To meet the challenge of the 1990's and beyond there is a need to adopt advanced manufacturing technologies and new manufacturing techniques. In particular, there is a growing recognition of the need to develop a more holistic approach to the organisation of the business and the computer technologies it uses. One label often applied to this approach is CIM (Computer Integrated Manufacturing). T...

MOTIVATION Two-stage pilot and integrated designs are powerful tools for investigating large numbers of hypotheses. Asymptotically, optimal two-stage designs controlling the familywise error or false discovery rate are considered when costs and effect sizes per measurement differ between stages and total costs are constrained. RESULTS Depending on the cost and effect size ratios between the m...

The concept of Rapid Manufacturing (RM) is emerging from the so-called Rapid Prototyping technologies where additive rather than subtractive techniques will be used to make parts or even completed assemblies. As no tooling is required, one of the main benefits of RM will be the ability to make cost-effective custom products that could all be entirely individualised to a particular consumer or u...

In this paper an analysis of the Common Information Model (CIM) standard for object-oriented information specification in network and system management is given, including a short discussion of several important potential benefits and open issues, and a presentation of original extensions of the standard solutions to some open issues.

Our research focused on the analysis of face-to-face (FTF) social interaction of groups working on maths problems using the GCC framework in traditional classroom setting. The GCC framework requires students to analyze maths problems with "solutions" that contained conceptual or oversight errors, critique these solutions with mathematical arguments, and finally fix the "solutions" collaborative...

1 Testing in an Integrated Circuitry Since the existence of integrated circuitries, there has been the necessity to check their functions. In the case of digital circuitries, a test is quite simple: all possible test vectors are applied in succession, and then the circuitries’ reactions at the outputs (actual value) are compared to the expected patterns (nominal value). If there are no differen...

The usage of multi-agent systems for manufacturing control seems to be sharply contrasted by classical mathematical control theory. This work emphasizes how views from both scientific fields can be combined to create the flexible and optimal manufacturing control systems of tomorrow.

Reconfigurable machines form a new class of machines that are designed around a specific part family of products and allow rapid change in their structure. They are designed to allow changes in machine configuration according to changes in production requirements. The reconfiguration may be related to changes in machine functionality or its scalability, i.e., the change in production volumes or...

PDM Systems contain and manage heavy amount of data but the search mechanism of most of the systems is not intelligent which can process user‟s natural language based queries to extract desired information. Currently available search mechanisms in almost all of the PDM systems are not very efficient and based on old ways of searching information by entering the relevant information to the respe...

This paper discusses the conceptual structure and implementation of an integrated, computer-aided manufacturing system design environment, known as I/O-CAMSD (integrated and open computer-aided manufacturing system design). The work has provided valuable information to prove the feasibility of developing an integrated CAMSD framework to support the complete cycle of manufacturing operation—from...
