In a stochastic interdiction game a proliferator aims to minimize the expected duration of a nuclear weapons development project, while an interdictor endeavors to maximize the project duration by delaying some of the project tasks. We formulate static and dynamic versions of the interdictor’s decision problem where the interdiction plan is either pre-committed or adapts to new information reve...

The purpose of this study is to evaluate PERT-based critical paths new service development (NSD) process for renewable energy investment projects. In context, a novel three-stage model has been proposed. the first stage, 10 different steps in NSD are weighted by considering 2-tuple hesitant interval-valued Spherical fuzzy IVSF DEMATEL approach. second 26 identified. Moreover, third stage includ...

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...

This paper presents a hybrid heuristic for constrained resource allocation in PERT type networks. Here, the assumption is made that the constrained resource is renewable for allocation to the activities of project. In addition, we consider finish-start precedence constraints with zero time lag. The activities durations are independent continuous random variables, preemption is not allowed and r...

Retroviruses are known as the causative agents of numerous animal disorders. In humans, this virus family is responsible for AIDS, certain forms of leukemias, and some neurologic disorders. The development in our laboratory of an ultrasensitive test for the retroviral enzyme reverse transcriptase has made possible detection of retroviruses present at very low concentration [1]. This test, the s...
