recently, abad (2003) studied the princing and lot-sizing problem for a perishable good under finite producation, exponential decay, partial backordering and lost sale. in this article, we extend his model by adding not only the backlogging cost but also the cost of lost goodwill. we then analytical compare the total profits between abad's (2003) model (in which the cycle starts with an instant production to meet the unsatisfied demands.) and goyal and giri's (2003) model (in which the cycle begins with a period of shortages, then starts production until accumulated inventory reaches certain level, and finally stops production and uses up inventory). in addition, we show that there is no dominant model. furthermore, we provide certain conditions under which one is more profitable than the other. finally, we give several numerical examples to illustrate the results.
