Abstract
Purpose
The Middle East and North Africa (MENA) region is known for its extreme weather conditions during Summer. A major determinant of the sustainability of the design of a building is its fenestrations. The purpose of this paper is to explore the problem of designing and locating windows on building facades such that a number of relevant criteria to the MENA region are optimised, including solar heat gain, privacy, daylighting and cost of installation.
Design/methodology/approach
A multi-objective optimisation problem is proposed with the focus on capturing the requirements of residential dwellings in the MENA region. Since the problem contains conflicting objectives that need to be optimised, a lexicographic approach is adopted. In order to display the Pareto curve, a bi-objective analysis based on the ε-constraint method is utilised.
Findings
The conflicting nature of the proposed problem is indicated via the Pareto optimal solutions yielded. Depending on the preference of criteria adopted in lexicographic optimisation, the location of the windows on the building façade tends to change. The bi-objective analysis indicates the importance of balancing out the daylight factor against each of privacy, solar heat gain and installation cost criteria. Furthermore, an analysis conducted in three major cities in the MENA region highlights the discrepancy in design alternatives generated depending on the local climatic condition.
Originality/value
This work proposes a novel mathematical optimisation model which focuses on producing a sustainable design and layout for windows on the facades of residential dwellings located in the MENA region. The proposed model provides designers with guidance through an automated support tool that yields optimised window designs and layout to ensure the sustainability of their designed buildings.

Abstract
Purpose
The purpose of this paper is to identify and model critical barriers to sustainable practices implementation in Indian oil and gas sectors by the interpretive structural modeling (ISM) approach.
Design/methodology/approach
In this paper, through exhaustive literature survey and experts opinions, 14 critical barriers were identified, and the ISM tool, which is a multi-criteria decision-making approach, was used to establish interrelationship among the identified barriers and to determine the key barriers having high driving power.
Findings
After analyzing, it was found that six barriers, namely, market competition and uncertainty (B7), shortage of resources (B8), governmental rules and regulations (B1), knowledge and training (B2), financial implications (B3), and management commitment and leadership (B5) were found to have high influencing power. These barriers need the maximum attention and organizations need to overcome these hindrances for the effective implementation of sustainable practices. From the driving and dependence power diagram, two barriers, namely, management commitment and leadership (B5) and knowledge and training (B2) were found to have the highest driving power and two barriers, namely, lack of green initiatives (B9) and lack of corporate social responsibility (B14) were found to have highest dependence power.
Research limitations/implications
The presently developed model is based on the experts’ opinions, which may be biased, influencing the final output of the structural model. The research implications of the developed model are to help managers of the organization in understanding significance of the barriers, to prioritize or eliminate the same for the practical implementation of sustainability.
Originality/value
This is for the first time an attempt has been made to apply the ISM methodology to explore the interdependencies among the critical barriers for Indian oil and gas industries. This paper will guide the managers at various levels of an organization for effective implementation of the sustainable practices.

Abstract
Purpose
Project risk management (PRM) and human resource management (HRM) are the two critical success factors (CSFs) for international project management. This paper aims to correlate these two CSFs, identify the human resource (HR) barriers, develop a hybrid model for risk management and develop strategies to overcome the HR barriers to effective risk management in international projects.
Design/methodology/approach
In total, 20 key HR barriers have been identified through a literature survey and verified by project professionals. These HR barriers are ranked according to their ability to trigger other barriers by analysing their interactions using the decision-making trial and evaluation laboratory (DEMATEL) method. Based on Ulrich’s revised model for HR functions, a hybrid framework for international PRM has been proposed.
Findings
DEMATEL analysis categorized nine barriers as cause barriers and 11 as affected barriers. The “PROJECTS” model proposed for HR strategy development suggests eight strategies to overcome these nine cause barriers. The hybrid PRM framework developed includes the effect of the HR dimension.
Research limitations/implications
This paper presents the generalized prioritization of HR barriers to international PRM. For a specific international project, the HR barriers and their prioritization may change slightly. The hybrid framework for PRM and the strategy development model suggested are yet to be validated.
Originality/value
Correlating two CSFs in international project management, i.e. HRM and PRM and ranking the HR barriers using the DEMATEL method is the uniqueness of this research paper. The hybrid framework developed for PRM based on HR functions in Ulrich’s revised model and the proposed new HR strategy development model “PROJECTS” are unique contributions of this paper.
