One of the biggest challenges faced by companies is the production flow coordination along the supply chain (SC) in which they operate. Thus, practices have been developed both in academic and business environments that are used in supply chain management (SCM) since the late 1980's that allows such coordination. For manufacturing flow management process within the plant of a single company, the knowledge about usage of ordering systems can be found in current literature. Thus, the purpose of this thesis is to propose the use of the combined practices in SCM and pull ordering systems in SC. However, these ordering systems are seldom used for coordinating operations in SC, thus, can be assumed with a theoretical gap being exploited in terms of coordination mechanism of production flow in CS. The theoretical and empirical approach was used as methodological procedures. In terms of theory a bibliographic review was applied and was built a conceptual model. In terms empirical, was applied the conceptual model in a real case and was analyzed their consistence and result by simulation. A literature review was conducted to ensure the meaning of production flow coordination and SC and a detailed view of activities that theoretically ensures such coordination through the implementation of the Manufacturing Flow Management Process (MFMP). Based on this set of activities, a survey of the practices used in SCM and a conceptual analysis of contribution of with practice to the MFMP was performed. Meanwhile, another theoretical survey about pull ordering systems was performed with report analysis on the literature about the use of SC. Based on the elements that condone the use of each used practice in SCM and each pull ordering systems, a conceptual model of decision making for the combined use of both was designed. This model can help managers on decision making regarding the best practices and systems for each situation of pull systems. In order to validate the model a case study was performed in an automobile SC. The conceptual model was applied in two cases of the relationship with their suppliers and the impact on production flow coordination was analyzed through simulation. Based on the selected analysis variables there was an increase in the level of production flow management in all cases from the combined use of the practices compared to the previous case. To conclude it can be stated that through appropriate choices of combined use of practices used in SCM and pull ordering systems it is possible to achieve greater production flow coordination in SC.
