Introduction In the future warehouse material transportation will be shown as high speed, high mobility and high precision, and will rely more on material distribution.
Warehouse transportation is a crucial part of material distribution.Whether the transportation of materials is quick or not, it will directly affect the supply efficiency of materials.
It is assumed that a warehouse is going to delivery material to a number of customer points.
Each vehicle's maximum load is 20 tons and it is required to deliver warehouse material to 25 customer point.

La0.7Sr0.15Ca0.15Co1-yFeyO3-δ(LSCCF)powders with 0.2y0.5 for the applications as the cathode materials in intermediate temperature solid oxide fuel cell(ITSOFC) were synthesized by glycine-nitrates-process(GNP) using metal-nitrates and glycine as the raw materials.
Therefore, the LSCF has become the recent focus of ITSOFC cathode materials research since it can reduce the operation temperature of SOFC using LSCF as cathode materials [1-5].
For researched the performances and synthesis method of cathode materials deeply, La0.7Sr0.15Ca0.15Co1-yFeyO3- cathode materials were prepared by glycine-nitrates-process (GNP), and the influences of B site doped on performances were researched in this paper.
