Data in probabilities assessment

Data in probabilities assessment constitute an everyday conundrum. The key question is what constitutes essential (understood as basic, indispensable) and ideal (understood as “perfect”) data set. There is no “simple” answer to that question. Consider that we often deal with prototypes or new facilities before commissioning. Past performances may not reflect future behavior because of system or climatic changes. Indeed, any internal or external change to the system has the potential to prove assumptions wrong. In particular, that past experiences…

Convergent Quantitative Cyber Risk Assessment to Optimize Enterprise Reliability

.Convergent Quantitative Cyber Risk Assessment to Optimize Enterprise Reliability will be the theme of our paper at CIM 2018 conference. Reportedly KPMG’s Toronto office produced a text entitled “Insights Into Mining” stating that mining companies “may be” underestimating the risk of cyberattacks. Indeed they consider this risk will increase as more companies embrace mining automation, IoT, etc. The report also emphasizes that mining executives believe based, like usual, on “feeling and perceptions”  that innovation and the risk of disruption are…
