Resumo
O mercado de adquirência vem sofrendo diversas mudanças nos últimos anos com alterações de regulamentações e aumento da competitividade. Neste cenário o supply chain management (SCM) tem ganhado cada vez mais relevância no setor, levando as empresas a melhorarem o nível de serviço de atendimento ao cliente e a manter os custos sob controle. Entretanto, foi identificado que o SCM é um campo pouco explorado no mercado de adquirência, sendo então este trabalho uma oportunidade de contribuir para o meio acadêmico. Foi observada também a oportunidade de construir um modelo de estoque considerando o transporte como custo variável, diferentemente da maior parte dos modelos encontrados nesta pesquisa da literatura. O objetivo deste estudo foi desenvolver um modelo de alocação de estoque para cadeia de SIMcards em uma empresa brasileira do ramo de adquirência, mantendo o nível de serviço acordado com o cliente. Foram calculados os custos de estoque e de transporte para diferentes ciclos de abastecimento para todas as combinações de bases e operadoras dos SIMcards, de modo a obter a configuração de menor custo total da cadeia. Os resultados mostraram que não se pode considerar os custos de forma individual e considerando ambos os custos, transportes e estoque, tem-se oportunidade de aumento de eficiência na operação estudada. Foi verificado também que as diferenças nas variáveis entre cada base, especialmente a demanda, influenciam na definição do ciclo de abastecimento com o menor custo, confirmando a importância de se realizar avaliação caso a caso.

In this scenario, supply chain management (SCM) has been gaining greater relevance in the sector, leading companies to improve the level of customer service and keep costs under control. However, it was identified that SCM is a less explored field in the acquirer market, so this work is an opportunity to contribute to the academic research. It was observed the opportunity to build an inventory model considering transportation as a variable cost, unlike most models found in this literature search. The objective of the study was to develop an inventory allocation model for the SIMcard chain in a brazilian company in the acquiring sector, keeping the service level agreed with the customer. Inventory and transport costs were calculated for different supply cycles for all SIMcards operators and transportation hubs, in order to obtain the lowest total cost configuration in the supply chain. The results show that the costs cannot be considered individually and considering both costs, transport and inventory, there is an opportunity to increase efficiency in the studied operation of this work. It was also verified that the differences in the variables between each transportation hubs, especially the demand, influence the definition of the supply cycle with the lowest cost, confirming the importance of carrying out a case by case assessment.
