Product modularity for life cycle design

Modular design is an important elemental technique in life cycle design for improving, e.g., maintainability, upgradability, reusability, and recyclability. Appropriate modular structure differs according to applied life cycle options; e.g., while the modular structure for recycling should be based on material kinds, the structure for upgrading should be based on functions to be obsolete. This paper proposes a method for determining modular structure by aggregating various attributes related to a product life cycle and evaluating geometric feasibility of modules. This paper also illustrates the prototype system that implements the proposed method and a case study of a printer.

Open-architecture products

This paper defines open-architecture products (OAPs), a new class of products comprising a fixed platform and modules that can be added and swapped. Customers can adapt OAPs to their needs by integrating modules into the platform. Manufacturers will produce these platforms, while new small companies and customers will develop the modules, thus increasing employment and causing the economy to flourish. At the same time OAPs will provide consumers with the product they desire. Challenges include developing new OAP design software for non-professional designers and new assembly systems to facilitate economical assembly of a large number of product variants.

Focussing product innovation and fostering economies of scale based on adaptive product platforms

Current concepts to achieve product commonality follow static approaches. To achieve economies of scale, standards are defined across the product program. However, these standards typically need to be compromised at new product introductions due to unforeseen innovations and economies of scale decrease over time. Accordingly platform standards need to be re-defined.This paper presents an approach for adaptive product platforms. Degrees of freedom in product and process design are managed pro-actively based on functional and technological models. This way adaptivity towards product innovation can be ensured. The concept of adaptive modular platforms is explained based on a practical application.

Co-Evolution of Product Families and Assembly Systems

To cope with the intense global competition that is characterized by high product variety and short life cycles, manufacturers need to share manufacturing systems across products and product generations. Co-evolution of product families and assembly systems is proposed as a novel methodology for the joint design and reconfiguration of product families and assembly systems over several product generations. The co-evolution methodology capitalizes on the opportunities for design and assembly system reuse that are offered by modular product architectures and reconfigurable assembly systems. As a result, co-evolution can lead to reduced product development costs and increased responsiveness to market changes.     

Scenario-based determination of product feature uncertainties for robust product architectures

Modular product architectures are used by many firms today to achieve a high degree of product differentiation whilst reducing cost through economies of scale. At the same time, the firms are increasing architecture lifetimes to 10 years or more, which brings up new challenges for the development process. Uncertainties regarding future product features need to be anticipated when designing the architecture to minimize modification efforts. Nevertheless, existing approaches for designing modular product architectures are mainly based on static requirements and thereby neglect the dynamics of the market that influence future product features. This paper aims at presenting a method utilizing scenario-planning and simulations in the product range planning process to determine future product features and their uncertainties as a basis for the product architecture design. Possible feature specifications are derived from product environment scenarios and linked to the factors influencing the scenarios, to calculate their expected values and deviations.

Modularity,Combining and Artificial Neural Nets

In this paper, the modular combination of artificial neural nets is considered. A modular approach to combining can be contrasted with an ensemble-based approach in that it implies individual modules, each responsible for some specialist aspect of a task, as opposed to each approximating the same function. It is possible to characterize modular systems in terms of (i) reasons for the task decomposition, (ii) the method for accomplishing the decomposition and (iii) the relationship between the modules. These characteristics are considered in brief outlines of the papers in the issue. Reasons for task decomposition include the exploitation of specialist capabilities of individual nets, performance improvement, and making the system easier to understand and modify. Task decomposition may be either automatic (based on the blind application of a data partitioning algorithm) or explicit (based on prior knowledge of the task or the specialist capabilities of the modules), and the relationship between the modules may be successive, cooperative or supervisory.
