Abstract
In case of one-product, one-period, normal distribution demand, emergency lateral transshipment instant arrival, four transshipment rules in the same echelon storage sites are discussed in this paper. They are one- time and full-sharing transshipment, one-time and partial-sharing transshipment, multiple-time and full-sharing transshipment, and multiple-time and partial-sharing transshipment. A total cost model is constituted on the factors of transshipment cost and shortage cost. Numerical experiments show that multiple-time transshipment can avoid the shortage risk of supply location; partial-sharing transshipment can drive down the shortage risk of supply location; decision of transshipment rule mostly depends on unit cost of transshipment, unit cost of shortage, and distance between the storage sites.
