| 中文摘要: |
| 本文从水库、分蓄洪区及河道调蓄洪的基本原理出发，针对由混联库群和多分蓄洪区组成的复杂防洪系统，研究和建立了一个防洪系统联合运行的大规模线性规划(LP)模型.模型考虑了系统正常行洪与扒口分洪的复杂洪水演进情况，提出了判断扒口分洪界点及其相应的分阶段解算的处理方法，从而形成适用于这一复杂情况的广义化模型.根据模型的超稀疏性等特点，引进多种先进而复杂的数值技术，研制了通用有效的大型计算软件包.实例验算取得了较为满意的成果. |
| 英文摘要: |
| A current large scale LP model is developed for operation of complicated flood control system. For solving forced flood diversion constraints containing 0-1 factor, this paper presents a simplified method-separate-phase algorithm of judging flood diversion point of demarcation. According to super-sparse characteristics of this generalized model, a large common and efficient computational software package is developed. Case study verifies that this model is satisfactory for practical uses. |
