244 Implementation

A schematic diagram of the architecture is shown in the Figure 24.3. The first web service allows the user to browse through and select any of the registered data sources. The second web service transforms the selected data source into a PLCS-XML compatible file. This web service maps the proprietary data model of the source application onto the PLCS standard data model using XSLT. The knowledge of the data mapping is encapsulated in the XSLT files and therefore easy to change and adapt for any...

442 Tradeoff between Worth and Cost

We consider, for the sake of simplicity, a product composed of three kinds of parts a, b, and c. Each of these parts has two kinds of grades 1 and 2. Then, eight kinds of products can be considered in accordance with the cube of two as shown in Table 44.1. Roughly speaking, the cost is defined as the sum of the cost of each part for eight kinds of products. On the other hand, Worth at the component level increases if the grade is higher. However, unlike the case of a CPU, Worth is not always...

103 Concept of Product Genome

Comparing with organism, we can take a product as an organism - a complex assembly of different kinds of cells that perform many different functions, - and a part of the product as a cell the smallest structural unit of an organism that is capable of independent functioning. The rapid and automatic growth of organisms is a fascinating process, which lead to the idea of product gene. To get a scientific definition of Product 'Gene' (PG), firstly we need to investigate gene and the mechanism of...

162 The Overall Strategy

For reasons of clarity and simplicity, we already introduced a brief vocabulary about the variables (see 9 ) and constraints (see 11 ) involved in an elementary design analysis loop (see Figure 16.1). Basically, a design concept may be structurally defined by a number of Design Variables (DVs) which might be sufficient to assess the current Performance Variables (PVs) of the studied concept. These latter PVs are compared to the expected performances, namely the Functional Performances (FPs)....

Analysis of the Product Development Paradigms

The analysis above outlines the current situation of manufacturing and further implies its influence on product development. The current production paradigm has the following features. First, due to the ever-developing globalisation and universally developed market principles, we now see different forms of division in manufacturing. One is competence-based division of manufacturing and the other is geographical division. Both forms of specialization require integration through advanced...

Systematic Design Approach for Reconfigurable Manufacturing Systems

ElMaraghy Abstract The evolution of manufacturing systems is triggered by the dynamic customer environment of its time. The main characteristics of today's customers' environment are mass customization and responsiveness to market demand and thus the reconfigurable manufacturing system was suggested for such environment. This paper presents a systematic approach for the design of reconfigurable manufacturing systems and how to control that design process through...

215 Example

The example that illustrates the proposed concepts is developed in the IPPOP project. It concerns the design of the fixing between the rack-and-pinion and the support of a translation system of a bowl on a mixer. This design phase is representative of the needs for collaboration that could appear during a design project. Three design actors are involved to co-design the fixation a design expert, a manufacturing expert and a material expert. In our example, IPPOP identifies that the third expert...

212 Collective Work Analysis

Collaborative design process is not prescriptive, even though a nominal process could be defined. During collaborative work, the designers' tasks are performed in parallel and their results should be convergent to satisfy design objectives. These objectives could be refined as the design project progresses. Therefore, it is important to understand the collaborative design process to be controlled. Rose et al., 6 propose to study the various works performed by co-designers and their occurrence...

43 Setbased Concurrent Engineering

Ward and his co-authors argue that in concurrent engineering there are two fundamentally different approaches to be recognized point-based and set-based. In case of point-based design, a single solution is synthesized first, then analyzed and changed accordingly. Even though the phases of the design process may be executed concurrently, all designers and specialists are investing their efforts in the pursuit of only one concept that is to be developed into a solution. In set-based concurrent...

Value Chain Structure and Correlation Between Design Structure Matrices

Marco Cantamessa, Maurizio Milanesio, and Elisa Operti Abstract An empirical study of the relationship between product architecture and industry structure is discussed. Product architecture is modeled by using Design Structure Matrices DSMs representing three different types of inter-component relationships technological homogeneity, functional interaction and assembly process contiguity. The DSM models may be used to explain firms' specialization choices within an industry. Moreover, the same...
