【Abstract】 The concept of float rate was introduced. Integrating float rate with the toposorting of activities in network scheduling, a new method of coding and decoding was presented. Compared with GA applied to resource leveling, this method can avoid generating invalid individuals in GA operations, such as initializing generation, crossovering and mutation. This method was more simple and suitable than other methods. It can be widely used in network scheduling optimization.更多还原
