Background: Choosing the most suitable candidate for the position of salesperson is indeed a complex task for managers because several criteria important for the position should be taken into consideration. Such a choice should be considered as a multiple-criteria problem, which can be solved by using the AHP method. Objectives: The main goal is to investigate which criteria are the most import...

Supplier’s Selection is one among the foremost essential activities of supply chain management. Supplier’s Selection could be an advanced activity involving qualitative and quantitative multi-criteria. A trade-off between these tangible and intangible factors is essential in choosing the most effective Supplier.This paper explains the various methodsfor supplier selection and the use of AHP in ...

We consider solutions of the Allen-Cahn equation in the whole Grushin plane and we show that if they are monotone in the vertical direction, then they are stable and they satisfy a good energy estimate. However, they are not necessarily one-dimensional, as a counter-example shows.

This paper is about using intelligent agent technology to facilitate the C2B (Consumer-to-Business) business model on internet. The benefits of C2B, a collective purchasing model, are obvious, but there are some unresolved problems that obstruct the growth of this model. For examples, how to collective individual’s preferences and aggregate to be group’s preferences? What is the mechanism to in...

Those with slightly higher incomes (150 %-300 % FPL) were eligible for exchange-based plans that required cost-sharing and premium payments. M...

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...
