Hi Arun,
APO Supply Network Planning (SNP) integrates purchasing, manufacturing, distribution, and transportation so that comprehensive tactical planning and sourcing decisions can be simulated and implemented on the basis of a single, global consistent model. Supply Network Planning uses advanced optimization techniques, based on constraints and penalties, to plan product flow along the supply chain. The result is optimal purchasing, production, and distribution decisions; reduced order fulfillment times and inventory levels; and improved customer service.
Starting from a demand plan, Supply Network Planning determines a permissible short- to medium-term plan for fulfilling the estimated sales volumes. This plan covers both the quantities that must be transported between two locations (for example, distribution center to customer or production plant to distribution center), and the quantities to be produced and procured. When making a recommendation, Supply Network Planning compares all logistical activities to the available capacity.
Supply Network Planning Run:
You perform the planning run once you have chosen the method and carried out the prerequisite steps.
The result of a Supply Network Planning run using the heuristic, the optimizer, supply and demand propagation, or Capable-to-Match is a medium-term production and distribution plan.
Interactive Planning:
After the SNP run, you review the plan in the interactive planning desktop. If you run heuristic-based planning, you can also level capacities from the interactive planning table.
SNP Heuristics: repair-based planning
Quota arrangements
Capacity leveling
And also,
HEURISTC RUN
Heuristic groups all existing demands for a given product a location into a total demand for the period.
When you perform SNP run using heuristic, ctm, and optimizer you obtain a medium term production and distribution plan.
Final SNP plan consists of purchase requisitions, SNP stock transfer orders and snp planned orders.
Final SNP plan is released back to DP to compare unconstrained demand plan with the SNP plan.
Heuristic is Quantity based, cross plant planning, mrp 2 concept.
Heuristic performs following activities
u2022 Plan supply to meet demand
u2022 Model the entire supply network
u2022 Integrate purchasing, production and distribution in consistent model
u2022 Synchronize the activities and plan the follow of material through the entire supply chain.
Factors to be considered during heuristic run
u2022 Transportation lanes
u2022 Quota arrangements
u2022 Lot sizing
u2022 Calendar
u2022 Safety stock
u2022 ppm
Heuristic Processing
Data is read from the live cache
Net requirements are calculated
Lot sizing is considered
Procurement type is checked
Receipts are created
Resource load is calculated
Heuristic Run Models.
Location u2013 Selected products are planned here.
Networku2014Selected products are planned for all locations
Multilevelu2014selected products are planned with all components and for all locations
Heuristic will not give a feasible plan as it will not consider capacities, to generate a feasible plan you do capacity leveling.
I hope this is very useful for you.
If you have any queries pls revert me.
