LEAN SIX SIGMA BARRIERS WITH POTENTIAL SOLUTIONS IN ELECTRICAL VEHICLE ASSEMBLY: A REVIEW

The purpose of this paper is to identify the various types of lean six sigma (LSS) barriers involved in the assembly process of electric vehicles (EV). An exhaustive literature survey was conducted to identify the critical barriers in LSS implementation. Four main barriers affecting the assembly process are transportation and handling, assembly line processing, EV assembly integration, and human resources and training. The main barriers were further separated into several sub-barriers. The potential solutions to address the sub-barriers are investigated. The implementation of these solutions will help automotive industries to achieve an optimized and economical high volume production, make operations easy, improve process flexibility, and develop human resource essential for the EV assembly process.
