OPTIMIZATION OF BUS BODY BUILDING METHODS BY INVESTIGATION OF THE EXISTING PROBLEMS AND RECTIFICATION IN ADDIS ABABA, ETHIOPIA

Abstract

The design of the bus body depends largely upon the performance requirements under various types of loading, operating and the road conditions.Nowadays for the passenger buses there are many local producers which construct vehicles based on local needs. The big challenges found in the bus body building companies are applying spurious materials, heavier bus bodies;non-uniform construction and absence of code of practice for bus body design and approval.In the competitive to stay these producers comply with the same requirements of their international counterparts without access to latest computation facilities. This paper explores the existing problems in the industry and proposes the right solution to optimize the bus body manufacturing. To achieve the expected research goals, the researcher randomly selected one hundred fifty locally manufactured buses. The tools used are; statistical analysis, Pareto chart/diagram, cause and effect analysis,field observation and literature survey.
