چکیده
This paper studies a combinatorial optimization problem which is obtained by combining the two-machine flow shop scheduling problem and the shortest path problem. The objective of the obtained problem is to select a subset of jobs constitutes a feasible solution to the shortest path problem, and to execute the selected jobs on two-machine flow shop to minimize the makespan. We argue that this problem is NPhard, and propose two approximation algorithms with constant factor guarantee.

Net 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 کاملImproved teaching–learning-based and JAYA optimization algorithms for solving flexible flow shop scheduling problems
Flexible flow shop (or a hybrid flow shop) scheduling problem is an extension of classical flow shop scheduling problem. In a simple flow shop configuration, a job having ‘g’ operations is performed on ‘g’ operation centres (stages) with each stage having only one machine. If any stage contains more than one machine for providing alternate processing facility, then the problem...

This paper presents a mathematical model for a flow shop scheduling problem consisting of m machine and n jobs with fuzzy processing times that can be estimated as independent stochastic or fuzzy numbers. In the traditional flow shop scheduling problem, the typical objective is to minimize the makespan). However,, two significant criteria for each schedule in stochastic models are: expectable m...
متن کاملA New Approach Generating Robust and Stable Schedules in m-Machine Flow Shop Scheduling Problems: A Case Study
This paper considers a scheduling problem with uncertain processing times and machine breakdowns in industriall/office workplaces and solves it via a novel robust optimization method. In the traditional robust optimization, the solution robustness is maintained only for a specific set of scenarios, which may worsen the situation for new scenarios. Thus, a two-stage predictive algorithm is prop...
