Eat, Drink and be Healthy: A Paradigm Shift for Linking Food and Beverages Industry with People's Knowledge and Institutions

Anil K. Gupta

The food and beverages industry has not yet established strong and vibrant linkages with the local communities to develop value added products and share the benefits. The paper lists seven models for building such linkages. The models range from mass sourcing the ideas and rewarding the selected ideas by acknowledging them on the package or otherwise. One can source even the product design from the people and every idea is reciprocated, acknowledged and license deal is negotiated. Likewise, different models involve people at different stages of value chain, or to different degrees and with various kinds of reciprocity.

Roadmap for Educational Innovation in Institutions of Higher Learning: Towards Inter-University Centre for Innovation

Anil K. Gupta

It is ironic that while searching for models that promote excellence, we have not made the outstanding teachers and researchers the hub of future reforms. The fact that in any field of social investigation or higher education, the top few ranks are always occupied by public institutions has not influenced the advocacy for private institutions in the name of improving quality. Surely, mere ownership cannot influence quality. But, having achieved quality, public institutions need to be supported. The roadmap for educational innovations looks at the initiatives taken at the level of students and faculty. The concept of faculty governance has been diluted in many institutions of higher learning. The bureaucratic structures have sapped lot of energy of the students as well as faculty. It does not matter whether people perform because meritocracy itself has suffered a great deal in appointments to various positions, consultation for policy and institutional changes and for creating future vision. Time has come to arrest these tendencies and rebuild the educational edifice. A proposal for establishing an inter-university centre on innovation is made to operationalize various suggestions.

FDI in Retail: A Global Perspective

Srikant Gokhale and Piyush Kumar Sinha

Allowing FDI in multi brand retailing has recently generated tremendous euphoria for some and fear for others. It is based on the notion that it will open floodgates for foreign retailers to invest and will change the retail landscape forever in India. When India is the only country in the world where the top five business houses with market caps running into trillions are into retail business, this issue becomes much more interesting. Most retailers in other countries do not feature even in the top 10 large firms. Also the evidence of last 20 years of globalization by retailers shows that there is no such case of domination of foreign retailers wherever markets for global retailers have opened up. Only limited numbers of retailer have entered into these markets that too with lot of caution as they have realised that retail thrives on local knowledge rather than transplanting global retail concepts, strategy and formats. The experiences in other emerging economies have shown that fewer foreign retailers have been successful while several failed as they could not comprehend local nuances, customer insights and fight local competition. In fact, in many countries the local retailers have better market shares, sizes and performances.

Path Relinking for Single Row Facility Layout

Ravi Kothari and Diptesh Ghosh

The single row facility layout problem is the problem of arranging facilities with given lengths
on a line, while minimizing the weighted sum of the distances between all pairs of facilities. The
problem is NP-hard. In this paper we present path relinking algorithms to solve large sized
instances of the problem. We use three different metaheuristics to generate sets of good quality
initial solutions and subject the solutions in these sets to path relinking. We present our
computational experience on 43 benchmark instances with up to 110 facilities.

Sensitivity Analysis for the Single Row Facility Layout Problem

Ravi Kothari and Diptesh Ghosh

The single row facility layout problem (SRFLP) is an important combinatorial optimization
problem where a given set of facilities have to be arranged in a single row so as to minimize the
weighted sum of the distances between all pairs of facilities. Sensitivity analysis for the SRFLP
has not been reported in the literature till date. In this paper we present closed form expressions
for tolerances of all SRFLP parameters. We also present heuristics to obtain upper bounds on
the values of these tolerances. Our computational experiments show that the heuristics obtain
exact values of tolerances for small sized instances. For larger sized instances, our heuristics
obtain good quality bounds on the values of tolerances for a large fraction of the problem
parameters. We also present a tightening procedure to improve on the upper bounds generated by our heuristics.

Scatter Search Algorithms for the Single Row Facility Layout Problem

Ravi Kothari and Diptesh Ghosh

The single row facility layout problem (SRFLP) is the problem of arranging facilities with given lengths on a line, with the objective of minimizing the weighted sum of the distances between all pairs of facilities. The problem is NP-hard and research has focused on heuristics to solve large instances of the problem. In this paper we present four scatter search algorithms to solve large sized SRFLP instances. Our computational experiments show that these algorithms generate better solutions to 26 of the 43 large sized benchmark SRFLP instances than were previously known in the literature. In the other 17 instances they output the best solutions previously known in the literature.

