since data envelopment analysis (dea) introduced in 1970s, it has been widely applied to measure the efficiency of a wide variety of production and operation systems. recently dea has been extended to examine the efficiency of decision making units (dmus) with two-stage network structures or processes, where the outputs from the first stage are intermediate measures that make up the inputs of t...

In the conventional data envelopment analysis (DEA) internal sub-processes of the production units are ignored. The current paper develops a network-DEA super-efficiency model to compare the performance of efficient network systems. A new ranking method is developed by aggregating the computed super-efficiency scores with a J-divergence measure. The proposed approach is then applied to evaluate...

Researchers studying on adaptation and resilience of systems mainly seek to reduce the vulnerability of extremely complex social-ecological systems against potential changes. Since major portion of natural resources of Iran is interrelated with various users and social groups. Present study focused upon the necessity of studying structural characteristics of social capital of rangeland users in...

Low power wide area networks (LPWANs) are a new generation of wireless communication technology designed for the Internet Things to provide low energy and long range connectivity. LoRa is one promising technology. In this paper, we examine system performance analyze scalability considering packet payload size, spreading factor, number nodes gateways.

Neural network controllers (NNCs) have shown great promise in autonomous and cyber-physical systems. Despite the various verification approaches for neural networks, safety analysis of NNCs remains an open problem. Existing control systems (NNCSs) either can only work on a limited type activation functions, or result non-trivial over-approximation errors with time evolving. This paper proposes ...

This paper is concerned with the consensus tracking problem of high order MIMO nonlinear multi-agent systems. The agents must follow a leader node in presence of unknown dynamics and uncertain external disturbances. The communication network topology of agents is assumed to be a fixed undirected graph. A distributed adaptive control method is proposed to solve the consensus problem utilizing re...
