In this research, we study at which speeds an oceangoing ship should ideally travel on each of a series legs journey as to maximise the Net Present Value (NPV) ship. A novel class models for speed optimisation problem, refer P(n,m,Go), is presented. It based incorporating cash-flow functions and flexible in modelling structures variable composition. By studying properties optimal leg within NPV...

The assumption of expected profit-maximizing bidding behavior in a multi-unit, multi-period auction with step-function supply curves is used to estimate cost functions for electricity generation units and derive tests of expected profit-maximizing behavior. Applying these techniques to data from the National Electricity Market in Australia reveals statistically significant evidence of output-de...
