Unique part number reduction across the enterprise can provide numerous benefits. While it’s desirable to reduce the part count in a given product, what we are focusing on in this article is reducing the unique part numbers in the ERP system across all product lines. For our purposes here, the terms part number or part …
An important part of managing a project is project risk management. Not identifying and managing risks can take down a project in short order. Therefore, risk management should be done for all but the most trivial projects. Even if we are willing to accept a given risk level in order to take advantage of an …
As part of risk management, a project risk analysis is performed to assess the impact of risks and the probability of the risk occurrence. In this article we will look at the differences between qualitative and quantitative project risk analysis. To see how project risk analysis fits within risk management, please refer to this article. …
Qualitative vs. Quantitative Project Risk Analysis – What’s the Difference? Read More »
Risks are everywhere. It’s a wonder that anyone leaves their house each morning to venture into the world, or to venture into projects and investments. In this article we will look at the meaning of risk. There are many definitions of risk depending on the context, or industry. Also, risk is frequently used as a …
Congestion at a car wash during peak hours can be a source of customer frustration as well as lost revenue. We will perform a car wash queuing analysis of a proposed in-bay automatic car wash that is part of a convenience store. An in-bay automatic car wash consists of a machine that passes back and …
In this article we will perform a Dewar flask design optimization using Simulation Master’s optimizer. In a previous article we analyzed a Dewar flask’s design that was used to shield down hole electronics from high temperature oil & gas well bores. In that article we had a fixed design, and treated emissivity of the vacuum chamber …
A Dewar flask is used in the oil & gas industry to protect electronics from high temperatures experienced down hole. As temperatures increase, reliability of electronic components decrease and ultimately fail. We will analyze a Dewar flask design using Monte Carlo simulation of time down hole before an internal flask temperature of 435 Kelvin is …

Six Sigma and big data has taken metrics to a new level. There they are measuring progress, pointing the way to improvement, and determining how big the bonus will be this year. Knowing where you’ve been and where you’re going is a good thing, so what’s wrong with using metrics as much as possible? Beware …
Monte Carlo integration can be used to estimate definite integrals that cannot be easily solved by analytical methods. There are several methods to apply Monte Carlo integration for finding integrals. In this article we will cover the basic or ordinary method. Basic Monte Carlo Integration Let’s start with a generic single integral where we want …
Monte Carlo simulation can be used for tolerance analysis (Monte Carlo tolerance analysis) to determine the rejection rate of assemblies. In this application we will look at an example assembly where parts A and B must fit inside part C with a clearance fit. For performance reasons we want to minimize the total clearance so …
