Abstract:

We first analyze the actual operation of a cold chain logistics enterprise in shaanxi province, and use the unified modeling language (UML) with a userfriendly interface, which can describe the system effectively, and the polychromatic sets (PS) theory with a rigorous mathematical foundation, to build the operation process model of a cold chain logistics warehouse. Then we analyze the model structure and time accessibility, which can ensure the rationality of the process model. We also propose some suggestions on the optimization of the workflow, and build up a new model for the input/output process of the coldchain logistics warehouse. We compare the expected operation time of the model before and after optimization, and the results show the effectiveness of the optimized model.
