Abstract
Abstract A decision-making method suitable for production planning in an uncertain demand environment. To this end, the method comprises combining an implosion technology with a scenario-based analysis, thus manifesting, a sui generis capability which preserves the advantages and benefits of each of its subsumed aspects.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
A program storage readable by a machine, tangibly embodying a program of instructions executable by a machine to perform method steps for production planning in an uncertain demand environment, said method steps comprising: a) inputting a plurality of demand scenarios over a timing horizon and a probability associated with each of said demand scenario which represent uncertainties in a demand environment; b) employing a scenario-based analysis including the steps of performing multiple optimization runs against different demand scenarios; c) combining an implosion technology with the scenario-based analysis for generating for any one individual demand scenario, a deterministic solution which is optimal for the particular demand scenario; and, d) generating an output comprising a payoff table that includes said solution for each demand scenario, each said solution being optimized in accordance with a selected performance measure.
Claim 2
Dependent Claim
135 words
