Abstract: Existing supply chain designs focus on efficiency and cost minimisation, particularly in just-in-time (JIT) systems. At the same time, sustainability requires designs that preserve resources and minimise environmental impact; thus, companies should design their supply chains to be simultaneously flexible, sustainable, and efficient. This study proposes a genetic algorithm-based optimisation model to address the trade-off between the total supply cost and the carbon emission cost during supply network disruption. The model is tested using a case study to validate its applicability using the particle swarm optimisation (PSO) approach. A number of factors are analysed: lead time, order quantity variance, and transportation mode selection. Performance variables include the total supply chain cost which comprises production, transportation, and CO₂ costs. The model has many opportunities for application where the supply chain is disrupted, such as in the recent pandemic, especially when companies do not want to compromise efficiency and sustainability.
