In this paper, a two stages method to determine suitable benchmark and return scale of the decision making units set is presented. At first, all of the efficient reference set in no radial data envelopment analysis (DEA) based on linear programming is found. first, RAM model is introduced and units is investigated using this model, then, to run the given algorithm below steps is performed. At t...

With electronic auctions gaining importance, economists have increasingly gotten interested in researching the impact of variations in auction protocols. However, the infinite number of possible auction configurations and the significance of details make this a hard and tedious task. Therefore we address the issue of comprehensive description both from a conceptual and an implementation perspec...

Checklists are cognitive tools that ensure quality, safety and reduce human errors when executing working routines. Besides their popularity in practice, checklists increasingly receive attention from academics, who have even called for a “science of checklists”. According to prior studies, mobile checklists are more effective than their paper-based alternatives, but research in this domain is ...

This paper presents a practical implementation for a new formula of nonlinear PID (NPID) control. The purpose of the controller is to accurately trace a preselected position reference of one stage servomechanism system. The possibility of developing a transfer function model for experimental setup is elusive because of the lack of system data. So, the identified model has been developed via gat...

in this study, climatic parameters are used to evaluate the sensitivity of reference evapotranspiration in isfahan and rasht with two semi-arid and moderate climates using two intelligent methods during 1970-2010. in this research, multi-layer precpetron e (mlp) and gene expression programming (gep) intelligent models are used in order to analyze the sensitivity of reference evapotranspiration ...

A “learning system” possesses the capability to improve its performance over time by interaction with its environment. A learning control system is designed so that its “learning controller” has the ability to improve the performance of the closed-loop system by generating command inputs to the plant and utilizing feedback information from the plant. In this brief paper, we introduce a learning...

In this paper, we introduce a Spatial Sensor Web reference model. Firstly, we present the concept of the Sensor Web and the Spatial Sensor Web. Then we use a layered conceptual model to describe the Sensor Web. Thirdly, we present the Spatial Sensor Web reference model. The reference model is composed by seven logical layers. It provides an architectural framework for constructing a Spatial Sen...

In this paper we introduce and explore an extension to the existing paradigm of model transformation. Specifically, we extend existing model transformation approaches by considering reference models and human input as important sources for and during model transformation. To cater for this new type of model transformation, we develop an approach grounded on a common generic model and a series o...

In this paper we present the model-checking module of decision-making models in the frame of ModelsCreator, an educational modelling environment. The model-checking module aims to assist young students to construct qualitative models for decision-making problems solving. We specify the decision-making models that may be built and we explain the model checking mechanism. The model-checking mecha...
