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...

Today supply chains leverage their partner's competencies and in the process also inherit the risks associated with various links of a supply chain. Although it is impossible to completely eliminate various risks, an environment can be created which helps to effectively mitigate risk. The most...
