This research effort focuses on improving the flexibility of production engineering for manufacturing industry by means of providing technological alternatives. A new generation of NC simulators required supporting the decision making of production engineering. In this paper a conception of NC simulator trying to fill this gap is given. This is a step forward realising Virtual

To fully unders tand a sequence of u t terances , one must be able to infer implici t re la t ionships be tween the ut terances . Al though the ident i f ica t ion of sets of u t terance relat ionships forms the basis for many theories of discourse, the formal iza t ion and recognition of such relat ionships has proven to be an ext remely difficult computa t iona l task. This paper presents a p...

A value/risk -based performance evaluation framework is proposed in the context of manufacturing processes at the industrialization phase of product development. Various risk factors of the manufacturing process are identified through Failure Mode and Effect Analysis (FMEA) and then embedded in the process plan models. Modelling and simulation are then employed for determining the value a proce...

Plan libraries are the most important knowledge source of many plan recognition systems. The plan decompositions they contain provide information about how a plan has to be executed to actually achieve its associated goals and be recognized by the system. This paper presents an approach to the automatic acquisition of plan decompositions from sample action sequences. In particular a clustering ...

The paper deals with the intelligent functional model for optimizing the product design and its manufacturing process in hybrid manufacturing systems consisting of people, machines and computers. The knowledge-based framework of an intelligent functional model has been developed. It furnishes the possibility for a product designer and manufacturer to find an optimal production plan in the early...

Developing a lesson plan (or syllabus) for a course can be a very time consuming process. Once the instructor has a pool of topics to be taught in the course, the organization of those topics in a form that facilitates understandability by the students as well as efficiency with respect to the order of presentation can be an elusive task – many times considered to be an art that distinguishes g...
