Interior design of passenger coaches using fuzzy optimization

Abstract

Passenger coaches are one of the most important mass transportation vehicles for inner city passenger transportation and the proper interior design problem of the passenger coaches affect both passenger satisfaction and service quality. Defining user expectation and meeting them is important to solve this problem, which naturally contains ambiguity and vagueness. The study aims to maximize the total passenger number together with providing user satisfaction while designing interior area of passenger coaches. User expectations are defined by a survey and new design is defined with respect to anthropometric measures of human body. The collected data used to establish a fuzzy mathematic model to capture the ambiguity and vagueness of the problem and the mathematical model is solved using fuzzy optimization with respect to the constraints.
