Papers by Keyword: Value Stream Map (VSM)

Abstract: Lean manufacturing could enhance the overall equipment efficiency (OEE) by decreasing process setup, changing over time, and eliminating unnecessary activities. Meanwhile, Lean quality tools and standard work procedures implementation increase daily production. This study investigates the role of Lean manufacturing in enhancing environmental performance besides the operational one relating to small- and medium-sized enterprises (SMEs) in manufacturing firms through a Lean framework compatible with any firm's limited resources and experience. The study uses tools that small enterprises could apply, such as project charter, value stream maps, and 5S, accompanied by a Kano questionnaire and market analysis. The study has been validated in a small-sized Egyptian candle manufacturing enterprise and successfully implemented. It was possible to increase daily production by 31.95%, reduce cycle time by 19.82%, increase inspection and packaging overall efficiency by 10%, and decrease raw material waste by 29.6%.

Abstract: Today every production worldwide has to improve their. Based on several concepts and philosophies such as Kaizen and others, it is possible to realize an increase of productivity. Since it is of great interest to know and to evaluate the improvement, a suitable method that allows not only analyzing the improvement of cost but also of time is of interest. Based on the value stream map (VSM) and the profile of cost and time (PCT) the author has developed the PECOTA method, a graphical method of analysis. The concept of investment in time and cost by PECOTA allows first-time analysis and evaluation of a change in a manufacturing process in an easy and fast way. The method includes also the possibility to define the limit of lean manufacturing with the current processes.
