Abstract

The road map to competitiveness journeys through making all- round improvements in production planning, processes, and practices. Endeavors include elimination of all non- value- adding costs and redundancies while affecting possible reduction in lead times, inventories etc. Such redundancies in operations are identified by the lean tool termed as Value Stream Mapping (VSM), which helps visualize both product flows, through various workstations, as well as the information flows (used to control the product flows). VSM thus helps chart the manufacturing environment, by flowing the product at the pull of the customer, which is carried out in pursuit of perfection through continuous improvement. Using VSM many organizations have hitherto changed their existing layouts, material handling systems, inventory control to reduce the lead- time and work- in- process (WIP) inventories.

The present work describes the application of value stream mapping in an automotive company with a focus on piston rings machining operations. The case study reveals the various gap areas in the manufacture of piston rings for automobiles with aid of Value Stream mapping and subsequently the use of Lean tools applicable for more responsive operations, lead- time reductions and lowering inventories. Deployment of such lean studies is seen to be lacking in most of the automotive parts manufacturing companies.
