当代流程工业面临着动荡的市场状况，这危及它们的财务可持续性。虽然成熟的市场，如工业气体，向寡头垄断结构过渡，但供应链运营应适应更多以客户为中心的重点。与公司与客户之间相关合同协议的模式和影响有关的关键问题在很大程度上仍未得到探讨。在这项工作中，我们研究了工业气体市场寡头垄断企业在多个时期内不同合同协议下的公平客户分配问题。我们考虑的合同类型在定价和期限方面各不相同。在社会福利和纳什讨价还价方案之后，对公平的作用进行了研究。在后一种情况下，整个问题被表示为基于特殊有序集线性化的MINLP。通过两个来自工业气体市场的案例研究，评估了不同公平方案对最优客户分配的影响。
Contemporary process industries are confronted with volatile market conditions that jeopardise their financial sustainability. While mature markets, e.g. industrial gases, transition to oligopoly structures, the supply chain operation should adapt to a more customer-centric focus. Key issues related to the modelling and impact of the related contractual agreements between firms and customers remain largely unexplored. In this work, we examine the problem of fair customer allocation in industrial gases market oligopolies under different contractual agreements within a multi-period setting. We consider an ensemble of contract types that vary in terms of pricing and duration. The role of fairness is examined following the social welfare and Nash bargaining scheme. In the latter case, the overall problem is formulated as an MINLP that is linearised based on special-ordered sets. The impact of the different fairness schemes on the optimal customer allocation is evaluated via two case studies from the industrial gases market.
