Purpose - The purpose of this paper is to propose a model that captures the fuzzy events is proposed to find the optimal periods of warranty policies. The model considers repair and replacement actions in the warranty period. Design/methodology/approach - The study transforms the reliability of a traditional set to a fuzzy reliability set that models a problem. The optimality of the model is explored with classical optimal theory. Also, a numerical example is presented to describe how to find an optimal warranty policy. Findings - The study proves that the optimality of a warranty model can be used to find the optimal warranty policy in a fuzzy environment. Originality/value - The model is useful for firms in deciding what the maintenance strategy and warranty period should be in a fuzzy environment.
