Fuzzy linear regression and its applications to forecasting in uncertain environment

摘要: Abstract Linear regression has been used for many years in developing mathematical models application marketing, management, and sales forecasting. In this paper, two different forecasting techniques are discussed. The first technique involves non-fuzzy abstract methods of linear econometrics. A study the international market cameras, done 1968 by John Scott Armstrong, utilized these techniques. second uses fuzzy introduced H. Tanaka, S. Uejima, K. Asai, 1980. a computer peripheral equipment United States is discussed using regression. Moreover, applied to an uncertain environment.
