AbstractSupplier of system components face the challenge of customer requirements influencing the property level functional integral product architectures. For this, solution approaches focusing on the re-use of pre-engineered part variants are not applicable. However, to generate a valid product structure, customer-specific properties have to fit modelled product knowledge. Therefore, the approach models a reference class structure and analysis compatibilities on the property level for customer specific inputs concerning explicit product knowledge and constraints.

Abstract Industrial enterprises see themselves confronted with a complexity of products and production processes, which became almost uncontrollable. Individualization and globalization of the demand will continue to increase, so that the existing variety of the product variants presumably cannot be reduced significantly. Attainable are however a strong weakening of the variety increase and a reduction of the internal complexity. Results from numerous analysis projects in the automobile industry show that substantial potentials (on the average 64%) for the reduction of the complexity are present in areas without impact on the degree of fulfillment of customer requirements (engine, axles, raw body, etc.). Even higher potentials are realizable by an intensive cooperation between manufacturers and suppliers. This paper introduces the Variant Mode and Effects Analysis (VMEA), which is a proven method to reduce the number of variants and, therefore, the complexity and complexity-related costs throughout the whole development and manufacturing processes. The method includes a systematic analysis of market requirements and a systematic assignment of market requirements to product functions, modules and parts, thereby enabling the user to develop a modularized, market-oriented product structure designed for meeting the market demands with the smallest number of product variants possible. The results presented in this paper were obtained in a series of twenty cooperation projects involving ten medium-sized German manufacturers of cars and automotive supplies, among them Audi AG, BMW AG, Volkswagen AG, Volvo and Micro Compact Car.

Configuration Systems

Companies applying mass customization paradigm regard the design process as a configuration task where the solution is achieved through the extraction of a new instance from a modular product structure. In this context product configuration management tools are evermore important. Although tools have been already proposed, they fail in real industrial contexts. Main causes are recognizable in high efforts in systems implementation and lack of flexibility in products updating. This research aims to develop an approach to overcome drawbacks and simplify the implementation and the use of product configuration systems also in redesign activities. The paper initially reviews existing systems in terms of design knowledge representation methods and product structure formalization techniques. Then, an approach based on Configuration Virtual Prototypes which store and manage different levels of knowledge, is presented. In particular, a framework is outlined in order to represent design data and its formalization in configuration tools. Three different domains are managed and connected via Configuration Virtual Prototypes: Product Specifications, Geometrical Data and Product Knowledge. Specifically, geometrical data aspects are analyzed in detail providing approaches for eliciting knowledge introduced by parametric template CAD models. The approach will be exemplified through a real application example where an original tool has been developed on the based of the described method. Benefits of the system will be shown and briefly discussed, in particular in terms of reachable flexibility in solutions.

Requirement Specifications

Over the years a lot of strategies emerged to enhance efficiency throughout the product lifecycle of complex products: knowledge management, platform and module strategies as well as integrated requirements management are only a few of the existing product lifecycle management (PLM) strategies. An integrated product model is seen as the backbone of PLM management strategies. Most product structuring approaches propose to develop a functional structure first, considering the given requirements. From this a product structure is derived, which is finally filled with developed parts and assemblies (bill of material, BOM). In early product development phases there has to be a common understanding among the involved departments and domains about the future product appearance. Products based on platform or modular strategies have a high proportion of reused parts and assemblies. Besides, new parts have to be identified, prioritized and developed according to their priority. For this process a reliable, interdisciplinary product structure is essential. Hence, an early bill of material is used to integrate engineering tasks in early development phases and to shorten identification as well as prioritization efforts. This paper proposes an approach to derive an early bill of material from requirement specifications semi automatically.

The purpose of this study is to examine the effect of prestige sensitivity on mobile phone customer’s price acceptance in Vietnam and the mediating role of product knowledge and price mavenism on this relationship. We used the convenience sampling method for data collection via questionnaires with a sample of 605 consumers who purchased mobile phones. The collected data was analysed by applying a structural equation modelling method. The result indicates that prestige sensitivity has both direct and indirect effects on price acceptance via product knowledge and price mavenism. The findings suggest that prestige sensitivity can be used as a market segmentation criterion for mobile phones when making price decisions and providing customers with adequate information could improve price acceptance.

House Building

This book seeks to explain how the Corporation of Glasgow, in its large-scale council house-building programme in the inter- and post-war years, came to reproduce a hierarchical Victorian class structure. The three tiers of housing scheme which it constructed – Ordinary, Intermediate, and Slum-Clearance – effectively signified First, Second and Third Class. This came about because the Corporation uncritically reproduced the offensive and patriarchal attitudes of the Victorian bourgeoisie towards the working-class. The book shows how this worked out on the ground in Glasgow, and describes the attitudes of both authoritarian housing officials, and council tenants. This is the first time the voice of Glasgow’s council tenants has been heard. The conclusion is that local council housing policy was driven by unapologetic considerations of social class.

High Influence

Fuel price crisis has caused people to demand a car that is having a low fuel consumption without compromising the engine performance. Designing a naturally aspirated engine which can enhance engine performance and fuel efficiency requires optimisation processes on air intake system components. Hence, this study intends to carry out the optimisation process on the air intake system and airbox geometry. The parameters that have high influence on the design of an airbox geometry was determined by using AVL Boost software which simulated the automobile engine. The optimisation of the parameters was done by using Design Expert which adopted the Box-Behnken analysis technique. The result that was obtained from the study are optimised diameter of inlet/snorkel, volume of airbox, diameter of throttle body and length of intake runner are 81.07 mm, 1.04 L, 44.63 mm and 425 mm, respectively. By using these parameters values, the maximum engine performance and minimum fuel consumption are 93.3732 Nm and 21.3695×10-4 kg/s, respectively. This study has fully accomplished its aim to determine the significant parameters that influenced the performance of airbox and optimised the parameters so that a high engine performance and fuel efficiency can be produced. The success of this study can contribute to a better design of an airbox.
