Brownfield redevelopment evaluation based on structure-process-outcome theory and continuous ordered weighted averaging operator-topology method

Abstract

As an important part of urban renewal, brownfield restoration and renovation are of great significance to the sustainable development of cities. The structure-process-outcome theory was introduced into this study to improve the rationality and scientific vigor of the redevelopment assessment process and to evaluate whether brownfield sites meet the conditions for redevelopment. Based on this theory, the relationship among structures, processes and outcomes can be well elucidated. Specifically, a good structure should contribute to an effective process, which will increase the possibility of a favorable outcome. The basic conditions, practice principles, and result orientation in the whole procedure of brownfield redevelopment were comprehensively analyzed. In addition, a more complete and reasonable three-level evaluation index system for brownfield redevelopment was established. In order to reduce the subjectivity in the evaluation process, an unbiased scientific brownfield redevelopment evaluation model was constructed using the continuous ordered weighted averaging operator-topology method. The evaluation decision system was applied to the renovation of a tract project in Chengdu, China. The results proved that the model could effectively and accurately evaluate the quality level of the brownfield redevelopment project, and the proposed recommendations can provide a basis for decision-making.

Beyond the Scalpel: A Tapestry of Surgical Safety, Precision, and Patient Prosperity

“…By engaging in sympathetic communication, surgeons can form a therapeutic relationship with patients, which helps reduce anxiety and enables patients to engage in their healthcare journey actively. Recognizing the significance of the interpersonal bond in healthcare, surgeons prioritizing empathy and communication substantially contribute to their patient's psychological and emotional welfare, ultimately improving their overall well-being [23]. Treatment strategies and concerns for long-term well-being following surgery are essential elements of patient-centered treatment.…”

“…Within the dynamic realm of surgical practice, the constant endeavor for the utmost safety, accuracy, and favorable patient results is characterized by obstacles that stimulate self-reflection and drive the search for enhancement. The present obstacles in attaining these objectives involve complex problems ranging from technology constraints to systemic hindrances and ethical deliberations [23]. As we face these issues, it is crucial to identify possible paths for future research and technological progress while also considering the ethical considerations involved in developing surgical techniques.…”

Innovative Approaches to Safe Surgery: A Narrative Synthesis of Best Practices

“…Facilitating patient involvement in shared decision-making, wherein they actively contribute to conversations regarding treatment alternatives and their consequences, guarantees that their values and preferences are considered during the decision-making process [33]. In addition, patient advocates or navigators can provide supplementary assistance by addressing issues and enhancing communication between patients and healthcare providers [34]. In the end, providing patients with knowledge and involving them actively in their treatment enhances the safety of surgical procedures and fosters a cooperative and trustworthy partnership between healthcare professionals and patients.…”