A Competitive Genetic Algorithm for Single Row Facility Layout

Ravi Kothari and Diptesh Ghosh

The single row facility layout is the NP-Hard problem of arranging facilities with given lengths on a line, so as to minimize the weighted sum of the distances between all pairs of facilities. Owing to the computational complexity of the problem, researchers have developed several heuristics to obtain good quality solutions. In this paper, we present a genetic algorithm to solve large SRFLP instances. Our computational experiments show that an appropriate selection of genetic operators can yield high quality solutions in spite of starting with an initial population that is largely randomly generated. Our algorithm improves the previously best known solutions for several benchmark instances and is competitive for the remaining ones.

How has the Indian Corporate Sector Responded to Two Decades of Economic Reforms in India? An Exploration of Patterns and Trends

Rakesh Basant and Pulak Mishra

In the context of various policy initiatives made during the last two decades to reform the Indian economy in general and corporate sector in particular, the present paper attempts to assess how the firms have responded to these policy measures and the resultant changes in the business conditions in a long run perspective. The paper finds that although the rate of growth of the Indian industry sector has not accelerated following economic reforms probably due to slow growth in agriculture and industrial productivity, investment in general and FDI in particular have shown considerable increase. Increase in competitive pressures during this period has forced the firms to adopt a variety of strategies. While reliance on mergers and acquisitions (M&A) has increased to restructure business and grow, the role of embodied and disembodied technology purchase has declined with firms relying somewhat more on in-house R&D. On the other hand, although strategies of building marketing and distribution related complementary assets continue to dominate the strategy of product differentiation, their role in a relative sense seems to have declined as these expenses as a proportion of sales show a declining trend. However, the emerging competitive pressures have raised the importance of sub-contracting/ outsourcing manufacturing, reducing the degrees of vertical integration. Interestingly, while cost-efficiencies do not show improvements, export orientation has increased across the industries significantly signaling enhanced global competitiveness of Indian firms, although imports have risen faster than exports. Overall, the observed trends of corporate response to economic reforms are interesting, but one need to systematically explore how M&A led consolidation and flows of FDI are linked to the adoption of various non-price strategies relating to technology and product differentiation. As economic reform deepens and competitive pressures build up, an analysis of these interactions would provide useful insights for understanding corporate behaviour and for making policy choices.

Tabu Search for the Single Row Facility Layout Problem in FMS using a 3-opt Neighborhood

Ravi Kothari and Diptesh Ghosh

Since material handling agents in a FMS are most efficient when moving in straight lines, a common layout of machines in a FMS is a single row layout. This allows a floor designer to model the problem of generating an optimal machine layout in a FMS as a single row facility layout problem (SRFLP). Due to the computational complexity involved in solving the SRFLP, researchers have developed several heuristics to solve large instances of the problem. In this paper, we present a tabu search implementation based on a 3-opt neighborhood search scheme. We also present a technique to speed up the exhaustive 3-opt neighborhood search process significantly. Our computational experiments show that speed up of the 3-opt search is effective, and our tabu search implementation is competitive. The results we present here are better than the currently known best layouts for several large sized benchmark SRFLP instances, and competitive for other benchmark instances.

Foreign R&D Centres in India: An Analysis of their
Size, Structure and Implications

Rakesh Basant and Sunil Mani

The study measures the contribution of MNCs to the generation of innovations from India. The focus is on innovations that are carried out in foreign R&D Centres. After having mapped out the size of this sector, the study develops a way of classifying them into two categories on the basis of their actual record with respect to performance of innovations. Further we survey the policies that are available in India to promote FDI in R&D services. The study also identify the characteristics of these foreign R&D centres in terms of a number of indicators like their, size, domain expertise, physical location and then it distils out the interaction of these centres with India's National System of Innovation. The latter is carried out through a primary survey. The contribution of this study is an identification of the size of foreign R&D Centres in India from official sources of data and its actual working. The study has thus a number of pointers for public policy for promoting this activity so that it is beneficial to the host economy of India.
