the integration of an approximate model and a clonal selection algorithm (csa) is considered to one of the most effective ways to solve complex optimization design problems in engineering. in this study, first, a process for developing an approximate model and the principles of clonal selection algorithms were presented. then, a variotherm temperature injection mold used to produce a large liqu...

This paper investigates market integration and asymmetric price transmission in the world rice export markets. Using monthly rice prices from Thailand, Vietnam, and United States, we employ the Johansen test and estimate the threshold vector error correction model (TVECM). Our main findings are that export prices in the three countries are cointegrated, with Thailand and the United States the p...

The Metamodel for Workflow defines the foundations in the area of workflows. It captures the main components of workflow systems and the relationships among them. It is used as a reference model to compare different systems in the context of a tool evaluation. Moreover, it structures the results of workflow methods which are used in the implementation. All these results are conceptual and indep...

The present study aimed to investigate the organic agricultural products supply chain in Iran and provide a processes maturity framework for this chain based on the Iranian Standard of the organic products. Accordingly, the model, proposed in this research, provides an improvement tool that addresses the integration of company's internal processes at low levels, and the integration of the proce...

improving time series forecastingaccuracy is an important yet often difficult task.both theoretical and empirical findings haveindicated that integration of several models is an effectiveway to improve predictive performance, especiallywhen the models in combination are quite different. in this paper,a model of the hybrid artificial neural networks andfuzzy model is proposed for time series for...

The main task of IT-specialists in the last decades was to develop applications supporting different business functions and processes. For today the enterprises are well equipped with IT-devices and applications, but in most cases they run separately in various business units and/or on different platforms, they work with data stored not only redundant but also in other forms. Consequently there...

in this study, the relationship between inflation and economic growth of iran is conciliated with a perspective on uncertainty of inflation. we use a generalized autoregressive conditional heteroskedasticity (garch) model that make possible this advantage that conditional variance of error term changes along the time, also, vector error correction model (vecm) is stable. for surveying the co-in...
