| Abstract | In this paper, an extension and an application to the green procurement model based on Coloured Petri Nets is presented. The large number of services and providers for services that can exist in a company means a problem when it comes to managing purchases and much more if the purchases. If the purchases have a benefit such as the sustainability of the companies processes that provide the service, the problem is even greater. This paper aims to develop an extension for this proposed model using the petri nets tools thanks to its ease of modeling complex systems. Likewise, a new algorithm applied to the place of selection of suppliers and a methodical mathematical formalization was developed. Finally, two examples are implemented. The first example allows understanding and applying the model in a simple way. In the second example or study case, be proposed an application in a services company. This example describes the step by step of the evolution of the model and the results obtained by each stage. The application of the final example shows the qualitative advantages of the developed model and the need to apply some technique of quantitative analysis of easy integration to the model that will be defining in a future research.
