The routing of commodities is a tactical problem in supply chain management that aims to synchronise transportation services connecting a network of warehouses and consolidation locations. This paper considers the routing of commodities in a transportation network that is flexible in response to...

Transportation problem at its general form consists in finding an optimum transportation plan of a product from the receiving centers to consuming centers, so that the transportation costs to be minimal

In this paper, we consider a multi-index constrained transportation problem (CTP) of axial constraints with bounds on destination requirements, source availabilities, and multiple types of commodities. The specified problem is converted into a related transportation problem by adding a source, a...

In this paper, we develop a simple algorithm for obtaining the global solution to a small scale fixed-charge transportation problem (FCTP). The procedure itself is very quick. The proposed method solves FCTP by decomposing the problem into series of smaller sub-problems, which is novel and can...

This paper presents a Genetic Algorithm for the Vehicle Routing and Scheduling Problem with time windows and temporal synchronization constraints. That means that as opposed to the usual procedure, in addition to the usual task covering, some vertices must be served by more than one vehicle at...
