Flow-shop Problems: A Heuristic Search Algorithm
نویسنده
چکیده
This article presents an intelligent heuristic search algorithm (IHSA*) for solving flow-shop problems with two or three machines and an arbitrary number of jobs. Following its initial development the algorithm has been modified in two different ways in order to reduce backtracking and to improve its performance. The first modification concerns the choice of the best heuristic function to use, and the second modification concerns the way in which heuristic estimates at nodes on the search path are determined as the search progresses. Experimental evidence of the improved performance of the algorithm as a result of each of these modifications is presented.

Heuristic approach to solve hybrid flow shop scheduling problem with unrelated parallel machines
In hybrid flow shop scheduling problem (HFS) with unrelated parallel machines, a set of n jobs are processed on k machines. A mixed integer linear programming (MILP) model for the HFS scheduling problems with unrelated parallel machines has been proposed to minimize the maximum completion time (makespan). Since the problem is shown to be NP-complete, it is necessary to use heuristic methods to ...

متن کاملNet Present Value of Cash Flows in Single Machine and Flow Shop Scheduling Problems
While a great portion of the scheduling literature focuses on time-based criteria, the most important goal of management is maximizing the profitability of the firm. In this paper, the net preset value criterion is studied taking account of linear time-dependent cash flows in single machine and flow shop scheduling problems. First, a heuristic method is presented for the single machine scheduli...

متن کاملFlow Shop Scheduling Problem with Missing Operations: Genetic Algorithm and Tabu Search
Flow shop scheduling problem with missing operations is studied in this paper. Missing operations assumption refers to the fact that at least one job does not visit one machine in the production process. A mixed-binary integer programming model has been presented for this problem to minimize the makespan. The genetic algorithm (GA) and tabu search (TS) are used to deal with the optimization...
متن کاملMinimizing Makespan with Start Time Dependent Jobs in a Two Machine Flow Shop
[if gte mso 9]> The purpose of this paper is to consider the problem of scheduling a set of start time-dependent jobs in a two-machine flow shop, in which the actual processing times of jobs increase linearly according to their starting time. The objective of this problem is to minimize the makespan. The problem is known to be NP-hardness[ah1] ; therefore, there is no polynomial-time algorithm...
