Utilization state settings

Each utilization reason is assigned a corresponding utilization state. In addition to the state's description and background color, the utilization state includes utilization default settings. These default settings can then be applied to the utilization reason when it is being added or edited.

• Utilization State

  Required. The unique name for the state.

• Color

  The state's background color in the user interface. A color is assigned by default, which can be changed. Enter the color's hex code or name.

• Priority

  A default setting for the utilization reason's priority, which is 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.

• 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.

• Cost As

  A default setting for the utilization reason’s Cost As setting, which is used to determine whether an event with this utilization reason is to be costed as fixed time, variable time, or neither.

• Failure

  A default setting for the utilization reason’s Failure flag. 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).

• Entity Enabled

  A default setting for the utilization reason’s Entity Enabled flag. If selected, specifies that any entity with this reason is enabled for production. If an entity is in a disabled state, then its production rate is not used in the calculation of the bottleneck line position.

• Maximum Duration

  A default setting for the utilization reason’s Maximum Duration value. 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

  A default setting for the utilization reason’s New Reason entry. 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. Note that this has the same effect as manually entering a new reason of Mechanic Assistance at the 5-minute mark. The new reason (Mechanic Assistance Required) starts at that time, and the Jam utilization event ends at that time. However, because utilization is only updated once a minute, the actual transition may be up to 59 seconds after the maximum duration of the original event (Jam in this example) was reached.

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

• Standard Time

  A default setting for the utilization reason’s Standard Time value. 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

  A default setting for the utilization reason’s Minimum Time value. 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

  A default setting for the utilization reason’s Maximum Time value. 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.

• Setup Time

  A default setting for the utilization reason’s Setup Time flag. If selected, specifies that an event with this utilization reason counts toward setup time.

• Teardown Time

  A default setting for the utilization reason’s Teardown Time flag. If selected, specifies that an event with this utilization reason counts toward teardown time.

• Category 1–4

  Default settings for the utilization reason’s category entries. Specifies a user-defined entry that describes a category.
