Analyze Late Demands Due to Capacity Constraints

Understand the root cause of late demands in plans when you’re enforcing capacity constraints by analyzing how early a supply can be built considering both lead time and capacity constraints on resources or at suppliers. The existing Earliest Start Date and Slack attributes will be calculated considering both capacity and lead time constraints. Previously, only lead times constraints were considered in calculating these attributes. This refinement to the calculations can help you understand the root causes behind late demand in a plan when you’re enforcing capacity constraints.

Example of how you can analyze a demand that's late due to supplies using resources and suppliers that are capacity constrained:

Steps to Enable

Use the Opt In UI to enable this feature. For instructions, refer to the Optional Uptake of New Features section of this document.

Offering: Supply Chain Planning

If you want to use the Analyze Late Demands Due to Capacity Constraints feature, then you must opt in to its parent feature: Constraint-Based Planning and Plan Considering Manufacturing and Supplier Capacity Constraints as Inviolable Constraints If you’ve already opted in to these features, then you don’t have to opt in again.

Perform the following steps to compute the Earliest Start Date and Slack attributes based on capacity and lead time constraints for analyzing demands late due to constraints:

  1. Create a constraint-based plan.
  1. In the Constraints and Decisions Rule subtab in the Supply tab enable Enforce resource capacity constraints for enforcing resource capacity constraints as inviolable constraints.
  1. Enable the Enforce supplier capacity constraints for enforcing supplier capacity constraints as inviolable constraints plan option.
  1. Save and run plan.

You can now analyze lateness for demands due to supplies with resource and suppliers having capacity constraints enforced as inviolable constraints.

Tips And Considerations

  • Earliest start dates for supplies are computed based on capacity and lead time constraints.
  • Slack displayed in the Late Demand Analysis user interfaced is also computed based on capacity and lead time constraints.
  • You can now perform the GET operation for supplies from your plans of the Supply Plan and Demand and Supply Plan plan types for the Earliest Start Date and Latest Start Date attributes.
