According to the make-to-order companies, when the due date determination process is not managed well, various problems are encountered. The order due date offered by the manufacturer in response to the customers' order request should both satisfy the customer and protect the manufacturer's profitability. In case the time difference between the due dates requested by the customers and the due dates suggested by the companies exceed the expectations and planning, various disputes and costs occur within the supply chain. In addition to the disputes caused by the late production of orders, there are various logistic costs which are not calculated for the products which are produced in stock and which are kept early in the demand date. Storage, handling and overdue amounts are some of these costs. Storage costs consist of warehouse rent and product insurance costs. The cost of handling covers the labor costs spent on loading and unloading, as well as the consumption of work machines. The overdue amount is calculated over the pre-paid capital expense for raw materials. In this study, these costs are expressed in detail by equations. The objective function for the proposed linear functions and logistics costs is then defined and the costs for the orders to be produced are listed according to the objective function. Furthermore, it is emphasized that both the due date and the price of the product can be negotiated between the manufacturer and the customer in order to reflect these costs to the product price or not to decrease the profitability of the enterprise. The proposed decision model offers a new and different approach because it contains logistics costs which are not considered in the studies of the due date. In this way, the proposed decision model in the study can be programmed in any software development environment and useful decision support systems can be developed to assist in making critical decisions for sales marketing units. In addition, a new way for the decision support systems, including logistics costs, is opened to researchers for subsequent studies.
