Embodiment Construction

[0032] A method for simulation verification of process industry simulation optimization scheduling, the specific steps are:

[0033] (1) Scheduling plan generation: According to product sales plan, raw material procurement plan, equipment maintenance plan, product (intermediate, raw material) inventory information and equipment production capacity, production resource occupation, consumption, production cost and other production constraint information, generate a target model The mathematical model of optimal scheduling is established based on the data files, and the optimal scheduling scheme is calculated according to the optimization goals set by the user (maximum production capacity, maximum profit, or satisfying sales orders) and the model solver.

[0034] (2) Predict possible production abnormalities through calculation: collect the current product sales plan, raw material procurement plan (including arrival status), inventory information, equipment maintenance plan, energ...

Abstract

The invention relates to a simulative validation method used for the simulative scheduling-optimization of process industry, belonging to the advanced manufacturing and automatization technical field and aiming at solving the problem that the actual scheduling problem is not solved despite certain development of present domestic production scheduling model, arithmetic and calculation capability. The method of the invention includes the following steps: the generation of a scheduling plan, the prediction of potential production abnormity by calculation, simulation by virtue of visible ESCPetri-Nets technique of a graph and the generation and the storage of process data. An actual result indicates that the adoption of the method of the invention can dramatically enhance the execution quality of the scheduling plan and enhance the utilization rate of raw material and manufacturing equipment with dramatic economical benefit.

Description

technical field [0001] The invention belongs to the technical field of advanced manufacturing and automation, and relates to a simulation verification method for virtual optimal scheduling in the process industry. Background technique [0002] At present, the production planning and scheduling level of the domestic process industry production process is still very backward, and the vast majority of enterprises are still in the manual stage. Their extensive planning and production scheduling are inefficient, poor in accuracy, and poor in real-time performance. Dynamic scheduling is extremely difficult, the overall efficiency of the production system is low, and resources are wasted seriously. Although some progress has been made in the production scheduling model, algorithm and computing performance in China, the actual scheduling problem is far from being solved. The emerging scheduling software lacks the simulation verification function of the rationality of the scheduling...
