Robust Shortest Path Problems with Two Uncertain Multiplicative Cost Coefficients
نویسندگان
چکیده
We consider a robust shortest path problem when the cost coefficient is the product of two uncertain factors. We first show that the robust problem can be solved in polynomial time by a dual variable enumeration with shortest path problems as subproblems. We also propose a path enumeration approach using a K-shortest paths finding algorithm that may be efficient in many real cases. An application in hazardous materials transportation is discussed and the solution methods are illustrated by numerical examples.

Robust shortest path problems with uncertain costs
Data coming from real-world applications are very often affected by uncertainty. On the other hand, it is difficult to translate uncertainty in terms of combinatorial optimization. In this paper we study a combinatorial optimization model to deal with uncertainty in arc costs in shortest path problems. We consider a model where feasible arc cost scenarios are described via a convex polytope. We...
متن کاملRecoverable robust combinatorial optimization problems.dvi
This paper deals with two Recoverable Robust (RR) models for combinatorial optimization problems with uncertain costs. These models were originally proposed by Büsing (2012) for the shortest path problem with uncertain costs. In this paper, we generalize the RR models to a class of combinatorial optimization problems with uncertain costs and provide new positive and negative complexity results ...
متن کاملRobust optimization with incremental recourse
In this paper, we consider an adaptive approach to address optimization problems with uncertain cost parameters. Here, the decision maker selects an initial decision, observes the realization of the uncertain cost parameters, and then is permitted to modify the initial decision. We treat the uncertainty using the framework of robust optimization in which uncertain parameters lie within a given ...
متن کاملDecomposition approaches for recoverable robust optimization problems
Real-life planning problems are often complicated by the occurrence of disturbances, which imply that the original plan cannot be followed anymore and some recovery action must be taken to cope with the disturbance. In such a situation it is worthwhile to arm yourself against possible disturbances by including recourse actions in your planning strategy. Well-known approaches to create plans tha...
متن کاملHaving a Plan B for Robust Optimization
We extend the standard concept of robust optimization by the introduction of an alternative solution. In contrast to the classic concept, one is allowed to chose two solutions from which the best can be picked after the uncertain scenario has been revealed. We focus in this paper on the resulting robust problem for combinatorial problems with bounded uncertainty sets. We present a reformulation...
