整合分散式環境模型於房屋結構之應用

Abstract

整合的工作在土木這個領域中是一件非常困難的事情，以往的做法是將已經程式化的工作連結起來，達到自動化的目的，然而這種做法的缺點在於難與新的工作結合，且表現的效能亦不是令人非常滿意，也會常常出現資料重複等問題。真正的整合是一件龐大且複雜的事情，常常需要將整個結構物做一細小分割，本文利用結構物生命週期（Life Cycle）的觀點，將結構物以生命週期劃分成許多階段，並將結構物視為由許多元件所構成。為了讓元件引用之資料一致，必須建立起結構物的資料庫，而此資料庫亦必須考慮未來擴充的問題，故採用關聯式資料庫，使未來之擴充不會影響既有之整合，並將可同步化的階段同步化，藉以提昇整體效能，且能夠避免資料重複等問題。當結構物的資料有所變更的時候，本文建立的模型會根據變更的資料，自動喚起對應的機制，藉以保持生命週期中各階段結果的正確。此模型採用主從架構模式，具有非常的彈性，可以在分散式的計算環境中運作，亦可在單機中操作。

In the point of the view of structure’s life cycle, design a building structure in civil engineering involves many different sub-tasks during the whole process. Integration of these tasks to an integrated system is very difficult and, in the past, it is simply linking stylized work. The performance, however, isn’t very well and expansion becomes more difficult due to the repetition of the data source probably occurs frequently. During the structure’s life cycle, the design process can be divided into several sequential stages. Meanwhile, the structure will be treated as a combination of several components. Hence, creating a database for the structure to represent these data source is necessary and a feasible approach. The database of the structure must consider the expansion in the future. In this work, an integrated system for design building structures has been developed. The stages of structure analysis and drawing are considered as two sequential processes to demonstrate the feasibility of the model. The model is built on client/server model; that is, the processes are distributed in different platforms that can be connected with local network. The model can automatically synchronize these stages if they can perform simultaneously. The simulation results show that the integrated system can link connected tasks synchronously; initiate corresponding process automatically as it is requested; and perform the whole design task through a network environment.
