The concept of flexible production has been around for several years now. But why are there so few really flexible production systems around? The problem is that flexibility has usually been seen either as a technical or as a human factors issue. It is neither, but both. This paper discusses some questions related to reducing the time, risk and complexity of flexible production line design and cut... View full abstract»
