Abstract
Aging has become a serious social problem in China. Traditional informal long-term care is hard to sustain because of the reduction in family size and elders’ children migration to big cities. The institution offering services for the disabled elders has been a tendency. There exists a strange phenomenon: some nursing homes are difficult to enter for most disabled elders, while the other ones must search for elders to maintain operation. Therefore, for the evaluation of nursing homes, two problems should be considered: (1) selecting suitable nursing homes for disabled elders; (2) obtaining the key factors influencing the selection of elders and helping nursing homes improve their services based on the key factors. First, we propose a new DEMATEL (Decision-Making Trial and Evaluation Laboratory) method for PLTSs to solve the second problem. Then, we present a novel PROMETHEE (Preference Ranking Organization Methods for Enrichment Evaluations) method to rank the alternatives and make a sensitivity analysis for criteria. Finally, we illustrate our proposed methods to an evaluation problem in Zhenjiang City by a case study. Based on the case study, we can obtain that our proposed methods are effective and practicable.
Highlights
With the development of society and medical level, China is entering an aging society
Traditional informal long-term care may lead to some problems for disabled elders, such as psychological loneliness [2] and reduction in household income [3]. erefore, it is necessary for disabled elders to seek long-term care from nursing homes [4]. ere have been numerous nursing homes in every city. e service levels of different nursing homes are multifarious
(1) How to help disabled elders choose suitable nursing homes? (2) What are the factors of concern for disabled elders and how to improve these factors? For the first problem, we can use a multiple criteria decision-making (MCDM) method to solve
Summary
With the development of society and medical level, China is entering an aging society. In order to address the first key problem, we will propose a new PROMETHEE method to help disabled elders select suitable nursing homes for them. We will propose a new DEMATEL method for PLTS to make an analysis of key factors influencing the evaluation system. (1) Propose a new DEMATEL method for PLTSs by transforming PLTSs into TFNs based on WOWA operators, which will help nursing homes obtain the concern factors of elders and can improve their services precisely (2) Propose a novel PROMETHEE II method for PLTSs, which will help elders select the most suitable nursing homes (3) Propose an approach to sensitivity analysis of criteria weights using a stability interval (WSI) method for PLTSs, which can help DMs find the variation range of criteria weights if the ranking results are stable is paper is organized as follows.
