While Network optimization can be very detailed with sophisticated mathematics, sometimes working to get 100% precision and accuracy does not have a financial payoff due to:
1- the effort to move from 80% accuracy to 100%accuracy always decreases
2-the segment of the supply chain where you are Chasing the details, does not have a significant impact in the overall model
3-all good modeling software always have a tool to estimate the values you need for the model
4-there is always a shortcut Available to save time and model the data with selected Value
5- you can never get the model to 100% accuracy
