Handoff Cost Minimization and Planning of Heterogeneous Integrated Overlay Networks: Meta-Heuristics Based Approach

Abstract: The wireless technology market has witnessed a complete paradigm shift as multiple standards and protocols are emerging almost every day. Each and every standard has its limitations and merits, which can be either masked or complemented by some other standards. The demands from the service providers are now sky-high and for the complete commercialization, it is expected that even with scarce network resources all kind of services would be provided, especially in a cost effective manner. This burning issue compels a service provider to roll out some integrated wireless networks to exploit the virtues of each. This chapter formulates the planning problem of an overlay network integrating particularly, 3G, WiMAX, and WLAN. The issue of planning is to establish proper connectivity amongst the three network standards which is unique in its nature. In the proposed planning approach, the authors have endeavored to minimize total cost for vertical handoff generated in the overlay network as well as the cost for wire line connection amongst the various network gateways of the overlay hierarchy. In this work, the authors have focused on the initial planning phase. For validating the novel planning problem, the chapter has taken recourse to simulated annealing (SA) and a well cited meta-heuristic H-II. The authors have also presented comparison of the performances of SA and H-II with a variant of distance based planning (DBP) scheme in this domain.

The State of Management Education in India: Trajectories and Pathways

Abstract: Management education in India, especially the one offered at the IIMs, is the most sought-after professional choice among the youth pursuing higher education and attracts some of the best and the brightest students. Despite the popularity and centrality of the management education in the higher education landscape, a serious assessment of the field of management education in India has been rather few and far between. While there had been sporadic reflections and occasional critiques, a critical stocktaking of the institutional and disciplinary aspects of management education has been long wanting. This introductory essay gestures towards an interrelated array of factors that have a bearing on the overall purpose, and future direction, of management education in India. Besides presenting synoptic overview of the essays collected in the volume, it particularly underlines the global geopolitics of the theory and praxis of management and underlines the need to incorporate the perspectives of the Global South to move beyond the prevailing Western ethnocentrism.

Indirect Taxes in Oligopoly in Presence of Licensing Opportunities

Abstract: This paper considers the relative efficiency of unit tax and ad valorem tax in a Cournot duopoly market in the presence of licensing opportunities after the announcement of the tax rates by the government. In case of fixed-fee licensing, if the unit cost difference of the firms is low and tax revenue of the government is high, then unit tax is more efficient than the ad valorem tax. If tax revenue of the government is low, then ad valorem tax is more efficient than unit tax. Ad valorem tax is more efficient than unit tax in the case of royalty licensing.

A hybrid approach for supplier selection based on revised data envelopment analytic hierarchy process

Abstract: For most managers, purchasing decisions are key decisions in the achievement of business organisation's strategic objectives. Appropriate supplier selection is necessary as it fulfils these important objectives of the organisation by maximising overall value to the purchaser, reducing uncertainty in supply, and by forming a long term, reliable relationship between buyers and suppliers. Supplier selection being affected by several conflicting factors requires an appropriate multi-criteria decision making approach. One of the recent approaches used for supplier selection is a hybrid data envelopment analytic hierarchy process (DEAHP) approach. However, this approach suffers from serious drawbacks as it uses counter intuitive priority vectors for inconsistent pair wise comparison matrices and also at times, it generate illogical weights for consistent pair wise comparison matrices as well. The objective of this paper is to present a revised DEAHP (RDEAHP) approach to overcome these drawbacks of DEAHP. The uniqueness of the research lies in the application of RDEAHP approach for supplier selection problem.

Data-dependent probability matching priors for likelihood ratio and adjusted likelihood ratio statistics

Abstract: We consider likelihood ratio statistics based on the usual profile likelihood and the standard adjustments thereof proposed in the literature in the presence of nuisance parameters The role of data-dependent priors in ensuring approximate frequentist validity of posterior credible regions based on the inversion of these statistics is investigated Unlike what happens with data-free priors, it is seen that the resulting probability matching conditions readily admit solutions which entail approximate frequentist validity of the highest posterior density region as well
