Abstract

Purpose

Successful implementation of construction projects is one of the crucial factors for the economic development of every country. The main part of the countries’ capital is allocated to civil and infrastructure projects annually, most of which are accomplished with delay. Construction projects are often criticized for overrunning time and budgets. Analyzing the factors causing delay is essential for omitting them and timely implementation of these projects. Due to the importance of oil projects, this study aims to investigate and analyze the factors causing a delay in Iran’s oil construction projects.

Design/methodology/approach

In this research, after a broad literature review, using the fuzzy Delphi method, a total of 75 delay factors were identified under 11 major categories of owner, contractor, consultant, equipment, labor, materials, design, contract and contractual relations, laws and regulations, environmental factors, and managerial factors. Then, by using the best-worst method, the factors were prioritized.

Findings

The results showed that sanction, governmental management systems, weak project management by the contractor, technical and managerial weaknesses of the consultant, financial problems and delay in payment by the owner, low efficiency of the equipment, low productivity of the workforce, changes in laws and regulations, inappropriate organizational structure linking to the project, changes in the design, and changes in the price of materials are the most crucial factors causing a delay in Iran’s oil construction projects.

Research limitations/implications

These findings are expected to have significant contributions to Iran’s oil construction industry in controlling the time overruns in construction contracts.

Originality/value

The main contribution of this study is to develop a comprehensive framework in which, causes of delay in Iran’s oil construction projects are addressed and prioritized.

Abstract

Purpose

The main aim of this research is to rank and prioritize the solutions to address the challenges for the successful implementation of talent management (TM) in government banks in Iran.

Design/methodology/approach

This paper has identified the challenges of TM implementation in government banks and proposed the solutions to address these challenges through a review of the extant literature. The identified challenges and solutions were ranked using two multi-criteria decision-making (MCDM) methods called PROMETHEE and VIKOR based on the insights from 20 senior managers of government banks in Iran.

Findings

The challenges and solutions were categorized into cultural, managerial, human resources and environmental-related factors. “Building culture of TM in organizations”, “making TM as an ongoing process in organizations”, “commitment of senior managers to TM process”, “managing TM pipeline” and “focusing on meritocracy in recruitment and selections” were ranked as the top solutions to address cultural, managerial, human resources and environmental challenges, respectively.

Research limitations/implications

The findings can provide a comprehensive view of different types of challenges and solutions in the TM process for government organizations and institutions. It also provides helpful insights for top managers to define their organizations' strategies effectively and to implement the TM process by ranking and prioritizing the solutions to address their challenges.

Originality/value

The main contribution of this study is to develop a comprehensive framework in which, identification of different types of challenges in the implementation of TM processes can be addressed and the approaches to remove or mitigate the effects of these challenges are ranked by using two well-established MCDM techniques.

Abstract

Purpose

This paper aims to select the best scenario for energy demand forecast of residential and commercial sectors in Iran by using particle swarm optimization algorithm.

Design/methodology/approach

In this study, using variables affecting energy demand of residential and commercial sectors in Iran, the future status of energy demand in these sectors is predicted. Using the particle swarm optimization algorithm, both linear and exponential forms of energy demand equations were studied under 72 different scenarios with various variables. The data from 1968 to 2011 were applied for model development and the appropriate scenario choice.

Findings

An exponential model with inputs including total value added minus that of the oil sector, value of made buildings, total number of households and consumer energy price index is the most suitable model. Finally, energy demand of residential and commercial sectors is estimated up to the year 2032. Results show that the energy demand of the sectors will achieve a level of about 1,718 million barrels of oil equivalent per year by 2032.

Originality/value

To the best of our knowledge in this study a suitable model is selected for energy demand forecast of residential and commercial sectors by evaluation of various models with different variables as inputs.

Abstract

Purpose

Project portfolio management (PPM) is a commonly used technique to align projects with strategy and to ensure adequate resourcing for projects. In this paper, to gain a better understanding of PPM dynamics, a system dynamics (SD) model was developed. To do so, an Iranian independent power producer was used as a case study in the energy sector; moreover, policy options were derived and generalized for such a developer company.

Design/methodology/approach

To cope with the complexity of business processes in a power producer company and to formulate an optimum policy, causal relations and loops were derived first and then state-flow diagrams were designed to simulate the problem in the system, as it is usual in the SD methodology.

Findings

The proposed model was applied to a real-world case study to rectify managers’ viewpoint about their business dynamics and to formulate new project portfolio strategies to improve the viability of the company. The model proved how a static portfolio analysis can misguide managers in planning their project portfolio strategies, and how effective feedback can improve PPM in developing companies in the energy sector.

Originality/value

Systems approach, especially SD methodology, has been rarely used to analyze PPM problems in the energy sector. This study highlights the implications of feedback and dynamics in PPM and tries to derive optimal value of portfolios.
