区块链使能石油工程质量四方主体演化博弈分析

Evolutionary Game Analysis of Blockchain-enabled Petroleum Engineering Quality with Four Parties

针对石油石化建设工程中存在的稳定性差、质量安全事故频发、多方协作程度低等问题,以石油工程质量管理为研究对象,对影响工程质量参与主体决策的因素进行分析,构建建设单位、监理单位、供应商单位、施工单位四方演化博弈模型,分析了四方策略选择的相互作用,运用MATLAB仿真模拟探索各主体博弈策略演化的规律,通过调整区块链技术引入前后的参数设置分析四方策略对重要参数的敏感性及区块链解决石油工程质量问题的作用机制。结果表明:区块链技术的引入有助于解决信息不对称的问题,提高主体之间的信任度,降低合谋风险;为石油工程营造了更加严格的监管环境,降低监督成本的同时提高监督效率,有效遏制了机会主义行为的产生;丰富并完善了工程质量管理体系,推动石油行业智能化进程的转型升级。

Aiming at the problems of poor stability,quality and safety,and low degree of multi-party cooperation in petroleum and petrochemical construction projects,taking petroleum engineering quality management as research object,the factors that affect engineering quality participating in the decision-making of the main bodies are analyzed,and a four-party evolutionary game model of construction unit,supervision unit,supplier unit and construction unit is established.The interaction of four-party strategy choices is analyzed,and the evolution of game strategies of each party is discussed using MATLAB simulation.The sensitivity of the four party strategy to important parameters and the mechanism of solving the quality problems of petroleum engineering using the blockchain are analyzed by adjusting the parameter settings before and after the introduction of the blockchain technology.The results show that the introduction of blockchain technology helps to solve the problem of information asymmetry,improves the trust among subjects,and reduces the risk of collusion;it creates a stricter supervision environment for petroleum engineering,reduces the cost of supervision while improving the efficiency of supervision,and effectively curbed the emergence of opportunism;it enriches and improves the engineering quality management system,and promotes the transformation and upgrading of the intelligent process of the petroleum industry.
