模糊综合评价法在养老社区项目社会效益评价中的应用

由于我国人口老龄化形势严峻,传统的养老模式已经受到挑战,养老社区作为结合了家庭养老与社区养老的新型养老模式开始逐渐崭露头角。但目前我国对养老社区项目社会效益评价的指标体系和方法还不成熟,企业往往对养老项目进行财务评价和国民经济评价却忽略了对项目进行社会效益评价,这使得无法充分认识养老社区项目的价值。针对养老社区项目社会效益显著的特点,构建一套能够合理衡量养老社区项目社会效益的指标体系,结合养老社区社会效益评价指标体系和评价模型,以具体的养老社区项目为例,运用模糊综合评价法进行了社会效益综合评价。

Optimal selection of location for Taiwanese hospitals to ensure a competitive advantage by using the analytic hierarchy process and sensitivity analysis

Implementation of the National Health Insurance scheme in Taiwan since 1995 has intensified competition in the local medical sector. Given elevated living standards island wide, Taiwanese residents have become more health conscious and attach increasing importance to quality healthcare, explaining the heightened consumer demand in the quality and scope of medical services. Additionally, the medical service sector has improved its organizational structure and encouraged hospitals to establish management practices that would increase their competitiveness. In such an intensely competitive environment, selecting the optimal location of hospitals to be established is of priority concern. Therefore, this work presents an analytic hierarchy process (AHP)-based evaluation model. Sensitivity analysis is performed in detail by varying the objective factor decision weight, the priority weight of subjective factors and the gain factors. Adopted herein is the renowned diamond model introduced in Porter's The Competitive Advantage of Nations (1990) that influences how competitive advantages, especially with respect to developing and evaluating the objectives of optimal location selection, are related in order to devise a standardized operational procedure. Besides a literature review and interviews with experts, this study also adopts the modified Delphi method, the AHP and the sensitivity analysis to develop an evaluation method for selecting the optimal location of a regional hospital in Taiwan to determine its effectiveness. The proposed evaluation criterion provides a valuable reference for hospital administrators and academics in establishing a standardized means of selecting the optimal location for new medical care facilities.

日本社区嵌入型养老机构规划策略研究及启示

随着我国老龄化的日趋严峻,以及家庭规模日益小型化,子女难以独立完成照顾父母的家庭重任,社区养老的重要性开始突显。通过对日本社区嵌入型养老机构的利用老人进行问卷调研,解析影响老人选择社区嵌入型养老机构的相关因素,提出合理规划社区嵌入型养老机构的规划策略。结果显示老人在选择社区嵌入型养老机构时,重视离自己及子女居住地近的要素,并在实际利用时,呈现相同的趋势;城市化水平不同的城市,其老人在选择利用机构时,选择理由呈现出差异性。当前,我国正处于快速老龄化的发展进程之中,国家高度重视并积极鼓励“在地安养”,探讨日本社区嵌入型养老机构的规划策略,从中汲取经验,对完善中国社区养老机构的规划建设和社区养老服务模式的构建有重要的参考和借鉴意义。     

Decision support for tower crane selection with building information models and genetic algorithms

Tower cranes are major construction equipment that is highly demanded in construction projects. The planning process for tower cranes utilization starts in early stages of the construction projects. Poor selection could incur extra costs on the construction projects or cause delays in project duration. The planning procedures for tower cranes include selection, allocation and operation. This paper presents a framework for the selection of tower cranes types and locations at construction sites. The framework considers three main models: 1) decision making model to select the tower crane type, 2) optimization model for the selection of the ideal number and location of tower cranes, and 3) 4D simulation model to simulate tower crane operations. Several clash detection scenarios are presented to assure the safety operation of the tower crane group. A case study is shown herein to demonstrate the capabilities of the developed framework.     

Contractor selection using the analytic network process

Contractor selection is one of the main activities of clients. Without a proper and accurate method for selecting the most appropriate contractor, the performance of the project will be affected. The multi‐criteria decision‐making (MCDM) is suggested to be a viable method for contractor selection. The analytic hierarchy process (AHP) has been used as a tool for MCDM. However, AHP can only be employed in hierarchical decision models. For complicated decision problems, the analytic network process (ANP) is highly recommended since ANP allows interdependent influences specified in the model. An example is demonstrated to illustrate how this method is conducted, including the formation of supermatrix and the limit matrix.

Underground mining method selection by decision making tools

Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations. In real life, underground mining method selection is one of the multiple attribute decision making (MADM) problems and decision makers have always some difficulties in making the right decision in the multiple criteria environment. Analytic hierarchy process (AHP) and Yager’s methods are the MADM tools and can be used for selection of the best underground mining method by considering the problem criteria. In this study, a computer program (UMMS) based on the AHP and the Yager’s method was developed to analyze the underground mining method selection problems and produce the best underground mining method swiftly for different deposit shapes and ore bodies.     

A total environmental risk assessment model for international hub airports

This paper presents a multi-criteria decision analysis for environmental risk assessment (ERA) with regard to avoiding and eliminating damages and loss under natural disasters in international airport projects. It starts from an assumption that the strategy of eliminating damages and losses under natural disasters is related to the location selection problem, and it is necessary to use the multi-criteria decision analysis for calculated decision-making support. The paper uses the analytic network process (ANP) to demonstrate one of its utility modes in decision-making support to location selection problems, which aims at an evaluation of different projects from different locations. A set of generic criteria for risk assessment at international projects was put forward to support ANP modelling, and it was due to the consideration of social, technical, economic, environmental and political (STEEP) criteria related to the built, social and natural (BSN) trinity environment of international airport projects. At the end, an experimental case study on three international hub airports in China is given to test the ANP model called ERA.Airport, and it is concluded that ANP can be effectively used for risk assessment in the specific utility mode. The ERA.Airport is a generic multi-criteria decision-making model and can be used across the world for accurate environmental risk assessment for international airports.
