The attempts for essential lowering expenses of the equipment without narrowing of a range of manufacturing system technological possibilities have resulted in the concept of compact production. The compact manufacturing system is a human-machine complex combining a curtailing in space and time with a minimum level of a structural and resource redundancy, supported by highly intelligence tools of computer aided design and control.

The collective method of project decision making is effective in the given situation. The interaction of the adjacent subjects in concurrent designing has conflict character. The problems of understanding, mutual understanding and argument have an exceptional value in these conditions. The sign systems used by the different subjects have professional specificity and differ, in particular, amount and sort of a non-verbal component. Such sign systems connected among themselves will derive a semiotic field. The collection of semiotic fields within the space of which the design activity of the subjects is carried out will derive a local universal semiotic set. The solution of conflicts between the mutually co-operating subjects represents a semantic invariant of appropriate semiotic fields of a universal set. Thus the semantic invariant of product finds the reflection in semantic spaces of the subjects as professional senses at each stage of a production cycle. So product undergoing natural transformation and appearing consistently as the "object of necessity" - "object of designing" - "object of production" - "object of sale/purchase" - "object of consumption (maintenance) " during its living cycle.

It is possible to tell geometrical analogy, that the professional sense of a semantic invariant of production represents some area in the appropriate n-dimension co-ordinate semantic space of each of the subjects. The transition from one semantic space to other can be formally described with the help of a tensor. The same tensor analogy is fixed in a basis of a CAD database. The extended tensor algebra is relative complete. However, alongside with structural transformations of the attitudes (as well as relations) carried out by traditionally relational algebra tensor algebra works with the quantitative characteristics, that makes this formalism more powerful and perspective for use for modelling in CAD information systems.

Tensor approach to modelling and organisation of information support of collective intelligence system allows to carry out both a direct transition from one space to another and a "roundabout" way through components of a tensor database of a lower level, i.e. with any degree of detailed elaboration.

In the report the ease of so powerful tool as QFD-method use for information support of the "marketing-design" interface creating in the tensor CAD database is shown. Also QFD-method is applied in the "economist-executor" interface to quality estimation of the compact manufacture design decision together with a matrix method of enterprise activity efficiency account. The experience of author's researches results application for organisation of compact manufacture of products of instrument making, machine-tool construction and production of wide consumption on a number of the enterprises of Vitebsk region is discussed.

Dr. Dmitry N. Svirsky after graduating from Vitebsk State Technological University in 1984 and post-graduating studentship of Moscow Aviation Institute (1991) had obtained there his doctoral degree with the first in former USSR thesis on technological principals of Rapid Prototyping. After finishing post-doctoral training (1999) in Institute of Engineering Cybernetics (Minsk, Belarus) he is working as associate professor on Machine-building department and science leader of CAD Centre of Vitebsk State Technological University. Dr. Svirsky is Associate Member of International Academy of Information Technologies and President of Belarus National DAAAM Organisation. He has more than 100 publications on Compact manufacturing systems, organisation design, production systems efficiency and 10 inventions on Rapid Production theme.
