Abstract

The invention relates to an integrated optimization method for production planning and scheduling under uncertain requirements. At present, a production plan and scheduling problem solving mode is mainly a traditional optimization method, an optimization result is difficult to be an optimal solution, and the traditional optimization method cannot be realized technically, so that expected production targets cannot be realized, resource distribution cannot be issued, and the like. The method comprises the following steps: acquiring specific data of a production planning layer and a scheduling layer; respectively establishing a planning layer cost model and a scheduling layer cost model under the condition of uncertain demand according to the specific data; and utilizing an improved collaborative optimization method to optimize the plan and scheduling cost model under the condition of uncertain demand, and finally obtaining a production scheme with the lowest cost. Aiming at some problemsin production planning and scheduling optimization, the invention provides an optimization method with stronger global optimization capability, and the optimization method has the characteristics ofopenness, robustness, parallelism, global convergence, no special requirement on the mathematical form of the problem and the like.

Description

technical field

[0001] The invention belongs to the field of information and control technology, relates to automation technology, in particular to an integrated optimization method for production planning and scheduling under uncertain demand. Background technique

[0002] Production planning and scheduling has always been a decision-making problem that the chemical production industry pays special attention to. Production planning and scheduling is the use of modern and advanced methods and technologies, taking into account production constraints such as production process requirements and production resource conditions, optimizing the allocation of various manufacturing resources, formulating a production plan that meets the production requirements of the enterprise, and striving to meet the production requirements within the specified time. quantity to produce the desired product. The production plan is mainly aimed at factors such as the demand of a certain market and ...
