Abstract

Supply chain disruption can occur for a variety of reasons, including natural disasters or market dynamics for which resilient strategies should be designed. If the disruption is profound and has dire consequences for the economy, it calls for the regulator’s intervention to minimize the impact for the betterment of the society. This paper investigates the minimum quota regulation on transport amounts of a shipping company with limited capacity that transports a group of products with heterogeneous transportation and production costs and prices. An interesting example can be found in the North American rail transportation market, where rail capacity is used for a variety of products and commodities, such as oil and grains. Similarly, in Europe, the supply chain for grain produced in Ukraine is disrupted by the Ukraine war and the blockade of the maritime transport routes. This siege puts pressure on the rail transport capacity of Ukraine and its neighboring countries to the west, which needs to be shared to ship a variety of products, including grains, military, and humanitarian supplies. Such situations require the proper execution of government intervention for effective management of limited transport capacity to avoid rippling effects throughout the economy. We propose mathematical models and solutions for market players and the government in a Canadian case study. Subsequently, the conditions that justify government intervention are identified, and an algorithm is presented to obtain the optimum minimum quotas.

通过平衡定价和规定运输配额监管提高供应链的弹性
供应链中断的原因多种多样,包括自然灾害或市场动态,应针对这些原因制定弹性战略。如果中断严重并对经济造成严重后果,则需要监管机构进行干预,以尽量减少影响,改善社会。本文研究了一家运力有限的航运公司对运输量的最低配额监管,该公司运输的是一组具有不同运输和生产成本及价格的产品。北美铁路运输市场就是一个有趣的例子,铁路运力用于运输石油和谷物等多种产品和商品。同样,在欧洲,乌克兰战争和对海上运输路线的封锁扰乱了乌克兰生产的谷物供应链。这种封锁对乌克兰及其西面邻国的铁路运输能力造成了压力,而这些能力需要共享,以运输包括谷物、军事和人道主义物资在内的各种产品。在这种情况下,政府必须采取适当的干预措施,对有限的运输能力进行有效管理,以避免对整个经济产生连锁反应。我们以加拿大为例,为市场参与者和政府提出了数学模型和解决方案。随后,我们确定了政府干预的合理条件,并提出了一种获得最佳最低配额的算法。

期刊介绍: Omega reports on developments in management, including the latest research results and applications. Original contributions and review articles describe the state of the art in specific fields or functions of management, while there are shorter critical assessments of particular management techniques. Other features of the journal are the "Memoranda" section for short communications and "Feedback", a correspondence column. Omega is both stimulating reading and an important source for practising managers, specialists in management services, operational research workers and management scientists, management consultants, academics, students and research personnel throughout the world. The material published is of high quality and relevance, written in a manner which makes it accessible to all of this wide-ranging readership. Preference will be given to papers with implications to the practice of management. Submissions of purely theoretical papers are discouraged. The review of material for publication in the journal reflects this aim.
