Abstract
This paper proposes a whole cycle analysis method of supply chain disruption based on underwater acoustic sensor networks (UASNs). Firstly, the UASNs are deployed to monitor offshore disruptions (such as oil leakage), and the monitoring data of underwater disruptions can be obtained. Based on the monitoring data, scenario inference and Bayesian network forecasting are applied to reversely infer the upstream causes and probabilities of the disruption, which will provide decision-making basis for the effective prevention of such disruptions in the future. At the same time, based on the monitoring data via UASNs, the DA-NET model of the petroleum supply chain (PSC) system is built and the impact of the disruption on PSC operation is analyzed quantitatively, such as cost increase or time delay. The results show that with disruption monitoring via UASNs, the proposed method can not only infer the causes of a disruption, but also quantitatively determine the impact of the disruption on the operation of PSC, which has certain guiding significance for the enterprise managers of the PSC to prevent such disruptions in advance and to deal with them afterwards.
Highlights
Underwater acoustic sensor networks (UASNs) consist of a variable number of sensors and vehicles that are deployed to perform collaborative monitoring tasks over a given sea area
Oil leakage can result in serious contamination of the ocean and shoreline environment and bring huge loss to the enterprises of petroleum supply chain (PSC)
6 Conclusion UASNs present a golden opportunity for marine disruption analysis
Summary
Underwater acoustic sensor networks (UASNs) consist of a variable number of sensors and vehicles that are deployed to perform collaborative monitoring tasks over a given sea area. UASNs have become more and more important in ocean exploration applications, such as ocean monitoring, pollution detection, ocean resource management, and underwater device maintenance [1]. As a kind of strategic material, petroleum is significant for the industrial economy and national defense of a country. The uncertain nature and high economic incentives of the petroleum business are driving forces for improvements in the supply chain management. About 80% petroleum is transported by sea. Oil leakage can result in serious contamination of the ocean and shoreline environment and bring huge loss to the enterprises of petroleum supply chain (PSC).
