Technical note on \((Q,r,L)\) inventory model with defective items. (English) Zbl 1201.90021

Summary: Under a reasonable assumption, we derive an analytical approach that verifies uniqueness of the optimal solution for stochastic inventory models with defective items. Our approach implies a robust method to find the optimal solution.
