We introduce the multi-agent transportation (MAT) problem, where agents have to transport containers from their starting positions designated goal positions. Movement takes place in a common environment collisions between and must be avoided. In contrast other frameworks such as pathfinding (MAPF) or pickup delivery (MAPD), are allowed separate at any time, which can reduce makespan also allows...

In this paper we consider the so-called Multi-returning secretary problem, a version of Secretary problem in which each candidate has m identical copies. The case m=2 already been completely solved by several authors using different methods, but m>2 had not satisfactorily yet. Here, under conjecture certain (very likely true) uniform convergence results, provide an efficient algorithm to comput...

In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...

the problem of finding the minimum cost multi-commodity flow in an undirected and completenetwork is studied when the link costs are piecewise linear and convex. the arc-path model and overflowmodel are presented to formulate the problem. the results suggest that the new overflow model outperformsthe classical arc-path model for this problem. the classical revised simplex, frank and wolf and a ...

considering the increasingly high attention to quality, promoting the reliability of products during designing process has gained significant importance. in this study, we consider one of the current models of the reliability science and propose a non-linear programming model for redundancy allocation in the series-parallel systems according to the redundancy strategy and considering the assump...

contractor selection is one of the most important problem in supply chain and itsstrongly effect on firm`s performance. because a significant amount of auniversity`s budget assigns to construction contracts, contractor selection is animportant problem for the financial status of universities. since contractor selectionis a multi-criteria decision making problem (mcdm), lots of methods proposed ...
