Figure 4 Total Cost of Water Arrangement
Since there are so many components of indirect costs, which are often hard to
measure, our model finds two solutions to minimize direct costs and indirect costs
respectively. In our first model, we only minimize the direct cost in our model. In
our second model. since the longer watercourses are, the higher indirect costs will be,
we minimize the length of water transferring, so the indirect cost will be reduced to the
furthest. In both of our models, we solve for the amount of water produced by
desalination and transfered between provinces, the marginal cost of water transfer, the
total length of water transfer and the total direct cost of the project.
