Abstract: 

Many organizations consider Project management as an essential capability and attempt to achieve sustainable benefits through effective managenlent of Projects. Leading companies are managing their Projects more effectively to achieve competitive advantages and enhance their underlying profits. The purpose of this paper is to underline the need for Iranian organizations to adopt Project management systems. This paper provides an interpretative investigation of the issues concerning implementation of Project management for Iranian organizations. The study involves one of Iranian leading companies in Petro-chemichal industry. The results indicate that the organizational culture is resistant to change and there is no support of senior management for implenlentation of Project management. Based on the analysis conducted. The impacts of organizational learning and training are not truly realized. Moreover, dissemination of knowledge and Project histories among Project teams is not appreciated, and the need for Project management is not sincerely recognized. The other Iranian companies may find commonalities in problenls and issues raised and solutions proposed. This paper has a potential to put forward the practical solutions for Iranian Project practitioners to critically reflect on their current attitudes and put the use of organizational Project management into their practice.

Abstract: 

In this paper, we address a new problem in the context of Project payment scheduling when Project activities are allowed to be crashed with the purpose of maximizing the contractors net present value (NPV). We assume that the contractor is paid at some pre-specified points of time according to the volume of work performed. Upon completion of activities, the cost of their execution is paid. Two different approaches are used to determine the volume of work performed at so called review points. In the first approach, only completed activities are considered. In the second approach, any portions of the activities that are executed are considered. To increase the volume of work performed at the review points, the contractor may decide to crash some activities and as such possibly increases his NPV. As activity crashing costs the contractor money, a compromise needs to be made. Two mathematical models are developed to study each approach and hence help the contractor to make the best decision. These models offer a means of investigating whether it is advisable to crash some activities and are therefore of practical importance. It is shown that the contractor may increase his NPV, even when he pays for the activity crashing costs. The performance of the mathematical models is illustrated using a numerical example.

Abstract: 

in this research, it has been tried to collect many issues that S.T.P.C Project was encountered with. Moreover, Project risks for S.T.P.C are mentioned through Identified Issues in terms of different phases of the Project life time. Based on risk management theories, explained in the literature section, risk assessment is applied for the identified risks. Then, Risks are categorized through risk category matrix by analyzing risk probability of occurrence and risk inlpact on Project cost and time. On the following, some mitigation actions have been derived, in forms of recommendations, which are useful to cut down the probability and impacts of risks.There are some fields and areas in associated with the Project which can be expanded for typical Projects. They have been cited in conclusion section as main sources of Project risks. Besides, for next researches, some critical areas are recommended to be followed through Future Research mplementation.Costs of the Project due to delays on sub-Projects in S.T.P.C, calculated by S.T.P.C accountant as a research in 2006, in comparison with estlnlated Project costs, will show the importance of tools and techniques such as Risk Management through petrochemical Projects which can be applied to manage Project time and cost. Finally, a collection of experiential reconmlendations can be applied for petrochemical plants in Iran for the future.

Abstract: 

Project portfolio management consists of repetitive cycles of Project evaluation، selection and execution. Project portfolio selection is the main part of Project portfolio management. Organization identifies and prioritizes Projects that are mostly aligned with stated strategic goals while considering real-world restrictions and considerations that are related to scheduling and resource allocation. In this paper، a new comprehensive model for the Project portfolio selection problem over a planning horizon with multiple periods by maximizing profit is developed in which simultaneous selection، scheduling and resource allocation of Projects are considered. The model incorporates Project interdependency and strategies of Project divisibility، reinvestment، external investment and resourcing in different ways at the same time in choosing the best execution schedule for the Projects in real-life applications. In addition، resource and budget constraints، cardinality restriction، precedence relationship and scheduling، setup and resource costs are included in the model. Numerical examples under eight scenarios are presented to highlight the characteristics of the proposed model.

Abstract: 

ORGANIZATIONS WORLDWIDE ARE ADOPTING ENTERPRISE RESOURCE PLANNING (ERP) SYSTEMS. A NUMBER OF STUDIES DISCUSS THE IMPLEMENTATION AND SUCCESS OF SUCH SYSTEMS, BUT THE OBJECTIVE OF THIS PAPER IS TO EXPLAIN THE MAIN FUNCTIONS AND INTEGRATION SCENARIOS OF SAP Project SYSTEM (PS). WE WILL DISCUSS BUSINESS PROCESSES THAT CAN BE MAPPED USING SAP Project SYSTEM. SAP Project SYSTEM SUPPORTS COMPREHENSIVE FUNCTIONS FOR PLANNING, CONTROLLING, AND ORGANIZING ALL THE ACTIVITIES CARRIED OUT DURING A Project. IT MANAGES A Project STRUCTURES, DATES, COSTS, AND RESOURCES THROUGHOUT THE ENTIRE Project LIFECYCLE.
