We present a two-phase heuristic for designing a capacitated degree constrained min sum arborescence. For a given directed graph G(V,E) where V={0, 1,…,n} with nonnegative costs Cij for each (i,j)

In 1997 two papers_new applying the metaheuristics Tabu Search (TS) and Heuristic Concentration (HC) tothe p-median problem were published in consecutive volumes of the European Journal of OperationalResearch. Here we apply the method of HC some of the data sets which were used for...

The rapid growth of telecommunication capacity, driven in part by the wide-ranging deployment of fiber-optic technology has led to increasing concern regarding the survivability of such networks. In communication networks, survivability is usually defined as the percentage of total traffic...

Effective storage space planning is important and complex, especially for container terminals with congested storage yards. The technique of yard template design, which normally specifies a set of storage locations in a group of yard blocks for export containers of various vessel services, is...

through the network. Afterwards, fleet scheduling creates a schedule for vehicles operated in the network. The strong relation … between flow routing and fleet scheduling makes it difficult to optimise the network cost. Due to this complexity, fleet … scheduling and network design are usually decoupled. We propose a new tactical network design model that is able to include fleet …

The classical scheduling literature considers many problems where a given set of jobs must be processed at minimum cost … practical situations where efficient scheduling affects revenue in much more general and realistic ways. First, we study two … make-to-order environments where efficient scheduling increases customer goodwill, thus stimulating demand in different …
