The impact of component commonality in an assemble-to-order environment under supply and demand uncertainty

A material requirements planning simulator with a two-level bill-of-material is used to study the impact of introducing component commonality into an assemble-to-order environment when demand is subject to random variations, and component procurement orders experience random delays. By using simulated data, our ANOVA results show that component commonality significantly interacts with existence of demand and supply chain uncertainties, and benefits of component commonality are most pronounced when both uncertainties exist.Component commonality Lead-time uncertainty Demand uncertainty Assemble-to-order environment
