixed

  If selected, specifies that an event with this utilization reason is costed as fixed time.

• Variable

  If selected, specifies that an event with this utilization reason is costed as variable time.

• Neither

  If selected, specifies that an event with this utilization reason is not costed as fixed time or variable time.

Scheduling Use

• Setup Time

  If selected, specifies that an event with this utilization reason counts toward setup time.

• Teardown Time

  If selected, specifies that an event with this utilization reason counts toward teardown time.

Category 1–4

Specify user-defined entries that describe categories.
