摘要

過往的研究將要徑空間定義為施工空間中沒有寬裕空間，本研究則修正為在此空間內不允許施工或動線衝突之發生，因衝突發生必會造成生產力折損。此定義對施工管理更有助益，因過往的定義不一定會造成生產力折損，而本研究的目的即在利用空間邏輯特性找出要徑空間避免施工或動線衝突發生造成生產力折減。本研究擬定五個空間變數，包含空間語法指標（相對便捷值、相對控制值）以及本研究依施工空間特性所提出的空間變數（單元阻塞率、垂直動線流量以及出口動線流量），將其導入DEA-DA模型以判別可能的要徑空間，並結合多目標決策TOPSIS排序法從其中找出最重要之要徑空間。研究結果發現三種不同分析方法中，唯DEA-DA結合TOPSIS的方法判別相關性超過80%。

Critical Space had been defined as its slack space is equal to zero. This Study offers the further and improved following definition of critical space: ＂Critical Space is in whom conflicts aren't allowed to occur due to significant productivity loss once occurred.＂ The definition is more accurate and helpful to construction management. The space with zero slack space doesn't necessarily cause productivity loss. The purpose of this study is to calculate and find the critical space by using logics of space structures then to avoid conflicts occurred in critical space. The quantitative parameters including integration value and control value derived form Space Syntax and other three parameters including unit blocking rate, vertical direction flow and exit direction flow derived form identities form building construction can be used to the DEA-DA with TOPSIS model to predict critical space. DEA-DA can be modeled to predict financial crisis of construction companies and TOPSIS is a multi-criteria decision analysis method for finding ideal solutions. Among three prediction models featuring in this study, only DEA-EA model with TOPSIS method can be defined highly correlated as correlation coefficient of it is larger than 0.8.
