The objective of this paper is to introduce the work of information technology in the process industry. In the industry the time is used as the money. So here the main task is to save time. In the industry the maximum time spent due to the waste. Lean Manufacturing is a term that is used to reduce the waste from the industry. It also use the information system in the form of Kanban. Lean principles and techniques have been applied in a wide variety of organizations, from make-to-stock to engineer-to-order industries, and even in typical service sectors, such as healthcare. In order to apply lean principles in various areas, variants were developed of well known techniques, such as Kanban, Kaizen, SMED, and 5S. Here the discrete and continuous manufacturing benefits are distinguished by the value stream mapping. Here the Value stream mapping is used to first map the current state and then used to identify sources of waste and to identify lean tools to try to eliminate this waste. The future state map is then developed for a system with lean tools applied to it. This thesis focuses on the development of a simulation model of the industry.
