Feed A consumes less raw materials, takes a little longer and has low profit. The production time of feed B is short, the consumption of raw materials is large and the profit is high; It takes a long time to produce C feed, with average profit and many raw materials.

According to the current stock of raw materials, with the principle of maximizing the conversion of raw materials into feed and the purpose of maximizing profits, there are the following schemes:

1, 4A+2C: raw material A consumes 8T, raw material B consumes 10T, and the profit is 200,000, but the working time is 20 hours, far exceeding the stipulated time 16 hours. This scheme has the advantages of long running time, high power consumption, high labor intensity, high raw material consumption, high cost, low efficiency and high profit.

2. 1A+2B+ 1C: raw material consumption of Party A is 8T, raw material consumption of Party B is 7T, working time is1/hour, and profit is 1.7 million yuan. The scheme has the advantages of short working time, low energy consumption, less raw material consumption, low relative cost and high efficiency.
