急求一些仿真问题的解答
请教各位老师同学一些关于仿真的问题解答,哪位知道其中一些题目的解答劳烦相告,万分感谢! 不管是个人观点或是文献答案均可, 中英文均可,急等!!![*]Compare a logistic flow to a hydraulic flow. What are the physical similarities? [*]A. What are the differences respectively similarities if you model the hydraulic respectively the logistic flow as discrete respectively continuous generally?[*]What are the benefits respectively draw backs with discrete respectively continuous models for A.
A simulator connected to an on-line DCS (process computer) system?
B.
A production planning system
[*]You get the task from a company to develop a simulator for operator training for the. What steps should be taken? Which step is specially important to be careful with for a successful project (= happy customers)?[*]What are the most important things to consider if you should make a A.
Production planning system with a simulator as a basis?
B.
An engineering system for design of a new production plant?
[*]Discuss the differences between sequential and simultaneous solvers. [*]What are the main differences between Object oriented programming languages like Modellica and non-object oriented languages like ModL in Extend [*]What are the advantages respectively disadvantages with the simultaneous resp sequantial solvers for A.
On-line applications
B.
Simulation accuracy
[*]Discuss how differential equations can be formulated as difference equations. Examplify for the equation dc/dt = -D d2c/dx2 + v dc/dx – reaction rate *c
for how the concentration in a volume element is varying by time due to diffusion, convection flow and chemical reaction. Discuss what the different components in the equation means.
10. What is the difference between explicit algorithms and implicit algorithms
