Abstract

Wood pellets have gained global attention due to their economic availability and increasing demand for bioenergy as part of sustainable energy solutions. Management of the wood pellet supply chains, from feedstock harvesting to bioenergy conversion, is critical to ensure competitiveness in the energy markets. In this regard, wood pellets supply chain coordination can play a strategic role in enhancing the efficiency and reliability of bioenergy generation. This study proposes a contract-based coordination mechanism for wood pellet supply chains and compares its performance in alternative centralized and decentralized decision-making structures. A bi-level nonlinear game-theoretic approach with two economic and environmental objective functions is developed. It utilizes the concept of life cycle assessment in a Stackelberg leader-follower game to obtain the bioenergy equilibrium solutions. Further, this study examines the case of wood pellet supply chains in three remote Canadian communities. The aim is to showcase the practicality and significance of the proposed approach and interpret the findings. By focusing on these communities, the crucial role of supply chain coordination in fostering sustainable development, particularly, in the context of bioenergy generation is emphasized. The study colludes by advocating a number of avenues for future research.

基于契约的生物能源生产木屑颗粒供应链环境经济协调博弈论方法。
木屑颗粒由于其经济可用性和作为可持续能源解决方案的一部分对生物能源的需求不断增加而受到全球关注。从原料收获到生物能源转化,对木屑颗粒供应链的管理对于确保能源市场的竞争力至关重要。在这方面,木屑颗粒供应链协调可以在提高生物能源发电的效率和可靠性方面发挥战略作用。本研究提出了一种基于契约的木屑颗粒供应链协调机制,并比较了其在集中式和分散式决策结构下的性能。提出了一种具有经济和环境两个目标函数的双水平非线性博弈论方法。它利用Stackelberg领导-追随者博弈中的生命周期评估概念来获得生物能量平衡解。此外,本研究考察了三个偏远加拿大社区的木屑颗粒供应链情况。目的是展示提出的方法的实用性和意义,并解释研究结果。以这些社区为重点,强调了供应链协调在促进可持续发展方面的关键作用,特别是在生物能源生产方面。这项研究的共同之处在于,它为未来的研究提出了一些途径。
