Apart from estimating overall performance index, the paper also aims to highlight application of decision\u2010support tools for selection of appropriate candidate supplier in green supply chain management context.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Design\/methodology\/approach<\/jats:title><jats:p>In order to tackle incompleteness and imprecision arising from assigning appropriateness rating as well as priority weights against subjective performance criteria\u2010attributes, use of grey numbers was proposed. An efficient grey\u2010based supplier appraisement platform was established. Application of Grey\u2010Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and COPRAS\u2010G method were reported to solve the supplier selection decision\u2010making problem. The theory of grey numbers was utilized here to facilitate such decision modeling.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>Over the last two decades, growing concerns about ecosystem quality have stimulated to a renewed interest in environmentalism. Purchasing professionals should also be concerned and need to rethink purchasing strategies which have traditionally neglected environmental impacts. The \u201cgreen\u201d purchasing\u2010packaging in reducing and eliminating waste is a major concern in recent days. In order to help foster environmentally concerned purchasing strategies, this paper presents the findings of supplier evaluation strategy in an enterprise with enhanced degree of awareness and frequent applications of \u201cgreen\u201d purchasing. Environmental factors are identified that may reshape supplier evaluation decisions. The concept of grey numbers set has been adopted in this work. A case study reflects effectiveness of exploring grey relation theory in the context of green supplier evaluation.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>The major contributions of this work have been summarized as follows: development and implementation of an efficient decision\u2010making tool to support green supplier evaluation; an overall green performance index evaluation platform has been introduced; concept of grey numbers has been efficiently explored to facilitate this decision\u2010making; the appraisement index system has been extended with the capability to search ill\u2010performing areas which require future progress; and the proposed appraisement system is capable of reducing the number of green attributes towards computing grey appropriateness index thereby transforming into lesser number of green capabilities, thus, facilitating applying decision\u2010making tools like grey\u2010TOPSIS and COPRAS\u2010grey method for appropriate supplier selection from a set of candidate suppliers.<\/jats:p><\/jats:sec>","DOI":"10.1108\/20439371211273276","type":"journal-article","created":{"date-parts":[[2012,10,22]],"date-time":"2012-10-22T12:34:50Z","timestamp":1350909290000},"page":"395-418","source":"Crossref","is-referenced-by-count":24,"title":["Establishing green supplier appraisement platform using grey concepts"],"prefix":"10.1108","volume":"2","author":[{"given":"Nitin Kumar","family":"Sahu","sequence":"first","affiliation":[]},{"given":"Saurav","family":"Datta","sequence":"additional","affiliation":[]},{"given":"Siba","family":"Sankar Mahapatra","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"key":"key2022021720241624200_b2","doi-asserted-by":"crossref","unstructured":"Angell, L.C. and Klassen, R.D.
