Construction of Conflict-Free and Efficient Cross-Organization Emergency Response Processes

Ver documento

Detalhes bibliográficos
Resumo:Usually, the disposal of the emergency is organized as a cross-organization emergency response process (CERP), where various resources are involved. The lack of these resources may cause resource conflicts that can delay or even suspend the CERP, thereby increasing the risk imposed on life, property, and the environment. In this paper, we propose a novel approach to construct conflict-free and efficient CERPs. This approach first presents a branching place-based method to decompose a CERP into a set of execution paths. In essence, an execution path refers to a process fragment without choice structures corresponding to some kind of process instance in the CERP. In practice, each execution of the CERP can only follow such an execution path. Next, it determines whether each execution path contains resource conflicts. If not, then the execution path is considered conflict-free; otherwise, it will be resolved using a delay-based strategy. Lastly, it introduces an execution path-oriented strategy to merge all originally conflict-free and resolved execution paths to form a resolved CERP, in which each execution of it is conflict-free and efficient. The proposed approach is implemented in the tool RCTool, and a group of experiments conducted on actual CERPs demonstrates that it is more effective in constructing conflict-free and efficient CERPs compared to existing proposals, and its computation overhead is also acceptable in practice.
