The approach to construction of model of a problem situation in transport system is resulted, the block diagram of its algorithm is developed. It is revealed that the transition stage from the problem to the formulation of formal tasks is a problem situation, and the tasks can be solved in different ways, forming a set of strategies. It is noted that in the general case the result of operations is uncertain, which is caused by the uncertainty of the conditions of the operation and the action of factors of different nature. It is revealed that the acquisition of values of indicators that characterize one or another result of the operation is associated with the solution of the problem of modeling operations. The stages of the problem of studying the efficiency of the operation in the transport system are given. A number of assumptions are made about the process of obtaining results, which is associated with the formation of the operation model and obtaining efficiency estimates based on modeling results, as well as the process of analyzing the results, which involves solving the selection problem based on the established efficiency criterion or system of such criteria. It is found that the model of the problem situation in transport systems reflects the relationship of the main elements of the decision-making process and the sequence of formation of partial tasks and is built to cover the problem of decision-making as a whole, to present its main elements to be finalized. about the strategy of the operation. It is shown that the presence of a certain component as an independent element in the model of the problem situation assumes that the set of values of uncertain factors in the development of solutions will be either set externally, or finding these values will be an independent task. A list of actions for solving partial problems based on this model is presented. It is shown that in many practical cases it is observed that the a priori task of one of the main criteria of efficiency leads to the selection of some set of alternatives. Therefore, the choice of the best alternative requires the formation of a compound criterion, which includes both formal and informal prescriptions for making a judgment on the basis of which the selection or return and correction of elements of the model of the problem situation.

This chapter investigates the main concepts and activities of information in strategic decision-making systems. Since information became the global economy value source for organizations, information assumes a key role in contributing to the development of the performance of organizations through the selection of relevant information for businesses. The relationship of the strategic management of information with business activities contributes to the process of strategic decision making for more effective and efficient decisions. The understanding of the importance of information as a strategic resource in the management of organizations is becoming more important to strategists than the formulation of strategy models of industrial society. In the twenty-first century, no manager will be able to set and implement the strategy successfully without a basic understanding of information for strategic decision making.

To evaluate objects under uncertainty, many fuzzy frameworks have been designed and investigated so far. Among them, the frame of picture fuzzy set (PFS) is of considerable significance which can describe the four possible aspects of expert’s opinion using a degree of membership (DM), degree of nonmembership (DNM), degree of abstinence (DA), and degree of refusal (DR) in a certain range. Aggregation of information is always challenging especially when the input arguments are interrelated. To deal with such cases, the goal of this study is to develop the notion of the Maclaurin symmetric mean (MSM) operator as it aggregates information under uncertain environments and considers the relationship of the input arguments, which make it unique. In this paper, we studied the theory of MSM operators in the layout of PFSs and discussed their applications in the selection of the most suitable enterprise resource management (ERP) scheme for engineering purposes. We developed picture fuzzy MSM (PFMSM) operators and investigated their validity. We developed the multiattribute decision-making (MADM) algorithm based on the PFMSM operators to examine the performance of the ERP systems using picture fuzzy information. A numerical example to evaluate the performance of ERP systems is studied, and the effects of the associated parameters are discussed. The proposed aggregated results using PFMSM operators are found to be reliable as it takes into account the interrelationship of the input information, unlike traditional aggregation operators. A comparative study of the proposed PFMSM operators is also studied.

Informed consent is key to ethical clinical research and treatment, but partially rests on the ability of individual patients or research participants to use disclosed information to make a meaningful choice. Although the construct of decisional capacity emerged from legal and philosophical traditions, several investigators have begun examining the relationship of specific neuropsychological abilities to decisional capacity. This line of research may foster development of better consent procedures, as well as aid in refining the construct of decisional capacity toward a form that better reflects the underlying neurocognitive processes. We conducted a systematic search of the published literature and thereby identified and reviewed 16 published reports of empirical studies that examined the relationship between specific neuropsychological abilities and capacity to consent to research or treatment. Significant relationships between neuropsychological scores and decisional capacity were present across all the reviewed studies. The degree to which specific neuropsychological abilities have particular relevance to decisional capacity remains uncertain, but the existing studies provide a solid basis for a priori hypotheses for future investigations. These ongoing efforts represent an important conceptual and empirical bridge between bioethical, legal, and neuropsychological approaches to understanding meaningful decision-making processes.

BACKGROUND: Cancer is a disease caused by abnormal growth of body cells that turn malignant and continue to grow uncontrollably. One of the treatments for breast cancer is mastectomy. The quickness of decision-making determines the survival rate of prognosis patients. OBJECTIVE: This study aimed to determine the relationship of self-acceptance with decision-making duration in cancer patients to perform a mastectomy. METHODS: An analytic observation method with cross-sectional design. The samples were taken by purposive sampling method with 50 samples of breast cancer patients. Data collected include age, last level of education, marital status, profession, stage of cancer during mastectomy, self-acceptance score, and decision-making duration to perform a mastectomy. RESULTS: The data analyzed with the Kruskal–Wallis test. The test showed the relationship of self-acceptance (p = 0.027) with decision-making duration in breast cancer patients to perform a mastectomy. CONCLUSION: In Conclusion, there is a relationship of self-acceptance with decision-making duration in breast cancer patients to perform a mastectomy.

A lessening of personal discomfort felt by residents on-call in the Emergency Psychiatric Service has resulted from changes in the frequency of being on-call, exclusion of beginning residents from duty and arranging for the presence of a faculty psychiatrist for one or two hours during each on-call period. Coincidental significant reductions in the number of cases admitted to hospital and reductions in the proportion of discrepancies between diagnoses made by the emergency resident and those made later by inpatient unit staff have been described. The relationship of the changes in resident experience to the reduction in admissions and decreased proportion of diagnostic discrepancy has been discussed using a model of the process of emergency psychiatric admission described earlier by Bartolucci et al. (1). Less isolation, anxiety and some increased experience on the part of the psychiatric residents on duty in the Emergency Psychiatric Service results in greater awareness and better appraisal of the nonmedical aspects of psychiatric emergencies.
