Qhov "Safety Factor" yog kab tias feem ntau tsis to taub tus lej hauv kev lag luam nruj. Nws tsis yog "xav" ntawm lub zog, tab sis suav nrog qhov tshwm sim ntawm kev muaj sia nyob raws li kev ua qauv kev pheej hmoo dynamic. Hauv kev lag luam xaim hlua, peb siv cov spectrum ntawm qhov sib piv-los ntawm 3: 1 rau qhov zoo li qub rau 10: 1 rau cov neeg caij elevator-txhua qhov cuam tshuam txog qib sib txawv ntawm kev ua haujlwm tsis paub meej.

Lub hauv paus ntawm Uncertainty:

Ib qho kev nyab xeeb ntawm 5: 1 rau kev nqa dav dav xav tias txoj hlua yuav ntsib yam tsis tau xav txog: microscopic sheave misalignment, sib txawv acceleration curves, thiab inevitable ingress ntawm corrosive pollutants. Qhov piv 5: 1 ua kom ntseeg tau tias txawm tias txoj hlua poob 20% ntawm nws tus ntoo khaub lig- ntu ntu los ntawm kev hnav, nws tseem nyob hauv thaj tsam ntawm kev nyab xeeb ntawm cov qauv.

Modeling the Human Risk:

Rau cov neeg caij tsheb thauj mus los, qhov tseem ceeb yog ob npaug rau 10: 1. Qhov no qhia txog qhov "Xero-Kev Tolerance" ib puag ncig ntawm cov tsev skyscrapers hauv nroog. Qhov nce ntxiv tsis yog vim txoj hlua "tsis muaj zog," tab sis vim tias qhov ua tsis tiav yog qhov tseeb. Ntawm SOLITE, peb pab peb cov neeg siv khoom hauv kev ua "Dynamic Safety Audits," qhov uas peb suav cov kev cuam tshuam tshwj xeeb ntawm lawv cov tshuab kom ntseeg tau tias qhov kev xaiv kev nyab xeeb yog nyob rau hauv qhov tseeb physics, tsis yog kev lag luam kev lig kev cai. Kev nyab xeeb yog kev tshawb fawb ntawm qhov tsis txaus ntseeg.
