Abstract: Sustainable supply chain design can be performed using optimisation strategies for minimising environmental impacts while maximising profit. It is not clear how such strategies influence the resilience of a supply chain - its ability to handle disturbances without compromising its function. This research used the ecosystem network analysis (ENA) to evaluate the resilience during the design of a sugar beet supply chain. The ε-constraint method was used to solve a multi-objective, mixed integer linear programming (MOMILP) model. Results showed that ENA results are compromised when the strategy of minimising environmental impacts is used, due to the increased fragility of the configuration, compared with the configuration from the profit maximisation strategy. Sensitivity analysis also revealed that, when the number of facilities is increased, ENA results improve while profit is decreased. ENA showed an interesting potential to support the pursuit of balance between resilience and performance during early design stages.
