Calibration of a fuzzy model estimating fire response time in a tunnel
Popis výsledku v původním jazyce
Safety is one of the most important aspects when designing a road tunnel system. Apart from the general design of a road tunnel, different technological safety systems can contribute to increased safety. There is, however, no agreed methodology on how to evaluate such systems prior to their design and installation. In this paper, it is recommended that the time required to detect a fire and warn people about it in the tunnel be used as a quality criterion since it has a direct effect on the probability of saving lives. In their previous paper, the authors proposed a fuzzy system called SAFECALC for effectively evaluating fire sensors and warning systems in tunnels, even in the early design phase. The biggest challenge in designing a fuzzy system is the original identification and calibration of such a system. For that reason, this paper focuses on the identification stage and, using the example of a linear fire sensor, it suggests a new methodology for performing such early level calibration. This methodology consists of several steps and, after the original design of the system, it uses inputs provided by experts in the field (via surveys and brainstorming) for fine tuning of the system. A physical model is used to simulate the propagation of a fire in a tunnel. The results of such the process are then evaluated on a real world case study from Lochkov tunnel near the city of Prague.
