This paper looks at the communication media and organisational change requirements to support teamwork in a virtual organisation. A large engineering design organisation faced problems of coordinating concurrent engineering activity and geographical distribution. These problems were identified in detail, and the requirement for the design of an integrated communication support system was specif...

In recent years a series of important achievements have paved the way for the introduction of probabilistic analysis in the area of soft real–time systems design. In this paper, we present an extensible design tool – called PROSIT – that facilitates the access to this technology for a potentially large number of researchers and industrial practitioners. The tool enables probabilistic analysis o...

This paper discusses practical development of business rules (BR) systems. The main conceptual foundations of BR are discussed, and selected tools for BR design and implementation are described. An application of a rule-based systems design tool (Mirella Designer) for BR design is proposed. Business rules visual representation using XTT in Mirella Designer is both transparent and compact. The u...

In any metal forming process, both the strain rate and deformation rate depend on the die profile. The die profile also, is responsible for the non-uniformity of the deformation along the cross-section. These affect the quality and mechanical properties of the product. Therefore, if a die is designed, in which the affecting variables can be controlled spontaneously it is hoped to obtain a produ...

one of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. as a result, the tool would be worn and its life time would be reduced. therefore, in long time machining, it is essential to change inserts and tools, continiously. a milling tool with self rotary cutting inserts was designed and manufactured that enables i...
