“…So, from the high-level modeling presented in this paper, we will add appropriate details to make a lower-level modeling using more robust formal methods suitable to the verification and validation of safety-critical systems. This will be conducted either by adapting the transformation approaches already existing in the literature [43][44][45][46][47], or by proposing a new transformation approach. Future research should focus on analyzing distributed SA, in which UAVs work together towards a common goal as a swarm.…”

The use of unmanned aerial aircrafts (UAVs) is governed by strict regulatory frameworks that prioritize safety. To guarantee safety, it is necessary to acquire and maintain situational awareness (SA) throughout the operation. Existing Canadian regulations require pilots to operate their aircrafts in the visual line-of-sight. Therefore, the task of acquiring and maintaining SA primary falls to the pilots. However, the development of aerial transport is entering a new era with the adoption of a highly dynamic and complex system known as advanced air mobility (AAM), which involves UAVs operating autonomously beyond the visual line-of-sight. SA must therefore be acquired and maintained primarily by each UAV through specific technologies and procedures. In this paper, we review these technologies and procedures in order to decompose the SA of the UAV in the AAM. We then use the system modeling language to provide a high-level structural and behavioral representation of the AAM as a system having UAV as its main entity. In a case study, we analyze one of the flagship UAVs of our industrial partner. Results show that this UAV does not have all of the technologies and methodologies necessary to achieve all of the identified SA goals for the safety of the AAM. This work is a theoretical framework intended to contribute to the realization of the AAM, and we also expect to impact the future design and utilization of UAVs.

“…Jarraya and Debbabi demonstrated a method of probabilistic verification of SysML activity diagrams by transforming them into the PRISM (probabilistic symbolic model checker) on a banking operation consisting of 10 actions (Jarraya and Debbabi 2012). Rahim, Hammad, and Boukala-Ioualalen described an approach to verification by transforming activity diagrams into the Petri net markup language (PNML) and demonstrated it on a vending machine activity diagram consisting of 9 actions (Rahim, et al 2015). Our work does not use model transformations because they have not been successfully applied to large system models.…”

Model‐based systems engineering depends on correct models. However, thus far, relatively little attention has been paid to ensuring their correctness. This paper describes a methodology for performing verification and validation on models written in SysML. The methodology relies on a catalog of candidate requirements that can be tailored for a specific project. Both manual and automated methods are used to verify and validate these requirements. Manual methods are necessary where knowledge of the domain and other extrinsic characteristics are necessary. Automated methods can be used where the requirements cover the use of SysML. Examples from a public domain SysML model of a satellite are presented to demonstrate application of automated requirements verification.

“…Another approach consists of translating a UML activity diagram into CPN (Colored Petri Nets) specifications [28,4] to attribute a formal semantics for UML activity diagrams and verify their properties. Recent contributions focus on the verification of SysML activity diagrams through their translation into Recursive RECATNets [29] and into Modular Petri Nets [30]. Yet here, neither OCL, action constraints nor activity partitions are considered.…”
