A smooth dynamic network model for patent collaboration data

چکیده

Abstract The development and application of models, which take the evolution network dynamics into account, are receiving increasing attention. We contribute to this field focus on a profile likelihood approach model time-stamped event data for large-scale dynamic network. investigate collaboration inventors using EU patent data. As we consider submission joint explore driving forces between inventors. propose flexible semiparametric model, includes external internal covariates, where latter built from history.

Revenue - Profit Measurement in Data Envelopment Analysis with Dynamic Network Structures: A Relational Model

The correlated models are introduced in this article regarding revenue efficiency and profit efficiency in dynamic network production systems. The proposed models are not only applicable in measuring efficiency of divisional, periodical and overall efficiencies, but recognizing the exact sources of inefficiency with respect to revenue and profit efficiencies. Two numerical examples, consisting ...

Development of a Hybrid Model for the Evaluation of Sustainable Supply Chains using Dynamic Network Data Envelopment Analysis

Developing realistic models for the evaluation of sustainable supply chains has turned into a major challenge facing managers. The decision-making approaches proposed here consist of two stages. At the first stage, a dynamic-network data envelopment analysis (DNDEA) model is established for the first time, wherein the current efficiency of a business can be influenced by its prior social and en...

A Recurrent Neural Network Model for solving CCR Model in Data Envelopment Analysis

In this paper, we present a recurrent neural network model for solving CCR Model in Data Envelopment Analysis (DEA). The proposed neural network model is derived from an unconstrained minimization problem. In the theoretical aspect, it is shown that the proposed neural network is stable in the sense of Lyapunov and globally convergent to the optimal solution of CCR model. The proposed model has...

Combining time DEA scores using a dynamic panel data model

We define a combined DEA score to evaluate efficiency in agricultural research. The production model we propose considers efficiency measurements under variable returns to scale for each year in the period 2012–2017. We postulate a first-order autoregressive process in the presence of covariates, to explain efficiency. Powers of the autocorrelation coefficient estimated assuming a dynamic panel...
