Production scheduling in preemptive and simultaneous processing

Computers in Industry, 1992
Abstract The paper explores production scheduling problems in which jobs with deadlines are processed preemptively and/or simultaneously on identical machines. Based on the concepts of reservations and surpluses, it is checked whether a given set of n jobs is feasible.

The specifics of production scheduling in process industries

2002 IEEE International Conference on Industrial Technology, 2002. IEEE ICIT '02., 2003
Process manufacturing has some characteristics that makes it different from other types of industry. These specifics are reflected in the design of a process factory management system. This paper stresses some features of process manufacturing that have to be taken into account during the implementation of a production scheduling system.

Planning and Scheduling Models for EMAS Productive Process

Applied Mechanics and Materials, 2013
This paper addresses the problems of EMAS (an engineer material to arresting aircraft on the ground) production operation that the intensity of each product was uneven and cellular concrete was not completely crumple.In order to solve the problem the development of a nonlinear planning model for EMAS production was presented.

Scheduling of Production with Alternative Process Plans

2014
This chapter deals with a scheduling problem with alternative process plans that was motivated by a production of wire harnesses where certain parts can be processed manually or automatically by different types of machines. Only a subset of all the given activities will form the solution, so the decision whether the activity will appear in the final ...

Statecharts model and heuristic scheduling of a production process

2011 15th IEEE International Conference on Intelligent Engineering Systems, 2011
Modern factories often employ elaborate manufacturing information systems involving a computer network and various databases. In practice, it often happens that soon after a plan or schedule has been generated, an unexpected event happens that forces the decision-maker to make changes.

Interaction of the Decision Maker in the Process of Production Scheduling

Advanced Materials Research, 2014
In the paper the role of the decision maker in the process of production scheduling is discussed. A general procedure specifying the activities carried out within the framework of particular steps of scheduling is shown. The scope of the interactions of the decision maker in the scheduling process under conditions of real time system is commented.

Common cycle scheduling in a multistage production process

Engineering Costs and Production Economics, 1990
Abstract The conventional approach to the common cycle problem assumes a single production stage and takes into account only the setup costs and the carrying costs of finished inventories. This approach is limited to a single stage production process because the carrying costs of in-process inventories which are inherent in any multistage production ...

Scheduling approach for concurrent product development processes

Computers in Industry, 2001
Abstract A heuristic scheduling approach is proposed for the concurrent product development processes, in which some crucial parameters are determined using the genetic algorithm (GA). Scheduling concurrent activities is of great significance to shorten development lead-time and minimize costs, since it can eliminate unnecessary redesign periods and ...
