The analysis of a bi-dimensional dynamic routing model for alternative routing telecommunication networks led to the identification of an instability problem in the synchronous path selection associated with the complex interdependencies among the coefficients of the objective functions and the computed paths for every node pair. In this paper an analytical model enabling to make explicit this ...

There are different decision levels with distinct makers in a decentralized Supply Chain, for example, shippers and carriers. Nevertheless, most studies conducted considering only one decision-making level. The carrier is the agent Dynamic Vehicle Allocation (DVA) problem allocates vehicles to maximize its profit, usually delaying shipping. It necessary respect partnership principle. This paper...

one of the most fundamental components of healthcare system on each country is blood supply chain management. this chain is comprised of two significant components including collecting donor’ bloods and supplying blood’s products. the main purpose of this paper is to concentrate on supplying blood products and present a novel constrained bi-objective mathematical model for a two-echelon blood s...

This paper proposes a method to simplify a computational model from logistic regression for clinical use without computer. The model was built using human interpreted featrues including some BI-RADS standardized features for diagnosing the malignant masses. It was compared with the diagnosis using only assessment categorization from BI-RADS. The research aims at assisting radiologists to diagno...
