With the rapid development of technologies, many production systems and modes has been
advanced with respect to manufacturing, management and information fields. The paper …

This study deals with the problem of sequencing feeding tasks of a single mobile robot
which is able to provide parts for feeders of machines on production lines. The mobile robot …

The routing of vehicles on road transportation networks is an area of great importance to
transportation planners within scientific literature. This field includes well known and studied …

Consider a directed graph G=(V, A) with a set of nodes V and a set of arcs A, and let c uv
denote the length of an arc uv∈ A. Given two nodes s and t of V, we are interested in the …

The preemptive single machine scheduling problem of minimizing the total weighted
completion time with arbitrary processing times and release dates is an important NP-hard …

We determine the sensitivity of a current optimal solution to a combinatorial optimization
problem to cost changes in a set of elements. In a recent study, the concept of regular set …

The travelling salesman problem (TSP) is an important combinatorial optimization problem
that is used in several engineering science branches and has drawn interest to several …

This paper presents efficient methods of combining preprocessing methods and tabu search
metaheuristic for solving large instances of the asymmetric travelling salesman problem …

We introduce a reduction technique for large instances of the traveling salesman problem
(TSP). This approach is based on the observation that tours with good quality are likely to …

In practice, due to the lack of information, imprecise variables which come from experts'
empirical data usually appear. In order to deal with these imprecise variables, uncertainty …
