Abstract

Supplier selection is recognized as a critical decision in supply chain management in process industries. In such industries the procurement department plays an important role in reducing purchasing cost and selecting appropriate suppliers. The supplier selection problem is a multi criteria unstructured problem. Several key factors like quality, cost, delivery time and warranty etc., are commonly involved in the supplier selection decision making process. In this paper a hierarchical decision support system was developed for selecting the best supplier by using analytic hierarchy process model. This model was illustrated with a case study in a cement industry.

Abstract

While driving, blind spot is a key phenomenon related to the visibility of the driver. Blind Spots play a vital role in road accidents. Reduction of blind spot area is very much required to reduce the accidents. In this paper, an attempt is made to overcome the problems of blind spot by optimizing the design parameters used in the rear view mirror design of heavy transport vehicles. The blind spot of the existing body structure was studied in a public transport. First the area of blind spot of the existing body structure was studied and then the optimal design parameters are ranked by Fuzzy Analytical Hierarchy Process (FAHP). FAHP was also used to determine the weights of the design parameters and ranking of the vehicle body structures though a case study.
