Problems solved by technology

However, especially systems with multiple processing schemes and multiple product characteristics in chemical processing have not appeared. At present, many enterprises rely on experienced experts to spend a lot of time arranging the processing schemes of each device, and manual arrangements often have insufficient consideration. , sometimes in order to quickly come up with a solution, some benefit concessions may be made

Embodiment

[0024] This embodiment adopts two sets of polyethylene devices U1 and U2. Device U1 has 5 processing schemes, and the corresponding products are P1, P2, P3, P4, P5 respectively; device U2 has 6 processing schemes, and the corresponding products are P4 respectively. , P5, P6, P7, P8, P9, both devices have the processing plan of the same product P4 and P5, the same product will finally enter the same product storage container, and finally leave the factory; wherein the raw materials F1 and F2 are respectively propylene And ethylene, devices U1 and U2 are 1# polypropylene and 2# polypropylene devices respectively, and products P1, P2, P3, P4, P5, P6, P7, P8, P9 are: K9930, K7726H, T4401, N-Z30S , PPH-MM20-S, HT9025NX, PPR-F08-S, F300M, PPH-T03-P2, the process of adopting the technical solution of the present invention to switch the processing scheme is as follows:

[0025] U1 device:

[0026] (1) From the 31st of last month to the 3rd of this month, produce P3 products with a dail...

Abstract

The invention belongs to the technical field of chemical industry, and relates to a method for improving the switching efficiency of multi-device and multi-product processing schemes. According to the raw material arrival plan and product delivery requirements, combined with the constraints of production conditions, optimal arrangements are made to obtain reasonable processing in a short time. According to related results such as plan switching arrangements and product output and inventory changes, the method of the present invention can obtain the optimal processing plan switching strategy, reduce production costs, and improve enterprise benefits; the method is simple, easy to operate, scientific in principle, and can be processed in the shortest Arrange the processing plan reasonably within the time limit to maximize the production efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of chemical industry and relates to a method for improving the switching efficiency of multi-device and multi-product processing schemes. Background technique: [0002] In petroleum refining production, plan optimization products are widely used and have achieved remarkable economic benefits. The production of chemical products is often produced under such a mode. The main raw materials input, under different conditions, produce products of different grades, which are referred to as different processing schemes below, such as the production of polypropylene. Propylene is polymerized in different Different grades of polypropylene products are produced under different time and different additives. The market demand for products of various grades changes greatly, and factors such as weather, raw material prices, and surrounding markets may have an impact on product prices. At the same time, the processing cos...
