| Analytical method is one which is solved by using the deductive reasoning of mathematical theory. | Numerical method is the one which is solved by applying computational procedures. |
| Analytical method provide a direct solution and will result in exact solution if one exists. | Numerical method often require many iterations to get true solution. |
| Analytical method is exact and gives exact solution. E.g. value of 1/2 | Numerical method gives the approximate value or solution. E.g. PI=22/7 is approximate value. |
| Analytical methods are time consuming and sometimes impossible. | Mathematical methods are less time consuming and possible for most cases. |
| This model is best for designing calculations, suit for checking calculation with certain limitation. | This model is best for checking calculations, practically effective for designing calculation. |
| This model is not versatile & flexible . | This model is versatile and flexible. |
| Need much work to be developed, but only simple software for application. | Need expensive and complex software and hardware. |
