SysML allow both structural and behavioral modeling of the system. SysML models can be formally interpreted and executed. Ones executed analysis can be performed at system level. Ones we are good with simulation results we can prototype. Using programmable Lego Mindstors NXT for prototyping is an out of the box way to test and demonstrate […]
We present full thesis focusing on SysML and MBSE adoption on one of the most used documents in the industry – Vehicle Feature Code Matrix (VFCM). Note The Master of Science in Product Development program (University of Detroit Mercy) is developed in cooperation with five major U.S. corporations and focused specifically on the automobile industry […]
Product Line Engineering (PLE) is the engineering of a family of related products using a shared set of (digital) engineering assets. In case of physical systems, before the actual production of a product line begins, a whole set of digital artifacts must be maintained to describe the entire family (variants) of products. In the context […]
The Thirty Meter Telescope (TMT) system is currently being developed by the TMT Observatory Corporation. The main objective for the TMT related analysis is to provide state-dependent power roll-ups for different operational scenarios and demonstrate that requirements are satisfied by the design as well as mass roll-ups and duration analysis of the operational use cases. […]
This paper documents the real-world application of model-based systems engineering (MBSE) methodology and principles to an automotive driveline system. A system model developed in the course of this thesis supports the definition and sizing of the driveline system to best communicate and deliver functional specifications tied to customer requirements. Furthermore, this system model documents, organizes, […]
In many industries, like aerospace, defense, telecommunication and others, it’s becoming common to use UML/SysML to describe system architectures. With the introduction of OMG fUML, many companies began refining their models to the level where they became executable. The next big step is to adopt model-based testing in which standard executable models are reused to […]
One of the major factors for wide SysML and MBSE deployment in large industrial projects is the management of Interface Control Documents (ICDs) [1]. ICDs are at the center of systems engineering processes in most industries, and that is not supported in a straightforward way by SysML. [2] Interface Control Documents, known as ICDs, are […]
At No Magic World Symposium 2015 (NMWS2015) I presented the story about adopting MBSE using SysML in the development of Joint Strike Missile (http://www.kongsberg.com/en/kds/products/missilesystems/jointstrikemissile) at Kongsberg Defence and Aerospace. The presentation contains a hands-on description on how to organize a System Architecture Model as well as lessons learned in this adoption process.
We were delighted to be invited to speak at 31st Space Symposium tech track and present MBSE usage for highly complex projects. At sold out tech track we shared the stage with Allan Lockheed Jr. (CEO of Allan Lockheed & Associates), Dr. Gordon Roesler Program Manager at DARPA, Jeff Greason founder and CTO XCOR Aerospace, […]
A wind of changes blew two weeks ago in the OMG meeting in Reston deciding the future of Unified Profile for DoDAF and MODAF (UPDM). There were a lot of talks about OMG taking over DoDAF and renaming it to UAF; however that is not exactly the truth. DoDAF is here and OMG is not […]
The TeleManagement Forum (TMF) has been working as part of their open digital program to define REST application programming interfaces (APIs) in support of multi-partner engagements. Specifications have been created by the members of the TMF API Program and cover the following management areas: The Billing Management API provides standardized mechanisms for billing account, bill item […]
During research and development (R&D), teams often discover similarities among system components within the same or previous projects that can be reused, with the potential of saving on cost and time. The overall development effort can be dramatically reduced by reusing the different artifacts. The ability to have a repository of reusable modelling artifacts and […]
Model Based Systems Engineering (MBSE) is an emerging field of systems engineering for which the System Modeling Language (SysML) is a key enabler for descriptive, prescriptive and predictive models. This paper surveys some of the capabilities, expectations and peculiarities of tools-assisted MBSE experienced in real-life astronomical projects. The examples range in depth and scope across […]
CubeSats are a class of research spacecraft called nano satellites. The cube-shaped satellites are approximately: 10 cm long, have a volume of about 946 cm3, weigh about 1.4 kg. CubeSats are flown as auxiliary payloads on previously planned missions. MBSE for CubeSat: Generic CubeSat Reference Model and Simulation Challenge How do satellite states evolve throughout […]
The demand for support of business vocabularies in model-driven development becomes more and more evident. Yet this is being left out of focus by the majority of modeling tools vendors. Today, there are very few modeling tools which offer the functionality to manage business vocabularies and use them as an integral part of the whole […]
