  1. Aksioomidest lähtuv projekteerimineAxiomatic Design Lembit Roosimölder

  2. Aksioomidel põhinev konstrueerimine (MIT)

  3. General Axiomatic Design Concepts • Understand their customers' needs • Define the problem they must solve to satisfy these needs • Create and select a solution • Analyze and optimize the proposed solution • Check the resulting design against the customers' needs

  5. Axiomatic Design The output of each domain evolves from abstract concepts to detailed information in a top-down or hierarchical manner Valdkondade väljundid arenevad abstraktsetest ideedest kuni üksikasjaliste kirjeldusteni Two design axioms provide a rational basis for evaluation of proposed solution alternatives and the subsequent selection of the best alternative Kaks järgnevat konstrueerimise aktsioomi on ratsionaalseks aluseks lahendusvariantide hindamiseks ja valikuks The first axiom is the independent axiom, and it states that a good design maintains the independence of the functional requirements Esimene, sõltumatuse aktsioom ütleb, et lahend on hea vaid siis, kui on tagatud funktsionaalsusnõuete sõltumatus The second axiom is the information axiom and it establishes information content as a relative measure for evaluating and comparing alternative solutions that satisfy the independence axiom Teine, informatsiooni aktsioom ütleb, et info sisu peab tagama selliste lahendusvariantide võrdlemise ja hindamise, mis vastavad esimesele aktsioomile.

  6. Axiomatic Design • With QFD (Quality Function Deployment, "the voice of the customer"), designers gather information from customers about their requirements and the relative importance of each. This information helps the designer to choose which FRs must be present and which may be safely ignored. • When a designer has selected an FR and wants to identify alternative DPs to achieve it, TRIZ (the theory of inventive problem solving) can be helpful in generating alternatives. • After choosing a DP to satisfy an FR, the designer uses robust design to optimize the design of this particular DP, which helps to reduce the information content of the design. • The designer follows the axiomatic design process and uses the various techniques when appropriate. Axiomatic design helps the designer avoid mistakes such as unknowingly attempting to optimize a coupled design.
