Abstract


The many varieties of small batch production mode is a mode of production in response to market demand for diversity and fast requirements, and production of one of the way to change the trend. Orders on time fast delivery is an important measure of manufacturing enterprise service level standards. Reasonable order scheduling to improve the level of service of the order delivery time is an effective means to-order manufacturing enterprises to enhance their level of production management. The order scheduling constraints of limited resources to achieve the target of orders on time fast delivery, through the development of reasonable production planning task orders. Research a variety of small quantities of MTO dynamic scheduling problem subject background, for example. Analyzed on the basis of scheduling processes orders for production and orders in the subject background, the proposed Order Scheduling Problems to solve a variety of small quantities to order manufacturing orders production management-oriented key link. First establish the framework of a new dynamic order scheduling system, scheduling in order to establish a new order production management processes as the core. Orders followed for the subject background characteristics of the production system with parallel production constraints and orders into a tree, task decomposition, integer programming methods Order Scheduling process constraint is the main objective of building a production capacity into a tree to deliver orders on time Order Scheduling mathematical model. Order Scheduling mathematical model based on the relaxation of the model assumptions, from the long task orders, continuous production, inventory order packet and production systems to the four aspects of the the Order Scheduling mathematical model optimized and improved. The manufacturing process is a dynamic process, it is proposed in this paper based on the combination of dynamic event-driven and periodic driving dynamic order scheduling, order scheduling model can be applied to the actual production system. By scrolling the window scheduling and production model of the amendment of the Order Scheduling Order Scheduling periodic driving and dynamic event-driven dynamic process. Finally, the subject background numerical example, and scheduling to analyze the results, this paper, the dynamic scheduling method to meet a variety of small quantities for the order scheduling of manufacturing orders demand. In this paper, the dynamic scheduling An example shows that demand-oriented orders production orders to meet the more varieties of small batch production scheduling and order management, order to shorten the production cycle, improve the level of on-time delivery of orders.
