The Sum of Values from a Non-normal truncated and a Normal distribution: This concerns the estimation of the probability distribution of the sum of a non-normal truncated with a normal random variable. An efficient and effective computational method is proposed to solve the problem. Experiments involving stochastic simulation are performed to analyze the trade-off between the accuracy and the computational time. The application of the method in real world is illustrated by an example from the logistic sector. Pack of instances: Click here to download
