Abstract: A supply chain management system is configured to create supply chain network information including information on a directed graph representing a multi-tiered supply chain network including tiers upstream and downstream of the target enterprise, acquire risk information on the multi-tiered supply chain network, detect, in the directed graph, a risk occurrence node influenced by a risk and a node of the target enterprise influenced by a defect of product supply at the risk occurrence node, search for a substituting node candidate for the risk occurrence node in a node group including a node of an enterprise outside the directed graph based on an item of the risk occurrence node, and present information on a change plan of the multi-tiered supply chain network obtained by adding the substituting node candidate to the directed graph.

Abstract: According to one embodiment, a scheduling unit determines a derivation start date and time and derivation end date and time for each supply chain model on the basis of a time required for deriving a restriction relaxing optimum operations combination and a relaxation proposing timing, a schedule execution unit starts deriving a restriction relaxing optimum operations combination for a target supply chain model on the basis of the derivation start date and time determined by the scheduling unit, and a restriction relaxing optimum operations combination-generating unit generates an operations combination of update timings and methods for plans or instructions assuming that a restriction is relaxed.
