In this work, the characteristics of a dairy production process under diverse product uncertainties are investigated through a process simulation. The flexibility analysis method of Grossmann and his co-workers (Swaney and Grossmann, 1985) is applied through a process simulation tool, PRO/II. A new set of physical property models for diary products were developed and built into PRO/II system. Milk products viscosity and process system pressure drop were employed as the process characteristic parameters to determine a process operation window. The flexibility of the operation window vertexes was evaluated with a minimization of the process pasteurization and cooling temperatures through vertex enumeration method. The quantitative analysis of the dairy process established a framework in developing of different flexible units, such as integrated milk and milk-based product productions, multi-task process unit, etc.
