Summary: | 碩士 === 國立交通大學 === 工業工程與管理學程碩士班 === 90 === Manufacturing Executing System (MES) plays a pivoting role between Enterprise Resource Planning (ERP) layer and manufacturing equipment at the shop floor. Today MES modules are pervasive in automated factories, but we have also observed the phenomenon of diminishing MES-dedicated software vendors. In this thesis, both conflict-like phenomenons are studied from the tranaction cost viewpoint. In other words, many interface or adaptor designs are inevitable for integrating various products at the ERP layer and distinctive manufacturing equipment because the potential buyers may have different combinations in both ends. However, if the MES-dedicated software vendors can be acquired or merged into ERP or manufacturing equipment vendors, then such extra costs for designing interfaces or adaptors become a redundancy. A tranaction cost reduction analysis gives a clear explanation for the co-existence of the pervasiveness of MES modules and the diminishing phenomeons of MES-dedicated vendors. Moreover, this offers an evolutional interpretation for the emergence and extinction of most MES-dedicated vendors.
