- Additional information
- Novel theory with practical application in cases where is it is not feasible to undertake long-term statistical testing of an entire safety-critical system. The test allocation theory is general, and can be applied to any system architecture. It is currently being used to optimise the statistical test programme for a nuclear reactor protection system (a multi-million pound test project). The new test allocation approach allows an order of magnitude improvement in claimed software reliability compared with the original test plan. The industrial statistical test leader contact can be provided to REF by City University.
