Objective: The aim of this paper is to propose a new approach to assess the aggregated impact of risks on the completion cost of a construction project. Such an aggregated impact includes the main impacts of risks as well as the impacts of interactions caused by dependencies among them. Methods: In this study, Monte Carlo simulation and Bayesian Networks methods are combined to present a frame...

project planning is part of project management, which is relates to the use of schedules such as gantt charts to plan and subsequently report progress within the project environment. initially, the project scope is defined and the appropriate methods for completing the project are determined. in this paper a new approach for the critical path analyzing a project network with random fuzzy activi...

It is obvious that the success of a project-based organization is dependent on its projects. A variety of tools such as the project excellence model, project management maturity models, the earned value method, have been developed in this regard, but there are still delays in projects because the projects have dynamic nature with non-linear relationships and feedback processes during the projec...

This paper explores the applicability of the concepts of absorptive capacity and ‘‘ba’’ to ex ante project risk. We develop a hybrid framework to explain knowledge transfer based on these concepts—one that proposes a hybrid transference process. We then apply this framework to develop a methodology and metric for assessing ex ante software project risk, the risk that a new technology introduced...

SLQAL (Waseda University Sakai Laboratory QALab team) participated in Phase-1 and Phase-3 of the NTCIR-12 QALab-2 Japanese subtask. This paper briefly describes our approaches. Our runs scored 25 points in Phase 1 and 35 points in Phase 3. An initial failure analysis shows that our system performs particularly poorly for Type-T questions as well as questions that require time expression process...

The wide dissemination and effective materialization of the foreseen benefits of dynamic virtual organizations require a holistic approach to understand, model, and develop the needed infrastructures and tools to support the full life cycle of this organizational paradigm. Under this scope, the ECOLEAD integrated project was launched with the aim of creating the necessary foundations and mechan...

S T m p o p p abies cry. In fact, crying is considered part of normal infant development. Noted psychologist Gwen Gustafson offers this scienific explanation: “Neonatal crying is a pecies-specific behavior which achieves ts likely evolutionary function (infant surival) by reliably eliciting responses from aregivers.” The great behavioral observer harles Darwin described his own baby’s istress i...

Expert judgement is still the dominant technique in practice today for estimation of software project size and effort. In this paper, two instruments are evaluated that have been frequently suggested as effective support for human estimators: checklists and group discussions. A student experiment has been conducted to investigate how checklists and group discussions help estimators to improve t...
