This paper has done a deeply research on the evaluative method, which focus on maintaining and ensuring the camion. After deeply analyzing the maintain theory of army equipment and the stratagem 's characteristic and combining the current systems engineering evaluating theories and methods, it has analyzed and solved all limitations that coming forth when a single model is used to evaluate the maintain capacity. After analyzing and ameliorating the judgment of AHP's coherence, the calculation of the expert power value and the optimizing of the more-extreme judging model, a new calculation method, the multidimensional complex calculation theory, is presented, which much fits for the evaluative calculation of the camion. The new theory's feasibility and the evaluation's reliability have been proved in theory in this paper. This paper also analyses the principle and the program, which is about building a camion evaluating system. According to the multidimensional complex calculation theory, an evaluative model has been built. Applying the levels analytical method, this paper fixes on the calculation of every target's power, brings the optimization allot precept of macro spatial resource, optimizes the resource of the maintainability of theater of operations' vehicle, which offers a theory foundation for optimizing of the resource space. The research not only brings out a uniform standard for the evaluating of the maintain ability of the camion, but also presents a theory foundation and method for perfecting the camion maintain system.
