Life Cycle Cost Modeling for Heavy Commercial Vehicles

Abstract

Commercial vehicles play a very important role in the economy of our country with road transport accounting for 60% of goods movement. With substantial investment in Road transport by 2020, the number of vehicles and goods movement will go up. Scientific use of resources is to be encouraged not only from economic perspective but also from the environmental point of view besides conservation of resources for future generation. A survey conducted among some fleet operators showed that most of them are not using scientific principles in fleet augmentation or fleet replacement. To do that properly, the issues in developing a LCC model for HCV under Indian conditions identified and the methodology for overcoming it using reliability analysis and point process models discussed. Finally a framework developed for estimating corrective maintenance cost by using Non-homogenous Poisson process power law model in estimating expected failures sub-system wise using RBD approach and building LCC Model for HCV Fleet operators.
