ASSESSMENT AND SELECTION OF VENDOR IN A CONSTRUCTION-BASED ORGANIZATION: A MATHEMATICAL APPROACH
M. Magendran, R. Vikrama Prasad, M. Venkatachalam
Graph theoretic approach has been adopted for evaluation and selection of a builder. The characteristic parameters which affect the builder’s quality were identified based on the literature survey of research papers and also followed the factors chosen by different researchers. Based on these factors, a model has been developed for builder selection. During the application of graph theoretic approach, a digraph of characteristics which contributes to quality of builder has been developed further the interdependency of attributes as well as their inheritances has been identified and its representation in matrix form has been used for calculation of numerical index of the builder’s quality through variable permanent function. A single numerical index has been developed using graph theoretic approach for assessment and comparison of builder in manufacturing organization.
