Abstract

Purpose

The purpose of this paper is to develop a fuzzy analytic network process (FANP) model to select the maintenance policy of an acid manufacturing company.

Design/methodology/approach

Four maintenance strategies of Corrective Maintenance (CM), Time-Based Maintenance (TBM), Condition-Based Maintenance (CBM) and Shutdown Maintenance (SM) are investigated to be considered for seven equipment of the case study. These equipment are almost new and include boiler, molten sulfur ponds, cooling towers, absorption tower, converter, sulfur fuel furnace and heat exchanger. Chang’s extended analysis has been employed to deal with fuzzy data and analyze the fuzzy decision matrices. The proposed approach is applied to a sulfuric acid production plant and the suitable maintenance policy is found for all seven equipment of the company.

Findings

Based on the obtained results, the CBM policy is appropriate for high-risk (cooling tower) and high added value equipment (absorption tower). In addition, TBM is selected for boiler and converters while SM is selected for molten sulfur ponds. Finally, high-cost, low-risk and low added value equipment (sulfur fuel furnace and heat exchanger) are more appropriate with CM policy.

Originality/value

This research presents a novel idea to consider cost, risk and added value in the context of maintenance policy selection. From the methodological and theoretical features, this research offers new insights in this area since, to the best of the authors’ knowledge, no comparable study has been conducted before.

Abstract

Purpose

This paper aims to study the hub transportation system in supply chain networks which would contribute to reducing costs and environmental pollution, as well as to economic development and social responsibility. As not all customers tend to buy green products, several customer groups should be considered in terms of need type.

Design/methodology/approach

In this paper, a multi-objective hub location problem is developed for designing a sustainable supply chain network based on customer segmentation. It deals with the aspects of economic (cost reduction), environment (minimizing greenhouse gas emissions by the transport sector) and social responsibility (creating employment and community development). The epsilon-constraint method and augmented epsilon-constraint (AEC) method are used to solve the small-sized instances of this multi-objective problem. Due to the non-deterministic polynomial-time hardness of this problem, two non-dominated sorting genetic algorithm-II (NSGA-II) and multi-objective grey wolf optimizer (MOGWO) metaheuristic algorithms are also applied to tackle the large-sized instances of this problem.

Findings

As expected, the AEC method is able to provide better Pareto solutions according to the goals of the decision-makers. The Taguchi method was used for setting the parameters of the two metaheuristic algorithms. Considering the meaningful difference, the MOGWO algorithm outperforms the NSGA-II algorithm according to the rate of achievement to two objectives simultaneously and the spread of non-dominance solutions indexes. Regarding the other indexes, there was no meaningful difference between the performance of the two algorithms.

Practical implications

The model of this research provides a comprehensive solution for supply chain companies that want to achieve a rational balance between the three aspects of sustainability.

Originality/value

The importance of considering customer diversity on the one hand and saving on hub transportation costs, on the other hand, triggered us to propose a hub location model for designing a sustainable supply chain network based on customer segmentation.

Abstract

Purpose

This study aims to examine the relationship between ethical leadership and project success directly and indirectly through psychological empowerment along with the moderating role of Islamic work ethic.

Design/methodology/approach

Using a time-lagged design, data were gathered from 202 employees working in project-based organizations of Pakistan. Confirmatory factor analysis confirmed the distinctiveness of variables used in the study.

Findings

Consistent with the cognitive evaluation theory, the findings supported the hypotheses other than the moderating role of Islamic work ethics between psychological empowerment and project success. The results confirmed that ethical leadership promotes project success directly and indirectly via psychological empowerment. Furthermore, theoretical and practical implications are also discussed highlighting the importance of ethical leadership for researchers and practitioners.

Originality/value

Literature is insufficient on the topic of ethical leadership in the project management domain with the effect of Islamic work ethics and psychological empowerment. Therefore, the current study explored unanswered research questions in the project management domain.

Abstract

Purpose

This study aims to explore the phenomenon of Islamic religious communication and how Islamic banks in Pakistan use religion-based communication, along with its expected outcomes.

Design/methodology/approach

Transcendental phenomenology approach is opted using a multi-stage data collection strategy consisting of observations, documentary reviews and semi-structural interviews to get deep into the phenomenon in a particular context.

Findings

Findings highlight Islamic religious communication as workplace Islamic da’wah that is majorly categorized into compulsive da’wah, objectics da’wah and impulsive da’wah, serving its role in bringing spirituality to work through work-faith integration.

Research limitations/implications

The finding of the study can be used in planning, formulating and implementing Islamic da’wah-based model to induce spirituality at work.

Originality/value

This study is the first of its type exploring Islamic da’wah in an organizational context as a mean to bring spirituality at work.
