Autonomous systems, including airborne, land-based, marine, and underwater vehicles, are increasingly present in the world. One important aspect of autonomy is the capability to process information and to make independent decisions for achieving a mission goal. Information on the level of risk related to the operation may improve the decision-making process of autonomous systems. This article describes the integration of risk analysis methods with the control system of autonomous and highly automated systems that are evaluated during operation. Four main areas of implementation are identified; (i) risk models used to directly make decisions, (ii) use of the output of risk models as input to decision-making and optimization algorithms, (iii) the output of risk models may be used as a constraint in or modifying constraints of algorithms, and (iv) the output of risk models may be used to inform representations or maps of the environment to be used in path planning. A case study on a dynamic positioning controller of an offshore supply vessel exemplifies the concepts described in this article. In addition, it demonstrates how risk model output may be used within a hybrid controller.

As owners contemplate major capital upgrades and investments into their existing chiller plants, several considerations become apparent and require a thorough appraisal. These primary considerations include: Age of existing equipment, existing load profile, utility rates, building occupancy and tenant use, property repositioning plan, lease type and the property's asset strategy, and others. In Aventine's case, the building was considered by most real estate professionals and owners as a relatively young building at 17 years old. The building and chiller plant still had a good five to seven years of serviceable life. The challenge in this particular case was to propose an upgrade justifying replacement of this still functioning chiller plant while asking for approximately $500k in capital expense funds. In addition to describing the technical features of this next-generation chiller plant system, this case study will attempt to integrate financial decision making attributes that assisted in the decision making process. The focus of this paper is to differentiate this technology and approach with major chiller plant upgrades.

This chapter examines the effect of group dynamics on the 2016 decision within the administration of President Barack Obama to lead the international coalition in a mission to liberate Raqqa, Syria, from the Islamic State. The authors show that whereas the groupthink syndrome characterized the decision-making process of the US-led coalition’s decision to attack Raqqa, it was polythink that characterized the decision-making dynamics both in the US-led coalition and within the inner circle of Obama’s own foreign policy advisors. Through case-study analysis, the authors illustrate that groupthink is more likely in strategic decisions, whereas polythink is more likely in tactical decisions.

The present study investigates the level of empowerment among tribal women in terms of their participation in the decision-making process and to identify the factors that affect their level of participation. Fifty women from the Gujjar community of Kashmir Valley were selected through a purposive sampling technique. The interview and case study methods were employed for collecting data from the potential participants. The study revealed that tribal women’s right to make decisions was confined to minor household issues only. A significant positive correlation was also noted between family size, type of family, age, level of education, employment status and participation of the tribal women in decision-making.

Purpose The purpose of this paper is to investigate and explain how organizations in the construction sector can enhance their decision-making process (DMP) by practising knowledge management (KM) and business process management (BPM) activities. A conceptual framework is developed that recognises the elements that impact DMP in terms of KM and BPM. The development of this framework goes beyond current empirical work on KM in addition to BPM as it investigates a wider variety of variables that impact DMP. Design/methodology/approach A case study is undertaken in the context of the construction industry in Jordan. A theoretical framework is developed and assessment of the proposed framework was undertaken through a questionnaire survey of decision-makers in the construction sector and expert interviews. Findings The outcomes of this research provide several contributions to aid decision-makers in construction organizations. Growth in the usage of KM and BPM, in addition to the integration between them, can provide employees with task-related knowledge in the organization’s operative business processes, improve process performance, promote core competence and maximise and optimise business performance. Originality/value Through the production of a framework, this study provides a tool to enable improved decision-making. The framework generates a strong operational as well as theoretical approach to the organizational utilization of knowledge and business processes.

The paper investigates how different hierarchy structuring in analytic hierarchy process (AHP) may affect the final results in the decision-making process. This problem is analyzed in a case study of the Rila monastery forest stands in Bulgaria. There were three similar and mutually overlapped hierarchies defined. A decision maker evaluated all of them and after analyzing final results and consistency performance, he selected and revised the most appropriate hierarchy structure. Consistency check assisted in detecting the judgments which have strongly violated evaluation procedure. These mistakes are interpreted as a consequence of a large number of required pair-wise comparisons. The paper emphases the importance of properly defining hierarchy structure and recommends using consistency analysis as a guide and not as a directive for the revision of judgments.

This research attempts to adopt the individual motivation behind the decision in purchasing an idol merchandise. In addition the resources focused on the concept of consumer motivation and the consumer decision making process. The concept of motivation includes sources of motivation, divided into motivational intrinsic and motivation extrinsic. While the consumer decision-making process is divided into five steps which are recognized the need, looking for information, evaluation of decision, buying decision, and the consumer behavior after purchasing. The researcher uses a case study of the shirt Uniqlo X BT21 with qualitative method. The results of the research which is the consumer motivation lead to purchasing a Uniqlo X BT21 shirt. Parasocial interaction in fact can influence consumers to purchase merchandise. The more closely the relation between society can lead to higher motivation to purchase the needs. The collaboration between Uniqlo and BTS succeeds in attracting the fans. The results of collaboration between brand and public figures now is a strategy for creating promotional products. Entrepreneurs, who also use this strategy need to see the opportunity by using this phenomenon. Penelitian ini mengangkat tentang motivasi individu dalam keputusan pembelian merchandise idola. Konsep yang digunakan yaitu motivasi dan keputusan pembelian. Konsep motivasi meliputi sumber motivasi, yaitu melalui motivasi intrinsik dan motivasi ekstrinsik. Sedangkan untuk keputusan pembelian melalui lima tahapan yaitu, mengenali kebutuhan, pencarian informasi, evaluasi alternatif, keputusan pembelian dan perilaku pasca pembelian. Penelitian ini menggunakan studi kasus terhadap kaos Uniqlo X BT21 dengan metodologi kualitatif. Hasil penelitian ini yaitu motivasi yang menyebabkan pembelian kaos Uniqlo X BT21. Interaksi parasosial terbukti mampu untuk mempengaruhi pembelian merchandise. Semakin lekat sebuah hubungan parasosial, maka akan semakin tinggi motivasi minat beli. Kolaborasi yang diadakan Uniqlo dengan BTS dapat dikatakan berhasil menarik minat penggemar. Sehingga kolaborasi merek dan public figure kini merupakan sebuah strategi yang dapat dilakukan untuk mempromosikan produk. Pebisnis perlu melihat peluang yang hadir dalam fenomena tersebut.
