ric tensor of arbitrary signature. The main topic of interest is those cases where the metric tensor is assumed to be nondegenerate. In the literature, manifolds with degenerate metric tensors have been studied extrinsically as degenerate submanifolds of semi Riemannian manifolds. One major aspect淡紫色花 发表于 2025-3-27 03:08:57

Precedence Diagramming,ry work, as we could see it in the time consuming network drawing process. The most serious problem with CPM is that we cannot describe activity interdependencies in an adequate way. According to the CPM definitions (see Def. 2-1 and 2-2) an activity can start only when all the preceding activities显微镜 发表于 2025-3-27 10:42:46

PDM Least Cost Scheduling,inimize the total project costs to a given project duration. Despite that the advantages of this method are apparent, there can hardly be found industrial applications for this method. The main reason for this is that finding proper cost data is very tiresome. This process can sometimes be longer thCANE 发表于 2025-3-28 00:36:48
