Although banking has been widely studied using standard DEA (Data Envelopment Analysis) models and its variations, these models do not in fact account for the internal structure relative to measures characterizing banking operations performance. In this paper, efficiency in Brazilian banking is measured using a two-stage process. In the first stage, called cost efficiency, number of branches an...

This tutorial provides a step-by-step guide to performing cost-effectiveness analysis using a multi-state modeling approach. Alongside the tutorial, we provide easy-to-use functions in the statistics package R. We argue that this multi-state modeling approach using a package such as R has advantages over approaches where models are built in a spreadsheet package. In particular, using a syntax-b...

In this paper, we consider fuzzy inventory with backorder. First, we fuzzify the storing cost a, backorder cost b, cost of placing an order c, total demand r, order quantity q, and shortage quantity s as the triangular fuzzy numbers in the total cost. From these, we can obtain the fuzzy total cost. Using the signed distance method to defuzzify, we get the estimate of the total cost in the fuzzy...

bstract: The paper analyzes the efficiency and productivity of the Romanian banks from 2006-08. It uses a non-parametric approach, the data envelopment analysis (DEA) to analyze banks’ efficiency. Based on a sample of 15 commercial banks, our findings reveal that although the efficiency of the Romanian commercial banks improved since 2006, the cost efficiency scores are relatively low. Also, ev...

The literature analysing efficiency of financial institutions has enveloped rapidly over the last years. Most studies have focused on the input side analysing input technical and cost efficiency. Only few studies have examined the output side evaluating output technical and revenue efficiency. We know that both sides are relevant when evaluating efficiency of financial institutions. Therefore t...

Health care cost-effectiveness analysis (CEA) often uses individual patient data (IPD) from multinational randomized controlled trials. Although designed to account for between-patient sampling variability in the clinical and economic data, standard analytical approaches to CEA ignore the presence of between-location variability in the study results. This is a restrictive limitation given that ...

steel production in iran has been recorded since fourteen century b.c. however the main growth and development in steel industry has occurred in recent decades. steel industry has important role in development of industrial countries, and also steel consumption may consider as an important ind ices in the development process. this pap er has analyzed two main complexes (zobe ahan and mobarakch)...
