An initial fragment of a core ontology for the manufacturing domain is presented and motivated. It consists of an ontological classification of ADACOR concepts according to the DOLCE foundational ontology. The ontology is conceptually transparent and semantically explicit thus suitable for information communication, sharing, and retrieval. The system here described considers entities performing...

Affected by globalization and increased complexity, supply chain managers have learned about the importance of Sales and Operations Planning (S&OP). However, in large scale supply chains, S&OP has received little attention, by both academics and practitioners. The purpose of this manuscript is to investigate the advantages of S&OP process using a mathematical modeling approach in a large scale ...

Manufacturing systems can be very complex and are often costly to develop and operate. Simulation technology has been shown to be an effective tool for optimizing manufacturing system design, operations, and maintenance procedures. However, each manufacturing simulation is usually developed to address a specific set of industrial issues, and may only apply to a small portion of a complex manufa...

THE FLANGED-ELEMENT MANUfacturing workshop at Dassault Aviation’s plant in Argenteuil, France, uses a number of short-run manufacturing cycles to produce small quantities of numerous aircraft structural parts. The many manual finishing operations, components, and manufacturing processes involved place a premium on management flexibility and quick reactions for meeting ever-changing production d...

Two separate topics of work are outlined: methods for the measurement of chlorinated monomers in PVC and polychloroprene, and also methods for the measurement of these materials in factory air. Typical results which have been obtained in supplies of raw materials, in finished products, and in the working atmosphere at manufacturing operations are given. The second topic concerns the measurement...

Integrated development of machining and inspection plans is essential in dynamic manufacturing environments, especially when right first time manufacturing is required. In this work, a methodology, based on a new and extended use of tolerance charting, that allows incorporation of in-process inspection operations to improve process plans is presented. The methodology proposes the transfer of th...

To amount to a new industrial revolution, the technological changes brought by additive manufacturing must go side by side with new operations management practices. What will these practices be, that fully reap the gains from additive manufacturing? The case study of a firm adopting this technology offers some preliminary answers.

Quality management (QM) has often been advocated as being universally applicable to organizations. This is in contrast with the manufacturing strategy contingency approach of operations management (OM) which advocates internal and external consistency between manufacturing strategy choices. This article investigates, using the case-study method, whether customer focus practices—a distinctive su...

In this paper, we discuss scheduling problems in semiconductor manufacturing. Starting from describing the manufacturing process, we identify typical scheduling problems that can be found in semiconductor manufacturing systems. We describe batch scheduling problems, job shop scheduling problems, scheduling problems with secondary resources, multiple orders per job scheduling problems, and sched...
