selecting an effective project plan is a significant area in the project management. the present paper introduces a technique to identify the project plan efficient frontier for assessing the alternative project plans and selecting the best plan. the efficient frontier includes two criteria: the project cost and the project time. besides, the paper presents a scheme to incorporate directed acyc...

Risk is not always avoidable, but it is controllable. The aim of this paper is to present new techniques which use the stepwise regression analysis to model and evaluate the risks in planning software development and reducing risk with software process improvement. Top ten software risk factors in planning software development phase and thirty control factors were presented to respondents. This...

This paper deals with the uncertainties present in the results of risk assessment of chemical installations and it examines their implications to land-use planning decisions. In particular, the results from the EU funded research project ASSURANCE are used as a case-study. Three types of land use planning approaches are considered, namely, a “consequence-based” approach, a “risk-based” using on...

risk management is one of the most important phases of project management and isthe most recently used by many researchers. in this paper, a fuzzy based method wasproposed which identifies different kinds of risks through the project life cycle.then, the project risk magnitude can be obtained in regards to five factors, namely“severity”, “occurrence”, and “not detection” which form fuzzy fmea a...

Allocation of construction risks between clients and their contractors has a significant impact on the total construction costs. This paper presents a system dynamics (SD)-based approach for quantitative risk allocation. Using the proposed SD based approach, all the factors affecting the risk allocation process are modeled. The contractor’s defensive strategies against the one-sided risk alloca...

Network planning methods for project planning and scheduling have been applied for more than fifty years including CPM, PDM, PERT and GERT (Fondahl, �96�; Fulkerson, �96�; Kelley & Walker, �959; PMI, ���6; Pritsker, �966), which can be widely applied to project planning fromareas as diverse as construction and R&D. However, these network planning methods are not very appropriate in cases where ...

Project success is assessed based on various criteria, every one of which enjoys a different level of importance for the beneficiaries and decision makers. Time and cost are the most important objectives and criteria for the project success. On the other hand, reducing the risk of finishing activities until the predetermined deadlines should be taken into account. Having formulated the problem ...
