The invention discloses a method and system for dynamic optimization of raw material procurement specifications for a brightness enhancement film, comprising the following steps: obtaining finished product data; obtaining an initial feasible raw material size set; length-width direction mapping: performing length-width mapping on the initial feasible raw material set to obtain A complete set of feasible raw material sizes; screening to obtain a final set of feasible raw material sizes: screen the complete set of feasible raw material sizes, delete unreasonable raw material sizes, and obtain a final set of feasible raw material sizes; determine the size of the final feasible raw material size set; build a model Obtaining a small-scale subset; establishing a model of the small-scale subset; outputting the results; the present application aims to provide a method and system for dynamic optimization of raw material procurement specifications for brightness enhancement films, and an integer programming model is established through the final feasible raw material size set, Dynamic optimization of real-time order and inventory data to generate the most reasonable raw material specifications, raw material allocation plans, and raw material real-time procurement plans.
Description
technical field [0001] The invention relates to the field of procurement of raw materials for brightness enhancement films, in particular to a method and system for dynamically optimizing the procurement specifications of raw materials for brightness enhancement films. Background technique [0002] Brightness Enhancement Film BEF is a new type of high-performance optical film. Through the microprism condensing technology and the reflective polarized light recycling technology, the brightness of the LCD module can be increased to 160%-220% of the original, effectively solving the problem of mobile phone or The panel computer display has problems such as low utilization rate of light energy and short standby time. Therefore, the brightness enhancement film has become an indispensable and important component in the backlight module LCM of the display screen. [0003] In recent years, the screen size of terminal display equipment has increased year by year, which has led to a st...
