| Abstract | Sources of manufacturing firms´ competencies are expanding from product aspects to service aspects in the age of limitless global competition. Because of severe competitions and even level of technology, it is hard to gain differentiation from product aspects such as production cost or product quality. Owing to uncertain demand and dynamic market environments, service aspects such as flexibility and responsiveness are becoming distinctive competencies. Manufacturing firms´ flexibility and responsiveness can be evaluated based on their sales order processing by their customers. Therefore, manufacturing firms must focus on their sales order processing. However, most sales order processing related studies have focused on due-date assignment to minimize production cost and lead time estimation to meet due-dates. Those studies have targeted heavily on cost related objective functions. Furthermore, it is hard to increase flexibility and responsiveness because of high closely but loosely coupled connection cost and reliable real-time acquisition cost. Advances of Information Technology and Ubiquitous Computing Technology may make lower costs for connection and visibility and make these possible from a technical standpoint. This study considered changes in sales order management by advances of Information Technology and Ubiquitous Computing Technology. To increase flexibility, this study proposed flexible and reliable due-date assignment method and conducted simulation experiments to compare with general due-date assignment methods with some performance indices. To enhance responsiveness, due-date re-negotiation process and business integration model are proposed in this study. The proposed sales order management could help manufacturing firms to assign flexible and reliable due-date in uncertain demand and dynamic market environments. In some circumstances beyond control, a manufacturing firm is possible to relieve the shock and minimize customer´s damage through the proposed due-date re-negotiation method. |
