Comparing this connection number with state sort table the grade of a working procedure ' s connection number is judged , then the possibility of this working procedure is got 并将这一联系数与态势排序表相对照，来判断工序作业时间的联系数所处的态势级，从而得出实现该工序的可能性。
Given a new concept - gametal inbreeding relation coefficient , and proved it is a increase function by inbreeding coefficient f , it ' s reflect the relating degree from the aspect of informatics 提出了配子间的近交关联系数的概念，并证明了它是近交系数f的单调递增函数，从信息论的角度刻画了配子间的关联程度。
But it is difficult to determine the productive time of a working procedure , there is uncertainty of it . this uncertainty is random , fuzzy and intermediate uncertainty , which can be dealed by connection number method 然而在许多情况下，估计项目活动持续时间是非常困难的，项目活动时间具有不确定性，联系数是用来处理模糊，随机，中介不确定性的系统理论和方法。
The way of improvement lies in adopting a system posture ordering based on connection number to carry out aggregative assessment so as to make full use of hierarchical information of different weighted targets to give an aggregative assessment conclusion which satisfies reality 改进的办法是采用基于联系数的系统态势排序进行综合评估，以充分利用不同权重指标的层次信息，得出符合实际的综合评估结论。
Factors which influence productive time of a working procedure , can be divided into several grades , four grades in this thesis , that is : { absolutely completion , completion , probable completion , unable completion } . corresponding elements of state sort table are adopted , that is four elements state sort table . connection number expression is found by the method of weighted value 对影响工序作业时间的若干影响因素( f _ 1 f _ n ) ，可以根据需要将评判结果分为几个级，比如分为{肯定完成，能完成，可能完成，不能完成}四个，那么应采用相应元数的态势排序表，即四元态势排序表；然后运用加权平均法求出工序作业时间的联系数。
