Subject: One-Shot Device Reliability Analysis
Message:
Hi, Is there any way to do an analysis or prediction on a one shot device? I realize that the binomial theoreum can be used to estimate reliability at a specified confidence level if you have test data. However, we are trying to build an undersea (depth = 1200 feet) cable cutter (has electronics and hydraulics) that sits for as many as 30 days and then is exercised. Thus multiple real life tests of this would be extremely long and expensive. Also, any ideas on how we could acclerate the test time? Thanks in advance. Bob Valerius
