Value stream mapping in a job shop manufacturing and a hix mix low volume environment and an application in a manufacturing facility

In globalizing trade conditions, companies have entered into constant competition in order to respond to customers demands. With the spread of internet sales, flexibility has become very important for businesses. Despite increasing raw material prices and variable demands, companies try to produce without holding stock. Considering the customers who do not want to wait for a long time in order delivery and the increasing stock costs, the aim of the enterprises has been to produce just in time. The way to make just-in-time stock-free production is through lean production. Thanks to lean production and continuous improvement, all units involved in production keep themselves dynamic by constantly renewing themselves. Lean manufacturing systems focus on activities that are free from waste in factories and that create only added value with high efficiency and performance. Although the foundations of lean production date back to previous years, it still has a structure that maintains its importance. Lean transformation has ceased to be a production system only and has become a philosophy of combating waste, which is taught in lectures at universities. In this study, first of all, information about the concept of lean production is given and application techniques are explained. Lean manufacturing techniques are detailed in the study. What is the value? What is creating value for the customer? These questions were answered. With the value stream mapping technique, which is used as a lean manufacturing technique, activities that create added value for the customer have been revealed. Jobshop type production based on order is detailed within the production systems. Information is given about the concept of a high mix of production in low volumes to order. Wastes were identified with current and future state value stream maps for the enterprise where the application was made, and necessary improvements in processes and flow were suggested with various Kaizens.
