Crew Scheduling in Indian Railways - A Case Study of Vadodara Division Passenger Train Crews

G. Raghuram, V. Venkata Rao, and Saha Jahar

In this paper we discuss the crew scheduling problem in Indian Railways and propose a methodology to minimize crew requirements. In Particular, we deal with the scheduling of passenger train crews in Vadodara Division of Western Railway. In Part-I of the paper, we describe the organization of Indian Railways, highlight the decision making process and give a brief description of the crew categories. We end Part-I by giving the regulations relevant for the scheduling decisions and a formulation of the problem as of determining a 'crew link' that requires minimum number of crews. In Part-III we describe the 'A-D Sequence' methodology and discuss how this is used in evaluating a 'Crew Link' for the drivers of express trains in Vadodara Division. In conclusion, we remark that the methodology is very general and it could be used for scheduling of all category of crews for passenger trains.

Dividend Rate and Variation in Share Prices: An Exploration into their Inter-Relationship

Ravindra H. Dholakia and Bhat Ramesh

Return and risk are the two acknowledged characteristics affecting investment decision of investors in securities market. The literature on the relationship between these two characteristics provides ample evidence about the interdependencies between them. The present study takes a view that risk should not be considered a one dimensional variable. An attempt has therefore been made in the present paper to decompose this characteristic into risk in dividend and uncertainty in capital gains. Two alternative explanations for the nature of their interdependencies and provides cross-section-one period analysis of dividend and share price variables. The empirical evidence supports the hypothesized relationships between the two dimensions of risk.

Determinants of Error Variance in Individual Child Analyses for Studying Integrational Capacity

Singh Ramadhar

In research on information integration by children, integrational capacity of a child is ascertained by the number of statistically significant main effects in analysis of variance for the child. Such an approach has an obvious bias, for the error variance may be bigger for younger but smaller for older children. Analyses of error variance from individual child analyses of four previous experiments on prediction of performance yielded mixed results. The mean error term sometimes decreased, sometimes increased, and sometimes remained the same over increasing age of children. The number of cues in the integration task and the nature of judgment seemed to be better predictors of error variance than the age of children. It seems that a study of integrational capacity must as a rule check on response variability along with the number of statistically significant main effects over ages.

Organization of the Future: A Strategic Organization Perspective

Khandwalla P N

In the light of research on organizational design, the paper outlines an effective design for the strategic organizations of developing societies. Strategic organizations are defined as those organizations with the mission of further growth and development of the sectors they are serving. The data on 31 leading Indian central public sector enterprises indicates that the postulated effective organizational design for Third World strategic organizations is feasible. The data on 5 strategic Indian organizations indicates that rapid, sometimes spectacular improvement in productivity and other indicators of performance accompany management changes towards the design postulated to be effective for strategic organizations.

Prediction of Son Performance in Easy through Difficult Exams by Indian Parents

Singh Ramadhar and Mehta Mridula

Prediction of exam performance from information about motivation and ability of students by Indian subjects always supported an adding-type rule. As this rule implies that motivation is equally effective with persons of low through high ability, it may be regarded as reflective of an idealistic philosophy. The present research tested the hypothesis that a multiplying-type rule which implies that motivation is more effective with persons of high than of low ability may be used by Indian subjects if the situation demands realistic estimates. Twenty-four couples expressed expectations from their only-son in easy through difficult exams to school principal confidentially. Predictions by mothers obeyed the multiplying-type rule; those by fathers obeyed the adding-type rule. Exam difficulty changed pattern in father's judgments but not in mother's judgments. However, parents held a similar belief: Effectiveness of motivation increases with sons of high ability but decreases with sons of low ability as difficulty of exam increases. Of the three possible explanations for the effects of exam difficulty, changes in weight of information seemed to be the most parsimonious.

A Goal Programming Model for Selection of Integrated Rural Energy Sytems

P. R. Shukla and Moulik T K

This paper presents a goal programming model for selection of Integrated Rural Energy System (IRES). The decisions involve (i) selection of a mix of energy generating systems and (ii) allocation of energy from these to different end-uses. These decisions are made considering several goals such as budget requirements, cost minimization, energy demand and supply, fuel-wood conservation etc. A pre-emptive priority structure for goal achievement is considered. The formulation thus esults in a mixed integer linear goal programming (MILGP) model.

National Cost of television in India in 2000 A.D. : Socio-Economic and Political Implications and Issues

Srivastava Uma Kant

The rapid expansion of TV coverage has opened up possibilities of this medium to be used as a developmental communication tool. The analysis in this paper has indicated that only 12 per cent of the population residing in the areas with the reach of the TV signals can only watch the TV at present. The simulation exercise reported in this paper indicates that unless some major policy interventions are made, only 40 per cent of people would have access to TV programmes even in the year 2000 A.D. The profile of these viewers indicates that bulk of these viewers would be from the urban area and top three brackets of consumption expenditure in rural area. The paper has discussed some of the socio-economic and political implications of this profile of viewership. This calls for a multi-pronged policy thrust in remedying the situation of skewed access to TV in India, widening the knowledge gap between 'haves' and 'have-nots'. This paper has suggested three such areas policy of interventions. The implementation of suggested interventions would also have implication for production planning, fiscal measures and support of village panchayats and local bodies and school systems. These aspects need to be taken into account in communication planning for the year 2000 A.D.
