“…In literature, Petri-nets have also been applied to the modeling and analysis of emergency response (Aye and Ni, 2011;Meng et al, 2011;Zhong et al, 2010;Zhou, 2013;. In Zhou (2013), the emergency response process is considered as a hybrid system, and the emergency actions are divided into discrete actions and continuous actions according to their durations.…”

In industrial chemistry, many flammable materials are handled and/or stored in various facilities. It is possible that major fires occur at these facilities possibly leading to domino effects due to the failure of neighboring facilities caused by thermal radiation. It will take a certain time that thermal radiation causes nearby facilities to fail and that a domino effect occurs. The time needed for escalation to take place allows emergency actions as a response to the primary fire to prevent the propagation of the fire. In the present study, a Timed Colored Hybrid Petri-net (TCHPN) based methodology is introduced to evaluate different emergency response actions based on their efficiency in preventing or delaying the propagation of domino effects. A TCHPN model of emergency response to flammable liquid tank fire is established, and a time based analysis of emergency response actions for preventing domino effects is performed. Based on the simulation analysis, the probability of domino effects is calculated and response actions are compared.

“…The evaluation and verification of emergency response plan has been researched in many industries and fields, such as the chemical industry [19,21,23], the nuclear industry [5,9], the water pollution emergency [3,7], the earthquake emergency [1,4], and so on [2,8,10,[12][13][14]17]. However, most of these focus on emergency plan involving only single emergency organization, and no crossorganization collaborations are investigated.…”

“…However, this work does not mention how to model a collaborative emergency response process. M e n g et al [14] used Petri net to model Urban Emergency Response Systems by defining four kinds of cross-organization task coordination patterns. However, no further formal verification analysis is defined for a collaborative emergency response process model.…”

Problem statement: Automating semi-automatic dynamic machines and complex systems, where some functionalities are already automated but the machine doesn't run fully in automatic mode, represents another challenge to automating dynamic and manual complex systems. This study deals with a special case of this general problem, where the system's semi-automatic and automatic functionalities run separately in a sequence with either automatic and/or semi-automatic functionality running at any point of time, but not both. Approach: Petri-nets can successfully represent the operations of both the semi-automated and fully-automated functionalities of such dynamic systems. Three roles for the programmable logic controllers were suggested: (a) Ignoring the presence of the semi-automatic part, (b) simulating the semi-automatic part and recognizing discrepancies and(c) simulating the semi-automatic functionalities and supporting it, where the last choice was most costly and most reliable. Results: This study presents a case study for a PVC mixing dynamic process to illustrate the three suggested controller design possibilities, where a Petri net model and related ladder logic program were developed to show these three controller design options. In this respect, the semiautomatic functionality is an intermediate step between the two automated functionalities, within which an important decision should be made to end the previous automatic step and to begin the next automatic step. Conclusion/Recommendations: The automation method that was introduced in this study is applicable to a large number of machines within industrial and mechanical systems that were built using older semi-automatic control systems. Various decision analyses {DA1, DA2, DA3} were shown to produce basic choices for such types of applications. Petri-nets and ladder logic in this respect can successfully represent the operations of both the semi-automated and fully-automated functionalities, where a Petri net model and the consequent ladder logic program, used to program the utilized programmable logic controller, are developed to show three possible controller designs, where the choice between three designs depend on the designers objective of cost, reliability and fault tolerance.
