Decomposition-based Makespan Minimization in Job Shops

This paper proposes a decomposition-based heuristic approach to minimizing the makespan of job shops. In general, decomposition methods first divide the whole problem into several sub-problems, solve them and then combine sub-schedules to obtain a good feasible schedule. Although it may be reasonable to minimize the makespan of each sub-problem, its optimality will be lost when combining sub-sc...

Benders Decomposition for Mixed- Integer Hydrothermal Problems by Lagrangean Relaxation

Decomposition models with integer variables usually decompose into a master problem that comprises all the integer variables and subproblems, which evaluate the remaining variables. Subproblems with integer variables introduce additional difficulties and require the use of nonlinear duality theory. In this paper we address the solution of a mixed integer hydrothermal coordination problem combin...

Makespan Minimization with Machine Availability Constraints

We investigate the problems of scheduling n jobs tom = m1+ m2 identical machines where m1 machines are always available, m2 machines have some specified unavailable intervals.The objective is tominimize the makespan. We assume that if a job is interrupted by the unavailable interval, it can be resumed after the machine becomes available. We show that if at least one machine is always available,...

Solving railway line planning problems using a decomposition algorithm

The passenger line planning is a process of strategic long-term decision-making problem in the field of railway passenger planning. A line is a route between starting point and destination with certain stops, which has a certain frequency of train schedule. A new solution based on decomposition algorithm has been proposed in this paper, which is defined in a master problem and two sub problems....
