* p, l& O0 n1 c4 t8 @There's a common misconception that performing a simulation study involves a sequence of steps (e.g., project definition, model formulation, verification, validation, analysis). To the contrary, all elements of a simulation project should be performed repeatedly throughout the effort, 6 o3 u% x$ l4 f+ O+ V

Intermediate milestones, spaced no more than about two weeks apart in a medium to large project, should include specific goals for the model, animation, data, and analysis. By the time you reach the last 25% of your time on the project, you should have addressed the basic analysis issues of run length, warm-up time, etc. and should already have performed preliminary analysis on the model for a number of different scenarios. |
