Abstract:The two kinds of expected profits of newsvendor problem and its business expansion with discrete random requirement are clearly distinguished and explained based on the different meanings of accounting profit and economic profit and the importance of economic profit in economics and management The expected accounting profit model,expected economic profit model of newsvendor problem and its business expansion whose values number is limited,their extensions and the calculation expressions of the purchase quantities for expected profits maximization are obtained.The corresponding expected explicit cost and expected implicit cost are distinguished emphatically.It is pointed out that the operational research methods for solving such problems do not contradict the economic principles.
Keywords:random requirement  supply and demand  expected costs  expected profits
