Every day, the water supply network evolves to fix or prevent leaksor contaminated drinking water, and hook-ups to buildings are set up or removed. Most technical interventions are planned in advance, but emergencies can abruptly disturb the planning. This work intends to propose a methodology to evaluate various planning strategies in order to maximize the resilience and efficiency of the water supply network scheduling. An industrial application is developed on a large French water management company. The baseline of this case is the existing planning process observed in the field. Then, based on a literature analysis, a set of alternative planning processes when removing some constraints. The proposed methodology allows to comparethe existing solution to these alternatives. Finally, as the research is in its infancy, the paper develops avenues for future research through a specific research agenda.
