MODELLING W/ GENERAL PURPOSE LANGUAGES
Advantages:
– Little or no additional software cost
– Universally available (portable)
– No additional training (Everybody knows…(language X) ! )
Disadvantages:
– Every model starts from scratch
– Very little reusable code
– Long development cycle for each model
– Difficult verification phase
GEN. PURPOSE LANGUAGES USED FOR SIMULATION
FORTRAN
– Probably more models than any other language.
PASCAL
– Not as universal as FORTRAN
MODULA
– Many improvements over PASCAL
C, C++
– Object-oriented programming language
MODELLING W/ GENERAL SIMULATION LANGUAGES
Advantages:
– Standardized features often needed in modeling
– Shorter development cycle for each model
– Much assistance in model verification
– Very readable code
Disadvantages:
– Higher software cost (up-front)
– Additional training required
– Limited portability
