In many production factories, a production for make-to-order is adopted because of various customer's needs and short lifetime of products. Moreover, jobs for make-to-order are generally given to be short due-date so that lead time of these jobs needs be reduced to conform to the due-date. In order to reduce lead-time of orders, some factories have introduced a function which makes jobs for estimated production to be assigned jobs which are ordered with short due-date. In this paper, a production system including the function is proposed and the performance of the functions is evaluated with regard to reduction of lead-time of receipt order.
