隨著金磚四國的崛起,使得第三世界國家的經濟能力大幅提升,對能源及石化產品的需求也大幅增加,促使全球對能源及石化產業的投資規模加大,加上油價與原物料的飆漲,業主往往要求統包工程,能縮短其工期,以加速獲利。 本研究有別於以往都只探討成本、品質來做改善,而是針對設計初期,佔建廠最重要比例的管線工程設計來著手,因其居核心整合地位,所以優質的管線工程設計往往能夠提升整個工廠的設計品質及降低建造成本。因此本研究應用多屬性決策之灰關聯分析法,配合個案公司的專家問卷,針對其現有的三套3D設計軟體(PDS, PDMS, SP3D)與其評估因子進行評量,期望找出能符合經濟效益、人力需求上最理想化的狀態,提供建廠規劃階段能更為順利,並能兼顧最佳設計品質和成本的下降。 研究的結果顯示,PDMS對於在管線工程設計方面,都比另外兩套3D設計軟體更加合適,本研究結果可提供決策者選擇上之重要依據。
With the rise of the BRIC countries, the Third World countries’ economic capability has growth substantially, and so has their demand on energy and petrochemical products. This prompted an increased scale of global investment into the energy and petrochemical industries. However, the increase in oil and raw material costs often makes proprietors favor turnkey projects to shorten construction time and maximize profit. This study differs from previous approaches where cost and quality were the main focuses, and aims to improve from the piping engineering design, which has core importance in the design stage. A good piping engineering design can usually enhance a plant’s design quality and reduce costs. Hence, this study uses Grey Relational Analysis of Multiple Attribute Decision Making coupled with expert questionnaire to evaluate the three sets of existing 3D design software (PDS, PDMS, SP3D). This study aims to find the most cost and human resource efficient solution for a smooth construction planning that also provide the best design quality under the lowest cost. The study result shows that PDMS is more suitable for the above purposes than the other two sets of 3D design software, and the conclusion of this study should provide an important reference for decision makers.
