A SYSTEMATICALLY SIMULATED MODEL OF DEVELOPING ANIMAL HUSBANDRY FOR PLANNING THE DAIRY HUSBANDRY IN HEILONGJIANG PROVINCE
畜群发展系统仿真模型的建立——黑龙江省奶牛业发展方案的研究

Based on the Lewis-Leslie's model and the principles of the systematic dynamics a piecewise matrix model of developing animal husbandry was proposed in this paper. The model could be used for planning the animal herd construction and acquiring the information about input and output in animal production. The systematically simulated model and throe programs for developing dairy husbandry in Heilong-jiang Provice were designed and evaluated from the point of view of the ecologic-economics model theory.
