Paper Title
Parameter Optimization of Sedan Cars for Proper Selection by Multiple Attribute Decision Making (MADM) Technique

Abstract
Automobile industry is the fastest growing industry today. In the competitive business the automobile companies have to pay attention for the cost of vehicle, its efficiency and service. Today, many auto makers are interested in the compatibility of standard vehicle for the best performance so they can reign over the present market scenario. Among various important parameters which considered being very important for the best car, most important primary parameters are mileage and cost for customers. automotive lightweight is quite important and active demand which indirectly increases the mileage, due to the requirements of automotive industry progress, energy saving and emission minimization. In this paper, optimization of sedan cars for the best and most suitable car has been done by considering eleven parameters which are quite important and active in demand for thirty three car models from different manufacturers with the help of numerical techniques (MADM Technique). Parameters are ground clearance, track width, wheel base, cost, fuel efficiency, engine capacity, turning radius, power, Curb weight, range and cargo volume parameters have greatest influence on the performance of the sedan car. Keywords - sedan car parameters, MADM technique, customer survey.
