In this paper, we propose to discuss profitability conditions of a subcontracting constraint for subcontractor companies. The subcontracting imposes unavailability periods of the production unit in order to periodically perform subcontracting tasks (ST). We study the subcontracting constraint...

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...
