In order to plan its time-tables, a road transport corporation needs to have reliable information on the lead-factors on various bus-trips that are currently operated. Existing information does not permit determination of load-factors on segments of trips, but provide only over-all trip-wise...

This paper develops a computational algorithm for estimating the mean objective function value of a stochastic linear programming problem of the passive or wait-and-see type. The algorithm is applied to a problem connected with design of a ‘milk-grid’ in India and is found to be...

This paper discusses minimum matching in a trinomial doubly convex bipartite graph. The graph consists of three categories of arcs forming a doubly convex structure. The matching involves lexicographical minimization in required order of categories. Due to the special structure of the problem,...

This paper discusses an approach to compute a lower bound on fleet-size in variable-schedule fleet-size problem. The lower bound is computed in two stages. In stage one, a fixed-schedule fleet-size problem is solved for a relaxed set of trips where each trips is assumed to be departing at its...

Two alternative explanations have been proposed earlier to rationalize the participation of risk averse individuals in unfair lotteries within the framework of the von Neumann-Morgenstern expected utility hypothesis. One relies on the “thrill of gambling” while the other postulates that...

Rural roads can play a key role in promoting both economic and social development at the village level. However it is estimated by the National Transport Policy Committee that providing all-weather access to all villages in India will require an investment of Rs. 110 billion. This paper...

This paper discusses construction of a model to minimize fleet-size required to operate a time-table subject to a maintenance constraint. The constraint requires that vehicles be provided maintenance at least once every two days at a specific location. A heuristic algorithm was devised which...

This paper describes experience with application of operations research techniques in planning infrastructure for the Dharampur taluka in Gujarat. The work done covers four principal areas: 1. Design of a road network 2. Location of service centres 3. Development of an inter-active computer...

Genesis and Function: SEBI was created in 1988 to reform and regulate the securities markets in India. It was given statutory powers in 1992 and assigned the following functions and responsibilities:  Make rules and regulations for various agencies connected with the securities markets. ...

The Capital Asset Pricing Model is a single period model which specifies a linear relationship between return on an asset and return on the entire market. The model is widely used in literature as if a portfolio of securities can be designed based on a unique value of systematic risk. In this...
