Title: Using a Computer Simulation Model To Demonstrate Effects of Ingredient Measurement Bias in Volume Recipe Production
Abstract: A sample data set consisting of selected recipe production/ingredient data and supporting inventory/ingredient and unit size conversion data was constructed. A computer application was developed to simulate the "production" of a recipe on an iterative basis. Numerous prototypical parameters were stochastically generated from normal distributions defined by given actual or hypothetical means and standard deviations based on the production environment. A series of "rules" were provided for converting computer data-base recipe ingredient quantities with real-number precision of 15 significant digits of accuracy to calculated quantities of ingredient amounts in multiples of institutional measurement unit sizes formatted for textual display on printed recipe production documents. Paired t-tests were used to test the null hypothesis between experimental treatments (calculated values of extended ingredient quantities vs. formatted textual display amounts of extended ingredient quantities vs. stochastically generated "actual" measured ingredient quantities) and levels of measurement bias (heaping vs. level vs. scant measuring techniques). By executing the simulation model over hundreds or thousands of recipe "production" iterations, each with stochastically generated variables in measuring techniques, the student or investigator can observe the magnitude of variation in nutrient and/or cost values of these recipes on a per-serving or per-batch basis.
