Understanding Constraint-Based Planning
When running unconstrained plan, The MRP generates a supply plan based on the supposed infinite availability of materials and resources.
When running a constrained plan, material and resources availability is limited, you can choose to enforce capacity constraints or to enforce demand due dates.
- Enforce capacity constraints: Your plan will not violate supplier, manufacturing and transportation capacity. It will not result in material shortage but it may violate demand due dates to respect capacity constraints.
- Enforce demand due dates: This plan may violate capacity constraints (e.g. overload resource and supplier capacity) to respect demand due dates.
