Data Envelopment Analysis (Charnes et al, 1978) is a technique used to evaluate the relative efficiency of any process or an organization. The efficiency evaluation is relative, which means it is compared with other processes or organizations. In real life situations different processes or units seldom operate in similar environments. Within a relative efficiency context, if units operating in different environments are compared, the units that operate in less desirable environments are at a disadvantage. In order to ensure that the comparison is fair within the DEA framework, a two-stage framework is presented in this thesis. Fuzzy clustering is used in the first stage to suitably group the units with similar environments. In a subsequent stage, a relative efficiency analysis is performed on these groups. By approaching the problem in this manner the influence of environmental variables on the efficiency analysis is removed. The concept of environmental dependency index is introduced in this thesis. The EDI reflects the extent to which the efficiency behavior of units is due to their environment of operation. The EDI also assists the decision maker to choose appropriate peers to guide the changes that the inefficient units need to make. A more rigorous series of steps to obtain the clustering solution is also presented in a separate chapter (chapter 5). / Master of Science

在今日變動不居的時代，組織面對不確定且快速變遷的環境及需求，在功能、業務及目的方邵不斷更迭變動，因此組織結構亦須隨時因應，適時加以調整。但有時行政機關囿於各項限制因素，無法隨時調整其組織結構，因而使結構無法配合機關功能，形成機關目的達成的阻礙。在此情形下，即有了「畢其功於一役」的重組需求產生。 　　莫雪(F. Mosher)的組織重組定義指：對於組織之落後及不合時代的運作及組織間相互關係，無法以循序漸進的方式予以改變時，所施加的結構性改變。主要包括四大項：1.職位的增加，2.任務的重新安排，3.現職人員的更迭，4.預算的增減。行政機關重組的理論基礎主要建立於四方面：強調理性設計的行政正統論；外在環境影響的環境依賴論；政治互動的政治競爭論及內在價值的核心價值論。這些基礎奠立行政機關重組的各項影響因素，包括重組動力、重組目的、重組步驟、重組策略、重組各項阻礙因素及成功要件。 　　消防機關的重組，在結構方面主要欲設立隸屬於內政部警政署之下的消防署及省級消防廳，縣級消防局等，完整統一的消防體系。由消防機關重組過程可以發現各重組理論基礎的結合應用狀況，及影響因素的互動制衡情形，行政機關及立法機關之間的權力利益交錯更是最重要的要素，研重組策略及成功要件以減少重組過程所可能面臨的阻礙，是行政機關重組成功與否的關鍵。
