MICRO-COMPUTER MODELS FOR DYNAMICALLY DETERMINING ECONOMIC THRESHOLD
确定动态经济阈值的微计算机模型

Economic threshold should have dynamic characteristics.It may vary from years to years,even in same field.This paper develops a system models for determining economic threshold.They are consist of four models: 1.temperature m-odel,2.population dynamic models,3.control cost model,4.product yield model. Then economic threshold,at which marginal revenue equals marginal cost, will be determined by computer simulation.User can input different parameters according to different situations. The output of this compu...
