Primal and Lagrangian heuristics for minimum weight rooted arborescence problem
(2010-07-27)
Consider a rooted acyclic graph G with weights on arcs. In this graph, a minimum weight rooted arborescence (MRC) can be defined as one whose sum of arc weights is less than or equal to that of any other rooted arborescence ...
Multiple products, multiple constraints, single period inventory problem: a hierarchical solution procedure
(2010-03-31)
This paper presents the formulation and a hierarchical solution procedure of multiple
products, multiple constraints, single period inventory problem. The hierarchical
procedure decomposes the problem into a number of ...
A computer based crew scheduling system for freight trains in Indian railways
(2010-03-23)
This paper describes the design and implementation of an online PC-based crew allocation and management system for freight trains on Indian Railways. The software allows different rules to be used for calling the crew so ...
The minimum weight rooted arborescence problem: weights on ARCS case
(2010-03-24)
In a rooted acyclic graph, G, there exits, in general, several rooted (not necessarily spanning) arborscences. Depending on whether the graph has weights on nodes, on arcs, or on both, it is possible to define, with different ...
