式中， 为 时刻加工元 和 之间的信息素； 为信息启发因子，表示轨迹的

In the formula, is the pheromone between the processing elements at all times; is the information heuristic factor, which indicates the relative importance of the trajectory; is the expected heuristic factor, which indicates the relative importance of the heuristic factor; The degree of expectation is the reciprocal of the rate of change of manufacturing resources; it is the set of processing element nodes that the ants can select from the processing element at the current moment. At the initial moment, it is assumed that the pheromone of each path is equivalent.

In the method, for the moment processing elements and between the information elements; for the information heuristic factor, representing the relative importance of the trajectory; for the expectation heuristic factor, to represent the relative importance of the heuristic factor; for the heuristic function, to represent the processing elements from the desired degree of transfer to the desired degree, for the inverter of the rate of change of manufacturing resources; for the ants at the current moment from the processing elements optional processing meta-node collection. At the initial moment, the default is that the information of each path is equivalent, set .

Where, is the pheromone between the processing element and at the time; is the information heuristic factor, which represents the relative importance of the trajectory; is the expected heuristic factor, represents the relative importance of the heuristic factor; is the heuristic function, represents the expected degree of the processing element from to, is the reciprocal of the change rate of manufacturing resources; is the ant from the processing element at the current time Starting from the optional set of processing element nodes. At the initial time, the default is that the pheromone of each path is equal.<br>
