Economic lot scheduling problem with imperfect production processes

Journal of the Operational Research Society, 2000
Summary: In this paper, we model the effects of imperfect production processes on the economic lot scheduling problem (ELSP). It is assumed that the production facility starts in the in-control state producing items of high or perfect quality. However the facility may deteriorate with time and shifts at a random time to an out of control state and ...

Heuristic Scheduling of Batch Production Processes Based on Petri Nets and Iterated Greedy Algorithms

IEEE Transactions on Automation Science and Engineering, 2022
Wire rod and bar rolling is an important batch production process in steel production systems. A scheduling problem originated from this process is studied in this work by considering the constraints on sequence-dependent family setup time and release ...

An approach to process production reactive scheduling

ISA Transactions, 2004
Process manufacturing has some characteristics that make it different from other types of industry. In practice, there are many examples of process industrial settings where production resources are shared and there is no intermediate storage between two processing units.

Dynamic Production Scheduling for a Process Industry

Operations Research, 1994
Capacity-oriented production scheduling can be described as the assignment of competing products to several single level, capacitated production lines over a given planning horizon. This study was initially motivated by the production planning of various types of tiles by a tile manufacturing company.

Production transportation scheduling for process industry

2010 Second International Conference on Computational Intelligence and Natural Computing, 2010
Production transportation scheduling problem with constraints is common in process industry. But it is a NP-hard problem. In this paper, the production transportation scheduling problem between a plant that produces intermediate products and a finishing plant which processes the intermediate products in finished goods is studied.

A Scheduling Process Applied to Newspaper Production

2006 International Conference on Service Systems and Service Management, 2006
This paper proposes a support system which helps in deciding the allocation of resources for newspaper production. The system is structured starting from a covering model with the objective of determining the best sequencing of n tasks in m machines, obeying the schedule of delivery of the tasks.

Scheduling a Single-Product Reentrant Process with Uniform Processing Times [PDF]

Industrial & Engineering Chemistry Research, 2000
Most semiconductor manufacturing involves multiple stages of batch/semicontinuous physicochemical operations. Scheduling of such plants becomes complex because of a high degree of reentrancy in their process flows, as different lots/batches as well as different tasks of the same lot compete for time on the various processing units at each stage ...

Production Scheduling in Food Processing Plants

Transactions of the ASAE, 1985
IN multi-product processing plants, when product demand exceeds the production capacity, the production planning and scheduling function becomes very important anc exceedingly difficult. The impact of poor scheduling can be significant in any plant. Therefore plant managers are forced to use modern (computer-aided) production scheduling techniques to ...
