Design of Life Testing Case Study

 Today, engineering excellence must include a well-managed assessment of design reliability and validation methods.  The cars software can help you to achieve that. For example, suppose your company wants to sell a certain product, like an engine, with a sale volume of 10,000 units.  Your job is to establish an acceptable life of 50,000 miles before any major failure, wanting none of these units sold to have a major failure before 50,000 miles.  The profit if complying is $75 for each engine sold while non-compliance would produce a loss (replacement costs) of $600 if a major failure occurred before 50,000 miles.  According to these criteria, your company would like to have the profits from sales to be at least twice all replacement losses due to major failure before 50,000 miles.

Four engines are tested to a major failure and the mileages are 589,000; 793,120; 959,400, and 1,158,000 Miles.  Based on this one test of four engines, would you be able to accept the product as the one, which would comply with your desired profitability and reliability goals? If, not, what then?  The CARS  software can assist  you in determining the acceptability of your product's performance by just enter the necessary input  values --- the failure mileages and the CARS software does the rest.

In short, our CARS software  can make product development more effective and productive to anyone who demands answers quickly.  The above scenario is only a small portion of the CARS 's capability.  What this means to you, is only limited to your imagination.

  You see, the above test results show a good enough performance with 95.14% confidence.  It exceeds the required confidence of 94.12% .
