Dispatching firefighting resources effectively plays a vital role in wildfire management. To control the fire timely manner, should be dispatched an effective and reasonable way. Moreover, relationship between various resource-dispatching processes intuitive for firefighters to make decisions. In this paper, we propose novel event-response tree-based model dispatch different kinds of based on s...

In most industrial processes, vast amounts of data are recorded through their distributed control systems (DCSs) and emergency shutdown (ESD) systems. This twopart article presents a dynamic risk analysis methodology that uses alarm databases to improve process safety and product quality. The methodology consists of three steps: (i) tracking of abnormal events over an extended period of time, (...

Time series analysis can identify outliers in tree-ring widths that may not only indicate past disturbances, but may also estimate the subsequent effe cts of these disturbances on tree growth. Findin g a way to isolate these disturbance signals from tree-ring time series could have broad applications in forest ecology and management. Time series outliers may be expressed as pulse, step, or tren...

Probabilistic seismic risk assessments (PSRA) are used to quantify the seismic damage probability of complex engineering structures due to seismic events. In such systems, the seismic capacities of individual relevant components are determined by structure mechanics. A significant digits computation method to quantify the mean seismic failure probability (fragility) for given component capacity...

Fault tree analysis is often used to assess risks within industrial systems. The technique is commonly used although there are associated limitations in terms of accuracy and efficiency when dealing with large fault tree structures. The most recent approach to aid the analysis of the fault tree diagram is the Binary Decision Diagram (BDD) methodology. To utilise the technique the fault tree str...

Chemical Process Plant as a complex system requires good scientific knowledge on different issues including Process Safety Analysis (PSA). Fuzzy logic is the collective name for “Fuzzy set analysis” and “Possibility theory”, able to use random or approximate data in the Process Safety Analysis. This paper explains the impact of fuzzy set theory for basic tools used in Process Safety Analysis. I...
