Optimizing Bicriteria Flow Shop Scheduling Problem By Simulated Annealing Algorithm

چکیده
We consider the flow shop scheduling problem with minimizing two criteria simultaneously: the total completion time (makespan) and the sum of tardiness of jobs. The problem is strongly NP-hard, since for each separate criteria the problem is strongly NP-hard. There is a number of heuristic algorithms to solve the flow shop problem with various single objectives, but usage of those heuristics to multi-criteria flow shop problems is rather limited. In this paper we propose a new idea of the use of simulated annealing method to solve certain multi-criteria problem. Especially, we define a new acceptance rules and the mechanism of moving the search in different regions of solution space by using so called drift. To illustrate quality of the proposed approach, we present results of the computational experiment provided on well known benchmarks.

A cloud-based simulated annealing algorithm for order acceptance problem with weighted tardiness penalties in permutation flow shop scheduling
Make-to-order is a production strategy in which manufacturing starts only after a customer's order is received; in other words, it is a pull-type supply chain operation since manufacturing is carried out as soon as the demand is confirmed. This paper studies the order acceptance problem with weighted tardiness penalties in permutation flow shop scheduling with MTO production strategy, the objec...
متن کاملSolving Re-entrant No-wait Flow Shop Scheduling Problem
In this study, we consider the production environment of no-wait reentrant flow shop with the objective of minimizing makespan of the jobs. In a reentrant flow shop, at least one job should visit at least one of the machines more than once. In a no-wait flowshop scheduling problem, when the process of a specific job begins on the first machine, it should constantly be processed without waiting ...

This paper studies the hybrid flow shop scheduling where the optimization criterion is the minimization of total tardiness.

Stochastic flexible flow shop scheduling problem (SFFSSP) is one the main focus of researchers due to the complexity arises from inherent uncertainties and also the difficulty of solving such NP-hard problems. Conventionally, in such problems each machine’s job process time may encounter uncertainty due to their relevant random behaviour. In order to examine such problems more realistically, fi...
