Conserving water by optimizing production schedules in the dyeing industry

摘要: Abstract Industrial dyeing processes generate a huge amount of wastewater, because the production lines have to be washed out each time when dye changes. We propose an algorithm for optimization schedule. It aims reduce and freshwater consumption by groups orders according color. Furthermore, we develop software based on genetic implement it in Chinese company. optimize schedules three months case company compare its output actual data. The results show that compared original manual schedules, optimized cut 10–15%, 20–30%, wastewater generation about 20%.
