Abstract

The present study aims to establish the profile or MRP model adopted by small and medium enterprises (SME) in the metropolitan region of São Paulo, according to the MRP resources used. Small and medium enterprises represent an important segment of the market and to be competitive, they need efficient resources to manage their material requirements and acquisitions. The method used was a descriptive study, based on a questionnaire that was sent to a list of a small and medium size business located in metropolitan São Paulo city. It was not defined a specific segment, the prerequisite for participation in research was only that the companies were manufacturing in general and be a small or medium size, according to criteria adopted in this study. The contact with companies was conducted by e-mail and sometimes by telephone to obtain the answers quickly. The analysis concluded that the majority of respondent companies use most of the basic MRP resources, except the master production schedule and the lead time for each component. The analysis also indicated a trend in these companies: they quite do not understand the concept of MRP and have difficulties to implement these resources. Finally, this study proposes a typical MRP profile used by SME respondents.
