【摘要】：成品油二次配送作为危险品运输研究领域的一个典型应用,除了具有一般危险品运输的特征之外,其配送风险还具有自身的特殊性,需要根据配送情境进行多维考虑。针对这一具体问题,依据公众风险偏好选择合适的道路风险模型,加入二次配送道路风险的动态变化特征,使其更加符合现实配送情境;引入脆弱点风险概念,建立兼顾脆弱点规模和受影响距离的脆弱点风险优化模型,进一步丰富成品油二次配送风险内涵;综合考虑配送成本和风险,构建最小化运输成本、道路风险和脆弱点风险的多目标整数规划模型,运用层级搜索算法求解,有效避免了多目标规划的系数决策困境。数值实验表明,该模型能够在企业可接受的成本范围内,有效降低配送过程中的道路风险和脆弱点风险。
[Abstract]:As a typical application in the field of dangerous goods transportation, the secondary distribution of refined oil has its own particularity in addition to the characteristics of general dangerous goods transportation. According to this specific problem, according to the public risk preference, select the appropriate road risk model, and add the dynamic characteristics of the secondary distribution road risk. Make it more in line with the reality of distribution situation; This paper introduces the concept of vulnerability point risk and establishes a vulnerability point risk optimization model which takes into account the vulnerability point scale and the affected distance to further enrich the risk connotation of secondary distribution of refined oil products. Considering the distribution cost and risk, the multi-objective integer programming model of minimizing transportation cost, road risk and vulnerability point risk is constructed, and the hierarchical search algorithm is used to solve the problem. Numerical experiments show that the model can effectively reduce the road risk and vulnerability point risk in the distribution process within the acceptable cost range of the enterprise.
