Regarding all methods of decision making as parts of the same subject, one is astounded to find that the field speaks to the practitioners about multicriteria decision making with a multi-forked tongue, different methods give different and conflicting outcomes even for very simple decisions. In this paper, five well-known decision theories are described and used to work out a simple decision to choose the best of three cars. The outcomes turn out not to be the same for all the methods, which is troubling because one would expect unique answers in decision making. Several "meta" criteria that are essential for making a decision theory to make a choice as to which decision approach is best.h is best.

This paper presents a fuzzy-goal programming(FGP) approach for Bi-Level Linear Multiple Objective Decision Making(BLL-MODM) problem in a large hierarchical decision making and planning organization. The proposed approach combines the attractive features of both fuzzy set theory and goal programming(GP) for MODM problem. The GP problem has been developed by fixing the weights and aspiration levels for generating pareto-optimal(satisfactory) solution at each level for BLL-MODM problem. The higher level decision maker(HLDM) provides the preferred values of decision vector under his control and bounds of his objective function to direct the lower level decision maker(LLDM) to search for his solution in the right direction. Illustrative numerical example is provided to demonstrate the proposed approach.

This paper presents an analysis of the impact of the causal looping method to the Korean middle managers' decision-making processes. The sample included the observations of decisions made by 70 groups with 5 to 7 members each. The results showed that the causal looping method was a strong device to help Korean managers followed value-focused decision processes, as opposite to alternative-focuses ones. The lessons from this study suggest a direction for the development of the education method to improve group decision-making processes.

This investigation was a descriptive study that examined the relationship among factors including professional autonomy, role conflict, and clinical decision-making ability of nurses on comprehensive nursing service wards. To accomplish this, a survey of 234 nurses working at D city and G city who were selected based on convenience sampling was conducted. Data were collected using a self-reported questionnaire completed by 234 nurses at four clinical hospitals from October 12, 2017 to November 30, 2017. The collected data were evaluated by t-tests, ANOVA, Pearson's correlation and stepwise multiple regression analysis. The mean clinical decision-making ability score was $3.38{\pm}0.78$, which corresponded to an intermediate level of clinical decision-making ability. Clinical decision making ability was positively correlated with professional autonomy, but role conflict showed a negative correlation. The factors having the greatest impact on clinical decision-making ability were found to be, in order, length of work, education level, professional autonomy and role conflict, which together accounted for 38.7% of the total impact. To improve clinical decision making ability, it is important to improve autonomy and role conflict. Additionally, to improve clinical decision-making ability, it is necessary to improve clinical decision-making ability to determine nurses tasks through professional autonomy and role conflict. Overall, the results of this study can be utilized as baseline data when developing a program to enhance nurses' clinical decision making ability. Moreover, it is suggested that an interventional study analyzing validity and effectiveness of developed education programs be conducted.

A CCTV inspection method has been widely used to assess sewer condition and performance, but Korea lacks a proper decision support system for prioritizing sewer repair and rehabilitation (R&R). The objective of this paper is to introduce the results that we have developed in the Sewer Condition Assessment and Rehabilitation Decision-making (SCARD) Program using MS-EXCEL. The SCARD-Program is based on a standardized defect score for sewer structural and hydraulic assessment. Priorities are ranked based on risk scores, which are calculated by multiplying the sewer severity scores by the environmental impacts. This program is composed of three parts, which are decision-making for sewer condition and performance assessment, decision-making for sewer R&R priority assessment, and decision-making for optimal budget allocation. The SCARD-Program is useful for decision-makers, as it enables them to assess the sewer condition and to prioritize sewer R&R within the limited annual budget. In the future, this program logic will applied to the GIS-based sewer asset management system in local governments.

Objective: This study examined differences in preschoolers' prosocial decision-making, emotion understanding in prosocial dilemmas based on the age and emotional conditions of a counterpart child, and the effects of emotion understanding on preschoolers' prosocial decision-making. Methods: The participants were 114 children (35 3-year-olds, 39 4-year-olds, and 40 5-year-olds). Each child was presented individually with prosocial dilemma tasks and was asked to make decisions and understand emotions (in prosocial and desire-fulfilled situations) based on the emotional conditions of a counterpart child. Results: First, the 4- and 5-year-olds showed more prosocial decision-making in prosocial dilemmas than the 3-year-olds. Prosocial decision-making was significantly lower when the counterpart child was angry, rather than neutral or sadness. Second, in prosocial situations, the 5-year-olds displayed higher positive emotion understanding scores than the 3-year-olds, And in desire-fulfilled situations, the 3-year-olds showed positive emotion understanding, whereas the 4- and 5-year-olds showed negative emotion understanding. Finally, children were more inclined toward prosocial decision-making when they showed higher emotion understanding in prosocial situations, lower emotion understanding in desire-fulfilled situations, and greater age. These were equal to all emotional conditions of the counterpart child. Conclusion: These results suggest that emotion understanding is an important component of social cognition, which effects preschoolers' prosocial decision-making.

The purpose of this study is to find out the effects of directors' leadership style and the type of decision-making on improving child care teachers' job satisfaction which is essential to operate high-quality nursing. The survey method was used for 184 child care teachers who work for child care centers. The collected data were analyzed using one-way analysis of variance and posteriori test to find out the differences in teachers' job satisfaction according to their recognition of directors' leadership and decision-making. The result showed that differences exist in child care teachers' job satisfaction according to the leadership and decision-making of directors as recognized by the teachers. The score of child care teachers' self-development, work, welfare & social stability related to job satisfaction hit the highest when directors' leadership type was efficiency-centered. Similarly, participatory decision-making type, which is the most ideal type, scored the highest in all sub-components of job satisfaction in the case of directors' type of decision-making. This implies that the directors who prefer positive leadership and democratic participatory decision-making type increase teachers' job satisfaction which will positively affect the child care centers' qualitative development.

Manufacturing Production System (MPS) has been widely accepted in construction area for the productivity improvement. However, the MPS does not always provide cost and time saving. It often caused more delays and increased project cost. Therefore the use of the MPS technique, systematic decision-making process is needed by reviewing various project parameters such as cost and time. This study includes extensive literature reviews and case studies on MPS. As a result, a decision-making model is proposed. The decision-making flowchart and decision-making model are developed in three steps: (1) identification and categorization of decision-making factors; (2) calculations of benefits, cost, and duration in accordance with the location and the production capacity of the factory; (3) comparisons of MPS and on-site assembly by varying the locations and sizes of the factory
