The actual data should be Received January 10 2018 modeled then it could be used for the prediction process. In this paper 996 airplane maintenance Received in revised format April basis data are used as a database and 119 similar data are chosen after clustering. The project is 1 2018 divided into 20 equal periods and first three periods are used for simulating the next point. The Accepted June 8 2018 Available online predicted data for each point is achieved by using of previous points from the beginning. The June 9 2018 model is based on artificial neural network and it is trained by three algorithms which are Ge- Keywords netic Algorithm GA Estimation of Distribution Algorithm EDA and hybrid GA-EDA Cash flow method. Two dynamic ratios are used which are dividing the population into two halves and the Neural network other is a ratio without dividing. The ratio would give a proportion to GA and EDA models in Genetic algorithm the hybrid algorithm and then the hybrid algorithm could model the system more accurately. Estimation of distribution algo- For each algorithm three main errors are calculated which are mean absolute percentage error rithm MAPE mean square .
