Delays are one of the biggest problems faced by the construction industry. Delays in construction projects have significant financial and social impact to parties involved in the projects. The main objective of this study is to explore the causes of delay in the Vale Malaysia Minerals Project (VMMP) in Lumut, Perak. This study was conducted by using a qualitative approach. A series of face to f...

In order to deal with imprecision inherent in the planning and scheduling of projects, various extensions of CPM (Critical Path Method) and PERT (Program Evaluation and Review Technique) have been proposed in the literature. The main aim of these studies has mainly been the application of Fuzzy Set Theory in the computation of activity start and completion dates, and consequently in the calcula...

the research on project scheduling has widely expanded over the last few decades. the vast majority of these research efforts focus on exact and suboptimal procedures for constructing a workable schedule, assuming complete information and a static deterministic problem environment. project activities are scheduled subject to both technological precedence constraints and resource constraints, mo...

Nowadays projects dynamicity and complexity make the control process highly critical. The existing planning and control techniques have frequently proved inadequacy to manage the present challenge. The paper proposes a simulative approach to managing with more effectiveness projects life cycle. The appositely developed simulation model is populated with both deterministic and stochastic element...

The ability to estimate the personnel time and costs required for the completion of programming and systems projects is an important managerial tool for the information systems department. This article presents a survey of the estimation techniques found in the literature by describing each technique and discussing its strengths and weaknesses. Some empirical evidence on how the various program...

Due to the uncertainty of software processes, statistic based schedule estimation and stochastic project scheduling both play significant roles in software project management. However, most current work investigates them independently without an integrated process to achieve on-time delivery for software development organisations. For such an issue, this paper proposes a two-stage probabilistic...

Tradeoff between time and cost is an important issue in planning a project. This paper deals with a stochastic Time-Cost Tradeoff Problem (TCTP) in PERT network of project management. All activities are subject to linear cost function and assumed to be exponentially distributed. The aim of this problem is to maximize the project completion probability with a pre-known deadline to a predefined p...

The successful completion of a software development process depends on the analytical capability and foresightedness of the project manager. For the project manager, the main intriguing task is to manage the risk factors as they adversely influence the completion deadline. One such key risk factor is staff training. The risk of this factor can be avoided by pre-judging the amount of training re...

Activity networks have been used to model complex projects with wide applications in the field of production, planning and control. Stochastic activity networks (SANs) require a priori distribution function (d.f.) such as normal, exponential, Erlang and others. In this paper, a development of the moments method based on Weibull distribution of activity time is presented. The method provides an ...
