CAiRS webinar - How Products Reliability and Systems Safety help Local Industry

 The webinar named “How Products Reliability and Systems Safety help Local Industry to address market needs and promote business opportunities” was organized by Centre for Advan es in Reliability and Safety (CAiRS) and supported by HKSTP on 26th Nov 2020.  It aimed to share industrial and research experiences on products reliability and systems safety and how the industry needs could be addressed and business opportunities could be promoted. 


Prof. Winco Yung (Centre Director, CAiRS) was the first speaker and his topic entitled “Introduction of Reliability and Safety Research in CAiRS”.  Firstly, Prof. Yung mentioned the vision of CAiRS that aimed to be world leading and regional hub for research in reliability and safety innovation.


And then he introduced CAiRS approach in which focused on AI based methods for system health assessment so as to ensure reliability and safety. It aimed to develop a real-time and predictive solution for system safety.  


After that Prof. Yung introduced five key research programs for achieving their objectives below.

l   Identification and acquisition of useful data relating to reliability and safety.

l   Development of different AI technologies in bridging the above knowledge gaps and formation industry big data

l   Integration of Data-driven Model and Physics of Failures approaches on data set in various industry sectors

l   Development of algorithm for Predictive Failure of critical components and systems

l   Formulation of practical modelling on product’s life prediction and process quality forecast


Finally, Prof. Wu stated their testing laboratory capabilities included AI supercomputing, Temperature & Environment Testing, Failure Analysis Equipment and Life Cycle Assessment Equipment. Moreover, he also introduced their team member in different departments in PolyU with different supporting organizations such as HKEIA, HKEIC, ASM, Compass, nVidia, HAECO, CLP, GP, Defond, … etc.


Lastly, Prof. Wu emphasized several benefits to collaborate between Industry and CAiRS such as failure prevention and cost saving.  Until now, there were five application sectors in the program and they were Transportation, Public Utility, Products, Parts & Components, and Data Integrity & Software Trustworth.


Dr. Brian Li (Executive VP, Gold Peak Industries (Holdings) Limited) was the second speaker and his presentation named “Marketing Needs and Challenges of Products Reliability and Systems Safety”.  In the beginning, Dr. Li briefed the background of Gold Peak Group.


Then Dr. Li mentioned the product quality and reliability that was the livelihood of a manufacturer.  He said that the integral cost of supplying products to customers included customer service costs and warranty costs, which could be higher than the manufacturer’s Free On Board (FOB) cost in terms of brand.  Therefore, high quality and high reliability is a most important qualification to establish the brand.  After that he briefed their group’s batteries was working with CAiRS on new approaches for assessing product reliability using Big Data analysis and AI techniques.


Finally, Dr. Li briefed their GP batteries service and requirements.  He expected the best quality and reliability were achieved before new product launch through new technology and research employed from the program with CAiRS.


The last speaker was Dr. Steven Boles (Associate Professor, PolyU) and his presentation title was “Reliability and Safety Research Methodology with Industrial Applications”. Firstly, he briefed the demand trend for energy.  Electricity increasing daily was observed that Natural Gas and Renewables were growing.


Then Dr. Boles said we needed for energy storage using electrochemical energy storage device.  It was observed that Lithium-ion Battery (LIB) was growing in recently years. 


After that Dr. Boles briefed the principles of LIBs and said more energy stored, the higher risk was.  Therefore, safety and reliability of LIBs were concerned especially travelling in fight (e.g. spare lithium batteries never go in a checked bag).  


Finally, Dr. Boles briefed some cases about “Physics of Failure” in LIB such as Li-metal plating, Overcharging, Manufacturing issues, thermal runaway, etc.  Therefore, he suggested to add sensing in batteries like “canary” device so as to improve safety, reliability and health in the future.
