Modelling Product Returns Taking Sales Modes into Account

This paper presents a model for estimating the number of returned products, taking sales mode differences into account. The model is constructed using actual copier collection data. The analysis of the data makes it clear that users who own and users who lease behave quite differently from each other, and that users who lease can be divided into two types: those who are aware of the lease period and those who behave as if they were not leasing but owning.
