“…We note, however, that although a number of mathematical programming models have been proposed and successfully applied to real-world case studies (reporting the usefulness of safety stock strategies not just in enhancing service levels [113] but also in optimizing production, inventory quantities and backorders [108] , [112] ) optimal planned lead times might be preferable over safety stocks in certain situations [114] .…”

Highlights A review on operations research (OR) models and methods for safety stock determination is conducted. No work has yet systematized research focusing on the safety stock determination problem. Articles are classified and discussed regarding the modeling approach, industrial application, solution technique and main performance criteria used. Research opportunities, promising research directions and trends are identified.

“…Em muitos casos, os meios para garantir essa eficiência estão nos estoques, ou mais especificamente, na quantidade adequada de estoques. Keskin et al (2015) acrescentam ainda a necessidade da existência de estoques para cobrir desvios nos tempos de execução da produção, falhas na produção como quebras de equipamentos, por exemplo.…”

Aiming to balance market supply and financial goals, avoiding excessive costs with inventories, this dissertation proposes a model of stock management of asphalt for the enterprise in study. The developed management model aims to enhance the current management model, which is based on employees and collaborators experience, introducing measurements and academic grounds to the enterprise practices. This assessment aims to deliver the calculation of the safety stock levels on a quarterly basis instead of an annual basis due to the seasonality of the demand (the potential gains of quarterly calculation compared to the annul calculation will also be presented) and considering the uncertainties of production demand and lead time, the level of service being limited due to the capacity to stock, the definition of the stock control policies, the calculation of the replenishment point, and a comparison between current and theoretical stock costs, including as final product, an automatic spreadsheet for the exclusive use of the analyzed company, to update the variables and calculations when necessary.
