Abstract
Suggests that the evaluation and selection of potential suppliers is becoming a more important and critical decision in today’s competitive operating environment. Reveals that many firms are reducing their number of suppliers and the supplier base may provide a company with a strategic competitive advantage. Explains that the supplier selection decision now involves many judgemental factors in addition to the historical selection criteria. Offers a prototype expert system which enables users to evaluate and select a potential supplier based on the strategic importance of the product involved, quantitative data and qualitative factors. The system’s early validation results show its potential as an effective decision‐making aid.

Abstract
Purpose
The validity and legitimacy of auditing profession depends on trust as one of the most important assets of auditing profession that trust itself is directly derived from capacity of this profession in responding to responsibilities. The present research has tried to identify 15 ethical values in auditing and analyzing causal relationships of ethical values in auditing from Islam’s perspective using fuzzy decision-making trial and evaluation laboratory (DEMATEL) approach. The purpose of this paper is analyzing causal relationships of ethical values in auditing from Islam’s perspective because ethical values improve auditing and keep the auditor’s independence.
Design/methodology/approach
Reviewing the literature and conducting a survey among 14 certified auditing experts, 15 ethical values in auditing were identified according to Islamic law using fuzzy DEMATEL techniques. Adopting this approach, the study was then to determine causal relationships and to identify influential values.
Findings
Based on the findings, the metrics “independence” with (D−R) = +1.045 was identified to be the cornerstone of the auditing profession. Independence is an essential component for users’ trust in the financial statements. If it is ignored, many other values will further make no sense. Truth-seeking as a value with (D + R) = +3.289 has the greatest interaction with other values, and this reveals that truth-seeking is one of the most significant auditing missions. Additionally, the value “trust” with (D−R) = −1.605 is mostly affected by other variables, suggesting that other values strongly influence this value, and it will be distorted if other values are ignored.
Research limitations/implications
Auditing ethics is one of the most important and striking factors that maintains the credibility and dignity of the auditing profession. Today, the society’s expectations from auditing and accounting professions have increased. Increasing these expectations requires official accountants to provide their professional services in the form of ethical auditing. As this model has been designed using the ideas of the Muslim professional experts, the results may be different from those of non-Muslim professional experts.
Originality/value
Considering that identified values are of great importance in Islam religion, it seems that using Islamic culture and pragmatic tone by professionals, scholars and legislative bodies is necessary to create changes required in the current business culture and as the result to create fundamental changes in professional behaviors of auditing area. This study is the first to provide evidence on the improvement of auditing based on a review of auditing studies in Islam.

Abstract
Purpose
This study systematically explores the patterns and connections in the behavioural bias and investment decisions of the existing literature in the Scopus database published between 2007 and 2022. The purpose of this paper is to address this issue.
Findings
In the article it was determined which contributed documents were the most significant in this particular subject area along with the citations, publications and nations that were associated with them. The bibliographic coupling offered more in-depth insights into the papers by organizing them into distinct groups. The pattern of the publications has been brought to light, and the connection between different types of literature has provided insight into the path that future studies should take.
Research limitations/implications
This study considered only articles from the Scopus database. Future studies can be based on papers that have been published in other databases.
Originality/value
The outcome of this study provides valuable insights into the intellectual structure and biases of investors and adds value to existing knowledge. This review provides a road map for the future trend of research on behavioural bias and investment decisions.

Abstract
Purpose
Globalization of markets and pace of technological change have caused the growing importance of paying attention to supplier selection problem. Therefore, this study aims to choose the best suppliers by providing a mathematical model for the supplier selection problem considering the green factors and stochastic parameters. This paper aims to propose a multi-objective model to identify optimal suppliers for a green supply chain network under uncertainty.
Design/methodology/approach
The objective of this model is to select suppliers considering total cost, total quality parts and total greenhouse gas emissions. Also, uncertainty is tackled by stochastic programming, and the multi-objective model is solved as a single-objective model by the LP-metric method.
Findings
Twelve numerical examples are provided, and a sensitivity analysis is conducted to demonstrate the effectiveness of the developed mathematical model. Results indicate that with increasing market numbers and final product numbers, the total objective function value and run time increase. In case that decision-makers are willing to deal with uncertainty with higher reliability, they should consider whole environmental conditions as input parameters. Therefore, when the number of scenarios increases, the total objective function value increases. Besides, the trade-off between cost function and other objective functions is studied. Also, the benefit of the stochastic programming approach is proved. To show the applicability of the proposed model, different modes are defined and compared with the proposed model, and the results demonstrate that the increasing use of recyclable parts and application of the recycling strategy yield more economic savings and less costs.
Originality/value
This paper aims to present a more comprehensive model based on real-world conditions for the supplier selection problem in green supply chain under uncertainty. In addition to economic issue, environmental issue is considered from different aspects such as selecting the environment-friendly suppliers, purchasing from them and taking the probability of defective finished products and goods from suppliers into account.
