DE MARCHI, Mônica Maria; CARVALHO, Solon Venâncio de  e  MORAIS, Paulo Renato de. A stocastic model for a maintenance system based on the inspection of the produced parts. Gest. Prod. [online]. 2001, vol.8, n.2, pp.115-127. ISSN 1806-9649.  https://doi.org/10.1590/S0104-530X2001000200002.

In this paper a maintenance model is presented for an equipment deteriorating in with time. The equipment periodically produces a batch of parts. Each batch is inspected and, based on the number of defective parts, a decision about the revision of the equipment is made. The goal of the model is to obtain a maintenance policy for the equipment that minimizes the long run average cost. The cost structure includes an operation cost, a revision cost and a defective part cost. To obtain a minimum cost policy, the problem is modeled as a Markov Decision Process with Partial Information. Numerical examples are presented.

Palavras-chave : maintenance system; revision policy; Markov decision process with partial information.
