Sheet metal material resources management in internal supply chains of engineering enterprise

Abstract

Improving the economic efficiency of industrial enterprises and ensuring their sustainable development depend, in particular, on the using of material resources management tools (MR) based on the principles of lean production using information technology. At the same time, the research of internal supply chains at enterprise allows identifying the main participants in the process, the material and information flows between them, determining the necessary change in the supply chain during the development of allocation innovations taking into account trends of digital economy. At the engineering enterprises, the managers face the task of increasing a sheet metal utilization rate in order to reduce unit technological costs, optimize the cost structure and increase net income. The relevance of this issue is confirmed by the theoretical and practical works of researchers in the field of cutting and packaging tasks, as well as in terms of the environmental problems which are because of increasing production and consumption waste. The purpose of the research is to develop tools of material resources management in lean production for sheet metal cutting at engineering enterprises with single or serial types of production. The tools are also based on the using of information technologies in economic system of an enterprise. At the previous stages of the research a situational analysis of sheet metal cutting and sheet metal material resources management at engineering enterprises was conducted, the main provisions of the sorting method of sheet metal MR after cutting were defined, approbation of certain aspects of the method was carried out using sheet metal cutting cards. The aspects related to micro logistical processes at an enterprise are specified in this article. Further research tasks are also identified.
