동적계획법에 의한 우수관망 최적설계에 관한 연구 = A development of optimal design of storm sewer network by dynamic programming

다국어 초록 (Multilingual Abstract)

This study aims at developing simulation model of optimal design condition of urban storm sewer system.
Urban Storm Sewer System Optimal Design Model(USSOD) can compute the pipe capacity, pipe slope, crown elevation, excavation depth, risk and return cost. Rational formula is used for design discharge, Manning's formula for pipe capacity.
Dynamic programming(DP) technique is used for optimization and first order second moment approximation method is used for uncertainty analysis.
Layout design model and optimization model including detention effect in urban sewer system needs in further study.
USSOD is applied to hypothetical drainage basin to test the sensitivity and it proved the more optimal simulation model to a degree, which verifies that USSOD results are more optimal than usual design.
