Main > frePPLe Tutorial > Constraints: Putting it all together...
In the previous sections we explored lead time, material and capacity constraints seperately on a minimalistic model. In reality these constraints all appear simultaneously, and it is when they interact that a planning system like frePPLe brings real value to your business.
Some examples:
- Coordinate the purchasing of components
If the supply of a certain component is late or short, the requirements of other components that go in the same subassembly will also be late or short. The just-in-time purchasing keeps the inventory low. - Coordinate material and capacity requirements
There is no need to procure raw material early if there is no capacity to process it in time. - Search alternate materials and capacity
If a material or resource is unavailable, frePPLe will search all alternates to maximize the on-time delivery of the demand. - Prioritization of demand
FrePPLe sorts the demands in order of priority and will assign capacity and material to the most important demands first. Lower priority demands will be late or short, while the high priority demands are planned on time.
