This paper studies a single-stage production system, two-stage production system where specification limits are designed for inspection. When quality characteristics fall below a lower threshold or above an upper threshold, a decision is made to rework or scrap the item. The target is to determine the optimum target for a process based on rework or scrap costs. In contrast to previous studies, ...

the ahp/dea methodology is an integration of analytical hierarchical process (ahp) and data envelopment analysis. this method uses the capabilities of both ahp and dea. however, it has some problems: it illogically compares two decision-making units in a data envelopment analysis (dea) model, it is not compatible with dea ranking in the case of multiple inputs/multiple outputs, and it leads to ...

many studies have been conducted to determine the efficiency of two-stage network structures in the recent years. the two-stage network with additional inputs to the second stage, in which the second stage is independent of the first stage are one of these structures. thus, there is a need for a model capable of calculating the efficiency of two-stage structures as well as efficiency of each st...

Evidence-based BPM has gained significant momentum in recent years, thanks to the widespread adoption of enterprise systems that store detailed business process execution data in event logs. Techniques for analyzing business processes using event logs are termed “process mining” techniques. Their objective is to aid business analysts in improving business processes by learning knowledge from ma...

The purpose of this paper is to develop an output oriented methodology for calculating productivity growth by using Malmquist productivity index (MPI) and two different data envelopment analysis (DEA) views (optimistic and pessimistic) simultaneously, and apply it to five Iranian Commercial Banks over the four time period (2009-2013). Consequently, we have proposed a new approach called the dou...

On the road to carbon neutrality, a great deal of attention is being paid emerging technologies such as DRI (direct reduced iron) process. This study proposes two-stage process using reformed COG (coke oven gas), and determined optimal parameters. The reduction carbonization Carajás iron ore used in field were examined by monitoring weight loss samples, EDS XRD measurements with respect reactio...
