Plan Based on Workday Patterns in a Resource Calendar

Manufacturing organizations use calendars most commonly applicable for a plant and assign workday patterns that are applicable to specific resources in that plant.

In a constrained supply plan, you can configure a plan option parameter to consider more granular workday patterns in a resource shift instead of using the manufacturing calendar.

Use the EnableResCalendar=true parameter to instruct the planning process to honor the resource availability of the first and last resource in a work definition. The suggested start date and suggested dock date of a make supply will then fall on days when respective resources are available. This process enables more accurate planning calculations by considering the actual resource availability in a constrained supply plan.

Perform these steps to configure the Setting for Multithread parameter to enable the resource calendar.

Note: Before you can set the multithread parameter, you must first opt in to the Plan Based on Workday Patterns in a Resource Calendar feature.
  1. Open a constrained supply plan and navigate to the Plan Options page, Supply tab, General subtab, and click the Select Advanced Options button.

  2. In the Supply: Advanced Options dialog box, navigate to the Optimization Parameters tab.

  3. In the Setting for Multithread text box, enter EnableResCalendar=true.

    If there is another value set for this parameter, add the EnableResCalendar=true value at the end, separated by a comma.

The following provides some insight into how supply planning plans based on workday patterns in a resource calendar when the Setting for Multithread parameter is set to EnableResCalendar=true.

  • The planning process honors only the shift calendar assigned to the first and last resource of a work definition.

  • The planning process determines the first resource as the first scheduled resource associated with the first operation in the work definition.

    The planning process determines the last resource as the last scheduled resource associated with the last operation of the work definition.

  • The suggested start date of a make supply will fall on a working day of the resource shift calendar associated with the first resource.

    The suggested dock date falls on a working day of the resource shift calendar associated with the last resource of the work definition.

  • While planning, if the suggested start date falls on a nonworking day for a resource, then the planning process starts the order early by moving the start date into a working date.

    If the suggested dock date falls on a nonworking day of the last resource, then the planning process will prebuild the order by moving the dock date to an earlier working day of the resource.

  • The planning process respects processing lead times. If the planning process doesn't find a working day in an earlier bucket, the suggested start date or dock date can fall on a nonworking day of a resource shift calendar.

  • If supply planning selects alternate resources during the planning process, then the start date or dock date for the make supply falls on a valid workday of the shift calendar for the alternate resource.

  • If the Capacity Constrained Resources plan options parameter is All resources, then resource shift calendar is considered for all resources that are assigned as first and last resource of work definitions as described above.

    If Bottleneck resources only is selected, then resource shift calendar is considered only for bottleneck resources based on criteria as described above.

  • The resource requirements of intermediate resources in a work definition can fall on days when a resource isn't available but is a working day in the organization's manufacturing calendar.
