Abstract |
|
|
| Generally, the transportation planning problem involves with facility sitting, roadway selection, distribution route planning
and some related problems, which are optimized based on given network topology. Recently, some of researches noticed that
by changing the network topology, which corresponding to adding a decision whether new roadway construction between nodepairs
in the given transportation network, is often more cost-effective than only sitting new facilities in given networks. Motivated
by aforementioned topology changing result, this paper not only consider about new roadway construction, but also merge the
roadway capacity expansion decision into transportation network design problem. The models generated from an integrated model
for transportation network design and uncapacitated facility location problem. Then we merge the roadway capacity expansion part
and facility capacity decision part into the original model. Mixed integrated programming and network transform mechanism for such
models are proposed. Lastly, we measure the effect of roadway capacity expansion on facility sitting. The numerical testing with
random generated data shows the feasible and effective of models. In conclusion part, the application in real case of proposed models
and algorithms are identified. |
