Tandem stereoscopic warehouse is a special form of stereoscopic warehouse, which is convenient flexible arrangement and suitable for many fields limited condition in the warehouse. Tandem stereoscopic warehouse deals with many special theoretical problems compared to the normal warehouse. A new method of weight endowment was put forward and additional target suitable for actual needs was provide to solve the path generation problems which is the most central and most complex problem in tandem storage spaces. An evolutionary algorithm based on immune genetic was proposed to solve the above model. Numerical simulations showed that the method can effectively convergence; by comparison with the example of a simple genetic algorithm, the algorithm to achieve acceptable suboptimal solution speed is fast. The purpose was to provide reference for theoretical research and engineering application.
