This paper presents an Integrated Production Management System (IPMS) that nas been developed for an operating surface coal mine in southern United States. The IPMS is an extension of the previously developed Integrated Data Environment for Analysis and Control of Energy Consumption (IDE-ACE) system which nas been used in the same mine over the last several years. The IPMS system manages multi-data...
Firstly, this paper analyzes the status of energy consumption in Henan Province, and then the improved GM (1, 1) model is used to predict the energy consumption and energy structure in the following several years; it shows that the energy structure is unreasonable in the coming years; coal is consumed too much and the ratio of natural gas, renewable energy and new energy should be increased. Finally,...
Energy tax implementation is critical for the environmental protection and economic sustainable development of China, and the production cost and energy consumption price will accordingly rise as a result of the extra energy tax cost incurring. In this situation, a clean living environment is helped to be established because of the declining social demand for traditional energy and the application...
Data envelopment analysis (DEA), based on relative efficiency, is an efficiency evaluation method for the same type of decision-making units (DMU). Using sequence data of 1995-2007 and production function including the stock of knowledge, this paper chooses the VRS DEA model based on the assumption of input orientation to measure annual energy efficiency of Jiangsu in the framework of total-factor...
The paper presents an analysis of energy consumption values for two machine energy wood harvesting technologies. Both technologies were used to produce woody fuels from logging residues, one focused on chipping and the other on bundling logging residues. The energy analysis comprised the built-in energy in the machines used, the energy contents of the fuels used and physical loads of machine operators...
