Abstract

In order to manage the complicated waste paper collection and wholesale system, the activities of companies in this field were analyzed and modeled using Quantification Theory III, which converts qualitative information into quantitative parameters.<BR>Characteristics of each company were categorized based on a questionnaire that focused on waste paper collection activities. A work-flow model of the collection system was then developed.<BR>Companies were grouped into three kinds of collectors and wholesalers.<BR>It was found that the different systems for material flow of waste papers are different depending on their sources.
