主講內(nèi)容:
The difficulty in implementation of marginal cost based toll collection is the absence of explicit expression of the demand function. In such circumstances, trial-and-error is usually among the best strategies. We first formulate this problem as a variational inequality problem with partial unknown mappings and then give an efficient implementation scheme. The global convergence of the method is proved and some numerical results are reported to illustrate its performance.
