Auditing with technology: using generalized audit software in the classroom

Over the past decade, improvements in generalized audit software have created a situation in which auditing “through” the computer may be both more effective and more efficient than in the past. This paper describes a series of assignments that allow an instructor to bring a meaningful application of generalized audit software to the undergraduate auditing classroom. The assignments we have developed are meant to supplement traditional audit coursework by providing students an experience of applying audit procedures electronically.     

A combination of QFD and imprecise DEA with enhanced Russell graph measure: A case study in healthcare

Quality function deployment (QFD) is a proven tool for process and product development, which translates the voice of customer (VoC) into engineering characteristics (EC), and prioritizes the ECs, in terms of customer's requirements. Traditionally, QFD rates the design requirements (DRs) with respect to customer needs, and aggregates the ratings to get relative importance scores of DRs. An increasing number of studies stress on the need to incorporate additional factors, such as cost and environmental impact, while calculating the relative importance of DRs. However, there is a paucity of methodologies for deriving the relative importance of DRs when several additional factors are considered. Ramanathan and Yunfeng [43] proved that the relative importance values computed by data envelopment analysis (DEA) coincide with traditional QFD calculations when only the ratings of DRs with respect to customer needs are considered, and only one additional factor, namely cost, is considered. Also, Kamvysi et al. [27] discussed the combination of QFD with analytic hierarchy process–analytic network process (AHP–ANP) and DEAHP–DEANP methodologies to prioritize selection criteria in a service context. The objective of this paper is to propose a QFD–imprecise enhanced Russell graph measure (QFD–IERGM) for incorporating the criteria such as cost of services and implementation easiness in QFD. Proposed model is applied in an Iranian hospital.     

An application of IDEA to wheat farming efficiency

Data Envelopment Analysis (DEA) is a nonparametric approach to evaluating the relative efficiency of decision making units (DMUs) that use multiple inputs to produce multiple outputs. An assumption underlying DEA is that all the data assume the form of specific numerical values. In some applications, however, the data may be imprecise. That is, all the input and output data cannot be exactly obtained due to the existence of uncertainty. They are only known to lie within specified intervals. A DEA model with imprecise data or, more compactly, an Imprecise DEA (IDEA) model proposed in this article to evaluate efficiency for each DMU. The article is illustrated with an application to Iranian wheat producer provinces.
