the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

An ACO algorithm for one-dimensional cutting stock problem

The one-dimensional cutting stock problem, has so many applications in lots of industrial processes and during the past few years has attracted so many researchers’ attention all over the world. In this paper a meta-heuristic method based on ACO is presented to solve this problem. In this algorithm, based on designed probabilistic laws, artificial ants do select various cuts and then select the...

Phase diagram of the one-dimensional periodic Anderson model

Phase diagram of the one-dimensional t-J model.

We present an analytic study of the phase diagram of the one-dimensional t − J model and a couple of its cousins. To deal with the interactions induced by the no double occupancy constraints, we introduce a deformation of the Hubbard operators. When the deformation parameter ∆ is small, the induced interactions are softened, accessible by perturbation theory. We combine bososnization with renor...

Developing a Device for Automated Peritoneal Dialysis

Background: Peritoneal dialysis (PD) is an efficient alternative for hemodialysis. Removal of waste metabolites and excess water from the blood circulation are the two main tasks done during dialysis. These are done by using a filter; in PD, the naturally semi-permeable peritoneal membrane acts as the filter. Automated PD machines control intelligently the operations to enhance the efficiency a...
