A representation condition for one order discrete closed-loop fuzzy systems is proposed, By using the method of linguistic relation matrix, the stability of high order discrete fuzzy systems is discussed.

Deduces the fuzzy relation matrixes from the definitions of the membership functions in various states.

On the basis of the above definitions,we construct an undirected graph model for product family architecture and its customization constraint relation matrix.

The relationship matrix between user requirements and technological characteristics determined by designers in the quality room reflected objectively the degree of importance of user s requirements to a certain extent.

With "capacity, safety, productivity and investment" as feature targets, and according to three different levels of hump automation, the author constructs the fuzzy relationship matrix,finds the fuzzy subset, and according to which, makes comprehensive evaluation with figures.

Approach for embedded components reduction based on relational matrix

This article proposes the direct algorithm and the impovement algorithm to strive for the periodicity of relational matrix.

HOQ is the core of the principle of QFD and consists of clients demand, quality factors, relational matrix, correlation matrix, evaluation of client rivalrousness and te.

But it can become more easily through matrix of relation.

After observing the characteristics of the matrix elements and deeply researching Warshall\'s algorithm,three discriminances of determining the transitivity of binary relation with the matrix of relation are obtained:sum logic,logic multiplication caparison and painting rounds and forks.
