this study presents the effects of project uncertainties on nonlinear time-cost tradeoff (tct) profile of real life engineering projects by the fusion of fuzzy logic and artificial neural network (ann) models with hybrid meta-heuristic (hmh) technique, abridged as fuzzy-ann-hmh. nonlinear time-cost relationship of project activities is dealt with ann models. ann models are then integrated with ...

In this paper, we propose a novel approach to determine an appropriate sequence to develop the components of a project management plan. Some newcomers to project management become overwhelmed due to the complex relations within these components. Network theory is a widely used tool in fields with complex relations within entities, but it has not yet been applied to configure a project managemen...

Although, the ultimate goal of WSNs is to place powerful data collection and analysis capability in the hands of scientists, current programming environments are cumbersome often requiring someone with a PhD in computer science in order to construct a basic program. Our research group is currently developing a next generation system-on-chip (SoC) for wireless sensor network applications. Theref...

The task of finding the crisp critical path has received researcher’s attention over the past two decades which has wide range of applications in planning and scheduling the large projects. In most cases of our life, the data obtained for decision makers are only approximate, which gives rise to fuzzy critical path problem. In this paper, new ranking methods are introduced to identify the fuzzy...

The purpose of the WAND demonstrator performance measurements was to evaluate how well the requirements of the WAND system design are met. This deliverable sums up the results of the performance evaluation. A special focus is put on evaluation of the WAND specific components that were designed and implemented within the project. The performance of the WAND radio sub-system, consisting of WAND r...

Measuring a network path’s quality is important. The main task of network measuring is to probing some criteria of quality, e.g., the end-to-end delay between server and clients, the current traffic conditions of the network, etc. The obtained performance information could be used to enhance user experiences not only as a feedback to adjust user’s terminal device but also to help network operat...

There is considerable interest in applications which transport isochronous data across a network, for example teleconferencing or Voice over IP applications. These applications require a network which provides Quality of Service (QoS) guarantees. While there are various networks which provide some form of QoS, there has been little investigation into the allocation of resources to network flows...

The beginning of the 21st century will present new challenges for largescale applications involving communication with, and coordination of, large numbers of geographically dispersed information sources, supplying information to a large number of geographically dispersed information consumers. Applications of this class will require an environment which supports longterm or continuous, reliable...

Weighted automata generalize a number of concepts found in discrete event dynamics systems of various kind. Semirings are used as a base algebra for describing weights which implies a variety different interpretations for particular application cases. In this project, we want to explore how theoretical results in fact boil down to algorithms and techniques that work in practice. The goal of thi...

The Operations Research Department at the Naval Postgraduate School educates experienced junior military officers in state-of-the-art operations research methods. As part of the educational program all officers go through a standard graduate course on network modeling. Within that course, students complete a class-long network modeling project of a real-world infrastructure system that solidifi...
