Supplier Evaluation Process by Pairwise Comparisons

Abstract

We propose to assess suppliers by using consistency-driven pairwise comparisons for tangible and intangible criteria. The tangible criteria are simpler to compare (e.g., the price of a service is lower than that of another service with identical characteristics). Intangible criteria are more difficult to assess. The proposed model combines assessments of both types of criteria. The main contribution of this paper is the presentation of an extension framework for the selection of suppliers in a procurement process. The final weights are computed from relative pairwise comparisons. For the needs of the paper, surveys were conducted among Polish managers dealing with cooperation with suppliers in their enterprises. The Polish practice and restricted bidding are discussed, too.

Usability of Parental Control Application Features To Protect Children From Negative Internet Impact By Using MAGIQ Approach (Case Study In Indonesia)

“…It is a purpose to examine the consistency of selection from respondents. Pairwise comparisons can handle Koczkodaj such as scale [13] and Saaty scale [14] for the judgment. This study using Saaty scale (1-9 scales) which commonly for AHP method then the appraisal calculation apply Geometric Mean [15] for the weight average of questionnaires.…”

A Fuzzy MCDM Approach for Green Supplier Selection from the Economic and Environmental Aspects

“…In the literature, numerous techniques have been developed to select the most suitable suppliers or green suppliers based on specific methods including fuzzy AHP [3,[40][41][42][43], analytic network process (ANP) [6,29], data envelopment analysis (DEA) [6], MCDM approach [13, 21, 31, 33, 44-47], Green image Ratio of green customers to total customers and social responsibility [2,33,35] Green competencies Materials used in the supplied components that reduce the impact on natural resources and ability to alter process and product for reducing the impact on natural resources [2,33,34,36,37],…”

Development of a process reference model for construction supply chains

“…On the one hand, benefits associated with multiple sourcing are competition, assured supply and undisrupted supply of bulk materials along with improved market intelligence and improved supplier appraisal effectiveness (Benton and McHenry 2010). Other benefits associated with multiple sourcing in the manufacturing industry are lower prices for clients and production flow security (Kawa and Koczkodaj 2015), benefits that can also be reaped in the construction industry. The main weakness associated with multiple sourcing is high operating costs to maintain relationships such as information system maintenance cost, controlling, negotiation, audits and setting cooperation conditions (Choi and Krause 2006).…”

“…Usually this decision is made based on the cost-price imperative (Hillebrandt 1985) due to the fact that it minimises costs and risks of costs not covered by the bid (Hartmann and Caerteling 2010). Price, along with delivery time are considered threshold factors for supplier selection (Kawa and Koczkodaj 2015). Contractors must also consider how easy it is to replace the selected supplier in case of unforeseen events that dictate such a need and have alternatives ready (Benton and McHenry 2010).…”

“…For example, De Boer et al (2001) propose the use of operational research (OR) models because of their ability to enhance the effectiveness and efficiency of such decisions. Elsewhere, Kawa and Koczkodaj (2015) propose the use of consistency-driven pairwise comparisons for both tangible and intangible criteria to aid supplier selection. The supplier is notified of their selection and has to respond in acceptance or denial.…”
