var fDesc=new Array(); fDesc[0] = "The RiskVu computer program provides a high level interface to the FaultTree program allowing system designs to be compared by personnel with no experience in fault or event tree analysis methods.

Fault tree and event tree analysis methods are widely applied to system availability and reliability problems in most engineering disciplines. They may be used to predict the performance of a system at various stages of the design process and indicate reliability weak spots in the design.

Experienced reliability engineers may modify the structure of the fault and event trees in order to compare predicted system performance from different design options. The computer program FaultTree is used by thousands of engineers to hold the fault and event tree data, analyze the system, and report on the results."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
