Abstract: Selective maintenance strategy and cannibalization maintenance strategy are two very important equipment maintenance strategies. The paper develops a selective maintenance model considering cannibalization and multiple maintenance actions, moreover it extends the selective maintenance model at system definition, mission definition and maintenance resource. Firstly, it expounds on the model assumption. Then, it establishes a non-linear, 0-1 programming model to resolve the selective maintenance problem considering cannibalization and multiple maintenance actions. Next，the paper presents a algorithm framework based on metaheuristics. Finally, it provides an example to verify the validity and feasibility of the model. The model suits manager to make reasonable decision considering cannibalization and multiple maintenance actions.
