I urgently need your help. Currently I’m conducting a research in regards of the revenue calculation and the dynamics within revenue calculation for my masters. I thought of revenue/profit margin as of a dynamical system – Lotka Volterra differential equations. I thought of a contribution margin calculation as within this simple formula:
In consequence my idea was the following, but I receive an error:
- Can anyone help me?
- Do you think it’s a bad idea to use Lotka Volterra equations for this nonlinear purpose of Sales/Cost/Margin Simulation?
- How would you model it and why? Am I missing equations or does the simple system already fit the requirements?
- How do I generate a valid plot out of these results (Phase Portrait etc.)?
