Traditionally most cross-selling models in retail banking use demographics information and interactions with marketing as input to statistical models or machine learning algorithms to predict whether a customer is willing to purchase a given financial product or not. We overcome with such limitation by building several models that also use several...

Purpose The purpose of the paper is to develop an integrated framework for performance management of healthcare services. Design/methodology/approach This study develops a performance management framework for healthcare services using a combined analytic hierarchy process (AHP) and logical framework (LOGFRAME). The framework is then applied to the...

This chapter deals with the measurement of efficiency through the nonparametric, mathematical programming-based technique better known as data envelopment analysis (DEA). A producer is defined as an economic agent that takes a set of inputs and transforms them either in form or in location into a set of outputs. In DEA, the economic agent is referr...

We propose a new mathematical model for efficiency analysis, which combines DEA methodology with an old idea—Ratio Analysis. Our model, called DEA-R, treats all possible ratios “output/input” as outputs within the standard DEA model. Although DEA and DEA-R generate different summary measures for efficiency, the two measures are comparable. Our math...

This paper presents a general methodology for numerical evaluation of complex qualitative criteria based on the theory of fuzzy sets. A special emphasis is given to the criteria frequently used in water resources decision making. Water resources’ qualitative criteria are exhibiting a high level of complexity that does not allow for an easy and reli...
