Abstract
The aim of the programme was to develop a concurrent
design and planning system that would integrate product
design, production planning and the planning of changes
to the production systems. This integration was based on
a uniform product model describing all product
characteristics and a factory model describing all
manufacturing resources. The application domains were the
engineering industry and the graphic arts industry.
Product modelling in the engineering domain was
accomplished using features and additional attributes.
The functional and manufacturing significance of a
feature enables it to be used as a descriptive unit that
facilitates integration. This unit is defined in ever
greater detail as the design process moves from one stage
to the next. The product model was implemented as an
application protocol conforming to the STEP standard (ISO
10303). The product description was stored in an
object-oriented database, from which links to all the
system's computer-aided applications were implemented
through a single, common inquiry interface. A particular
development effort was made in the process planning of
chip-forming machining. The same approach was used in the
graphics arts industry application. In that case the work
focused on the creation of models and mechanisms allowing
progress from the product design of graphic arts products
to production planning and cost optimization.The
applications were augmented by product data management
solutions developed in the programme. A computer-aided
method was developed in order to manage the necessary
production adaptions caused by changes in products and
product range.
