Scheme decision analysis between physical prototype and virtual prototype for laser

Technology scheme decision is a complex process for a real laser product.Usually,qualitative analysis and logical judgement are used in this process.It's difficult to analyze in quantitive way.With high power crosscurrent CO2 laser as an example,analysis of hiberarchy process(AHP) is used for decision process between physical prototype(PP) and virtual prototype(VP) in a quantitive way.Through analyzing mearusures,criterias and target in hiberarchy,the quantitive comparative relation between PP and VP in criteria layer and target layer are obtained and it is used to make shceme decision.Results show that it's better for laser development with PP than VP.
