A nonlinear stochastic programming model is established to maximize the availability of components. The existence conditions of the optimal preventive maintenance interval are derived, and the effectiveness of the proposed model is verified through a number of examples. 03 18 2026 03 18 2026 262 23 https://creativecommons.org/licenses/by/4.0/deed.en_US 10.37394/232018.2026.14.23 https://wseas.com/journals/cr/2026/a465106-2236.pdf Brown M, Proschan F.
