in the real world, risk and uncertainty are two natural properties in the implementation of mega projects. most projects fail to achieve the pre-determined objectives due to uncertainty. a linear integer programming optimization model was used in this work to solve a problem in order to choose the most appropriate risk responses for the project risks. a mathematical model, in which work structu...

This paper describes the development of a fuzzy decision support system (FDSS) for the assessment of risk in E-commerce (EC) development. A Web-based prototype FDSS is suggested to assist EC project managers in identifying potential EC risk factors and the corresponding project risks. A risk analysis model for EC development using a fuzzy set approach is proposed and incorporated into the FDSS....

Since there are obvious uncertainties in task duration, the uncertainty will be passed step by step due to the precedence relationships among tasks. Therefore, one should pay attention to the robustness of project plan when scheduling the project. In this paper, the project plan robustness is evaluated as the probability of completing the project in the planning duration, the Monte Carlo method...

There are a lot of project planning (like Gantt chart (Gant, 1910)) and network-based scheduling methods (like CPM, PDM, GERT (see i.e. Kelley-Walker, 1959, Pritsker 1966)), they were developed for handling traditional (e.g. construction) projects. While these methods are appropriate for the operation level logic planning, scheduling, cost and resource allocation of traditional project manageme...

Abstract. Good project planning provides the basis for successful offshore well drilling projects. In this domain planning occurs in two phases: an onshore phase develops a project plan; and an offshore phase implements the plan and tracks actual progress compared to the initial plan that was created onshore. The reuse of project plans is already prevalent within the oil and gas industry. A Per...

The discipline of project management has been available for almost 40 years. This paper examines several factors that make the management of software development projects more dif®cult than the management of many other kinds of projects. These factors negatively impact the software project managers' success in estimation and scheduling, planning, responding to schedule and budget pressures, mon...

risk management is one of the most important aspects of project management that identifies, assesses and responds to project risks. although many papers have been published in project risk response, presented tools and methods are poor. hence, in this paper, we present an optimization model to respond project risk that seeks to optimize two key criteria of project: cost and time. the proposed m...

large and complex infrastructure projects involve various risk factors and successful implementation of such project depends on effective management of the key risk factors. this paper reviews the literature to identify essential risk variables associated with infrastructure projects. base of these risk variables and case studies of same projects, a survey is conducted to isolate and assess the...

A federation implies a loosely coupled system distributed across the internet or an intranet, where the participants can join in and leave the federation without breaking the federation. It also implies that participants can function on their own when they are not a part of the federation. This represents the reality of the supply chain member organizations who are independent businesses. While...

In the context of the so-called smart grid, the intelligent management of electricity demand, also referred to as demand side management (DSM), has been recognized as an effective approach to increase power grid performance and consumer benefits. Being large electricity consumers, the power-intensive process industries play a key role in DSM. In particular, planning and scheduling for industria...
