Utilization reason settings

The following utilization reason configuration settings are available:

• Description

  The unique description for the reason.

• Utilization State

  The state with which the utilization reason is associated.

• 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.

• Is entity enabled when this reason applies?

  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).

• 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.

• 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.

• 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.

• OEE Use: Downtime

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

• OEE Use: 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.

• Scheduling Use: Setup Time

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

• Scheduling Use: Teardown Time

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

• Categorization: Category 1–4

  Specifies a user-defined entry that describes a category.

  Note: These category entries are currently not integrated with MES Category definitions.

• Cost As: Fixed Time

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

• Cost As: Variable Time

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

• Cost As: Neither

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