Situational Management

The problems of organizing medical care in the context of the COVID-19 pandemic, associated with the uncertainty and limitedness of various resources, led to the need to improve decision-making systems for hospitalization of patients. Situational management can improve the decision-making process to fit the current situation better. At the same time, it becomes important to take into account the influence of psychological factors on decisions made during hospitalization. The paper proposes the use of coalition games for situational management during hospitalization of patients. The players and members of the coalition are hospitals, ambulance teams, patients and computed tomography centers. The goal of the game is to form a coalition of participants that provides the maximum benefit in terms of time and cost of hospitalization at the time of decision making. The general scheme of hospitalization, the main sources of information about the situation, the formulation and formalization of the problem are considered. An experiment was carried out in which the formation of a coalition during hospitalization was tested based on data obtained from analyzing the dynamics of the COVID-19 pandemic. Due to the small amount of data and the lack of approved models of the situation development, when carrying out the calculation, some of the parameters were estimated using heuristic models of the development of the situation, based on the analysis of information from open sources of information. The experiment result contains a set of coalitions that provide the maximum benefit under the specified constraints. At the same time, the calculation time of the coalition game allows using the proposed model of decision-making support during hospitalization in the dispatch service of ambulance stations.

Living in permanent social groups forces animals to make decisions about when, how and with whom to interact, requiring decisions to be made that integrate multiple sources of information. Changing social environments can influence this decision-making process by constraining choice or altering the likelihood of a positive outcome. Here, we conceptualized grooming as a choice situation where an individual chooses one of a number of potential partners. Studying two wild populations of sympatric primate species, sooty mangabeys ( Cercocebus atys atys ) and western chimpanzees ( Pan troglodytes verus ), we tested what properties of potential partners influenced grooming decisions, including their relative value based on available alternatives and the social relationships of potential partners with bystanders who could observe the outcome of the decision. Across 1529 decision events, multiple partner attributes (e.g. dominance ranks, social relationship quality, reproductive state, partner sex) influenced choice. Individuals preferred to initiate grooming with partners of similar global rank, but this effect was driven by a bias towards partners with a high rank compared to other locally available options. Individuals also avoided grooming partners who had strong social relationships with at least one bystander. Results indicated flexible decision-making in grooming interactions in both species, based on a partner's value given the local social environment. Viewing partner choice as a value-based decision-making process allows researchers to compare how different species solve similar social problems.

This study examines the characteristics of students with disabilities who participate in Open Enrollment (one of seven enrollment options available in Minnesota), the reasons they participate, and the sources of information and decision-making process involved with choosing another district. Surveys of 347 parents revealed three primary reasons for transferring their children: The child's special education needs being better met at the new district, more personal attention from the teacher, and dissatisfaction with the resident school. Other factors, such as disability category, parents' income, and location, were also analyzed.

The Subject

Drivers of merging vehicles decide when to merge by considering surrounding vehicles in adjacent lanes in their deliberation process. Conflicts between drivers of the subject vehicles (i.e., merging vehicles) in an auxiliary lane and lag vehicles in the adjacent lane are typical near freeway on-ramps. This paper models a decision-making process for merging maneuvers that uses a game theoretical approach. The proposed model is based on the noncooperative decision making of two players, that is, drivers of the subject and lag vehicles, without consideration of advanced communication technologies. In the decision-making process, the drivers of the subject vehicles elect to accept gaps, and drivers of lag vehicles either yield or block the action of the subject vehicle. Corresponding payoff functions for two players were formulated to describe their respective maneuvers. To estimate model parameters, a bi-level optimization approach was used. The next generation simulation data set was used for model calibration and validation. The data set defined the moment the game started and was modeled as a continuous sequence of games until a decision is made. The defined merging decision-making model was then validated with an independent data set. The validation results reveal that the proposed model provides considerable prediction accuracy with correct predictions 84% of the time.

A complex or unstructured problem is based on multi criteria not on a single criterion. A contractor selection problem is a multi-criteria problem. A correct decision-making is required for selecting the appropriate contractor for a construction project. Selection of a contractor is a key decision made by clients and the process of selection a contractor has become an important issue in construction projects. Many multi-criteria techniques have been proposed and applied to such problems solution. This paper aims to propose integrated model for MCDM. The integrated model contains two stages. First stage integrates two MCDM methods are AHP and ANN to prepare a shortlist of the best alternatives. Second stage apply statistical model COP to choose the optimum alternative from the best alternatives in a shortlist. Proposed model for tendering system provides automated a decision-making process that reduces the time and manpower requirements for processing tender

This article builds on the idea that senior tourists’ decision making is a staged process in which the different choices are sequential, interrelated, and interdependent. These decisions are “whether to take a vacation," “whether to opt for an international trip," “whether to use an organized tour," and “whether to use publicly subsidized travel.” Considering the social character of many trips offered to seniors, the fourth decision of the proposed process makes it unique. No research has empirically considered using a staged decision making in the context of senior travelers, and the proposed model quantifies the effect of each variable based on the decision the individual is dealing with; also, the way a variable changes its effect even within the same decision stage depending on the individual is analyzed by including heterogeneity into the modeling. The results find that senior tourists follow the proposed four-staged decision-making process rather than the basic two-stage decision-making process.

Collaborative Decision

This case study describes a collaborative decision-making process for developing effective academic accommodations for a music major with a disability, whose prior accommodations suggested by the Disability Support Services (DSS) failed to address her needs. Cross-departmental collaboration between the DSS and the School of Music, as well as dynamic interactions among students with disabilities (SWDs), faculty members, peer tutors, and DSS specialists are emphasized. Multiple sources of information were collected, including in-depth/semi-structured interviews and a review of all relevant documentation such as case reports, weekly logs, email correspondence, results of psychological testing and academic portfolio contents. The themes that emerged from the data include resistance to the unknown, the language of negotiation, the decision-making process, and transformation (with three sub-themes: from fear of stigmatization to self-advocacy, from resentfulness to acceptance and commitment, and from reaction to pro-action). Key elements contributing to the collaborative process consist of effective communication among all members, the promotion of self-advocacy skills for SWDs, and faculty’s recognition of SWDs’ potential to succeed and while engaging flexible methods for delivering course content and assessing outcomes. A framework for delivering viable services for music majors with disabilities is outlined and discussed.
