Roger Maris Case Study – Using Quantum XL to Define Multiple Inputs Simultaneously

Quantum XL’s bulk input/output feature allows the rapid creation of models with large numbers of inputs. To demonstrate how to use this feature, we will use Quantum XL to analyze the record 1961 season of Roger Maris. In 1927, Babe Ruth hit 60 home runs, setting the single season record that would stand for more than […]

Optimization (Robust Design) using Quantum XL

Quantum XL’s optimizer provides the unique ability to minimize the defects per million (dpm) across multiple outputs in a model. The optimization is a true stochastic optimization, which means that the inputs are all modeled with probability distributions. This article explains how to use Quantum XL’s optimizer. This article builds on the concept of an

Quantum XL Latitude Plot Part A vs Part B

Understanding Latitude Plots – Part I

Quantum XL‘s Latitude Plots are a visual depiction of the relationship between the expected variation and the latitude window. If used properly, Latitude Plots are an exceptional communication technique, but can be confusing to the uninitiated. This article introduces Latitude Plots and explains how to read them. To serve as an example, we will use

Kano’s Model Case Study Based on the Cruise Line Industry

Introduction Recently, I had the opportunity to take my family on a Royal Caribbean® cruise for our summer vacation. We had cruised in the past with Disney®, which led to an inevitable comparison of the quality of the two cruise lines. While on the Royal Caribbean cruise, I realized that the dichotomy between Disney and
