Modeling and Simulation Use for Terminal Sizing and Decision Support Available to Purchase

Modeling and simulation techniques were used for sizing and management of tank farm facilities. Probabilistic models representing interfaces (market, supply, production, laboratory, etc.) were represented in the model. The technique allows simulation of the logistic costs and service level in different scenarios, subsidizing technical and managerial decisions leading to optimization of inventories. Major advantages are: 1 – once it is created, a model can be used several times to assess the proposed projects and policies; 2 – the analysis methodology used by simulation enables the assessment of a proposed system, even if the entry data are still under form of schemes or drafts; 3 – simulation is generally easier to be applied than analytical methods; A partnership was created among several of Petrobras’ managers for the development of the so-called “Integral and Integrated Model of Transfer and Storage”. Examples of application of such model to some terminals and the relevant results obtained will be shown.
