This introductory paper to the DIISM’04 volume explains the DIISM problem statement and applies principles of architecture descriptions for evolutionary systems (IEEE 1471–2000) to the information infrastructure for engineering and manufacturing. In our vision, knowledge and skill chains depend on infrastructure systems fulfilling missions in three kinds of environments: the of society and its production systems as a whole, the for a scientific discipline, and the , which includes the operational entities (companies, organizational units, engineers, workers) in engineering and manufacturing.

The relationships between these different domains are captured in a An information infrastructure that enables responses to global challenges must draw on a wide range of both industrial and academic excellence, vision, knowledge, skill, and ability to execute. Responses have a scope, from the company, the and the engineering office to collaboration and to collaboration. In all scopes a system can offer services to different operational levels: , development or , and . The dimensions of scope and service level are briefly explained in relation to the architecting of an infrastructure. Papers are grouped according to their contribution to an infrastructure scenario or to an infrastructure component.

In this paper, the creation of ontology of manufacturing features for the development of a feature library is described. The designer’s intention described in functional data of the feature constructing face elements is considered for the creation of the ontology. The creation of the manufacturing feature ontology is intended to make the feature library be useful for the extraction of manufacturing information for process plans generation.

A planning method for linear object manipulation, especially knotting is shown. At first, topological states of a linear object are described. Next, transitions between states are defined. Then, we can generate possible sequences of state transition, from which, we can choose an adequate path from the initial state to the objective state. Furthermore, a method to determine the grasping points is proposed. In the fourth, a planning method is proposed. Finally, our system based on proposed methods is demonstrated

Production cost is one of the most important factors for manufacturing. The production cost associated with each machine tool is calculated from total cost of factory in general. The operation status of machine tools, however, is different, so accurate production cost for each product can’t be calculated. Hence, accounting method of production cost for machine tool operation is proposed using the concept of Activity-Based Costing and is embedded to virtual machining simulator for the cost prediction.

Product lifecycle modelling is to define and represent product lifecycle data and to maintain data interdependencies. This paper presents a framework of product lifecycle model that comprises three parts: product information model, process model based on product life cycle, and extended enterprise resource model. Further, the relationship and formation of product models at different stages are described. Finally, an integrated information architecture is proposed to support interoperability of distributed product data sources.

In the conventional system development life cycle (SDLC), the system performance evaluation phase comes after the implementation phase. Our strategy is to project system performance estimate at the requirement analysis and design phase itself much before the implementation phase. To achieve this objective, we propose a technology-neutral integrated environment for the core life cycle of system development. This core life cycle consists of three phases: system modelling, performance evaluation and performance improvement.

This paper describes an implementation of the Integrated Process Management System, which includes manufacturing process management for building parts, and also construction process management at construction site. To observe the flow of the building parts, RFIDs are stuck to all parts to be managed, and several checkpoints, which we named “gates”, are introduced within the coherent process through part-manufacturing and building construction. The requirements of the RFID directory services are also discussed.

We propose the effective tools of operation standardization for mass production of a new product. The cycle of operation standard consists of three stages of design, improvement and evaluation, and divided into seven steps, that is, decision, communication and understanding, observance, supervision, notice, decision again, and evaluation. The proposed seven tools of operation standardization (OS7) correspond to these steps. These tools enable us to realize mass production of a new product and to stabilize a product quality much earlier.

A key requirement for a successful facility planning and design is to become suitable for new use as well as to be adaptable for new products, technologies or capacities. The software solution “Workbench” is designed for an Information Infrastructure System for the planning of large logistics networks as well as for the network structures of the facilities in an enterprise. The “Workbench” ensures a better information flow and basis for Factory planning and enables planners without great expert planning knowledge.
