Model Persediaan dengan Power Demand dan Partial Backlogging di Bawah Harga dan Permintaan Bergantung Waktu

Abstract

This paper discusses an inventory model with power demand whose demand is a bivariate function of price and time which is the product of two power functions, one depending on the selling price and the other on the time elapsed for the last inventory replenishment. It is assumed that only a fraction of demand is backlogged during the shortage and the remainder is considered as lost sales. This inventory model is an EOQ model that aims to determine the optimal price, order quantity and replenishment cycle that maximizes the total inventory profit per unit time. Some numerical examples are given to demonstrate the use of this method.
