Compared with traditional deterministic structural static analysis, it is more practical that strength reliability analyses for bus body frames involving uncertainties in material and in geometrical parameters.
Because bus frame assembles are manufactured of a material with a linear elastic, reliability analysis for bus body frames can be classificatory performed [5].
During the frame reliability analysis, the basic random variable is as follows: (3) where Yj(j=1,2,…,n1) consists of yield stresses S1 of various materials, elastic modulus EX, lumped mass M, density DENS, geometry size of beams l and external loads {P}.

As the theory contents are less in management parameters, their studies are referenced from existing materials and experience, and (they also raise that) these parameters need further proof.

A HTVE-NSS is a human-machine interactive system for the negotiation sides reaching an agreement that it takes the information technology as the method and applies the theory and method of decision science, behavioral science and some related science.
According to the negotiations, it assists all quarters to define the problem, recognize conflict, improve the model, enumerate the feasible agreement with background material, and then it analyzes the situation for the negotiation sides.
Under the certain conditions of the enterprise resource, it’s the second task that how to use time reasonable and human and material resources so that it can propose the most satisfied negotiation agreements.
