演讲内容简介：
Private provision of the highways through the build-operate-transfer (BOT) scheme has become one of the effective ways to expand the city-to-city transportation networks in many countries. This study deals with the practical planning problem regarding how to determine the route locations and toll charges of multi-type vehicles for a new BOT highway in a city-to-city transportation network. A nice formulation based on the binary decision variables is presented to express a feasible BOT rout by making use of the Miller-Trucker-Zemlin (MTZ) technique proposed for the travelling salesman problem. Besides, a uniform distance-based toll charge scheme is selected on this BOT route with multi-type vehicles by assuming that the unit toll charges take the discrete values.
Based on the above problem settings, a bi-level programming model is developed for the proposed problem, where the upper-level model aims to maximize the social network welfare with the project profit constraints while the lower-level model is a conventional multiple-vehicle-type user equilibrium (MUE) problem. A tailed Branch and Cut (BC) relaxation based algorithm are designed for solving the bi-level programming model. In this algorithm, the bi-level programming model is firstly relaxed to a single objective convex programing model by utilizing the tightest convex lower bound of for the bilinear functions, and it is further related to a mixed integer linear programming model. It can be demonstrated that the global optimal solution of the bi-level programming model is guaranteed when the lower bound of the network social welfare of the unexplored solution is not less than the network social welfare of a known MUE solution. Finally, two numerical examples are conducted to assess the efficiency of the models and algorithm proposed by this study.
