Outline
In order to optimize the community emergency supplies reserve, the concept of BCM was introduced to study the multi-objective optimization model of community emergency supplies reserve. Firstly, the key services and related emergency supplies after the disaster were identified, and the community emergency support capacity was quantified by constructing the post-disaster living standard change curve. Secondly, a multi-objective optimization model for material reserves with the maximum guarantee capacity and the minimum cost is proposed. Finally, the numerical examples were solved and the sensitivity analysis of the key parameters was carried out. The results indicate that as the minimum business continuity objective increases, the level of emergency material reserves increases, enhancing the community emergency support capacity. The reserves show a priority order, with lower-cost items being increased first. Under the same level of emergency material reserves, enhancing community emergency response and handling capabilities can improve the community emergency support capacity. Moreover, as the reserves of emergency materials in a community grow, the significance of these capacities in improving the emergency support capacity becomes increasingly pronounced. The emergency material reserve optimization model constructed from the perspective of business continuity can enable the community to provide basic living guarantees for residents after emergencies.
