There are price erosions for components and final products, and more customers request product customization. In facing these challenges, the Assemble-To-Order (ATO) system has advantages over the traditional Make-To-Order (MTO) system. An MTO system stores final products while an ATO system stores components. In the above situation, how the contract manufacturer prestocks components with different lead times for final product assembling is an important issue. Furthermore, many contract manufacturers need to assemble different products with common components. Therefore, they also need to consider how to allocate common components to different products. We extend the multi-component, single-product ATO system in Hsu et al. (2006) to a two-component, two-product ATO system. We apply two different ordering and allocation policies for ordering and allocating the components based on the optimal procurement structure they construct. We set two problem types: one is the same-component-set problem, which the products are all assembled by the same component set. The only difference is the prices of products are different. The other is the different-component-set problem, which the products are assembled by different component sets with the same common component. We study how contract manufacturers prestock the components of various lead times under the different ordering and allocation policies. We use simulation to perform sensitive analysis. We discuss the effect of input parameters on the stock level and allocation decisions of contract manufacturers.
