哈尔滨工业大学工程硕士学位论文 哈尔滨工业大学工程硕士学位论文 -II- -II- Abstract Heating industry of every city is developing with the economic growth, at the same time energy sources and environment had been as the first problem. At the precondition like this, this paper aim at current character of our country and construct of energy, link to the best prevalent heating forms, adopt grey element analysis and hiberarchy analysis as the mathematical method, the total strong point of each contrast project as the objective function, then comprehensive evaluate in the target system of taking economy, social, entironment, technology and energysaving as main body, at last get the best heat souce fuel and its best eligible use method. The economical analysis includes two main factors: total investment and operating expense. On the basis of the former results, this paper adopt capital time value theory, and achive the total expense per year piece area. The social analysis is the preferential policy of our country and the safe degree of the project; the technological analysis included the advance, the mature, the automazition of the technics and applicability; the energysaving rate is the character of clean coal can decrease coal consuming. The three targets as above all adopt the whiten mace function which come from grey evaluation theory to valuate. The environment analysis takes the pollutant emission as the target, gradually valuate the lost brought into by pollution through the hiberarchy analysis. When all the targets are valuated, the paper calculate by the grey element analysis, get the best project. The paper still analyze the sensitivity of the last conclusion, and get the change of every project strong point when the ash content, the sulfur content, the price of coal and the price of each fuel is changing. Keywords: Heating souce; comprehensive evaluation; environment factor; sensitivity analysis -III- -III- 目 录 摘 要···············································································
