Problem Farm_Planning — Constraint detection

A farmer wishes to plan production on his 200 acre farm over the next five years . At present , he has a herd of 120 cows . This is made up of 20 heifers and 100 milk-producing cows . Each heifer needs 2/3 acre to support it and each dairy cow 1 acre . A dairy cow produces an average of 1.1 calves per year . Half of these calves will be bullocks , which are sold almost immediately for an average of pounds 30 each . The remaining heifers can be either sold almost immediately for pounds 40 or reared to become milk-producing cows at two years old . It is intended that all dairy cows be sold at 12 years old for an average of pounds 120 each , although there will probably be an annual loss of 5 % per year among heifers and 2 % among dairy cows . At present , there are 10 cows each aged from newborn to 11 years old . The decision of how many heifers to sell in the current year has already been taken and implemented . The milk from a cow yields an annual revenue of pounds 370 . A maximum of 130 cows can be housed at the present time ; to provide accommodation for each cow beyond this number will entail a capital outlay of pounds 200 per cow . Each milk-producing cow requires 0.6 tons of grain and 0.7 tons of sugar beet per year . Grain and sugar beet can both be grown on the farm . Each acre yields 1.5 tons of sugar beet . Only 80 acres are suitable for growing grain ; they can be divided into four groups whose yields are given in a table . Grain can be bought for pounds 90 per ton and sold for pounds 75 per ton . Sugar beet can be bought for pounds 70 per ton and sold for pounds 58 per ton . The labour requirements are given in a table . Other costs are given in a table . Labour costs for the farm are at present pounds 4000 per year and provide 5500 h labour . Any labour needed above this will cost pounds 1.20 per hour . How should the farmer operate over the next five years to maximise profit ? Any capital expenditure would be financed by a 10-year loan at 15 % annual interest . The interest and capital repayment would be paid in 10 equally sized yearly instalments . In no year can the cash flow be negative . Finally , the farmer would neither wish to reduce the total number of dairy cows at the end of the five-year period by more than 50 % nor wish to increase the number by more than 75 % .
