Production Lead Time Reduction in a Battery Manufacturing Unit using Lean Manufacturing

Abstract

Lean Manufacturing is an effective management philosophy for improving businesses in a competitive market by eliminating waste and improving operations. Value Stream Mapping (VSM) is the preferred way to support and implement lean. VSM is a visual illustration of the entire value stream (from customer order entry through purchasing, manufacturing and deliver the finished product to customer). This paper describes the reduction of production lead time in a battery manufacturing unit, and to deliver the products on time to customers. This involved mapping the activities of the firm, and identifying opportunities for improvement. Current State Map is prepared to describe the existing position of firm. The current state is analysed to identify sources of waste which are then eliminated. Future state map is prepared to show the improvement areas. The achievements of valve stream mapping are reduction in production lead time and inventory levels.
