A company tackled the problem of designing a production system for cable harness production. The problem was being solved by using lean manufacturing tools focusing on the shortest possible product flow time through the production line and reducing the cost of individual operations. With the help of VSM tool, we ensured a regulated flow of material values in the production system and avoided unnecessary waste with sufficiently large safety supplies during operations. In order to achieve economic justification, we used the ABC method for calculating the incurred costs in the production system and calculated the product's own price. Based on the performed analyses of the product value flow and calculation cost analysis, we improved the initially designed production system. By comparing the results of the performed analyses and calculating the product’s own price, we achieved all the necessary requirements to produce a production system model.
