The charging methods were designed according to the characteristics of waste dumping of openpit metal mines, including charging based on the dumping amount of the total waste, multi-charging factors, exceeding standard punishment charging, and so on. The main charging parameter is based on the dumping area rather than the total amount of waste dumping. The charging model of waste dumping of open-pit mines was formulated, and the charging rate was divided into two parts, i.e., the standard charging rate and the differential charging rate. The standard charging rate was derived using the equilibrium dynamic model, whereas the differential one was obtained by establishing the fuzzy synthesized evaluation model.展开更多

The author explains and analyzes the ＂differential charges phenomenon＂ of universities in China by taking ＂Pareto optimality＂ as regulation standard and ＂Darwin optimality＂ as empirical standard, combining regulation standard with practice standard, realistic standard of value judgment with ultimate standard, and fairness with efficiency. This paper provides theoretical reference and an operation platform for application and implementation differential charges and the containment of corruption in college enrollment.展开更多
