“…It is often the deadline of the construction period. During the construction process, it is necessary to ensure the normal work, study, and life of school teachers and students, so that the control of the construction period and environmental safety and hygiene are placed in a more important position [27]. e weight of subcontracting coordination is about 17%, only second after checking the construction period.…”

Gray system theory is a new field of control theory, which is the product of applying cybernetics and methods to social and economic systems, and is also the product of the combination of control theory and operations research. It takes the gray system as the research object. Whitening, desalination, quantification, modeling, and optimization are the core of the gray system, and it aims to predict and control the development of various gray systems. The purpose of this paper is to study how to analyze and study the impact of higher education cooperation projects with the help of multi-dimensional gray theory and describe the gray system theory. The problem of analyzing the impact of cooperation projects proposed in this paper is based on the gray theory, so it is elaborated around its concept and related algorithms, and a case design and analysis of the impact of higher education cooperation projects are carried out. The experimental results show that the institutions responsible for infrastructure at the top of the school have the greatest impact on infrastructure projects, accounting for about 70%, with 20% weight for communication with government agencies, and about 10% for communication with users.

“…Methods included in the GST are widely used in practice, especially when information uncertainty manifests in the form of a small set of data (which renders it impossible to use statistical methods-e.g., with respect to short time periods), incomplete information or information burdened with inaccuracy or subjectivity [29]. The described application area of methods included in Grey System Theory spurred their growing popularity [30]. In recent years, using a number of grey models, the uncertainty within grey systems with economic, social, technical or even natural character has been modeled [31,32].…”

“…Among grey system models there are, e.g., grey prediction models, grey decision-making models, grey control models, and grey relations models [37]. The selected methods of information uncertainty modeling are included in Grey System Theory, when one of the three constructs is used in them-grey numbers, whitenization function, or distributed grey [30].…”

In the paper, a new indicator exemplifying the conversion efficiency of expenditures towards economic growth into results pertaining to sustainable development, dubbed the “Synthetic Efficiency Indicator for Economic Growth” (hereinafter: “SEI-EG”) has been proposed. The inspiration for proposing such an indicator was the identification of the lack of connections between research on economic convergence and the research area connected with sustainable growth category. It was assumed that, in the first place, outcomes of the proposed convergence will be visible in developed economies, represented by EU15 member states. The set goal was to provide an answer to the question of difference between EU15 member states with respect to efficiency of converging expenditures exemplifying economic growth into results pertaining to sustainable growth. The research was conducted for 2016–2018 using Grey System Theory. With the use of the elaborated indicator, the authors created a ranking list of countries based on the efficiency of economic growth towards sustainable growth criterion. The conducted research proved that, in general, the smaller EU member states are characterized by significantly higher efficiency of converging expenditures exemplifying economic growth into results pertaining to sustainable development in the researched area. Among the countries with large economies, only Germany showed efficiency comparable to smaller ones.

“…Oz et al 33 suggested an integrated risk assessment model based on Pythagorean fuzzy sets and the technique for order preference by similarity to ideal solution (TOPSIS) for examining the occupational hazards of a natural gas pipeline project. Based on grey system theory, Nowak et al 34 proposed a grey occupational risk assessment model for evaluating the risks of mechanics who are working in a manufacturing enterprise. Liu et al 2 introduced a hybrid OHS risk assessment model by integrating picture fuzzy sets and alternative queuing method to analyze the risk of occupational hazards in construction sites.…”

Occupational health and safety (OHS) is a multidisciplinary activity aimed at recognizing, evaluating and controlling hazards arising in or from the workplace that could impair the health and well‐being of workers. In dealing with an OHS risk analysis problem, it is a crucial step and also a big challenge to assess the risk of occupational hazards. Normally, domain experts tend to use qualitative words to express the risk of occupational hazards due to the fuzziness of human cognition, and multiple risk criteria are often involved in the OHS risk analysis. In this study, we develop a new OHS risk assessment framework by integrating the TODIM (an acronym in Portuguese for interactive and multicriteria decision‐making) and preference ranking organization method for enrichment evaluations (PROMETHEE) methods to assess and rank the risk of occupational hazards under linguistic spherical fuzzy environment. The linguistic spherical fuzzy sets are utilized to deal with the vague and uncertain risk assessments of occupational hazards provided by experts. An integrated TODIM‐PROMETHEE algorithm is introduced to determine the risk priority of the identified occupational hazards. Moreover, we extend the indifference threshold‐based attribute ratio analysis method to derive the relative weights of risk criteria based on linguistic spherical fuzzy information. Finally, the OHS risk analysis of medical staff in a hospital is presented to illustrate the effectiveness and availability of our proposed model. Results show that the TODIM‐PROMETHEE framework being developed in this study provides a useful, effective, and practical way for the risk assessment of occupational hazards in OHS.
