How important is reliability for you?

Every product builder wants to avoid unexpected failures of his products when in operation. However, there is so much that can be said about the reliability of products and how to improve or guarantee it. We would like to know which topics are on your mind? Let us know and receive our practical step-by-step plan to draw up the life-cycle profile of your products.

In order to guarantee, or even improve, the reliability of a product, you can take one or more of the following actions:

  • Improve your knowledge of the life-cycle profile (which describes the loads your product will have to withstand throughout its lifespan)
  • Perform process, concept and design FMEAs to detect the critical points of your products (which may be the cause of failure modes, with potentially major effects on product reliability)
  • Build virtual prototypes and perform simulations to reveal any critical points
  • Use analytical physical failure models (‘physics of failure’) to predict failure modes and lifespan
  • Subject physical prototypes to limit and lifespan tests to detect critical points
  • Monitor the environmental circumstances and/or properties of the product, during the operation, to detect overload and wear and link the necessary actions (such as predictive maintenance instead of corrective - too late - or preventive - too early)
  • Build in adaptive control in the design allowing the product to react to measured environmental and product conditions and which allows it to protect itself against overload.
Which aspects are important to you? In which areas would you like additional training or support? Let us know in this short survey! In the second half of the year we will organise a seminar about the topics of your choice. In the meantime you will receive our 'Life-cycle profile guideline', a practical step-by-step plan to draw up a life cycle profile.

Life cycle profiles  

If you want to do things more efficiently, you should take into account the expected loads on the product caused by its environment in all life phases (transport, use, ...) starting from the design phase. A life-cycle profile describes these loads that will affect your product throughout its lifespan. It is important to conduct this analysis up front since you will need this information to make your product reliable, safe, easy to maintain ... from the design phase.  

For existing products in new environments the life-cycle profile makes it possible to determine which design adjustments or other measures have to be taken to meet the requirements of your customer or the law. 

The 'Life-cycle profile guideline' written by Sirris will give you a process to follow and tools to prepare this life-cycle profile. The guideline shows you in four big steps how to identify the relevant phases in the life cycle, their situations and their loads. This step-by-step plan is a tool to support product designers in their aim for reliable products. This approach can be applied to any product, destined for any market.  

After filling in the survey you will get access to the guideline.
