We demonstrate the use of reconstructability analysis (RA) on the UCI Australian Credit dataset to reduce the number of input variables for two different analysis tools. Using 14 variables, an artificial neural net (NN) is able to predict whether or not credit was granted, with a 79.1% success rate. RA preprocessing allows us to reduce the number of independent variables from 14 to two different sets of three, which have success rates of 77.2% and 76.9% respectively. The difference between these rates and that of the 14-variable NN is not statistically significant. The three-variable rulesets given by RA achieve success …
Simulation As A Tool For Evaluating Strategic Policies For Flexible Supply Chain Systems, Janice L. Forrester, Wayne W. Wakeland
Simulation As A Tool For Evaluating Strategic Policies For Flexible Supply Chain Systems, Janice L. Forrester, Wayne W. Wakeland
Systems Science Faculty Publications and Presentations
The emergence of flexible supply chain systems (FSC) has sparked increased interest in real-time planning, scheduling, and logistics--with particular consideration for strategic implications and overall cost control. Important aspects of an FSC include forecasting, production, materials handling, transportation, and distribution center inventory. There exists a variety of software applications for addressing tactical issues, such as adaptive scheduling, and short term forecasting. However, these programs typically do not permit the user to assess the strategic implications of different policies for flexing capacity and making alternative commitments to manufacturing plants. Recently there has been increased interest in the use of simulation models …
