A Multicriteria Decision-making Approach to Create Accessible Environments to Empower Mobility-impaired Individuals

Abstract

Individuals with mobility disabilities can experience numerous health advantages when connecting with nature in various ways, such as passive enjoyment, active participation, or rehabilitative programs. These benefits encompass physical and mental benefits, as well as social gains. However, a range of concerns related to making natural environments accessible to and usable by people with mobility impairments demand the attention of various professionals, including caregivers, landscape architects, rehabilitation therapists, and policymakers. Efforts to promote inclusivity and accessibility aim to remove barriers and create environments where individuals with disabilities can participate fully in education, employment, public life, and social activities. This may involve adapting physical spaces, promoting awareness, providing assistive technology, offering support services, and understanding of disability issues. To enhance the accessibility of public places for disabled people, we must consider multiple criteria and risks. In this article, to address such issues we develop three multicriteria decision-making (MCDM) approaches based on picture cubic fuzzy information. Since aggregation operators (AOPs) play a crucial role in decision-making, we present the aggregation proficiency for picture cubic fuzzy information and develop a series of AOPs, such as picture cubic fuzzy Hamacher order weighted averaging (PCFHOWA), picture cubic fuzzy Hamacher weighted averaging (PCFHWA), picture cubic fuzzy Hamacher hybrid averaging (PCFHHA) operators and present some essential properties of these Opts. After studying their fundamental operations and properties, we utilize these operators to develop multicriteria decision making (MCDM) model with picture cubic fuzzy information. We present the extended TOPSIS method and extended VIKOR mothod for MCDM problems. We present a numerical example related to improving accessibility for disabled people in a public park. The results explore the effectiveness of our proposed methodologies and provide accurate measures to address the uncertainty related to the accessibility of disabled people to public places.
