Embodiment Construction

[0034] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0035] In product design activities, design decisions are ultimately reflected by parameters, while design constraints are manifested as parameter dependencies. By analyzing the applicable conditions of different dependencies, the parameter dependencies can be accurately expressed by using a finite state machine, and then generated by a finite state. The parameters of the machine representation depend on the model. Parameter dependency models mainly include two types of elements: parameters and mathematical dependencies between parameters. The finite state machine is a mathematical model that represents a finite number of states and behaviors such as transitions and actions between these states. The present invention expresses the mathematical dependencies between parameters as states, and expresses the ...

Abstract

The invention belongs to the technical field of product design, and discloses a method for generating a parameter dependent model based on finite-state machines. The method includes the following steps that 1, according to the parameters and design constraints of a product system, corresponding parameter dependent relational expressions are listed and added in a parameter dependent relation set; the corresponding finite-state machine and the state of the corresponding finite-state machine are set for each parameter dependent relational expression in the parameter dependent relation set, and conversion conditions are set for the states of finite-state machine models; 3, each parameter of the product system is associated with the output parameter and input parameter of the corresponding finite-state machine, and a parameter dependent model of the product system is built. The method effectively eliminates possible human errors caused by artificial modification of the parameter dependent model, shortens the design cycle and improve the design efficiency.

Description

technical field [0001] The invention belongs to the technical field of product design, and in particular relates to a method for generating a parameter-dependent model based on a finite state machine. Background technique [0002] Product design parameters are the ultimate embodiment of various design decisions, and are also the basis for determining whether various design requirements of a product can be met. In the process of product design, there are a large number of constraint dependencies, and these dependencies are finally represented by parameter dependencies. The parameter dependency model plays an important auxiliary role in propagating design changes and supporting multi-domain collaborative design. [0003] Existing parameter dependency models only contain static parameter dependencies, and the dependencies between parameters are fixed. However, design changes may lead to changes in parameter dependence. In order to maintain the consistency of the parameter depe...
