Embodiment Construction

[0037] The real-time dynamic rescheduling method of the process industry production scheduling system adopts a distributed computer management and control system, mainly including:

[0038]1. The system generally has a three-layer structure: enterprise resource management layer, manufacturing execution system layer, and on-site process control layer. Enterprise resource management mainly includes: sales subsystem, procurement subsystem, inventory subsystem, equipment subsystem, plan management subsystem and other business subsystems. use efficiently. The manufacturing execution system layer mainly includes: database server, real-time database server, data acquisition and service application server, application server, process monitoring computer, process scheduling computer, etc. It is the operation optimization layer of the production process to ensure how the production plan can be implemented smoothly on time. It mainly completes the transformation of the production plan i...

Abstract

The invention relates to a real time dynamic rescheduling method used for a process industry production scheduling system, aiming at solving the problems of present domestic process industry enterprises that production planning and dispatching have low efficiency, poor accuracy and real-time capability. The real time monitoring method of the invention includes the establishment of a scheduling-optimization math model and the working-out of a dispatching-optimization plan, the completion of the execution of production dispatching instructions and timely tracking calculation; a rolling optimization method includes the arrangement of dispatching time periods, the calculation of the state changes of various production data from present time to scheduling starting time, the generation of the data files of a target model and the establishment of the scheduling-optimization math model. The method of the invention is characterized by real-time, flexibility and promptness, etc. and can realize the integration of the control, the operation, the planning and the management of production-process and enterprise management to realize the balanced and high-effective production of enterprise logistics, production capability and source, thus enhancing the integral production efficiency of enterprises and reducing the cost of production and stock.

Description

technical field [0001] The invention belongs to the technical field of automation, and relates to a real-time dynamic rescheduling method of a process industry production scheduling system. Background technique [0002] Since the complex production system of the process industry has the characteristics of multiple varieties, large batches, short cycle, mixed flow production, and complex operation (including equipment failure, maintenance, material-intermediate product-product association, etc.), the production process contains a large number of complex resource constraints, Process constraints and energy constraints, all such planning and scheduling of production systems are very complex to formulate. [0003] At present, foreign production planning and scheduling software has been widely used in petrochemical, pharmaceutical, manufacturing and other process industries. Planning and production scheduling are inefficient, poor in accuracy, and poor in real-time performance. ...
