There are different MCDA methods available. Their numerous nature makes a problem of selection of the best one a very difficult task. There are several approaches which allow to overcome such difficulty. For example, a parallel application of different methods can help a lot to deliver more trustful results of decision analysis. The presented approach applies 4 methods in parallel. All utilised...

We have advanced our previous static theory of polymer entanglement involving an extended Cahn-Hilliard functional, to include time-dependent dynamics. We go beyond the Gaussian approximation, to the one-loop level, to compute the frequency dependent storage and loss moduli of the system. The four parameters in our theory are obtained by fitting to available experimental data on polystyrene mel...

The macroscopic behaviour of air and water in porous media is often approximated using Richards' equation for the fluid saturation and pressure. This equation is parametrized by the hydraulic conductivity and water release curve. In this paper, we use homogenization to derive a general model for saturation and pressure in porous media based on an underlying periodic porous structure. Under an a...

Catering is the act of providing food and services or it may be defined as preparing or providing food for someone else to serve; or preparing, delivering and serving food at the premises of another person or event. The aim of this paper is to provide an analytical tool to select the best catering firm providing the most customer satisfaction. The customers of three Turkish catering firms were ...

We focus on a class of multicriteria methods that are commonly used in environmental decision making--those that employ the weighted linear average algorithm (and this includes the popular analytic hierarchy process (AHP)). While we do not doubt the potential benefits of using formal decision methods of this type, we draw attention to the consequences of not using them well. In particular, we h...

Studying the sustainability of the financial performance of Chinese listed companies is an assessment of their future development capability and a comprehensive evaluation of all aspects of the companies over the past period of time. Based on the financial data of manufacturing industry of Chinese listed companies from 2008 to 2015, this paper uses the AHP (Analytic hierarchy process) method to...
