A Fuzzy Logic Approach to Assessing Materiality
نویسنده
چکیده
Auditors may encounter misstatements during the course of an audit, each of which requires a binary materiality assessment. We propose a fuzzy expert system approach that assesses materiality as a continuous characteristic by allowing a misstatement to possess a degree of materiality between 0 and 1. This potentially allows the auditor more flexibility and precision in materiality assessment, and greater insight regarding subsequent testing and investigation. We demonstrate that a fuzzy expert system can help the auditor incorporate qualitative factors into the materiality assessment of each misstatement and identify which misstatements are most worthy of further investigation. The auditor may compare the materiality assessments of all misstatements to plan an audit strategy. By providing a formal model structure, the fuzzy expert system formalizes and documents the materiality assessment process. This may facilitate better communication within the audit team and with the client, and enhances process consistency across auditors, engagements, and years.

Assessing process performance with incapability index based on fuzzy critical value
Process capability indices are considered as an important concept in statistical quality control. They have been widely used in the manufacturing industry to provide numerical measures on process performance. Moreover, some incapability indices have been introduced to account the process performance. In this paper, we focus on the one proposed by Chen ~cite{Che:Stat}. In today's modern world, a...

متن کاملA FUZZY MODEL FOR ASSESSMENT PROCESSES
The methods of assessing the individuals’ performance usually applied in practice are based on principles of the bivalent logic (yes-no). However, fuzzy logic, due to its nature of including multiple values, offers a wider and richer field of resources for this purpose. In this paper we use principles of fuzzy logic in developing a new method for assessing the performance of groups of individua...
متن کاملMulti-objective design of fuzzy logic controller in supply chain
Unlike commonly used methods, in this paper, we have introduced a new approach for designing fuzzy controllers. In this approach, we have simultaneously optimized both objective functions of a supply chain over a two-dimensional space. Then, we have obtained a spectrum of optimized points, each of which represents a set of optimal parameters which can be chosen by the manager ...
