Cutting Plane Based Methods for Integer Programs

Sastry Trilochan

We develop a general cutting plane based paradigm for three standard problems: lot-sizing, plant location and general network design, with and without capacity constraints. Other methods for solving these problems like branch and bound and Lagrangean relaxation have not performed well in all cases. We explore some theoretical and computational issues. These methods have wide ranging applications in road and rail transport network designs, irrigation systems and communication networks.

A Compromise Solution for Claims Problems

Lahiri Somdeb

The purpose of this paper is to axiomatically characterize a Compromise Solution for claims problems which satisfies invariance under affine utility transformations. The more well-known solutions for claims problems do not satisfy this property. This is a major deficiency of the latter class of solutions, as they fail to predict appropriate responsiveness to risk aversion by ones opponents. Our solution overcomes this deficiency.

Women in Management in India

Parikh Indira J

This paper is in extension of the paper “Career Paths of women in Management in India”, W.P.No.884 by the same author. In this paper, the origin and the gradual movement of women's role and identity patterns are discussed in the cultural context. The process of transformation from the agrarian model of living to the industrial mode is emphasized in the first part of the paper. Empirical data has suggested that sexual identity rather than women's work is more important in predicting the respondent's traditional and modern approach to life. Traditional values and approaches continue to define and determine the lines of women, whereas some indications of modernity are noted among them. Women's role in management is then explored in the context of Indian culture, social design and formal work organization. Career paths of women in management in India are distinctly identified into three phases. The move from being job oriented to career oriented to profession oriented is discussed in detail. Issues of women in management in the organizational context are probed into and the future scenario in the cultural, organizational and role context is reflected upon.

Developing Small Holders Agriculture Through Changing Crop Composition

Naik Gopal and Babu K R

Small size of holdings of a large proportion of farmers is considered a major bottleneck in increasing the income of the people in rural areas. In India the proportion of small holders is increasing over time. Previous studies have suggested policies oriented towards non-prince factors such as increasing yield and changing crop composition for improving their incomes. This study examines how sericulture could be an ideal enterprise for small and marginal farmers in India. Analysis of primary data collected from 3 taluks of Karnataka state suggested that sericulture is far more attractive compared to competing crops in the respective areas in terms of net returns, cash flows and employment generation. Increasing silk production can also help in increasing foreign exchange earnings. Moreover, sericulture has other desirable features such as increased employment opportunities for women. Therefore, efforts towards popularising sericulture among small and marginal farmers could help in improving the living standards of these farmers.

A Partial Characterization of the Uncapacitated Lot-Sizing Problem with Start-up Costs

Kalro A H

We consider the facial structure of the Uncapacitated Lot-sizing problem with start-up costs. We show that under mild assumptions on the objective function cost structure, adding valid inequalities described by Wolsey (1989) to the linear programming relaxation of the problem guarantees optimal integer solutions. For the special cases of a time horizon of 3 or less, we show that the inequalities completely describe the convex hull of feasible integer solutions. We also identify a new class of valid inequalities for the problem.

Seed Industry in India Achievements and Prospects for growth

Gurdev Singh and Asokan S R

The paper enlists important policy measures taken to develop seed industry in India since 1947, progress made, and prospects for its growth. It reveals that the protectionist policy on seeds was abandoned in late eighties when seed industry was placed in Appendix I of the licensing policy. Subsequently under the New Seeds policy import of some seeds was placed under Open General Licensing while that of some others was permitted for two years subject to transfer of technology by the foreign company. Though impact of all such measures could not be seen immediately, the quality seed production has increased to 5.7 million quintals in 1989-90. The number of seed organizations in public and private sector has gone up to over 100. Seed multiplication alone has achieved a turn over of over Rs.3,000 million, about 50 pr cent of which was due to private sector. Few private companies have taken up seed research and are able to evolve more than 100 varieties/hybrids. However, still there is a big gap between production and requirement of quality seed. The requirement is estimated at 11.74 million quintals for 1989-90 and 22.19 million quintals for 2000 AD. The seed replacement has been far below the recommended rate for almost all major crops primarily due to non-availability of quality seeds of suitable varieties. Besides, there is good export demand for Indian seeds. Also to feed the teaming millions farm production must increase on continuous basis and productivity being the prime contributor to increasing production, seed quality must improve. Thus investment in research has good prospects and private sector must avail this opportunity to supplement public sector efforts. Biotechnology is a new hope as it ensures quicker multiplication and new strains. All this reflects on the bright prospects of growth for seed industry in India, the paper concludes.

Indian Oilmeals/Cakes Scenario, 1961-90

Rao V M

NCA (1976) has estimated that 5.75 million tonnes of concentrates are needed to bridge the gap between availability and requirement. On the other hand demand for milk is increasing year after year due to population growth, and raise in per capital income. Hence demand for livestock feeds, for economic milk production, will increase. This paper is an attempt to review consumption, production and trade related aspects of oil meals India. Cotton, groundnut, and rapeseed are major oil cakes in terms of consumption, and production, though there are side fluctuations in their relative shares. Estimated elasticity of price, and adult bouines one of the expected signs and stastically different from zero at 99% level. India is a major exporter of oil meals in the world and on an average 20% of production is being exported to developed economies of the world.

Some Thoughts on our Trade Unions

Sheth N R

This paper was prepared as a script for the S.D. Punekar Memorial Lecture delivered at the Tata Institute of Social Sciences, Bombay. It contains an attempt to review the state of art in trade unionism in India in the background of the mounting concern within and outside trade unions about the relevance of trade unionism in its present form. This concern is a product of some significant changes in the approach to management of industrial relations and the growing economic complexity in business and industry. It is argued that the primary function of trade unions is to provide a countervailing power for employees in relation to management and the society at large within the framework of the basic values of social equality, justice, fairness and human dignity. The development of trade unionism among blue-collar, white-collar and other categories of workers is briefly examined in the context of this primary function. The various social and political forces within and outside trade unions affecting their performance are explained in the course of the paper. Finally, some observations are offered on the role of trade unions as a part of the changing society in the foreseeable future and the crucial issues trade unions are likely to face.

Crisil Rating: When Does AAA Mean B?

Ragunathan V and Lahiri Somdeb

In this paper an attempt has been made to assess the quality of credit rating function being performed by CRISIL, hitherto the sole credit rating agency in India. With this objective, the paper attempts to answer two important questions, namely: a) Are CRISIL's standards of rating comparable to international standards? And b) Are CRISIL's rating internally consistent? The questions are answered by assessing the companies rated AAA by CRISIL on the Standard and Poor's (S&P) standards. It turns out that the CRISIL's AAA companies rate variously from B to A on the S&P standards! This indicates that CRISIL's credit rating standards are not only much below international standards, they are also internally inconsistent. CRISIL's rating reports on its AAA companies are carefully analyzed to see if the ratios employed by it are significantly different from those of S&P's so that their AAA ratings may be consistent vis-a-vis their own ratios rather than by S&P's ratios. Even this does not turn out to be so. CRISIL's rating reports are also analyzed for any qualitative reasons for the award of AAA ratings. No strong reasons are found. Thus it is concluded that the discriminating ability of CRISIL's ratings vis-à-vis risk and hence their meaningfulness and usability are in general questionable. This conclusion assumes all the more significance in the light of interest rates being allowed to be determined by market forces, and the interest rates in turn being linked to credit-worthiness of the borrowers more than ever before. Thus, the paper strengthens the case for more credit rating agencies both in the private as well public sector for making the rating business competitive. It also provides a more objective framework for assessing the performance of credit rating agencies in general.
