[0002] In the plastics processing industry, there are many formulations that can meet customers' performance and quality requirements for plastic particles. However, the prices of raw materials in the formula fluctuate with market conditions, posing a severe challenge to the company's cost control strategy.

[0003] Faced with this challenge, many traditional companies have to rely on manual experience to adjust the formula manually, trying to find alternative materials or adjust the ratio when the cost of raw materials rises to maintain the competitiveness of their products. However, this method is not only inefficient, time-consuming and labor-intensive, but also easily affected by human factors, resulting in inaccurate formula adjustments and even deviations. Ultimately, not only does it fail to effectively reduce costs, but it may also increase scrap rates and overall production costs due to unstable factors in the production process.
