Lean Practices for Waste Prioritising in Machining based Product

Many organizations have dedicated to improve the efficiency of operations through waste removal and reduction as a philosophy in the lean manufacturing initiative. This paper aimed to examine the application of lean production techniques in machining based product production systems, particularly for block cross member automotive parts. The Lean tool as known as value stream mapping was deployed for preliminary analysis while the analytical hierarchy process was applied to analyse the multi criteria decision making model for a waste selection process in the production system. The results show that the lean practices' approach by the VSM screened eight waste on the production system, known as Kaizen burst that influence to company' profit which is high access inventory volume in between process, high rework and reject volume, delayed supplier and deliver product on time to customer, wrong forecast data, changeover time require long time, low machine performance/ inefficiency machine, travelled time in-between process and lack on 5S activities. By using another one of the lean approach, AHP prioritises the waste found into rank and defines the most influenced waste to resolve.
