In many cases:• Sensors: collect data regarding the state of the mechanical system

(engineering analysis)• Control modules: using the sensor information compute the necessary

actuation to advance the mechanical system in the desired state• Actuators: apply the (mechanical) loading (e.g., electric motors, hydraulic

pistons) computed by the control modules.

The mission of the Systems Modeling & Simulation Working Group (SMSWG) is to:• develop a vendor-neutral, end-user driven consortium• promote the advancement of the technology and practices associated with co-simulation of systems engineering and engineering analysis• act as the governing body of standards in this space• drive the strategic direction for technology development in this space

This includes education, communication, promotion of standards, and development of requirements that will have general benefits to the simulation and analysis communities.

The Event

 The following individuals participated in the Collaboration Kick-Off call on August 18, 2011 where an agreement in principle was made to proceed with forming a sub-committee to develop recommendations for mutual collaboration.

The NAFEMS Representatives were as follows:

Tim Morris, NAFEMS Chief Executive

Michele Ringrose, NAFEMS North American Representative

Rodney Dreisbach, NAFEMS North American Steering Committee Chairman

Edward Ladzinski, NAFEMS North American Steering Committee

 

The INCOSE representatives were as follows: 

Samantha Robitaille, INCOSE President

John Thomas, INCOSE President Elect

Jean-Claude Roussel, INCOSE Technical Director

Ralf Hartmann, INCOSE Director for Strategy

Holly Witte, INCOSE Executive Management

Vision of the SMSWG

Manufacturers in all industries face a number of challenges, including increased product complexity and a need to reduce time-to-market. Among the most difficult challenges are promoting collaboration among multiple engineering disciplines, integrating complex systems engineering processes, and enabling the sharing of intellectual property among globally dispersed teams, among companies and industries. At the same time, costs must be tightly controlled while still ensuring that performance objectives can be met.

To address these areas of concern, INCOSE/NAFEMS has established the Systems Modeling & Simulation Working Group (SMSWG). The SMSWG will define best practices and standards for vendors to develop and manufacturers to follow the merging of engineering analysis with the overall systems behavior analysis to perform more realistic, accurate, and lifelike experiences. Successful execution will result in new opportunities for industries to fundamentally transform their business processes and reduce development cycle time and cost by providing an upfront optimization of the product for the complete product life cycle.

Actions of the SMSWG

• Implementation of a joint cross organizational WG on “Systems Modeling and Simulation”– NAFEMS to launch a new international Technical Working Group (TWG) "Systems Modeling and

Simulation"– INCOSE to launch a new WG "Systems Modeling and Simulation"

• INCOSE to integrate Engineering Analysis and Simulation within the Model Based System Engineering initiative

• NAFEMS and INCOSE to offer jointly "Systems Modeling and Simulation" focused events and to stimulate cross fertilization

• NAFEMS and INCOSE to provide mutual assistance and support for international standards• NAFEMS and INCOSE to co-develop Working Groups on the topic of "Systems Modeling and

Simulation"• NAFEMS and INCOSE to mutually support specific, non-funded, events of each organization. Events

to be determined but to include: NAFEMS World Congress, INCOSE Symposium. Such support will include invitations to each organization’s meetings on subjects of mutual interest

• NAFEMS and INCOSE to develop a joint approach for interfacing with other organizations in related professional areas

• NAFEMS and INCOSE will each name a representative who will act as a liaison between each organization

Logical-Physical Co-Simulation

• Goal: provide a comprehensive, easy to use capability of modeling system level behavior

• How: Co-simulation between Dynamic Modeling and Engineering Analysis• Model the physics in the system such as mechanical, thermal,

acoustics, etc. Provides sensors and actuators. • Model electronics, hydraulics, pneumatics of the system

Co-simulation

Probabilistic Certificate of Correctness (PCC)

• PCC has three ingredients:– Probability of satisfying requirements– Confidence in probability of satisfying

requirements, expressed as a confidence level and confidence interval:

• 97.5% confident that:– Range = 3500km ± 1200km > 1000km– P(Range > 1000km) = 98.8% - 2.2% >

90%– Verified set of assumptions

• Known model accuracy, units, etc.• Limits of mathematical model• Performance envelope and conditions

High success probability, but assumptions violated
