A Hierarchical Experimental Simulation Platform of Coking Production

The complexity of coking production and the correlations among the three major processes involved make it difficult to study and apply effective methods in practice. We have designed a hierarchical simulation platform for coking production in coke ovens for experiments and the validation of the methods used. To handle problems in processing and obtain the comprehensive production targets, the simulation platform provides reliable, easy-to-use conditions for coking production research, which has the functions of simulating processes, examining methods for experiments, monitoring production status and coordinating optimization. To implement these functions, the platform has a three-layer structure and flexible communication interfaces. Results of experiments have demonstrated the simulation platform’s effectiveness and feasibility.

Research on Regional Comprehensive Production Capacity of Hog Industry in China with the Constraints of Resources and Environment

This paper designed a systematic evaluation methodology to study the regional comprehensive production capacity of hog industry in China. A three-layer evaluation index system of comprehensive production capacity of hog industry was established. The index system included 26 indicators and mainly covered seven respects, namely natural resource condition, feed supply capacity, current status of hog production, costs and returns of hog production, agricultural foundation, support capability of animal science and technology, and ecological environment condition. Then based on the index system, applied entropy weight method, grey relational analysis and principal component analysis, the comprehensive production capacity of hog industry of 31 provinces and municipalities in China in 2000, 2005 and 2010 was evaluated respectively. The consistency of these three methods was examined by Mann-Kendall test. A combined evaluation was conducted and reasons led to the great variation in ranking for some provinces and municipalities during the period of 2000-2010 were analyzed. Applied hierarchical clustering method, 31 provinces and municipalities were divided into four groups and the regions which were appropriate for hog farming and which were not were figured out.
