“…MAUT has been incorporated in the multi-attribute trade-space exploration (MATE) paradigm for generating a multitude of system designs and identifying the optimal ones, [118], [119], [120] and [121]. It was also applied in establishing the requirements' specification of commercial aircraft [122], in evaluating space system designs for the telecommunications and deep-space observation missions [103], and the development of satellite value models [123].…”

The work presented in this thesis concerns the development of a value driven engineering design assessment framework and its application to the conceptual design of an Unmanned Air System (UAS) to be utilised in a defence application. This research demonstrates the implementation of the value driven design philosophy in this framework, identifying value enhancing designs, with value not converted to monetary worth and as perceived by all stakeholders involved. A multi-criteria and multi-stakeholder decision making analysis is adopted to address their preferences as well as to study their interacting strategic choices. The ultimate objective of this framework is to convert engineering design to a decision making analysis with multiple conflicting objectives of multiple stakeholders considered.This framework is capable of providing a product definition and estimation of all performance and cost related attributes for the conceptual phase. However, instead of pertaining to a single aircraft concept, a broad range of combinations of UAS configurations and geometries is generated by systematically searching alternative concepts and design configurations through a novel parameterization of the aircraft geometric topologies.Value, related to the designed system's capabilities or performance and lifecycle cost, is used to compare different alternatives in the decision making of engineering design through the appropriate value model. Following a valuefocused approach, a novel multi-attribute value model is introduced for objectively capturing the stakeholder's preferences and expectations. Furthermore, a more sophisticated multi-attribute utility model, based on standard Multi-attribute Utility Theory, is employed in the evaluation.Game Theory as an optimization tool is used to develop a novel hybrid cooperative/non-cooperative non-zero sum, complete information game among all involved stakeholders as players. This game successfully addresses the stakeholders' preferences in a functional outcome-focused way, resolving the high indeterminacy of the alternative designs through a cooperative game. At the same time, their strategic interactions are captured in a process-focused non-cooperative game. Hence, the optimal design is identified through the simultaneous employment of the Nash bargaining solution and the Nash equilibrium.i

“…P2. Customer needs are almost always given weights independent from range information of attributes that is utilized for measuring the attainment of customer needs (Zhang et al 2011). This may be caused by the ambiguity of customer needs themselves or the difficulty in identifying the measurements or metrics to be used for customer needs.…”

Recently, customer--based product development is becoming a popular paradigm.Customer expectations and needs can be identified and transformed into requirements for product design with the help of various methods and tools. However, in many cases, these models fail to focus on the perceived value that is crucial when customers make the decision of purchasing a product. In this paper, a prescriptive approach to support value--based requirements engineering is proposed, describing the foundations, procedures and initial applications in the context of requirements engineering for commercial aircraft. An integrated set of techniques, such as means--ends analysis, part--whole analysis and multi--attribute utility theory is introduced in order to understand customer values in depth and width. Technically, this enables identifying the implicit value, structuring logically collected statements of customer expectations, and performing value modelling and simulation.Additionally, it helps to put in place a system to measure customer satisfaction that is derived from the proposed approach. The approach offers significant potential to develop effective value creation strategies for the development of new products.

“…Past work has focused on creating linearized component value models from system value model that is formed using a multiattribute utility function, where the emphasis of the component value models is on the corresponding component's attribute, and lacks the representation of disciplinary/subsystem couplings. 19,20 Traditional requirements-based systems engineering approaches do not directly capture or use physics-based couplings in the design process at the system level. The field of multidisciplinary design optimization (MDO) was developed specifically to capture and model the couplings between disciplines [21][22][23][24] to enable a system analysis and optimization that ensures consistency in the physics.…”

Large‐scale complex engineered systems are designed in large organizations consisting of hundreds or thousands of individuals making design decisions at different stages in the process. These complex systems are inherently multidisciplinary and uncertain, involving diverse disciplines spanning geographical locations. Without a means to guide their decisions, these many decision‐makers fall back on selecting a design according to their own value and risk preferences. The primary focus of this paper is to enable consistency in design decision‐making with respect to both value and risk preferences of the stakeholder. A new value‐based systems engineering (VBSE) framework is presented that enables physics‐based system consistency as well as consistency in communication of value and risk preferences for design decision‐making in a hierarchically decomposed system. This framework embraces principles of value‐driven design and multidisciplinary design optimization, while also ensuring consistency in risk preferences throughout the system to address uncertainty. Improper communication of risk preferences could result in nonoptimal designs, which are risk biased by the design decision‐makers at different levels of the hierarchy, with respect to the stakeholder's preferences. Consistency in risk preferences in the context of the VBSE framework is addressed in this research by incorporating decision analysis techniques.
