RESUMO:

The bullwhip effect (BE) is a phenomenon present in the supply chains characterized by the variability of the demand, causing an amplification upstream of the quantities handled, implying in the formation of excess stocks and, consequently, in the increase of logistic costs. There is consensus in previous studies regarding the definition and causes of BE. However, the proposed models for the quantification and development of solutions for BE mitigation still constitute a broad field of research, given the gaps identified in the literature, such as analyzes that contemplate the composition of Marketing, transport capacity, seasonality and costs. Thus, the objective of this work is to develop a support model for the management of supply chains to evaluate the impact that Marketing actions, carried out in defined periods of time to stimulate the commercialization of the products, exercise in the BE. Supply rationing, lead time and minimum inventory, which are agents that cause variability in demand, besides the differentiation of items according to the ABC classification, were considered in the model structuring. The study, then, can be classified as exploratory and descriptive. Regarding the approach, the research assumes a qualitative and quantitative nature, of an applied nature, through the collection of data from a company that operates in the retail of civil construction, to assist in the identification of reference values to validate the proposed model. In order to make the study feasible, due to the complexity resulting from the relationship between the variables involved, it was used as a tool the simulation, from the System Dynamics (SD), because it is a controlled environment, allowing the replication with ease of the experiments, enabling the construction of scenarios and favoring analyzes, the results of which help the decision-making process. The simulations carried out, supported by bibliographical references, allowed us to confirm that the redemption of the supply balance in the purchase order composition significantly reduces the BE; the presence of more distribution channels elevates the BE; the establishment of minimum and maximum points for the stock, in accordance with the ABC classification, allows to reduce the BE, given the representativeness of the items; the evaluation of stock levels and supply balances act as regulatory elements, which may lead to the reduction of the BE; and the practice of promotion and supply rationing calendars focus on increasing the BE.
