The labor–machine dyad and its influence on mix flexibility
在PCB组装厂实证检验了劳动柔性和机器柔性对混合柔性的联合、中介和交互效应，发现追求完全柔性不可取，高劳动柔性时增加机器柔性反而适得其反。
Abstract The joint, mediating, and interactive effects of three elements of labor and machine flexibility on mix flexibility were tested empirically in a PCB assembly plant. Both subjective and objective data were collected. Some elements of labor and machine flexibility mediated the relationship between an emphasis on competitive priorities and mix flexibility. The interactive effects of machine and labor flexibility on mix flexibility confirmed prior findings that the pursuit of total flexibility is not desirable. For low levels of labor flexibility, increasing machine flexibility yields at the most a very moderate improvement in mix flexibility. When labor flexibility is high, increasing machine flexibility proves to be counter‐productive. These results may suggest that the traditional forms of labor flexibility need to evolve when technological capabilities are more fully exploited.
