An AHP framework of supplier evaluation with reference to high-value and critical items: A case study
(Inderscience Publishers, 2010) Debadyuti Das; Deepak Barman
This study developed a simple two-stage decision framework for evaluating suppliers of high-value and critical items with reference to a heavy engineering organisation by employing the Analytic Hierarchy Process (AHP). The first stage involved examining the qualifying criteria of the items on quality, while the second stage was concerned with identifying all other relevant attributes, including quality concerning high-value and critical items applicable to the organisation under study, and with finding out the relative importance of the same. The attributes were organised in a two-tier hierarchy showing four major criteria in the first tier and 17 subcriteria in the second tier. This enabled us to employ AHP to find out the relative importance of each individual subcriterion through pair-wise comparison between all major criteria and subcriteria by eliciting opinions from three experts. The findings indicated the quality/reliability of the items to be the most important criterion, followed by price and then technological capability of the suppliers. A group of five suppliers was evaluated on all 17 subcriteria with regard to their performance and the overall performance of the suppliers was compared on the factor scores obtained by each supplier. © 2010 Inderscience Enterprises Ltd.
Attractiveness of Varanasi as a tourist destination: perspective of foreign tourists
(2007) Debadyuti Das; Pratap K.J. Mohapatra; Sushil Kumar Sharma; Ashutosh Sarkar
The present paper examines the attractiveness of Varanasi as a tourist destination from the perspective of foreign tourists considering several important dimensions simultaneously. These are demographic characteristics of tourists, their expectation on touristic attributes of the destination as also satisfaction with the same and finally holistic impressions of the destination. A factor analysis carried out on 24 touristic attributes pertaining to the expectation of visitors gives rise to seven meaningful constructs. Results of step-wise multiple regression analysis between the perceived attractiveness and the above seven constructs reveal the importance of each of these seven constructs in explaining the perceived attractiveness of the destination. Holistic impressions of Varanasi reveal that it is a city embodying the essence of Indian spiritualism and mysticism with Ganges and Ghats forming the heart of the city. © 2007 Inderscience Enterprises Ltd.
