An Inter-industrial Comparison Study on the Benefits of Production Information Systems
نویسندگان
چکیده
We exercised a cross comparison analysis on the linkage among computer-based information technologies utilized for production activities, perceived benefits of production information systems, and competitive performance of each plant, using the database for 164 manufacturing plants located in five industrialized nations from three industries (machinery, electrical & electronics and automobile), which had been established through an international collaboration on high performance manufacturing research. Information technologies we took up for the analysis include CAD, CAE, CAPP, LAN, FMS, automated retrieval and storage, MRP, simulation tools, SPC software, database for quality information, and EDI linkages among others. The benefits of production information systems were measured in terms of manufacturing cost reduction, quality improvement, lead time reduction, increase in flexibility to changing product mix and production volume, and new product introduction time reduction. We found that there are remarkable differences in the linkage structure among industries.

Optimization of two-stage production/inventory systems under order base stock policy with advance demand information
It is important to share demand information among the members in supply chains. In recent years, production and inventory systems with advance demand information (ADI) have been discussed, where advance demand information means the information of demand which the decision maker obtains before the corresponding actual demand arrives. Appropriate production and inventory control using demand info...

متن کاملDetermining Maintenance Opportunity Window (MOW) in Job-Shop Systems by Considering Manpower of Maintenance
Nowadays, production systems seek to integrate production and maintenance activities. An effective maintenance plan can improve maintenance stability and system performance. Machines that stop for repairing operation impose a high cost on the system. On the other hand, there are always some intangible situations during a production process in which repairing activities can be carried out. If th...
متن کاملIntegrative Cell Formation and Layout Design in Cellular Manufacturing Systems
This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...
