The assembly precision of the magnetic system an electromechanical meter is important guarantee for measurement accuracy meter. large gap between two poles key point that affects and also difficulty manufacturers face. In this paper, controllable factors affect a are selected by performing orthogonal experiment, process analyzed, noise selected; design achieved using inner outer array used to e...

index tracking is the process of developing a portfolio that reproduces the performance of an index. the tracker portfolio has relatively good diversity and low turnover and low transaction costs. in this paper we applied a binary programming model for index tracking problem. in this model the number of assets for portfolio construction is defined by portfolio manager. the robust optimization f...

The development of complex products with high quality in dynamic markets requires appropriate robust design and tolerancing workflows supporting the entire product process. Despite large number methods tools available for designers tolerance engineers, there are hardly any consistent approaches that applicable throughout all stages. This is mainly due to break between primarily qualitative conc...
