Unrefined and highly corrosive upstream petroleum resources and complex operating environments pose a significant threat to the integrity and safety of gathering pipelines. The present study proposed a novelty method to perform a risk assessment for gathering pipelines. The use of historical failure data developed a fishbone diagram model of hazard factors. The risk index system was developed based on the KENT method, including failure likelihood and failure consequence coefficient models. Information entropy theory was used to determine the weight of each indicator. Combined with the area-level safety design coefficient, The welding institute (TWI) method was improved to perform risk classification for different areas. The proposed method was applied to 81 gathering pipelines. Results demonstrated that the proposed method could meet the actual conditions of gathering pipelines, improving upstream energy security.

“…China’s EP experience shows that the integrated application of emerging information technologies such as 5G, the Internet of Things, big data, cloud computing, wireless communication networks, and artificial intelligence has been widely applied to respond to COVID-19. These integrated technologies break institutional and organizational constraints [ 63 ]. Having interurban multi-agent collaborative EP enhances the scientific nature of COVID-19 EP and the transparency of multi-agent collaboration.…”

To enhance the effectiveness of epidemic prevention (EP) in urban sustainability transformation, joint prevention and control mechanism should be established to prevent and control the COVID-19 epidemic. The interurban multi-agent EP strategy, as a key component of this mechanism, includes the spontaneous EP model, the superior leading EP model, and the collaborative EP model. In this study, firstly, the theoretical mechanism of the interurban multiagent EP strategy was analyzed. Then, we proposed a three-party differential game model including factors such as the risk coefficient for the virus infection and EP experience teaching. Finally, prevention strategies, prevention efficiency, and prevention losses were compared under the three models based on theoretical analysis and numerical analysis. The results of this study are as follows. COVID-19 EP should be guided by a model of central government (CG) leadership, interurban collaboration, and social participation. The CG and urban governments (UGs) should comprehensively carry out COVID-19 EP from various aspects, including EP experience teaching, mass EP comfort, the utilization rate of EP funds, and the ability to implement strategies. During the course of the COVID-19 EP, when the CG and UGs transition from spontaneous EP model to a higher-level EP model, the UG's EP efforts will be enhanced. Under the collaborative EP model, the CG and UGs undergo the highest levels of EP effort. Compared with spontaneous EP model, the superior leading EP model can promote a Pareto improvement for all parties. From the perspective of total loss, the collaborative EP model is superior to the other two EP models. This study not only provides practical guidance for coordinating interurban relationships and enabling multiagents to fully form joint forces, but also provides theoretical support for the establishment of an interurban joint EP mechanism under unified leadership.Keywords COVID-19 Á Joint prevention and control Á Urban governance Á Multi-agent collaboration Á Urban sustainability transformation Á Differential game

“…The hazard evaluation of the drive system should first determine the failure modes of the main components and the corresponding evaluation indexes, and then use the scientific evaluation method to solve the hazard degree of each failure mode. Based on the traditional evaluation indexes, in reference [3], the concept of recovery validity was introduced, which uses the analytic hierarchy process (AHP) to determine the weight of indexes, evaluates and ranks the hazard of the failure modes of the drive system of the Three Gorges ship lift, and gives corresponding conclusions. Due to its simple and clear characteristics, the analytic hierarchy process (AHP) is a widely used subjective weighting method to determine the weight of indexes.…”

As the core subsystem of the ship lift, the drive system of the Three Gorges ship lift provides power for the operation of the ship lift, and its failure will directly affect the stable and safe operation of the ship lift. In view of the shortcomings of the existing evaluation methods for the failure hazard of the Three Gorges ship lift drive system, such as strong subjectivity and unreasonable weight of evaluation indexes, a failure hazard evaluation method for the Three Gorges ship lift drive system was proposed based on combined weighting and TOPSIS method. The effectiveness and feasibility of this method are verified by simulation of the Three Gorges ship lift drive system, which provides a new evaluation method for failure hazard analysis of key components of the Three Gorges ship lift.
