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 ...
Desired: a phased implementation of ERP
(2001-10-15)
The business problem faced by ELIL currently
is how to cope with competition and improve
its market and financial performance. On pages
59 and 60 of the case, it was stated that the
competitors, because of their small ...
Multiple products, multiple constraints, single period inventory problem: a hierarchical solution procedure
(2006-10-29)
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 ...
Dr. A. P. J. Abdul Kalam in conversation with Neharika Vohra and V. Venkata Rao
(Vikalpa: The Journal for Decision Makers, 2009-11-11)
Neharika Vohra — Dr Kalam, our interest is in looking at the role of technology
in the overall developmental context. In the current economic scenario,
what are your thoughts on the role of technology? On the one hand,
even ...
Issues in the design of training programmes on e-governance
(Vikalpa: The Journal for Decision Makers, 2008-11-11)
The impact that an e-governance initiative can
make depends very much on not only the relevance
of the initiative, but also the capabilities
of the officers who are involved with the initiative during
the various phases ...
A heuristic procedure for one dimensional bin packing problem with additional constraints
(2010-03-31)
We proposed a heuristic algorithm to solve the one-dimensional bin-packing problem
with additional constraints. The proposed algorithm has been applied to solve a practical
vehicle-allocation problem. The experimental ...
Interactive GANTT charting: features,data structures and algorithms
(2010-03-18)
Gantt chart (or bar chart) is a popular tool for developing and displaying job schedules. This paper focuses on software that provides a Gantt chart interface to enable users develop job schedules interactively. Here the ...
