PERT-Planning for Sublevel Stoping

Bounds for Multilinear Sublevel Sets

The question in the form (1.2) was posed by Li, Tao, Thiele, and this author in [5]. Nonoscillatory inequalities of the form ∫ ∏ j |fj◦`j | . ∏ j ‖fj‖Lpj have been studied in [1],[2]. Oscillatory integral inequalities of this type have been extensively studied for n = 2, where one is dealing with bilinear forms 〈Tλ(f1), f2〉. The associated linear operators Tλ are commonly known as oscillatory i...

Pert 21

More than half a century after the debut of CPM and PERT, we still lack a project scheduling system with calibrated and validated distributions and without requiring complex user input. Modern decision support systems (DSS) for project management are more sophisticated and comprehensive than PERT/CPM. Nonetheless, in terms of stochastic analysis, they show insufficient progress. PERT 21 offers ...

Uniform geometric estimates for sublevel sets

This paper reconsiders the uniform sublevel set estimates of Carbery, Christ, and Wright [5] and Phong, Stein, and Sturm [17] from a geometric perspective. This perspective leads one to consider a natural collection of homogeneous, nonlinear differential operators which generalize mixed derivatives in R. As a consequence, it is shown that, in the case of both of these previous works, improved u...

ePERT: Extending PERT for Workflow Management System

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,...
