|
|
|
| Abstract: |
| Based on the study of three indexes including product sale a mo unt, profit margin and market share, a fuzzy identification model on product lif e cycle is created. It is tested with an example, the result shows that this mod el is an effectively method by which a product life cycle can be identified quan titatively. |
| Key words: product life cycle,fuzzy set,fuzzy identification |
