Performance Measurement System (PeMS) is a freeway performance measurement system for all of California. It processes 2 GB/day of 30-s loop detector data in real time to produce useful information.
This approach will help resolve what has been a long-standing challenge for many mining companies: making productivity performance (and its measurement) a priority. Operators have typically concentrated on improving one or two variables, such as reducing cost, lowering capital intensity, or increasing throughput.
The process of constructing the unascertained measurement model of thermal humidity risk under high temperature underground conditions is shown in Fig. 1.Using the unascertained measure theory, a comprehensive evaluation was carried out on the basis of various factors that caused underground workers to respond to the thermal stress, and the risk …
