With the rapid development of global economy, enterprise needs to introduce advanced theories and methods, such as industrial engineering, to evaluate and improve production line. Taking turbocharger assembly line of a factory as an example, using Delphi theory and hierarchical analysis method, according to questionnaire results of experts and skilled operators, establishes the evaluation factors and their weights, obtains dimensional functions of each evaluation factor, get parameter values by experimental ,thus forming the assembly line performance evaluation model. Finally, evaluates the tu...
