摘要

本研究應用ZeroC 公司開發之Ice (Internet Communications Engine)中介軟體(Middleware)為計算平台，進行雨水下水道水理模擬，探討分散式雨水下水道模擬的可行性。研究中整合SWMM(Storm Water Management Model)之地表逕流模式(SWMM-RUNOFF)與雨水下水道模式(SWMM-EXTRAN)，研發分散式雨水下水道模擬系統（Ice Distributed Simulation Sewer System，簡稱IDSS）。利用ZeroC 之物件導向(object-oriented)中介軟體提供之介面(interface)降低分散式系統開發，訊息傳遞及資料交換之複雜性。以台北市第四排水分區之保儀、實踐及中港抽水站系統為案例配合四種情境，測試IDSS 之效能，模擬分析結果證實分散式雨水下水道模擬的可行性。同時IDSS 系統利用分散式運算架構於此研究案例中節省20%運算時間，可提升雨水下水道水理模擬演算效能。

This study applies the Ice (Internet Communications Engine) middleware technology from ZeroC Company as a distributed computing platform to simulate storm sewer system and discuss the feasibility about building a distributed storm sewer simulation system. An Ice distributed simulation sewer system (IDSS) is developed by integrating the RUNOFF and EXTRAN modules of the SWMM (Storm Water Management Model) model. In order to reduce the complexity of information exchange and message passing of distributed system developments, IDSS uses the object-oriented middleware interface developed by zeroC. The Bao-yi, Shi-Jian and Zhung-Gung drainage systems located within the 4th drainage district of Taipei City are tested with four scenarios to investigate the performance of the IDSS. The simulated results show that the proposed approach is feasible. Simultaneously, the IDSS system not only gives identical simulation performance, but also saves 20% computation time and speeds up the efficiency of storm sewer simulation.
