The Complexity of Safety Stock Placement in General-Network Supply Chains

Lesnaia, Ekaterina, Vasilescu, Iuliu, Graves, Stephen C. 01 1900 (has links)
We consider the optimization problem of safety stock placement in a supply chain, as formulated in [1]. We prove that this problem is NP-Hard for supply chains modeled as general acyclic networks. Thus, we do not expect to find a polynomial-time algorithm for safety stock placement for a general-network supply chain. / Singapore-MIT Alliance (SMA)

Optimizing Safety Stock Placement in General Network Supply Chains

Graves, Stephen C., Lesnaia, Ekaterina 01 1900 (has links)
In the paper, we minimize the holding cost of the safety stock held in a supply chain modeled as a general network. By our assumption, the demand is bounded by a concave function. This fact allows us to formulate the problem as a deterministic optimization. We minimize a concave function over a discrete polyhedron. The main goal of the paper is to describe an algorithm to solve the problem without assuming any particular structure of the underlying supply chain. The algorithm is a branch and bound algorithm. / Singapore-MIT Alliance (SMA)
