In recent years, there has been a growing fascination with decentralized systems and self-organizing phenomena. Increasingly, people are choosing decentralized models for the organizations and technologies that they construct in the world, and for the theories that they construct about the world. But even as decentralized ideas spread through the culture, there is a deep-seated resistance to su...

Distributed computing systems can provide benefits not available with centralized computing systems. However, it can be difficult to maintain the security and integrity of data on distributed systems. In fact, some characteristics of distributed data bases give rise to additional security concerns. This article provides a detailed analysis of information security issues in the distributed data ...

In this paper, the common centralized DEA models are extended to the bi-level centralized resource allocation (CRA) models based on revenue efficiency. Based on the Karush–Kuhn–Tucker (KKT) conditions, the bi-level CRA model is reduced to a one-level mathematical program subject to complementarity constraints (MPCC). A recurrent neural network is developed for solving this one-level mathematica...

considered supply chain in this article consists of one vendor and multiple retailers where the vendor applies vendor managed inventory. considering vendor as a leader and retailers as followers, stackelberg game theory is applied for modeling and analyzing this system. a general mixed integer nonlinear model is developed which can optimizes the performance of the system under revenue sharing c...
