Sociotechnological Systems Engineering Summary of the Gordon Center Seminar Day,

January 14th, 2020Avigdor Zonnenshain,

The Gordon Center for Systems Engineering, Technion

[email protected]

Opening & IntroductionThetraditionalsystemsengineeringday,inmemorialoflateDr.YossiLevine,wasconducted

onJanuary14th,2020attheGordonCenter,Technion,Haifa,withtheparticipationofabout250

people.ThedaywasdedicatedtoSociotechnologicalSystemsEngineeringaccordingtothegreat

interestininnovativesystemsengineeringfordesigningcomplexsystems.Thiskindofsystems

engineeringcallsfornewopportunitiesandchallenges.

Prof. Yossi Ben Asher, the head of the Center, Dr Irit Idan from RAFAEL, Eli Israeli from IAI, Dr. Ram Oron the president of INCOSE_IL, and Assaf Levine addressed the forum. two systems engineers – one from RAFAEL and one from IAI – awarded as “best systems engineers of the year”.

Sociotechnological Systems Engineering – Challenges and OpportunitiesThe currently evolved technological, organizational, business, social and political ecosystem happen to be overly complex. It is claimed that for such an ecosystem a different system engineering is needed, which should consider the various aspects mentioned above. It is proposed to call it Sociotechnological Systems Engineering.

The Challenges and Opportunities of Sociotechnological Systems • John GillDr John Gill developed a proposed framework for sociotechnological systems engineering and pre-sented it in a paper in the previous issue (January 2020) of The Voice of the Systems and in this talk.

The essential elements of the proposed framework are described in the following diagram:

It is also suggested to include in this framework innovative approach for business model for socio-technological systems named BMI (Business Model Innovation).

The Story Behind SpaceIL and the Social and Technological Challenges of the BERESHEET Mission • Asaf LewinThis initiative was a technical-social project from the beginning. It started as a youth education pro-gram in Israel towards STEM studying through the mission and the challenge of BERESHEET - an attempt to develop a light unmanned space vehicle that will land on the moon. Asaf described the education achievement of this project and the level of enthusiasm towards STEM studying that this project generated. He also described the innovative and creative approaches that were applied in the technical mission, such as a mission without a Rover, using others launching mission for delivering BERESHEET spacecraft with very economical budget (under 100M $).

Engineering Lessons from the BERESHEET Mission • Yoav LandsmanYoav Landsman was the system engineer of BERESHEET mission. Yoav presented the processes of engineering, integration & building of the spacecraft and of the planning & the flying of the spacecraft. Yoav also shared in his talk the engineering insights from the mission.

NASA’s Major Disasters - Insights for Risk Management • Yossi ZamriYossi Zamri from M4T described lessons learned and insights from the failures that caused the de-sasters of Challenger and Columbia. Based on these, insights abought risks management of complex program were presented. Some of the insights are: Be aware of the syndrome “our case is different”, the victims of the clash between a powerful management and innocent engineering, etc.



SociotechnologicalSystemsEngineeringSummaryoftheGordonCenterSeminarDay,January14th,2020

Table Of Contents

Socio-Technical Integration Challenges • Sergey TozikSergey Tozik presented the application of two theories, based upon management, organization and social sciences, for designing and implementing sociotechnological systems: The Actor-Network Theory (ANT) and the Organizational Routine Theory.

The Challenge of Integrating Human Engineering into the Safety Certification Process of AR/VR Systems • Ron NaumanRon Nauman is the senior architect of the aircraft division at Elbitsystems. In his talk Ron presented how to integrate human engineering aspects into the design, engineering , testing and certification of Virtual/Augmented Reality (VR/AR) systems.

Measuring Structural and Functional Complexities • Alon Ben MosheAlon Ben Moshe from RAFAEL presented his research master thesis at the Technion. Alon developed methodologies for measuring and evaluating of structural and functional complexities of equivalent mechanical systems. These methodologies can be helpful for the systems engineers when selecting appropriate engineering concept.

Implementing Electric Vehicles System in Israel • Idan LiebesIdan LiebesfromtheNeamanInstituteattheTechnionpresentedapproachesandprocessesfor

implementingchargingsystemsforelectricalcarsinIsrael.Suchchargingsystemsdemonstratesocio-

technologicalsystemsastheyinvolvetechnical,socialandenvironmentalaspectsandconsiderations.

Systems Engineering for the Fourth Industrial Revolution • Book announcementThis book is the initiative of its three editors: Prof. Ron Kenett, Dr. Avigdor Zonnenshain and Prof. Robert Swarz. The book holds 22 chapters written by 30 international experts. Ron presented the goals of the book for researchers, teachers, practitioners, students, and systems engineers, and mentioned the intention to prepare a study guide for the book based on case studies. Six of the Israeli contributors (Amir Tomer, Avi harel, Yair Shai, Arnon Katz, Eitan Adres and Nirit Gavish) presented shortly their chapters.
