Abstract: This paper discusses the effects of ramp-type of demand on an EOQ model for non-instantaneous Weibull deteriorating items under time-dependent partial backlogging. Here, we consider a retailer who purchases and sells a single product over an infinite time horizon faces a ramp-type of demand. Shortages are allowed and partially backlogged. The time to the deterioration of the item is distributed as Weibull. Total cost and the optimum number of replenishments are taken here as decision variables. The objective is to obtain the optimal replenishment policies that minimise the total cost. For demonstrating the model numerical samples are explained in the following sections.
