Abstract: | 本研究提出了一個基於深度優先搜尋演算法的生命週期優化模型,應用於高耗能產品的產品服務化策略評估。該模型能夠在最小化或設定容忍度下的環境影響中找出產品在時間範圍內的循環途徑。模型考慮了空調使用者的主觀持有空調最少時間、安裝空間和空調壽命等三種限制條件,並利用過濾矩陣篩選合理的現況情境進行環境影響評估。本文以台灣大學三間宿舍總計六個空間的分離式冷氣為案例研究,結合建築能源評估模型獲取空間冷負荷條件。案例研究證實,應用產品服務化策略的分離式冷氣在環境效益上優於未實施的情況。此外,在不同的起始保養時間、保養間隔時間、產品原料與製造係數、能效遞減緩解因子和參與對象等變動的多種情境中,研究發現,原料與製造空調的係數變化是系統內總累積環境影響的重要因素,而更多空間參與產品服務化對整體區域的減排效果非常顯著。據我們所知,本研究提出的模型是文獻中首個同時考慮多產品、動態情境變動限制條件和產品服務化策略的環境影響優化與評估的模型。 This study proposes a DFS-Based Spatial Life Cycle Optimization Model (DFS-SLCO) to evaluate product service system (PSS) strategies for energy-using products (EuPs). The model identifies the circular pathways of products within a given time frame while minimizing environmental impact or staying within a set of tolerance. The model considers three constraints: the minimum ownership duration for air conditioner users, installation space, and air conditioner lifespan. It employs a filtering matrix to screen for reasonable current scenarios to evaluate environmental impacts. A case study involving split-type air conditioners in six spaces across three dormitories at National Taiwan University was conducted. The study integrated a building energy assessment model to obtain space cooling load conditions. The case study confirmed that split-type air conditioners applying PSS are more environmentally beneficial than those without it. Additionally, under various scenarios with different initial maintenance times, maintenance intervals, product material and manufacturing coefficients, efficiency degradation mitigation factors, and participants, it was found that changes in the coefficients of material and manufacturing air conditioners are significant factors in the total accumulated environmental impact within the system. Furthermore, increased participation in PSS leads to significant reductions in environmental impact across the entire area. To our best knowledge, the proposed model is the first in the literature to simultaneously consider multiple products, dynamic scenario-based constraints, and the optimization and evaluation of environmental impacts through PSS strategies. |
