Integrating Supply Chain and Production Chain: a Genesis in the Ethanol Industry

Abstract

ABSTRACT:Although frequently used interchangeably, the concepts of supply chain and production chain are considered in this study as two distinct and complementary theoretical frameworks for the conception of a data-mapping model titled SCMap -Supply Chain Map. The model's objective is to identify and assess real chains of companies and products. An application in the agribusiness sector, starting with a specific sugarcane processing plant and the biofuel ethanol is performed. The SCMap establishes a structured and integrated manner of linking products and companies, considering three different categories of relationships: (1) between companies -supply chain approach; (2) between products -production chain approach, and; (3) between companies and products -regarding commercial practices in the corporate environment. Grounded on Graph Theory and Social Network Analysis -SNA, the software UCINET and NetDraw application are used to draw the maps and quantitatively assess the centrality of each company and product relative to the whole chain.
