Abstract :Predictive maintenance insert ignore into journalissuearticles values(PdM); is a type of approach for maintenance processes, allowing maintenance actions to be managed depending on the machine`s current condition. Maintenance is therefore carried out before failures occur. The approach doesn’t only help avoid abrupt failures but also helps lower maintenance cost and provides possibilities to manufacturers to manage maintenance budgets in a more efficient way. A new deep neural network insert ignore into journalissuearticles values(DNN); architecture proposed in this study intends to bring a different approach to the predictive maintenance domain. There is an input layer in this architecture, a Long-Short term memory insert ignore into journalissuearticles values(LSTM); layer, a dropout layer insert ignore into journalissuearticles values(DO); followed by an LSTM layer, a hidden layer, and an output layer. The number of epochs used in the architecture and the batch size was determined using the Genetic Algorithm insert ignore into journalissuearticles values(GA);. The activation function used after the output layer, DO ratio, and optimization algorithm optimizes loss function determined by using grid search insert ignore into journalissuearticles values(GS);. This approach brings a different perspective to the literature for finding optimum parameters of LSTM. The neural network and hyperparameter optimization approach proposed in this study performs much better than existent studies regarding LSTM network usage for predictive maintenance purposes.
