The apriori and aposteriori H〓-optimal filtering question can be solved directly. L〓 Apriori and aposteriori filtering with an H〓 error bound can be solved by semidefinite programming.

In chapter three, with the effective combination of the prior preference, posterior preference and interactive method, and based on the theory of satisficing decision making and goal programming, an interactive method for solving static or dynamic multicriteria programming is devised. In the method, by constructing the simplexes in the set of parameters and transforming them, the local preference information is interactively quested in th process of decision making. The prior and posterior preference are used to speed up the process of decision making and overcome the false convergency which may be occured in pure interactive algorithms. This method can be used to cope with linear, nonlinear and dynamic multicritcria programming.

The modular design of printNet system is divided into several application part, such as data processing tools, design tools, products, Business card printing tools, and solutions to technical tools, of which the highest is a design tool over the actions that it printLayout from page formatting and setting variables, but also can be used by an operator in a transform tool programming, so that the contents of the variables in a database in output for operations, now produetion of mostly to one-dimensional bar codes and encrypted bit or anti-false, the party is a method in the bar code by addition, subtraction, multiplication, Division, opinins Mo, and so after the results or the results of data, or the result is converted to the data that corresponds to a location in one of the ntehs detection accuracy is valid, just make a bit of the inverse operation, the operation that results in comparison with the original data, such as the same as the data is valid, such as different then the data is not valid, this scenario is the most simple and most primitive anti-counterfeit. PrintNet software to complex product environment " interpuntion and output the integration of integrated management " solution possible.
