Application of ISM technique for analysis of the procurement related attributes in JIT supply chain management
(Inderscience Publishers, 2014) Mishra, O.P.; Kumar, V.; Garg, D.
The fierce competition in selling a product has made us have to think differently. The supply chain is one issue in front of each production firm to compete with another and to get privilege of another. The excellence of the supply chain is possible only when the product is of the best quality while being cost competitive. The reduction of the production cost has become the focus point in reducing the overall cost of the supply chain. This paper focuses JIT procurement process in the SC to cut one the overall costs. To estimate the factors affecting the JIT procurement (JP) we have recognised the important attributes from the literatures. A questionnaire-based survey was carried out to give the ranking of the attributes found from literature and then an interpretative structural model (ISM) is prepared to link the levels of importance of the JP attributes among themselves. On the basis of levels of the attributes managerial staff are suggested to focus on the particular issues to make the JP successful, therefore making the JIT supply chain management successful even in the worst scenario.

In a variety of problem domains, it has been observed that the aggregate opinions of groups are often more accurate than those of the constituent individuals, a phenomenon that has been termed the "wisdom of the crowd." Yet, perhaps surprisingly, there is still little consensus on how generally the phenomenon holds, how best to aggregate crowd judgements, and how social influence affects estimates. We investigate these questions by taking a meta wisdom of crowds approach. With a distributed team of over 100 student researchers across 17 institutions in the United States and India, we develop a large-scale online experiment to systematically study the wisdom of crowds effect for 1,000 different tasks in 50 subject domains. These tasks involve various types of knowledge (e.g., explicit knowledge, tacit knowledge, and prediction), question formats (e.g., multiple choice and point estimation), and inputs (e.g., text, audio, and video). To examine the effect of social influence, participants are randomly assigned to one of three different experiment conditions in which they see varying degrees of information on the responses of others. In this ongoing project, we are now preparing to recruit participants via Amazon's Mechanical Turk.
