Optimisation of shuttle speed

Instead of optimising the ROI, the shuttle speed can also be optimised. In this case we still optimise the investment but add the shuttle speed to the endogenous variables for both models.

The results of both simulations are given in Table 16.4. [O c_mco-5.xls, c_mco-6.xls]

The results show that optimising the shuttle speed does not yield any important new insights. Furthermore running this simulation with different initial values for the endogenous variables yields different shuttle speeds with
