The paper addresses the problem of scheduling production orders (jobs). First an approach based on simulated annealing and Hopfield nets is described. Since performance was unsatisfactory for real-world applications, we changed problem representation and tuned the scheduling method, dropping features of the Hopfield net and retaining simulated annealing. Both computing time and solution quality...

An important production programming problem arises in paper industries coupling multiple machine scheduling with cutting stocks. Concerning machine scheduling: how can the production of the quantity of large rolls of paper of different types be determined. These rolls are cut to meet demand of items. Scheduling that minimizes setups and production costs may produce rolls which may increase wast...

Hoist scheduling is an important element for productivity maximization in multi-stage material handling processes, especially in electroplating system. However, the productivity of a multi-stage process not only depends on the hoist schedule, but also substantially relies on the production line arrangement, i.e., the design for spatial allocations of various processing units. In this paper, an ...

PRODUCTION MANAGEMENT IS crucial for achieving the timely and costeffective execution of industrial production processes. In recent years, interest has increased in the use of artificial intelligence technologies for production planning and scheduling.1,2 However, scheduling research typically has been theoretical, has had a narrow focus, and has not covered adaptation to unforeseen events (see...

Process scheduling is a classical problem in the field of production planning and control; in particular, effective job shop scheduling remains an essential component in today’s highly dynamic and agile production environment. This paper presents unified framework for solving generic job shop scheduling problems based on the formulation of a job shop into three main classes of problem, namely, ...

Significant number of producers and manufacturers are realizing substantial financial environmental benefits from sustainable/ greener business practices. Sustainable production manufacturing the creation manufactured products through economically-sound processes that minimize negative impacts while conserving energy natural resources. also enhances employee, community, product safety. The aim ...

The objective of multi-site scheduling is to support the scheduling activities of a global scheduler and schedulers in distributed production plants in a cooperative way. A global schedule generated on a global level must be translated into detailed schedules as part of the local scheduling process. In case of disturbance, feedback between the local and global levels is essential. Global level ...

Lot streaming is the process of splitting a production lot into sublots, and then scheduling the sublots in overlapping fashion on the machines, in order to improve the overall performance of the production system. Simulation-based and industry-based reports have con"rmed that substantial bene"ts are possible via lot streaming. In this paper, we present, for the "rst time, analytical results pe...
