Integration of risk analysis methods in aerospace research projects
Independent Journal of Management & Production, 2022
Organizations are exposed to several types of risks, such as environmental, legal, operational, financial, and technological; that are subjected to epistemic uncertainty. In this context, a contemporary issue is how to deal with accidents, with greater difficulty in understanding the sociotechnical system, due to its complex and dynamic characteristics, in an attempt to prevent accidents based on components’ behavior. Although, for most complex systems and projects, a record of the exposure to hazards is incomplete or nonexistent, especially when it is highly innovative. This study developed a risk analysis framework for complex aerospace research projects by integrating different methods: problem structuring, safety control action analysis, and prioritization of results. Three methods are proposed: (1) Soft Systems Methodology (SSM) for initial review and understanding of the problem situation, and preliminary identification of hazards and losses; (2) Systems-Theoretic Process Anal...
Assessing the wide diversity of risk types in large and complex projects using the traditional hyperbolic iso-risks curves may seem a simplistic and reductive approach, and evaluating the risk factor through the multiplication of likelihood and severity parameters results in defining as dangerous those risks that are associated either with rare but devastating consequences or with probable but minor effects. In this work, the authors aimed at focusing on those risks that, despite their low occurrence probability, may significantly compromise a project result. To this extent, a different formula has been used to compute the risk factor, keeping into account risk detectability and evaluating the potential consequences in four different domains (cost, time, performance, reputation). This approach has been validated on the case of a large industrial project related to the launch of an innovative mobile telecommunications system, collecting the experts' opinions in a primary Italian firm in aerospace industry.
Risk management in the aeronautical industry: results of an application of two methods
Risk Analysis VI, 2008
This article presents the results of two risk management methods, applied in the aeronautical industry, during the development of an aircraft for the executive market. The first method is the risk management in accordance with the best practices of Project Management International (PMI), and the second is a proposal of risk management based on Multicriteria Fuzzy Analysis (MFA). The PMI method of risk management is already widely used by the market. Its terminology is quite similar to other international standards of risk management. The MFA risk management method is a new proposal that requires specialist opinions, through a questionnaire, to identify internal and external project risks, measuring their level of threat to the project success. The structure of the questionnaire follows Risk Breakdown Structure (RBS) methodology of the PMI. This new approach generates indicators at three levels: operational, tactical and strategic, which facilitates the monitoring and the management of risks. Despite its complex mathematical base, the MFA method is easier to implement. Both methods reach a similar degree of risk indicators for the project; however, the MFA can be used in an earlier phase of the project, which can avoid some possible earlier risk entanglements. Due to the particularities of each method, both show important contributions to the project risk management. Therefore, complex projects should use both methods to achieve adequate risk management.
Qualitative Risk Analysis Methods in Aviation Projects
2011
Project risk management attempts to anticipate and provide a solution regarding the uncertainties that pose a threat to project objectives and terms, to identify all the foreseeable risks, assessing the chance and severity of those risks, and then deciding what might be done to reduce their possible impact on the project or avoid them altogether.

Contemporary project risk management literature introduces uncertainty, i.e., the lack of information, as a fundamental basis of project risks. In this study the authors assert that equivocality, i.e., the existence of multiple and con-flicting interpretations, can also serve as a basis of risks. With an in-depth empirical investigation of a large complex engineering project the authors identified risk sources having their bases in the situations where uncertainty or equivocality was the predominant attribute. The information processing theory proposes different managerial practices for risk management based on the sources of risks in uncertainty or equivocality.
Risk Evaluation of Production and Implementation of the Project
DAAAM Proceedings, 2016
One of the key parts during the project cycle of the technical projects is also a risk evaluation of production and implementation of the project itself in all phases of the production. In this paper, we will examine the correlation of one of the risks (i.a. political risk) that are taken in consideration during risk analysis production and which are in direct correlation with the current status of country's development status in which the projects are conducted, specifically in this case of countries which are new members of EU. Critical risk in that case is the policy and institutional aspects, including existing economic policies and development plans, organisation and management of services to be provided/developed by the project, as well as capacity and quality of the institutions involved.
Risk Assessment of Accidents in the Conception Phase of Engineering Projects
This paper presents the result of a survey conducted with specialists to show the importance of mitigating project engineering inadequacies that can lead to severe labor accidents and also shows an example of application of risk assessment in the construction of a bicycle lane project. This topic is quite important because some serious accidents have occurred in the execution phase of a project engineering, caused by project inadequacies. Lives have been lost due to project engineering inefficiencies, and this paper intends to alert of the criticality of this issue, which is only addressed when a major accident occurs. The objective of this paper is to show the difficulties faced by many project managers and engineers generally when they have to adapt the project engineering to the existing safety work norms in the final execution phase, once the initial phase of the project engineering was not well performed, by giving practical examples that have occurred in the industry. As a methodological approach, a project management checklist (PMC), is proposed as a key element of this methodology to be customized to each engineering project together with the probability and impact matrix to categorize the level of each risk as high, extremely high or medium. The study also includes a broad research of the literature on the theme as well as two field studies, one with project management and labor safety engineering professionals and another with various companies to know what they thought about this topic and the measures they are taking to eliminate serious accidents in their businesses. The study demonstrates that risk assessment can identify serious accident risks in the conception phase of projects and basic engineering. This paper provides responses to an important research question. As a result, the method revealed that 60% of the companies researched are only concerned with potential serious accident risks in the execution phase of the projects, probably due to the high costs of experienced manpower in the initial phase when the risks are somehow hidden since the project hasn't started yet. The study recommends Prevention through Design (PtD), i.e. It is of extreme importance to identify risks in the conception phase of projects and basic engineering, prevent occupational injuries and control them during work operations. As a final recommendation, risk assessment should be considered mandatory by the Project Engineering Management Organization and the Engineering and Architecture Councils and part of all the construction inspections made by the public and private engineering companies in Brazil and in other countries.
Evaluating Sources of Risks in Large Engineering Projects: The Roles of Equivocality and Uncertainty
International Journal of Management, Knowledge and Learning, 2015
Contemporary project risk management literature introduces uncertainty, i.e., the lack of information, as a fundamental basis of project risks. In this study the authors assert that equivocality, i.e., the existence of multiple and conflicting interpretations, can also serve as a basis of risks. With an in-depth empirical investigation of a large complex engineering project the authors identified risk sources having their bases in the situations where uncertainty or equivocality was the predominant attribute. The information processing theory proposes different managerial practices for risk management based on the sources of risks in uncertainty or equivocality.
