On the Connection between Optimal Stock Level and Distribution Structure in Multi-Echelon Storage System

In a single-echelon system, the optimal stock level has a square root rule-of-thumb with respect to the furcation degree. For a multi-echelon storage system, the connection between its optimal stock level and distribution structure (echelon number and furcation degree) is obtained by combination of theoretical analysis and numerical calculation, supplying a significant reference for the design of distribution structure.
