Dynamic optimization method and system for procurement specifications of brightness enhancement film (BEF) raw materials

A dynamic optimization method for procurement specifications of brightness enhancement film (BEF) raw materials, comprising:

• (a) obtaining finished product data according to order information within a preset period;
• (b) according to the finished product data, generating an optimal raw material size corresponding to individual finished products to obtain an initial feasible raw material size set;
• (c) mapping the initial feasible raw material size set in length and width directions to obtain a complete feasible raw material size set;
• (d) removing an unreasonable raw material size from the complete feasible raw material size set to obtain a final feasible raw material size set;
• and
• (e) judging whether a scale of the final feasible raw material size set is larger than a preset threshold:
• (e1) if not, building an integer programming model based on the final feasible raw material size set;
• solving the integer programming model, and outputting results;
• and
• (e2) if yes, performing batch processing on the final feasible raw material size set to obtain multiple subsets;
• building an integer programming model for each of the subsets;
• and solving the integer programming model, and outputting results.
