in this research work with the aid of tagouchi experimental design and rawing of interaction curves with minitab software, the best rotor speed and dump temperature of mixing for physico-mechanical and rheological properties of the rubber compound with three mixing steps was obtained. moreover by plotting the mean curves in excel worksheet, the dependency of properties on rotor speed, dump temp...

The Tagouchi method was used for providing the instruction of ultra-filter dairy membrane cleaning. The goal function with using of four undimentionalized parameter, i.e., water and milk serum flux, percent of protein and dry mass of permeate, as quality indicator of cleaning of cleaned membrane, was defined. As a result, basic cleaning solution was found as follows: 0.8% NaOH, 1.0% EDTA, 1.0% ...

the organizations use all appropriate tools to improve their service to the customers. the detection of especial customers and the forecast of their behavior undoubtedly can play an important role in improvement of service. in this paper, a new statistical method called the mahalanobis taguchi system has been used for this purpose. this method is used for the analysis of real data of an insuran...

background citric acid is produced in insignificant quantities in iran. despite its great range of utilizations, and from another aspect, high level of production of sugarcane bagasse, the related problems arising from maintenance of this acid require thinking of a measure in the direction of its optimal usage and production. objectives the objective of the present study is to obtain effectual ...
