National IoMT platform strategy portfolio decision model under the COVID-19 environment: based on the financial and non-financial value view

Abstract

The Internet of Medical Things (IoMT) is an emerging technology in the healthcare revolution which provides real-time healthcare information communication and reasonable medical resource allocation. The COVID-19 pandemic has had a significant effect on people’s lives and has affected healthcare capacities. It is important for integrated IoMT platform development to overcome the global pandemic challenges. This study proposed the national IoMT platform strategy portfolio decision-making model from the non-financial (technology, organization, environment) and financial perspectives. As a solution to the decision problem, initially, the decision-making trial and evaluation laboratory (DEMATEL) technology were employed to capture the cause-effect relationship based on the perspectives and criteria obtained from the insight of an expert team. The analytic network process (ANP) and pairwise comparisons were then used to determine the weights for the strategy. Simultaneously, this study incorporated IoMT platform resource limitations into the zero–one goal programming (ZOGP) method to obtain an optimal portfolio selection for IoMT platform strategy planning. The results showed that the integrated MCDM method produced reasonable results for selecting the most appropriate IoMT platform strategy portfolio when considering resource constraints such as system installation costs, consultant fees, infrastructure costs, reduction of medical staff demand, and improvement rates for diagnosis efficiency. The decision-making model of the IoMT platform in this study was conclusive and significantly compelling to aid government decision makers in concentrating their efforts on planning IoMT strategies in response to various pandemic and medical resource allocations.

Dynamic Optimization for Equity and Dollar Asset: The Case of Japan

“…On the back of financial globalization, there seems to be a growing concern about investments in foreign assets, and indeed, there are many existing studies of asset allocation, including foreign assets (e.g., Jorion, 1992;Jin & Zhang, 2012;Bellalah et al, 2023;Blanchett, 2023;Kim et al, 2023;Yang et al, 2023;Yin & Wong, 2023). However, research on the optimal way to invest in equity and dollar assets in Japan seems to be limited.…”
