1¡¢After each update iteration, particle population  are arranged in descending order according to the size of the fitness values. If the objective function  obtained  the minimum value  , then take the fitness value smaller particles of  the rear half  directly into the next generation (if the objective function obtained the maximum value  , then take the fitness value larger particles  of the first half  directly into the next generation).  The remaining particles placed in a pool of hybrid genetic  for crossover   to generate offspring  generations  of  the same number of the  parent generations. Offspring and parent particles are compared  and the smaller fitness value  half  particles taken into a after generation   to    constitute a new generation of particle swarm   with  direct taking  into  the next before.     
2¡¢In a closed circle with a node on the critical path for the start and end node  ,     the sum  time of all key commissioning activities  must be greater than the sum of  the circle's non-critical commissioning activities¡£
3¡¢While x and y are the average duration and  compression time of a closed circle on the critical path of  commissioning activities ,a and b are the average duration and compression time of a closed circle of the non-critical path of commissioning activities , c is mean square variance of commissioning activities of the closure ring of the j-th   , and d  is the constant for the p-th closed loop under a predetermined level of compression.
