RAPID prototyping, MANUFACTURING processes, SPECIFICATIONS, MANUFACTURES, and SUPPLY chains
Despite the use of Additive Manufacturing (AM) technologies in a lot of applications including the production of some high-value products for end use, it is still very much an untapped potential. There is an increase in usage of AM technology for the manufacture of end-use products (Rapid Manufacturing (RM)) in recent years, but mass use of the technology in terms of speed, cost and quality, which is acceptable by the general consumer, is still not widely in existence today. The concept of RM as a viable production process is still not understood by many businesses/consumers, with thinking still dominated by the AM technologies for Rapid Prototyping (RP) applications. A key difference between RM and RP is in the supply chain. The RM supply chain is much more complicated than the RP supply chain. This research conducted a Delphi Study to identify the requirements or pre-requisites necessary for the use of RM technologies as a viable means to manufacture end used products (RM application of AM) in mass scale. The paper identifies 36 requirements or pre-requisites and classified them into various classes of importance in order to highlight their significance. In addition to supply chain issues, the requirements unearthed are factors or features about RM technology (equipment), materials and processes that need modification, upgrading or creation.

WORK design, PROTOTYPES, and MANUFACTURES
Although prototyping is a technique widely used in manufacturing industry during the design development and manufacture of a new or updated project, the technique is rarely used to test out options during the design of a manufacturing system. The work organization action simulation was developed in response to a need identified in the training of engineers. Such an approach can be used to prototype sociotechnical systems and explore technical options in association with the organizational structure. [ABSTRACT FROM AUTHOR]

This article reports that rapid prototyping has evolved from a relatively simple modeling technique that allows design engineers to "test" their ideas in three dimensions to a sophisticated custom-manufacturing tool that may one day find its place alongside the copy machines at the local copy center or in the parts department at the local automobile dealership. Direct metal deposition is a laser-melting process that uses a powder nozzle to deposit metal powder onto existing tools to build the components layer by layer. While the last few years have seen the development of new rapid-prototyping technologies and processes that overcome the geometry problem, the available materials have not had adequate properties to enable them to build production-quality parts.

This paper proposes a multi-material virtual prototyping (MMVP) system that integrates the virtual reality (VR) and the layered manufacturing (LM) technologies for digital fabrication of heterogeneous multi-material prototypes for advanced product development and biomedical engineering. The system consists mainly of two algorithms for sequential and concurrent multi-toolpath planning, and a virtual prototyping system. The algorithms adopt a topological hierarchy-sorting algorithm to establish the hierarchy relationship of multi-material slice contours for facilitating toolpath planning of multi-material layered manufacturing (MMLM). Subsequently, the sequential multi-toolpath planning algorithm generates sequential toolpaths that avoid redundant tool movements. To reduce build time further, the concurrent multi-toolpath planning algorithm generates collision-free concurrent toolpaths. Based on the hierarchy information, a bounding box can be adopted to approximate envelopes of contour families of the same material property to simplify detection of tool collisions. The algorithms are integrated to form the MMVP system for planning, stereoscopic simulation, and validation of multi-toolpaths for MMLM. [ABSTRACT FROM AUTHOR]

In an earlier work (Ransing et al . 1995), we represented the causal relationship in a defect-metacause-rootcause form. This representation was perceived to be of considerable importance to the research community as well as industry, as it is applicable to any form of manufacturing process. Based on this representation we proposed 'A Semantically Constrained Bayesian Network' for the diagnostic problems (Lewis and Ransing 1997). In this paper, we develop another popular Artificial Intelligence tool, 'Feedforward Neural Network', for such diagnostic problems. The network is constrained to defect-metacause-rootcause topology and it has been shown that metacause concepts can be successfully associated with the hidden nodes. The errors are calculated at both the output layer and the hidden layer. Although the learning process is based on the back-propagation algorithm with a momentum term, the weight changes would occur at a link connecting a node only if at least one of the nodes connected to it in the preceding layer has non-zero activation. The theoretical analysis of such constrained learning is given and it is shown that the network behaviour is acceptable for the diagnostic problems considered. [ABSTRACT FROM AUTHOR]
The design of a new product usually takes shape gradually over time. Traditionally prototypes follow the design and are concluded before product launch. To decrease the time-to-launch, one may want to start prototype tests in advance of the design completion. However, with a slowly evolving design, modifications (in design) between subsequent prototypes can be significant, thereby increasing the time required for prototyping. This effect would be enhanced further if the prototyping time per unit of design change (sensitivity) is high. Using analytical models, we show how the interaction between the speed of evolution and the sensitivity impacts overlapping strategies. In scenarios where the impact of design changes can only be measured in discrete units, we formulate a shortest-path model and show how discreteness may limit the number of used prototypes.

MANUFACTURES, RAPID prototyping, MANUFACTURING execution systems, PRODUCTION engineering, and INDUSTRIAL engineering
This paper considers the basic Economic Order Quantity model that allows stockouts and backordering. It assumes that the number of defectives produced by the manufacturing process is random rather than constant. Specifically, we assume that each lot contains a random proportion of defective units. Based on this scenario, we adjust the EOQ with planned shortages model for the quality factor. In addition to the general relationships obtained, closed form relationships are also given for the two special cases where the proportion of defectives follow uniform and exponential distributions.
