“…A matrix of alternatives, or morphological matrix, is formed by "identifying the major functions or characteristics of a system on the vertical scale, and all the possible alternatives (or system attributes) for satisfying the characteristics on the horizontal scale" [39]. The IRMA extended the capability of the matrix of alternatives by incorporating new concepts such as filters, compatibility matrices, or multi-attribute decision-making techniques into the selection of product features [42]. For the purpose of this work, Interactive Reconfigurable Matrices of Alternatives were developed and applied to each layer of the proposed decomposition to help understand interrelationships between improvements, concepts, functions and technologies.…”

The successful development and implementation of both European and American aviation modernization programs require active cooperation, harmonization, and interoperability among air transportation systems. Although significant efforts have been made toward collaboration and synchronization, additional work is required to harmonize capabilities, terminology, assumptions, standards, and implementation schedules. This paper presents a rigorous approach and visual environment to instantaneously examine and compare the components of both European and American programs and to further identify and understand the nature of their relationships. In particular, it provides a unique and interactive means to investigate and compare both programs, roadmaps, terminologies, and definitions.

“…These differences were demonstrated next to a Interactive Reconfigurable Matrix of Alternatives (IRMA). [7] It was very clear that today's UAS are not suited for a SEAD mission but their communication structures contain useful information on how to design the new UAS. Based on the interoperability scale mentioned above, today's systems rank at IOL 0.…”

This research details the development of a design process and decision-making environment to support the acquisition of an air-based, interoperable, autonomous system-of-systems to support suppression of enemy air defenses missions. 12 The design is done using a three part process, which includes the concurrent development of the DoDAF products, modeling and simulation environment, and decision support environment. In particular, the research focuses on understanding how the interactions, interoperability, and autonomy level of the unmanned aircraft affect the overall mission performance.

“…Simultaneously, to further define the problem, a literature search is conducted to determine the engineering characteristics that are likely to be used to describe a product of the intended type and to survey the state-of-the-art to identify potential concepts that will meet the customer need. When existing concepts are lacking, the concept of the Interactive Reconfigurable Matrix of Alternatives (IRMA) proposed by Engler et al may be implemented to synthesize new concepts from their basic constituent elements [31]. In practice, the conceptual synthesis and literature search phases must go hand-in-hand to identify the full range of potential engineering characteristics that may be related to the customer requirements.…”

Design is a decision-making process that depends on multiple attributes. Analysis of alternatives with respect to a single metric representing the "goodness" of the concept is difficult without resorting to subjective weightings on an overall evaluation criterion. The use of subjective factors in a decision-making process is often met with criticism, as the selection of a design may be traced to preferential decisions made on a certain day by a single individual. A methodology is needed that reduces the impact of uncertainty in the subjective weighting factors while retaining the traceability, defensibility, and rigor provided by traditional multiple attribute decision-making techniques. In this work, a standard process for systems engineering using the quality function deployment approach with a multiple attribute decision-making technique for concept selection is supplemented through the use of parametric slide bars to play "what-if" games and a probabilistic environment that plays all possible "what-if" games and summarizes the results. Using the modified process, families of concepts can be rapidly examined based on varying levels of subjective preferences. Decision makers, armed with a rapid parametric sensitivity analysis tool, can make more informed decisions about future concepts, policies, and acquisition decisions. An interactive graphical environment can be used to visualize the diverse sets of trades and understand non-intuitive answers by tracing customer needs to proposed solutions in real-time. In practice, the proposed process facilitates iteration between needs and concepts and fosters and increased understanding of the concept space between designer and decision maker.
