Views and Experiences of Configuration Management

Product configuration is an issue related to evolution of software tools, business paradigms and product structuring. Experiences on developing software solutions for configuration purposes date back to 1980s, when first configurators were introduced. Since then a lot of experience from implementing configurators has been gained.

Open Product Development

Open Product Development Methodology is the future of design methodology. It contains three phases: 1. Proactive, strategy-based construction of product development knowledge 2. Fast, efficient product development utilising the right resources 3. Guarantee of product life-cycle knowledge. Each phase has its own methods, of which the following are presented in this chapter: Company Strategic Landscape, Product Family Design and Configuration Process, and the Combined Variation of Product, Manufacturing Processes and Networks. It is important to strengthen the head designer’s role and that the Product Architect takes new responsibilities in design, such as in the environmental review stage.

Landscape for analysing the business effects of utilizing design support simulations

Advanced design support solutions such as 3D simulations have enabled improved management of design information for years. The challenge, however, is that acquiring these type of design support solutions does not necessarily create a visible business value for the company in a short run. Moreover, the organization surrounding the simulation solution should support its use by providing the conditions and resources needed for utilizing it. Vice versa, design support solutions have to support the prevailing organizational conditions. Especially the interaction between the planned design-support solution, existing process structures and human related issues have to be understood to create the basis for business efficient design information management. Understanding the chain effects of employing different types of design support solutions has on organizational “ecosystem”, creates basis for forming business-effective sustainable communication and design support structures. The Company Strategic Landscape introduced will form the framework for recognizing these chain effects in business environment.

Case study of tribology at tampere university of technology: percussive rock drilling tube

Abstract The aim of this study was to research the problem of wear localized on the thread joint of a percussive rock drilling tube. Wear of the thread joint causes a decrease in the tightness of the joint and increases the sensitivity of the tube to breakdown. The effect of wear of the thread joint on the endurance of a drilling tube was studied using failure follow-up. As a result of failure follow-up, it was found that the endurance of a drilling tube is primarily dependent on the properties of the material used. The mechanism of wear was studied using replicas and a scanning electron microscope. Three different wear mechanisms were found in the thread joint. The prevalent wear mechanism depends on the fixing moment of the thread joint and the location of the wear phenomenon. Impact wear can be considered to be the dominating factor in the wear process.

Three-dimensional measurement method (CADMM) for the realization of process plants

Abstract In the process plant construction industry the lack of metrology has prevented automation of site assembly work. In this paper we present a high-level metrology system for process plants. The measurement model of a process plant is a 3-D model which shows global coordinates, fixed points for measurement, and detail tolerances for compensating inaccuracies inside and between disciplines. Appropriate measurement techniques are considered as well as recommendations for further research.

PRODEAL, Technology Programme for the Development of Process Plant Construction

SUMMARY Process plants form a major part of Finnish heavy metal industry production, accounting for annual sales of US

MODELING CONFIGURABLE PRODUCT FAMILIES

10 billion, while process plant deliveries represent over 50% of Finnish exports. A number of major companies of the Finnish metal industry have started a technology development programme to utilize the latest computer-integrated manufacture (CIM) technologies for the enhancement of process plant realization. In the programme, research and development is carried out in projects. This paper presents some on-going projects related to modelling of the plant delivery process, the management of design changes, and the metrology for process plants. As research proceeds, new research projects have been planned; we have described estimation, simulation and optimization projects. The use of artificial intelligence facilitates the application of new technology.
