the aim of this paper is to present the prediction model of the transport energy demand in iran. markov chain grey model (mcgm) is proposed to forecast the transport energy demand of iran. then it is compared with grey model (gm) and regression model. moreover, the mcgm forecasting model is used to forecast the annual gasoline demand of iran up to the year 1400. the aim of this paper is to pres...
Purpose – The relationship between energy consumption (EC) and economic growth is a well-known and more studied subject in literature. In this study, Turkey’s EC and gross domestic product (GDP) relation is analyzed. The aim of this study is to find out the relative importance of energy components on GDP for Turkey. Hence, the authors can make some strategic implications up to the importance of...
According to the urban logistics green degree’s evaluation, a weighted grey correlation analysis method based on the analytic hierarchy process is proposed to determine the weight of each index in the urban logistics green degree evaluation system, and then figure out the optimal relative degree, realizing the green degree of each urban logistics. Finally, an example was given for proving the e...
The performance assessment of professional baseball starting pitchers is considered a multi-attribute decisionmaking (MADM) problem. This study develops an evaluation model based on the analytic hierarchy process (AHP) and grey relational analysis (GRA) to evaluate starting pitcher performance for teams of the Chinese Professional Baseball League. The AHP is used to determine attribute weights,...
The aim of this paper is to investigate the multiple attribute decision making problems with intuitionistic fuzzy information, in which the information about attribute weights is incompletely known, and the attribute values take the form of intuitionistic fuzzy numbers. In order to get the weight vector of the attribute, we establish an optimization model based on the basic ideal of traditional...
post-harvest losses particularly due to fungal invasions, is a major factor in limiting the shelf life of many fruits and vegetables. in order to study the effects of essential oils of thyme (thymus kotschyanus), basil (ocimum basilicum) and rosemary (rosmarinus officinalis) on control of grey mold (botrytis cinerea) disease in pear, a series of in vitro and in vivo (during cold storage of pear...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
In this paper, we propose a computational approach to modeling the Zone of Proximal Development of students who learn using a natural-language tutoring system for physics. We employ a student model to predict students’ performance based on their prior knowledge and activity when using a dialogue tutor to practice with conceptual, reflection questions about high-school level physics. Furthermore...
Adaptable design is a new design paradigm to create designs and products that can be easily changed to satisfy different requirements. Adaptable design aims at identifying the designs and products considering functionality, manufacturing efforts, customization, and environment friendliness. This research focuses on adaptable design considering product adaptability. In this work, product adaptab...
