Lean manufacturing techniques and encountered problems

ABSTRACT LEAN MANUFACTURING TECHNIQUES AND ENCOUNTERED PROBLEMS Hüseyin Can USLU Department of Industrial Engineering MSc Thesis Supervisor: Prof. Dr. Kemal Güven GÜLEN In recent years, depending on the rapid development of technology, the competitive environment among businesses has begun to increase. In order for businesses to survive in a competitive environment, lean production systems are needed. It is a production system that does not contain any unnecessary elements in the lean production structure, but minimizes the causes such as error, cost, stock, workmanship development process, production area, waste, customer dissatisfaction by making continuous improvements. The purpose of lean production is to increase flow quality, reduce costs and shorten delivery times. The principles of this system are determined in line with customer requests and needs. In this study, the basic principles of lean production, seven basic waste concepts, lean production techniques, problems encountered in lean production and the relationship between lean production and Industry 4.0 are emphasized. By examining the current studies in the literature related to lean production, the sectors in which lean production systems are used, the techniques used in the transition to lean production, and the reasons why companies want to switch to lean production are investigated. A research model is outlined between organizational culture and lean implementation success. Keywords: Lean Production System, Lean Production Approaches, Problems Encountered in Lean Production System.
