Abstract:	研究目的：建築業在充滿活力、競爭以及變動的環境中運營，在索馬里蘭表現不佳，關鍵成功因素有助於組織機構制定短期與長期策略，然而，在不確定環境下，關鍵因素的層次關係，在文獻中尚未經過徹底研究，本論文目的是對於索馬里蘭建築項目各個獨立的關鍵成功因素，進行確認、分級並檢查。研究設計、方法、途徑：在本研究中，決策者的因素和語言偏好之間的等級關係，考慮使用模糊層級分析法(Fuzzy AHP)及模糊決策實驗室分析法(Fuzzy DEMATEL)，從文獻中確定了五個關鍵因素以及四十個子因素。應用模糊層級分析法對每個因素和子因素的相對權重進行排序，模糊決策實驗室分析法(Fuzzy DEMATEL)用於發現因素之間的相互關係。調查所用的問題由一組決策者回答，他們由至少具有十年經驗的資深專業建築界人士組成。研究結果：根據以模糊層級分析法對相關重要性的分析，發現最主要的關鍵成功因素群集，是工程師相關因素及承包商相關因素，例如與客戶、業主、顧問及設計師的關係，承包商高層管理人員的支持以及承包商的經濟和財務狀況。模糊決策實驗室分析法的結果表明，影響最大的群體因素是外部環境因素和項目相關因素。研究意義：研究結果為決策者和項目經理提供了影響他們的績效與進步，重要並具有影響力的因素的意識，並使他們能夠在結構上規劃並分配項目資源。研究侷限性：本研究僅限於索馬里蘭建築業的現狀，以及為此一現狀選定的變因和使用的研究方法，因此如果其中一個面向發生變化，研究結果可能會發生顯著改變。 Purpose: The construction industry is operating in a dynamic, competitive, and uncertain environment and it is underperforming in Somaliland. The critical success factors (CSFs) approach helps organizations to successfully implement short term operational plans and long term strategic plans. However, the hierarchical relationship of the CSFs under uncertainty has not thoroughly investigated in the literature. The purpose of this study is to identify, rank and examine the interrelationship of CSFs for construction projects in Somaliland. Design/Methodology/Approach: In this study, a hierarchical relationship between factors and linguistic preferences of decision-makers is considered using fuzzy AHP and fuzzy DEMATEL. Five critical factors and forty subfactors are identified from the literature. The fuzzy AHP method is applied to rank the relative weight of each factor and subfactors. While fuzzy DEMATEL is used to discover the interrelationship among the factors. The questionnaire questions were answered by a group of decision-makers composed of senior construction professionals with a minimum of 10 years of experience. Findings: According to the fuzzy AHP analysis of relative importance it was found out that the top CSF groups are relationship engineering factors and contractors related factors, such as the relationship with clients or owners and consultants and designers, contractors top management support and economic and financial situation of the contractor. While the results of fuzzy DEMATEL indicate that the most influential group factors are external environment factors and project-related factors. Research Implications: The study findings provide top managers and project manager’s awareness about the important and influential factors that affect their performance and progress and it will enable them to structurally plan and allocate project resources. Research Limitations: This study is limited to the current situation of the Somaliland construction industry, the selected factors, the methods used, hence the findings can change significantly if one of those limits are changed.
