The purpose of this study is to propose a feasible operational evaluation model for property mergers. It is expected that through the merger of enterprises, the comprehensive improvement of business management and the promotion of logistics supply resources will be effectively promoted, so that enterprises can effectively reduce operating costs and achieve maximum profits. This study uses the modified Delphi method and analytic hierarchy process method to find out the key factors of the common dilemmas in Taiwan’s property management companies, and the weight of their impact on the operation. Finally, we use the expected utility theory to develop a valuation model for whether the property is suitable for integration, and to evaluate this, the result is used as a reference indicator for merger operations. After 30 years of vigorous development in Taiwan’s property management companies, due to fierce market competition, most of the companies have reduced their profitability in the face of common dilemmas. The study found that the merger model should be accurately evaluated by the evaluation model. The sharing of logistics resources can indeed bring about the benefits of investment and marketing to the merger, and improve the profitability of the company. At the time of writing, there is no research on such a combined analysis of the property management industry in Taiwan. This research method uses multiple decision analysis theory and utility theory to develop a decision-making model that is suitable for consolidation. It can also be applied to the assessment of mergers in other fields, such as the clean service industry, real estate brokerage and other industry merger assessments. This is also the biggest contribution of this research paper.
