Idea of adaptation value stream mapping method to the conditions of the mining industry

Abstract

The Value Stream Mapping (VSM) method is one of the tools of the lean manufacturing methodology. It originates in the Toyota Production System (TPS). In Toyota this method was called “Material and Information Flow Mapping”. This technique enables analyzing and designing the flow of materials and information required to bring a product or a service to an internal or external customer. In the automotive industry it is widely used to optimize processes, eliminate waste, set proper level of stock and, last but not least, to actually see and understand the real process. VSM helps to understand and streamline work processes using tools and techniques of Lean Manufacturing. The aim of VSM is to identify, demonstrate and decrease waste in the process. It can serve as a starting point to help management, engineers, production associates, schedulers, suppliers and customers recognize waste and identify its causes. VSM can be a communication tool, but also may be used as a strategic planning tool. A value stream can be defined as all the actions — both value added and nonvalue added — currently required to bring a product (service) through the main production flows essential to every product [5].
