### Validation and verification of mathematical models

Within the subject of simulation I have found some literature on validation and verification (e.g. Sargent's paper). My question is, what techniques do you use to validate and verify your mathematical ...

### OR-backed serious games

A "serious game" is a game (usually a simulation) designed for a primary purpose other than pure entertainment. Games like the beer game or the fresh connection can be considered serious games serving ...

### Good distribution assumptions for customer demand in a supply chain

Why do we normally assume normal distribution/Poisson distribution for customer demand in a supply chain? Are there other good distribution assumptions?

### Good textbook for queueing theory and performance modeling

Can someone recommend a good self-study textbook for queueing theory and performance modeling? My interest is in applying this to understanding the behavior of some real-world server networks, ...

### Simulation optimisation: Monte carlo simulation, regression, optimise within regression model?

Can you help me identify if this technique has a standard name to help me explore the literature? Suppose I have a black-box stochastic simulation parameterised by $X=[x_1,...,x_p]$ with some single ...

### How to fit a Beta distribution to three estimates from an “expert”?

I'm modeling a process time, $X$, for a simulation study and have an "expert" estimate of the minimum, $\hat a$, the most likely (mode), $\hat m$, and the maximum, $\hat b$. I'd prefer to avoid the ...

### Alternatives for real-world data collection in simulation courses for Fall 2020

I teach a discrete-event system simulation course in Fall 2020. As with most DES simulation courses, students have term projects that involve gathering real-world data and building stochastic input ...

### In Linear programming, how to determine if shadow price does not change linearly?

As the title says, in linear programming, is there a way to determine that the shadow price does not change linearly for a resource? I understand one way is to simulate but is there a way to tell ...

### Is this the same as Agent Based DES or something different?

DES (Discrete Event Simulation) is a simulation paradigm which can be applied to some OR problems, if combined with SO (Simulation Optimisation). AB-DES (Agent-Based DES) is an adaptation where the ...
