Influencing factors reduction plays an important role in ship maintenance cost forecasting. Recently, the grey correlativity analysis method is often used to deal with the problem. But the reducts by this method is not satisfied. In this paper, we attempt to use fuzzy rough set theory to solve the problem. Under the framework of fuzzy rough set theory, the definitions of fuzzy equivalence relation,...
Scientific forecast is of great importance to the economic phenomenon research and economic decision-making. Therefore, the research about economic forecast theory and method is always a hot topic. This paper proposed an algorithm combined with the grey model, least square method and topology model, which can be a new advanced algorithm for forecasting. Using this new algorithm, the paper forecasts...
The system structure and operation process of the minimally invasive surgery robot based on vision location technology are expounded. The three- dimensional location problem of robotpsilas hand-eyes vision system is lucubrated, whose core idea is directly putting the image coordinate mapped into the robotpsilas radical coordinate and getting the system parameter as a whole and not separately calculating...
