Proper parameters play a decisive role for the optimization. In the opinion of writer, availability is a basic parameter, failure consequence cost and failure characteristic are also important parameters. Maintenance strategy can be optimized on the base by means of quantitative analysis and diagram. 展开更多

This essay tries tO explore the contemporary significance of Marx's economic theory of the motivation and the behavioral model of the agents of capitalist production. The first and the second part of this essay review and analyze the concept of the agent of capitalist production in Marx's theory, and point out that Marx explains the motivation and behavior of the agents of capitalist production from the perspectives of capital in general, competition, and uncertainty respectively. The third part of this essay offers a brief comment on the interactive relationship between the institutional varieties of capitalism and behavioral model of the agents and points out that the concept of the agents of capitalist production has its inherent limitations when confi'onted with the problem of institutional varieties. 展开更多
