Although terminology on such matters varies, the committee distinguishes composability from interoperability by Focusing on Challenging But Feasible Objectives, Not the requirement that it be readily possible to assemble com Grails ponents differently for different purposes. Interoperability, on the other hand, may be achieved only for a particular As discussed in Chapter 1, the committee recommends configuration, perhaps in an awkward one-time lash-up.

However, no one who has worked with higher-level Considerations modeling environments such as Mathematica, Analytica, There are, then, strong reasons for advocating separation iThink, or Extend would regard that approach as the only way, of conceptual model, implemented model, simulator, and or even necessarily the best way. Suppose, for example, one experimental context in model development and usage.

the solution is likely to be inof an integrated modeling environment should not be seen corporating tools to generate and export implementation-inas particularly troublesome, because if its approach to dependent characterizations of the conceptual model, method simulation (e.g., continuous rather than discrete-event) is a of simulation, and depiction of experimental context.
