As one can see from Table 2, the ATO production process can be used to save inventory carrying costs (the sum of opportunity cost, shrinkage, insurance and taxes, total obsolescence cost) by an average work in process (WIP) reduction of at least 68.6% (scenario SC 2) and up to 78.6% (scenario SC 7). As shown in Section 2, the relocation of the CODP is possible only if additional resources are used (e.g., employees and trucks). It is necessary to fulfill the customer requirement that is represented by delivery performance quoting the percentage of orders fulfilled within 5
days. The b-service level (fill rate) can be used as lower bound for the delivery performance.
