Abstract EN
Extreme rainstorm is a main factor to cause urban floods when urban drainage system cannot discharge stormwater successfully.
This paper investigates distribution feature of rainstorms and draining process of urban drainage systems and uses a two-stage single-counter queue method M/M/1→M/D/1 to model urban drainage system.
The model emphasizes randomness of extreme rainstorms, fuzziness of draining process, and construction and operation cost of drainage system.
Its two objectives are total cost of construction and operation and overall sojourn time of stormwater.
An improved genetic algorithm is redesigned to solve this complex nondeterministic problem, which incorporates with stochastic and fuzzy characteristics in whole drainage process.
A numerical example in Shanghai illustrates how to implement the model, and comparisons with alternative algorithms show its performance in computational flexibility and efficiency.
Discussions on sensitivity of four main parameters, that is, quantity of pump stations, drainage pipe diameter, rainstorm precipitation intensity, and confidence levels, are also presented to provide guidance for designing urban drainage system.
