Abstract This research conducted in one construction company Indonesia, the was facing several problems, many projects that already ended have delays. Overdue payment of can reach Rp 252.544.148.-. For calculating late save researcher using Critical Path Method (CPM)-Crashing. CPM-Crashing method accelerate project duration by increase resource budget, so doesn’t need to pay overdue payment. Th...

The PERT technique of three estimates is a traditional, well-known approach to expert estimation. Estimators are asked for their optimistic, most likely and pessimistic estimation; then, a beta probability distribution is built to fit the data. Having a probability distribution for each activity allows a Montecarlo simulation to estimate the overall project effort with better accuracy. Still, e...

We discuss the running couplings in the standard model, SU(3) C ×SU(2) L ×U(1) Y , when the Higgs sector is replaced by SU(N T C) technicolor. Particular attention is given to the running of the couplings at momentum scales where technicolor is nonperturbative, and in this region we apply a relativistic constituent technifermion model. This model has been tested against the known running of the...

This study proposes that the entropy function provides a simple and useful tool for project managers to better cope with project uncertainty, and therefore better manage projects. The entropy function has a long and established history as a measure of uncertainty in information theory. If selected activities on PERT networks are modified by reducing their activity times by one or more time unit...

Meilijson and Nadas [1979] have obtained stochastic bounds in the convex majorisation sense to the critical path length of a project network with random activity durations. In this paper we present those results in a more general framework and, using similar techniques, obtain bounds for shortest route, maximal flow and reliability system lifetime. Subject classification: #488 Bounds for stocha...

Fat malabsorption in pancreatic insufficient cystic fibrosis (CF) patients is classically treated with pancreatic enzyme replacement therapy (PERT). Despite PERT, intestinal fat absorption remains insufficient in most CF patients. Several factors have been suggested to contribute to the persistent fat malabsorption in CF (CFPFM). We reviewed the current insights concerning the proposed causes o...

Workkows management systems support the deenition and execution of business processes. While business process reeingeneering tools use time information to simulate and optimize processes, the management of time is hardly supported in workkow systems. We introduce a concept for time management for workkow systems. It consists of calculating internal deadlines for all activities within a workkow,...

We develop a bicriteria model for the resource allocation problem in PERT networks, in which the total direct costs of the project as the first objective, and the mean of project completion time as the second objective are minimized. The activity durations are assumed to be independent random variables with either exponential or Erlang distributions, in which the mean of each activity duration ...

The following introduces CaDaDis, an extension to the architecture-independent VISTA toolkit. CaDaDis creates visible accounts of cognitive model behavior through a set of Categorical Data Displays. It includes a standard Pert Chart showing tasks by category (or resource), a Nonstandard Pert Chart that shows the temporal dependencies, and a Gantt chart that helps show occurrences of agent event...
