| Summary: | Many researchers have developed various economic ordering quantity models by assuming an infinite time horizon
and constant demand rate. However due to rapid technological advancement, shorter product life cycle and severe
competition, those assumptions are no longer realistic. In this paper, we complement that shortcoming by considering
an inventory model that satisfies a continuous time-varying demand rate for a finite time horizon when trade credit
period and unit cash discount are allowed. The time horizon consists of n different cycles with equal or different cycles
length. The trade credit period was assumed to be proportional to the cycle length. We developed mathematical models
and presented a numerical example to support the effectiveness of these models. |
