Abstract
A system and method are disclosed for an inventory planner that generates an inventory policy using any form of demand distributions, non-linear cost functions and/or multiple target measures of service levels, while taking into account a supply order lead time, such as, for example, a static or stochastic supply order lead time. The inventory policy generated by the inventory planner comprises an optimal and reproducible solution to one or more supply chain planning problems.
Claims18
A system, comprising:
- a computer comprising a processor and a memory, the computer configured to:
- generate one or more transitional matrices comprising a supply leadtime;
- generate one or more reward matrices comprising cost components;
- model a supply chain planning problem as a Markov decision process (MDP) based, at least in part, on the generated one or more transitional matrices and the generated one or more reward matrices;
- solve the MDP, by:
- determining, from solution values where an order quantity is zero, a resulting state after an order action is applied;
- generating from the solution values, indices comprising a minimal state and a target state;
- generate an inventory policy based, at least in part, on the solution of the modeled supply chain planning problem wherein the computer adjusts inventory levels of at least one stocking point and adjusts sourcing of one or more supply chain entities, based at least in part, on the inventory policy;
- and
- in response to and based, at least in part, on the inventory policy, cause the one or more supply chain entities to ship one or more items.
