The setting of time standards by work measurement is costly and consumes much time and effort. Therefore, the aims are to minimise time measurements while guaranteeing that the measurements are sufficient to provide a required statistical precision. This paper presents two methods for...

In this study, we use zero-one variables to control fixed transaction costs independent of trade size in the portfolio selection problem. The optimal solution to the maximum flow, risk constrained stochastic portfolio network is found using Digital Portfolio Theory (DPT). Digital signals...
