The 13 Lucky steps to writing a great model!!
The 13 Lucky steps to writing a great model!!<br/><br/>1. Select problem<br/>2. Define problem<br/>a. Define the variables<br/>b. What we are trying to optimize<br/>c. Understand every possible thing that can influence problems<br/>3. Make problem manageable (make assumptions)<br/>4. Criteria / constraints<br/>5. Possible models / approaches (brainstorming)<br/>6. Debate / selecting a model<br/><br/>INTERMISSION<br/><br/>7. Reorganize:<br/>a. Satisfies constraints<br/>b. Feasible?<br/>c. Everything is justified<br/>d. Simplest possible?<br/>e. Clear plan of action on proceeding<br/>8. Model architecture<br/>9. Build base case model (prototype)<br/>a. Picking likely parameters<br/>b. Most likely build simulation<br/>c. Run simulation on data to get results<br/>10. Sensitivity testing of prototype & optimize parameters<br/>11. Formal write-up of prototype<br/>12. Evaluate prototype<br/>a. Mistakes made, faulty assumptions, missed assumptions<br/>b. Expansion of model<br/>c. Revise (?) if necessary<br/>13. Iterate<br/><br/><br/>--------<br/>在国外一大学网站上看到的，还不错<br/>[此贴子已经被作者于2008-2-11 19:07:25编辑过] 自己sf~ dingyixiaba bu rongyi a {:3_55:}
