Informational Technology as Scientific Branch of Science

It's considered the problem of informational technology formation as the independent scientific branch of science concerning methods and means of creation of higheffective informational technologies (in the restricted sense of this term). They are determined the distinctive indications of higheffective technologies and the main principles of informational resources concentration in space and time as the most important principles of creation of the effective informational technologies are considered.

Interactive Modeling Dimensional of Changes of Preparation at Designing Technological Process Machining

The computer modeling dimensional of changes of preparation on a design stage of technological process is discussed. The way of the program analysis created in AutoCAD of primary model of a detail is offered with the purpose of the automated formation of secondary model dimensional of changes transmitted then to the module dimensional of accounts CAPP. As a means of preparation of secondary model the module in language AutoLISP is used. The illustrations of the basic stages of program realization of an interactive environment in AutoCAD2OOO are resulted.

Vector Optimization Technical System Under Fuzzy Conditions

Problem of optimization of difficult technical system on to vector criterion, given in a fuzzy of kind is considered. The problem is reduced to construction ordered ensembles (subset) Pareto. A method of the decision based on complex application of the theory of acceptance of the decision, fuzzy of sets, interval analysis and method of branches and borders is offered.

Mathematical Modelling of a Conveyor System of Administration Managerialcontrol Supposed Providing Fulfilment of Data Fixed

The formalized exposition of deriving of the effective schedule of work realization for a conveyor type system as a linear integer programming task is suggested. The singularity of the task is great dimensional and account of various moments of requests inflow and fixed data. To solve the task it is suggested that should define a dual task and solve it by means of sub-gradient procedure.

Optimum Control of Manufacturing- and-Selling System

It's suggested the mathematical model of control by firm. The square-low criterion of efficiency of functioning reflecting total losses of firm is stated. It's constructed the optimal control by firm in the form of law with feedback providing the operating control in conditions of demand change. If developed the algorithmic and software bang the basis for construction of the automated control system by manufacturing-and-selling activity of the enterprise.

Transport Protocols Algorithms and Their Influence on Network Performance

The paper describes the analysis of main transport protocols of TCP/IP suite: User / Datagram Protocol (UDP) and Transmission Control Protocol (TCP). It shows their main characteristics, advantages and disadvantages. The topics covered include the algorithm of virtual channel establishment and congestion avoidance techniques. The effectiveness of two TCP-versions TCP Pseudo-Rate and TCP-NewReno has been shown by comparing them with other transport protocols, like TCP-Tahoe and TCP- Reno.

Computer Technology on the Base of Modular Algebra

In the paper it is shown a possibility of creating an efficient computer technology based on-using number and polynomial theory. In particular, it is introduced a mixed number system that possesses dignities of a position number system with a large radix and a remainder system with a small number of moduli having small values. Besides, special polynomial transforms, also represented in the paper, can provide additional essential speeding up of computer processing 6'f numerical data including polynomials.

Mathematical Modeling and Stochastic Temporary Characteristics Research of Computer Data Processing.

The paper discusses a possibility for mathematical formalization of the global algorithm for computer processing arid its description by ordered state graph. This is used for an analytical modeling of computational processes and some deterministic and stochastic characteristics defining. A program environment (by APL2 language), for automation of its investigation is realized. The results of program experiments for deterministic transformation of graph model and some Stochastic characteristics Investigation are presented.
