Design of Experiments for Simulation Modeling
Simulation models often have many input factors and determining which ones are really important can be quite difficult. In this SimCast, Dr. Averill M. Law, President of Averill M. Law & Associates provides a brief introduction to design of experiments for simulation modeling.
The Critical Importance of Simulation Input Modeling
An important, but often neglected, part of any sound simulation study is that of modeling each source of system randomness by an appropriate probability distribution. In this Simulation Master Class, Dr. Averill M. Law of Averill M. Law & Associates first gives examples of data sets from real-world simulation studies, followed by a discussion of two critical pitfalls in simulation input modeling. The two major methods for modeling a source of randomness when corresponding data are available are delineated, namely, fitting a theoretical probability distribution to the data and the use of an empirical distribution. Finally, there is a discussion of how to model a source of system randomness when no data exists.

Queue Modeling in Excel
This lesson introduces the queue model template. It first looks at the M/M/s model. We then explore an example scenario where we need to find the optimal number of servers for a company. In doing so, we develop a one-way data table to analyze cost. We then introduce the M/D/1 model. Using the M/D/1 model we explore a business’s recapitalization decision. In analyzing this decision, we utilize Excel’s built in what-if analysis and construct a two-way data table. https://ericjjesse.wordpress.com/course-introduction/queues/

Little's Law Simple Form
Little's Law captures the relation between WIP, Throughput Time (or Lead Time), and Production Rate. Application leads towards lean production, muda elimination, and smooth material flow . Dr S. Gondhalekar with Mrudula Pardeshi and Pranali Pisat facilitate understanding of Little's law in simplified form, and how WIP reduction can be done by lead time reduction or throughput time reduction with a pleasantly visual representation using toy cars.

Module 5-Modelling & Simulation: Thermodynamic and FEM Analysis in SPS
Speaker: Dr. Zhe Zhao (University of Stockholm) Abstract:Spark Plasma Sintering (SPS) has been an attractive sintering technique for preparing nanostructured ceramics and composites for more than 10 years, but there is still no clear image about the sintering mechanisms behind the enhanced densification. Here we will use traditional sintering and creep deformation kinetic method to analysis the densification process in SPS in order to shade light on the potential mechanisms which make SPS different from the other normal pressure-assisted sintering techniques. As another potential technical obstacle to SPS applications for mass-production, the intrinsic temperature and stress profi les are also analyzed by FEM. Both transient and equilibrium state are considered. The knowledge from this lecture can be used as the general guideline for SPS experiments in Labs or industries.

Sugarcane bagasse pneumatic separation with different shapes using Ganser drag law
This simulation, performed by researchers from the University of Campinas, shows the 2-way coupling CFD-DEM (ANSYS Fluent and Rocky DEM) technique as a powerful tool to enhance the sugarcane bagasse pneumatic separation process understanding. Different particle shapes for the bagasse are used and the air flow rate is varied in order to evaluate different operational conditions. The use of Ganser drag law takes into account the particle shape and alignment with the flow and allows the correct prediction of the separation efficiency.

Discrete Event Simulation Using ExtendSim: Output Analysis
Problems encountered when analyzing simulation output that are modeled with queuing processes occur frequently. In this SimCast, Dr. Jeffrey S. Strickland, PhD, CMSP, ASEP, President of Simulation Educators explains two of the problems that typically occur: 1. The Initial Transient Period 2. Autocorrelated Observations Simulations take time to warm up to their steady state behavior, unless something is known about it when modeling a system. This warm up period or initial transient period must be accounted for in experimental design. Waiting times are not independent--they are autocorrelated--and these must also be dealt with in experimental design. It is easy to pick these problems apart by running a simple M/M/1 queue model.

The Hardy-Weinberg Principle:  Watch your Ps and Qs
The Hardy-Weinberg Principle states that allele and genotype frequencies in populations remain stable over time, given certain assumptions. What assumptions? What does the principle mean? And how do you SOLVE those Hardy-Weinberg PROBLEMS? Everything shall be revealed in this video - with some penguins of course. They make everything go down easier.

Traits aren't blended! Cambridge opens a department of Genetics So What's it All About? It's about frequencies When talking about population genetics, we are interested in the prevalence of a particular allele or genotype in a population The Hardy-Weinberg Principle States: Frequencies of alleles and genotypes in a population will remain constant over time in the absence of other evolutionary influences Assumptions Organisms are diploid Generations are non-overlapping Population must be large No immigration or emigration No mutation in the gene of interest No natural selection occurs (individuals reproduce at equal rates) Mating is random Alleles and Allele Frequency Penguin Prof Helpful Hints The Sum of All Possible Outcomes MUST Equal 1 p+q = 1 ALLELE FREQUENCY 2 Alleles = Genotype p2 + 2pq + p2 = 1 What if There are Three Alleles? (p, q and r) Sample Problem In a population of 1,000 penguins, 12 have blue feet. Find the frequency of the blue allele, the yellow allele and the frequencies of the three possible genotypes in this population. Solving Hardy-Weinberg Problems Assign the alleles Frequency of the dominant allele is 'p' Frequency of the recessive allele is 'q' Calculate q by taking the square root of the number of homozygous recessive individuals Calculate p (the allele frequencies must equal 1, so p = 1 − q) Use p and q to calculate the other genotype frequencies: frequency of homozygous dominant individuals = p2 frequency of heterozygous individuals = 2pq frequency of homozygous recessives = q2 This may help: Hardy-Weinberg Punnett Square Try Another One... In a population of 130,000 magical mice, green fur is dominant over orange. If there are 300 orange mice in a population of 130,000, find the following (assume population is in Hardy-Weinberg equilibrium): 1. Frequency of dominant (green) allele 2. Frequency of recessive (orange) allele 3. Frequency of each genotype
