This paper considers the dynamics of edges in a network. The Dynamic Bond Percolation (DBP) process models, through stochastic local rules, the dependence of an edge (a, b) in a network on the states of its neighboring edges. Unlike previous models, DBP does not assume statistical independence between different edges. In applications, this means for example that failures of transmission lines i...
data envelopment analysis (dea) measures the relative efficiency of decision making units (dmus) with multiple inputs and multiple outputs. dea-based malmquist productivity index measures the productivity change over time. we propose a dynamic dea model involving network structure in each period within the framework a dea. we have previously published the network dea (ndea) and the dynamic dea ...
رویکرد این پژوهش ترکیبی از مراحل مختلف فرایند انتقال تکنولوژی است، که با تمرکز بیشتر در مراحل انتخاب روش انتقال و بومی سازی و جذب یک تکنولوژی، یک مسیر مناسب را با هدف ارتقا سطح فنی جهت جذب تکنولوژی وارداتی پیشنهاد می دهد. با توجه به نوع مساله پیش رو در این پژوهش که نوعی تصمیم گیری چند معیاره می باشد، برای تجزیه و تحلیل نتایج حاصل از مصاحبه با متخصصین و پرسشنامه های تکمیل شده و به دلیل ارتباط تع...
An adaptive version of growing and pruning RBF neural network has been used to predict the system output and implement Linear Model-Based Predictive Controller (LMPC) and Non-linear Model-based Predictive Controller (NMPC) strategies. A radial-basis neural network with growing and pruning capabilities is introduced to carry out on-line model identification.An Unscented Kal...
This study presents a strategic viewpoint of the dynamic growth pattern of Iran’s share in regional natural gas trade, through factor prioritization, using network analysis. The study is an exploratory one, which falls under the cross-sectional category based on its research method and time frame for gathering pertinent data. This study has been conducted over the period 2019 to 2020. The main ...
In this paper, multi-class dynamic PERT network is considered as a queueing network, where the projects are similar and new projects are generated according to a Poisson process. Each activity is performed independently in its corresponding service station with exponential distribution by one server from several servers settled in service station based on FCFS (Fist Come, First Served) discipli...
this paper deals with the problem of optimizing two-stage structure decision making units (dmus) where the activity and the performance of two-stage dmu in one period effect on its efficiency in the next period. to evaluate such systems the effect of activities in one period on ones in the next term must be considered. to do so, we propose a dynamic dea approach to measure the performance of su...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
