Corporate Networking for Strategic Advantage

M. R. Dixit and Ramachandran K

This paper attempts to conceptualise some of the thoughts that are emerging in the area of corporate networking. While some research has been done in this area in the advanced western countries, nothing so far has happened in India. The purpose of this paper is to put our thoughts together to raise research issues. Networking has been discussed in several social sciences areas, but not much in the management discipline. Some recent research findings indicate that corporations derive strategic advantage not only by competition but also by cooperation. Such cooperative networking can be either for survival purposes or for deriving strategic advantage. There can be different types of networking such as formal-informal networking, primary-secondary networking and industry-institutional networking. The nature of strategic networking indicates that it has to be dynamic undergoing changes over a period of time. Such changes are influenced by a number of factors including the stage of the organization and its products on the respective life-cycles.

Top Management Stresses : Suggested HRD Interventions

Pestonjee D M

One of the main areas in which HRD interventions are needed relate to organizational role stresses. An attempt has been made in this paper to examine the stresses of the top management executives and to suggest HRD interventions accordingly. The sample consists of 221 Top Managers. 'organizational Role Stress Scale' developed by Pareek (1981) has been used to obtain scores on different type of role stresses one encounters in his job.

Study of Urban Informal Sector with Special Reference to Pan Shops

Ramachandran K

Industrialization and the consequent urbanization of less developed countries has led to the growth of several small business activities which could be clubbed under the umbrella of Urban Informal Sector. The role and contribution of urban informal sector have been appreciated of late. This paper highlights the findings of a study of pan shops located in the urban sectors of Ahmedabad and Anand. There are very few entry and exit barriers to this business which can be started with very little capital and special skills. Although pan shops are known to sell ready made pans (which are made with arecanut, lime and bittle leaf) and cigarettes traditionally, these days many of them have diversified into toiletories, cosmetics and confectioneries. Profitability in this business is very high, but there are still resistance for several people to move into this business for social reasons. Shop keepers would not like their children to get into the same business. Pan shop keeping can be taken as a seed-bed for developing entrepreneurship.

Redundancy of Additional Alternatives and Solutions to Bargaining Problems

Lahiri Somdeb

In this paper we propose a new axiom called the redundancy of additional alternatives axiom, which is satisfied by the proportional solution. A weaker version of the same axiom is satisfied by the Kalai-Smorodinsky (3) solution. The Nash solution satisfies neither. This new axiom seems to be a reasonable compromise between accepting the independence of irrelevant alternatives axiom and rejecting it outright, from the realm of axiomatic models of bargaining.

Metric Rationalization of Bargaining Solutions

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.

Joint Determination of Optimal Inventory and Marketing Policies

Rao P Poornachandra

In this paper a mathematical model has been developed in which the interaction of Economic Order Quantities with marketing policies have been considered. The model assumes the demand as a function of the four marketing variables viz., selling price, advertising effort, distribution effort and product quality. The model also allows the possibility of a fraction of the items getting damaged.

An Approximate Algorithm for Reducing Dummy-Activities in a Pert Network

Gupta Omprakash K

A project is an enterprise consisting of several activities which are to be carried out in some specific order. The activities and the order in which they need to be carried out can be represented by a pert network. Two types of networks are commonly used: activity-On-Node (AON) and Activity-On-Arrow (AOA) networks. When networks are used, it often becomes necessary to draw dummy activities. Since the computation of project completion time is proportional to the number of arcs, including dummy, it is desirable to draw a network with as few dummy activities as possible. It has been earlier shown that the minimum-dummy-activities problem is NP-complete. In this paper we propose an approximate algorithm for solving the dummy activities problem. The algorithm is explained by an example.
