A 2-approximation algorithm for interval data minmax regret sequencing problems with the total flow time criterion
نویسندگان
چکیده
In this paper we discuss a minmax regret version of the single machine scheduling problem with the total flow time criterion. Uncertain processing times are modeled by closed intervals. We show that if the deterministic problem is polynomially solvable, then its minmax regret version is approximable within 2.

Solution algorithms for unrelated machines minmax regret scheduling problem with interval processing times and the total flow time criterion
An uncertain version of the task scheduling problem on unrelated machines to minimize the total flow time is considered. It is assumed that processing times are not known a priori, but they belong to intervals of known bounds. The absolute regret is applied to evaluate the uncertainty, and minmax regret task scheduling problem is solved. A simple 2-approximate middle intervals time efficient al...
متن کاملHeuristic algorithms for the minmax regret flow-shop problem with interval processing times
An uncertain version of the permutation flow-shop with unlimited buffers and the makespan as a criterion is considered. The investigated parametric uncertainty is represented by given interval-valued processing times. The maximum regret is used for the evaluation of uncertainty. Consequently, the minmax regret discrete optimization problem is solved. Due to its high complexity, two relaxations ...
متن کاملA Probabilistic Model for Minmax Regret in Combinatorial Optimization
In this paper, we propose a probabilistic model for minimizing the anticipated regret in combinatorial optimization problems with distributional uncertainty in the objective coefficients. The interval uncertainty representation of data is supplemented with information on the marginal distributions. As a decision criterion, we minimize the worst-case conditional value-at-risk of regret. The prop...
متن کاملThe Minmax Regret Shortest Path Problem with Interval Arc Lengths
This paper considers the shortest path problem on directed acyclic graphs, where the uncertainty of input data (lengths of arcs) is modeled in the form of intervals. In order to handle the interval data the minmax criterion to the regret values is applied, where the original objective function with interval coefficients is transformed into that of finding the least maximum worst-case regret, wh...
متن کاملSome tractable instances of interval data minmax regret problems: bounded distance from triviality (short version)
This paper focuses on tractable instances of interval data minmax regret graph problems. More precisely, we provide polynomial and pseudopolynomial algorithms for sets of particular instances of the interval data minmax regret versions of the shortest path, minimum spanning tree and weighted (bipartite) perfect matching problems. These sets are defined using a parameter that measures the distan...
