Here are some key differences between them: “What-if” analysis: Simulation is better suited to observing the performance of the simulated system by tweaking the initial conditions (that is, the values of the input variables). Optimization is used more often to determine an optimal system design.

A process evaluation describes a program's services, activities, policies, and procedures. ...

When conducting cost-benefit analysis on a project or proposal, you'll get a more accurate result by converting all future costs and benefits to their present values. Subtracting the present values of all costs from the present values of all benefits gives you the net present value of the project, or NPV.
