Avaliação de um sistema de aprovisionamento: O caso da Direcção dos Serviços Sociais da Universidade Eduardo Mondlane

Abstract

summary Organizations as an open system in the exercise of their activity relate to each other, acquiring or providing goods or services. To guarantee a continuous activity it is necessary that the necessary inputs are guaranteed in quantities and quality considered optimal, which can be produced internally or purchased. The need to avoid production stoppages and consequently the non-satisfaction of customers, which can bring great losses to the organization, leads to the creation of a stock; and this involves two interlinked activities, namely: purchasing and warehousing, which constitute the Procurement function. In this work, an evaluation of the Supply Management in the Directorate of Social Services (DSS) of the Eduardo Mondlanc University is carried out, on the one hand, to analyze the stock and purchase management processes, and on the other hand, to verify the applicability of some stock management models such as the Lote Econômico model and the ABC model. For the case of DSS, Wilson's model (which allows us to calculate the optimal order quantities and time) is difficult to apply because on the one hand it assumes assumptions that are not met in practice, and on the other hand there are many difficulties in obtaining the values ​​of costs related to stocks. Using the ABC method, of the forty (40) items involved in the purchase and storage process, eight (8), corresponding to 17%, consume approximately 70% of the total amount spent on purchases per month. These articles are considered strategic in the process; of supply management in which the economic lot model would be applied.
