1. A system for producing display panels based on a nonlinear program model, comprising: a distributed storage device, an analysis device, and a production line, wherein:
the distributed storage device is configured to store production data generated by a factory device;
the analysis device comprises one or more processors configured to perform operations comprising:
acquiring production record information within a first historical time period from the production data;
constructing a nonlinear program model based on the production record information; and
solving the nonlinear program model to obtain multiple first feasible solutions;
wherein the nonlinear program model comprises a constraint condition that satisfies process requirements and an objective function indicating pressure equilibrium across the same device set,
each of the first feasible solutions is configured to indicate a production program, comprising a quantity of at least one product to be put into production at multiple time intervals within a first preset time period, and
the production line is configured to produce the display panels according to the production program,
wherein after the step of solving the nonlinear program model to obtain multiple first feasible solutions, the operations further comprise:
acquiring production program information within a second historical time period from the production data, and
screening the first feasible solutions based on the production program information to obtain a second feasible solution, wherein
the second feasible solution is configured to indicate a production program,
wherein the step of screening the first feasible solutions based on the production program information to obtain the second feasible solution comprises at least one of the following cases:
a total number of production times of the same product within a first preset time period in the second feasible solution does not exceed a maximum number of production times of the product within the first preset time period in the production program information; and
an input time interval between adjacent lots of the same product in the second feasible solution is not less than a minimum input time interval between adjacent lots of the product in the production program information.
