Abstract
News editors obtained the following quote from the background information suppli ed by the inventors:“During supply chain planning, a supply chain plan may be g enerated by solving a supply chain planningproblem modeled as a single- or mult i-objective linear programming problem (LPP). For example, a supplychain planne r may model a master production problem as a multi-objective hierarchical LPP. T he supplychain planner may update and re-solve the supply chain planning proble m from time-to-time when changesoccur in the supply chain. However, even when t here are few changes to the supply chain and these changesare known, re-solving the supply chain planning problem may take as much time to solve as the previous supply chain planning problem. This inefficiency in re-solving a previously-so lved supply chain problemwhen there are only a few known changes to a supply ch ain is undesirable.”
