Technical field:
The invention belongs to mechanical design field, relate to a kind of Formal Design Method of anticorrosion pipeline, particularly a kind of Formal Design Method towards anticorrosion pipeline based on polychromatic sets.
Background technology:
(1) product should take into full account user's request in the early stage design phase, and it is decomposed, just can obtain some feasible methods for designing, need to set up effectively scheme evaluation and an Optimized model this moment, all feasible schemes are estimated, finally selected optimal case.Set up hierarchical model and be the committed step in the formal design, identical mathematical model is come the different object of emulation on the polychromatic sets type of service, so that analogue system has flexibility more, established theoretical foundation thereby process automated system for the unified information of setting up Product Life Cycle Design.
Polychromatic sets can show the shown character that does not go out of ordinary set.The traditional set of all usefulness of for example, establishing element can be expressed as:
A=(a
1,...,a
i,...,a
n)
From in form, although these elements are different, with the mode that represents of this kind tradition set, to show different only be their name.Their any other character all can not show in form with the mode of tradition set.In any case these character are used the mode that manifests in the ordinary set theory be also can not represent out.Polychromatic sets is a kind of new information processing instrument.Its element and integral body itself can both be coated with some different colors simultaneously, are used for representing the character of research object and its element.
For the elements A in the polychromatic sets=(a
1..., a
i..., a
n), color set F (a
i) corresponding each element a
i, a wherein

Wherein F (A) and F (ai) are called as painted.
When the form with polychromatic sets represents simulation object, certain property of object and element, corresponding with the color F (ai) of the color F (A) of object and element ai.
Circuit: the circuit concept is the abstract of technological concepts such as character, attribute, parameter, feature and index and summarizes.At employing multicolor set and polychrome figure to the complicated production system or when carrying out the emulation such as mechanical product information, custom use " circuit " this concept, and inapplicable " color " this term.
The individual is painted: F (A) and F (ai) are called as painted, and wherein, the color set F (ai) that belongs to element itself is called as the individual painted of this element.The individual painted of polychromatic sets all elements can represent with Boolean matrix:
Wherein, if exist
F
j∈F(a
i)
And
Then
C
i(j)=1
It is as follows that color Fj is expressed as logical variable:
The individual painted F (ai) of element ai determines by the composition of the i row element Ci (j) in the following formula, namely as Ci (j) when getting 1, has restriction relation between ai and the Fj; As Ci (j) when getting 0, there is not constraint between ai and the Fj.Its formalization representation is as follows:
Unified painted: for the individual color Fj (ai) with element ai ∈ A distinguishes, be called as unified color as the color Fj (A) of the polychromatic sets integral body of same target, all compositions of these colors are called as unified painted.
Wherein, if exist
F
j(A)∈F(A)
And
Then
E
i(j)=1
The individual painted F (ai) of element ai determines by the composition of the i row element Ei (j) in the following formula, namely as Ei (j) when getting 1, has restriction relation between ai and the F (ai); As Ei (j) when getting 0, there is not constraint between ai and the F (ai).Its formalization representation is as follows:
