The input module, the processing module and the output module are connected with the cloud storage module. The method comprises steps of determining production line available time according to real-time demands of orders, real-time demands of mixed products of scheduled orders in a former planned period and total demands of quasi-scheduled mixed products in a current planned period; distributing orders of different mixed products and delivery times to different parallel processing lines; and comprehensively considering setting time of products on each machine table to generate a mixed order-product production scheduling plan of each production line, maximizing the probability of completing products on each processing line in time in each plan period, and timely updating production programs of a numerical control machine tool. The objects of properly distributing different client orders to parallel production lines by batch according to differences in delivery times and items and further generating a production scheduling plan of each production line are achieved.

The invention discloses a sparse code division multiple access signal detection method based on a depth neural network. First, the relationship between users and resources is expressed as factor graph, Then the iterative transfer of information on the factor graph is transformed into the forward transfer of neural network, and then the signal detection error is estimated and the estimated value isused as the input data of the neural network, and then the gradient descent method is used to train the neural network to obtain better coefficients, and finally the trained network is used for SCMAsignal detection. Because of the use of neural network architecture, this method can be implemented on the corresponding AI chip. Compared with the traditional methods, this method can improve the performance and transfer the related computations to the high-speed parallel processing AI chip, which can effectively reduce the time delay caused by SCMA signal detection.
