Description:This is a good overview of the SNP Optimizer and other modules in APO. It also goes into other optimization models (outside SAP), and has valuable examples of these in industries where optimization modeling long preceded SAP and SAP APO like the chemical and petroleum industries. Walking through the decisions of how these clients decided to either convert their models to an SNP implementation or use the external model as a bolt-on (the authors and SAP people prefer the term "plug-in") was enlightening. This book will save you some grief in the decision-making process up-front, but it is not a how-to manual. At the time of writing the authors did not know of many live implementations of the SNP optimizer. The focus is on pre-implementation decisions and implementation. There is a lot of talk about what in SNP is technically possible, but not advised and could yield an impractical implementation. The book provides a good perspective for experienced practitioners of optimization modeling.
