[SYSTEM-N] Paper factory production control system
Dynamic and static system
The model describing the action of the system about the time of a simulation model is called dynamic model.
On the other hand, the model describing the action of the system at a certain time is called static model.
For example, the model which only shows the profits at the end of a fiscal year is static. The model showing an action is dynamic as a function of time to let one year pass to it. The difference is the same as a photograph and a movie.
Many static models are performed using a spreadsheet or financial software. simulation is further classified into a conclusion model and a non-ending model.
In a conclusion system, when a certain important matter arises, a simulation ends. For example, in a bank, when business is completed, a simulation is ended. When there is a certain occurrence, supposing it ends automatically, it will be thought that the system is a conclusion.
In a non-ending system, such an important occurrence does not happen but a system is continued infinitely. Here, a production plan is real time dynamically and is treated as a non-ending model.

Sound simulation System
The sound place simulation system has the function which can carry out the simulation of the sound of an actual hall, if an exact drawing is put in. Since the building cannot be remade after having built it, the check of sound is required for it in the stage of a drawing.
A hall should have the possibility of various good designs in the form of land, and the form of a building. If a best solution is desired really scientifically, various forms should be tried and the best should be chosen in it. Then, this simulation system is needed.
