Enhancement of FMEA risk assessment with SysML

Abstract: Assuring the safety of workers and passengers is a primary concern that has to be addressed in transport systems such as Heavy Rail. Introduction of new technologies into existing operation...

An Architecture Framework Modification Supporting the Acquisition Stakeholders

Abstract: Architectural modeling is gaining support for urban system development to help governments, local agencies and large enterprises acquire, maintain and develop complex infrastructure. This paper proposes a modification to TRAK (The Rail Architecture frameworK) to make it more suitable for acquisition of the general class of urban infrastructure systems. In this paper four of the main system stakeholders, namely acquirer, developer, investor and regulator are chosen and their concerns are identified. In order to identify the gaps, the procurement viewpoints of TRAK are investigated and analyzed to show their inefficiencies in expressing acquisition scenarios and addressing the concerns of those stakeholders. The first main gap is the lack of requirement traceability as there is no viewpoints showing the flow of requirements from acquirer to developers. Also, there is no customized requirement for investor and regulator who have concerns beyond the direct infrastructure system level. As a response to those gaps, four viewpoints are created by using a mixture of TRAK elements. Some new elements are added to TRAK as the existing elements are not enough for creating three of the viewpoints. Finally, the viewpoints are implemented to create a view showing the parts of the architecture which are of concern to those stakeholders. A SysML requirement diagram is used to implement the first two viewpoints as it supports the requirement traceability.

Towards the integration of organisational culture models into model-based systems engineering approaches for enterprise systems transformation

Abstract: Enterprise systems modelling requires integrated views of both technical systems as well as organisational systems that together will deliver the anticipated capabilities. A major challenge in such...

Employing the model based systems engineering methodologies to develop a domain specific language for contracting of infrastructure projects

Abstract: The procurement of infrastructure systems by the public sector is very costly, long and not transparent since the processes are based on preparing huge amounts of documents which are difficult to be kept consistent and to be used (e.g. bid evaluation). Acquisition architecture frameworks (AF) are metamodels, developed to model the whole enterprise/system life cycle stages including system procurement. Our previous study analyzed the currently used AFs such as DoDAF, MoDAF and TRAK to assess their adequacy and efficiency in modelling the infrastructure projects. The results showed that many of the procurement related concerns are overlooked such as financial matters e.g. cost and revenue calculation; and risk management aspects e.g. risk calculation and risk allocation. This paper focuses on identifying the procurement concerns and adding new viewpoints to the architecture frameworks; and developing a domain specific language based on SysML to model the new viewpoints. A methodology is provided which shows how the metamodel (abstract syntax) and the language stereotypes (concrete syntax) are developed. The results firstly show the 18 identified viewpoints of procurement domain and then one of them (project funding) is chosen to be described in this paper. The conceptual definition of the ‘project funding’ viewpoint and the models it generates are illustrated as example diagrams of this DSL. This DSL can be used by the domain practitioners, who are the contracting officers and procurement managers, to generate the contracting materials to facilitate the contracting process, assure the consistency of the procurement documents, giving better project outcomes.
