Utilizing Value Stream Mapping for Scheduled Optimization of Heavy Duty Earth-moving Vehicles

Growth of business world these days created higher market competition, because the existing industrial market become more global and have penetrated the inter-states boundary. In this global competitive scenario every company claimed to own the excellence and competitiveness so that, probability to win the competition is greater. Their ultimate goal is to satisfy the customer with the exact product, quantity, and quality in the shortest lead-time. It can only be achieve if the company is able to create and implement effective and efficient processes in each of its line of their business. For this, Lean tools are used to focus on the continuous improvement of a company towards reduction of various wastes like inventory, transportation, waiting, motion, cost factory space, correction etc. It is a systematic approach for eliminating waste in every area of business, including customer relations, product design, process layout, manufacturing sequence/operation and supplier networks. The system includes a wide range of tools and technique that aims at reducing inventory and production lead- time and to enhance the value added time and thus optimize the whole maintenance schedule. In this paper, an attempt has made to reduce the production lead- time (Dummy axle of heavy vehicles) of an automobile industry through value stream mapping. The result shows reduction in waste and system responsiveness according to the changing customers" needs through value stream mapping, a lean tool.
