Deterministic Lot-Size Inventory Model When Delay in Payments are Permissible for a System with Two Storage Facilities

Shah Nitin and Shah Y K

In this paper a mathematical model of the economic order quantity with two storage facilities for single item has been considered under the condition that when the fixed delay in payments are permissible by the supplier. In practice, however, supplier allows some fixed delay in settling the account after receiving goods, and no interest charges are payable on the out-standing as longs as the account is settled within the specified delay period. The inventory system under consideration does not have sufficient space to accommodate the on-hand inventory. In such situation W units are stored at Own Warehouse (OW), and excess inventory is required to be kept in Rented Warehouse (RW). The holding costs at RW are higher as compared to OW. In this paper an attempt is made to analyse: a) when the system has both the warehouses facilities to accommodate the order quantity; b) when the OW has large capacity to store the on-hand inventory; c) when one does not wish to take RW services and stores maximum of OW capacity; and d) when simple EOQ model of single storage systems. The system suggest that when to hire RW services for more profitability among the given four alternatives. An expression for optimal order quantity is derived for all the above cases with an example to illustrate the methodology.

A Market Share Approach to Pricing Commodity Exports

Naik Gopal and Asopa V N

In this paper a market share model is developed for formulating appropriate export strategies for commodities by exporting countries. Assuming individual consumer in an importing country makes discrete choice regarding the source of a commodity or product depending on his/her perception of quality of the commodity or product from each sources and their prices, the aggregate demand of the importing country for each source is obtained. Based on this a market share model is developed assuming logistic distribution for the utilities. This market share model can be used by an exporting country to examine whether there is a premium or discount for its product/commodity and its magnitude which will help in determining (i) the relationship between relative prices and market share (ii) the level of price at which the country can earn maximum foreign exchange. This would help in formulating appropriate policies to influence freight-on-board (fob) prices thereby aligning with the changing international trade scene so as to effectively compete in the preferred markets to retain or increase market share which would maximize export earnings. The applicability of the model is illustrated using fennel seed export from India as an example.

Metric Rationalization of Bargaining Solutions and Respect for Unanimity

Lahiri Somdeb

In this paper we represent bargaining solutions by means of a metric which is defined on games, whereby the solutions are precisely those payoffs which are closest to being unanimously highest. Subsequently we study the properties of “welfare optimal rules” and rationalizability of bargaining solutions by symmetric metrics. This latter condition leads to anonymous bargaining solutions which satisfy “metric respect for unanimity”.

Canada-India Investment Promotion and Transfer of Technology with Special Reference to the Role of Joint Ventures in Retrospect and Prospect

Bhatt M C

This paper attempts to identify areas which offer good prospects for Indo-Canadian cooperation based on a study of industries where the existence of a 5-20 year technological gap makes Canadian technology particularly appropriate. It is argued that the Free Trade Zones (FTZ) and 100% Export Oriented Scheme (EOS) create a particularly favourable climate for technology transfer and that opportunity for collaboration also exists through Third Country projects.

Monotonicity of Compromise Solutions with Respect to the Claims Point

Lahiri Somdeb

In this paper we establish that a family of well-known normed compromise solutions for two-person claims problems respond appropriately to changes in the claims point.

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.
