摘要: Abstract This paper presents the mixed inventory backorder and lost sales involving four variables; order quantity, lead time, safety factor rate. Optimal is obtained discretely. article assumes that an lot may contain some defective items number of random variable. Controllable negative exponential rate considered in existing model. In real market, as unsatisfied demands occur, longer length time is, smaller proportion would be. Considering this reason, dependent on through amount shortages. Negative crashing cost presented study, first demand follows a normal distribution then relax assumption about form function apply minimax free procedure to solve problem. Furthermore, num...
