This article examines an issue of system aspects and investment features in IT sphere, state of IT market and its progress trend. An analysis of the types and investment features in IT, investment evaluation methods was implemented. Objectives tree was developed. A general algorithm structure for evaluating investment in IT branch was proposed.
The grounding task of identification the flagrant error limits of measurings is decided in height geodesic networks at their search by the analysis of misclosures in grounds. Certainly critical intervals of rough errors identification in a ground depending on the amount of the stations and measurement errors in it.
For the specified ski courses relief research the algorithm and then the program ‘Course Calculation’ were developed. On the basis of the two-dimensional terrain image it is possible to design the arbitrary amount of ski courses profiles variants. The basic parameters
of the ski course relief are determined and also compared to the normative values
The constrained optimization task of wool sheepskin tanning–greasing applying the gradient method is solved. The optimality criterion is formulated as a generalized additive objective function. The modified gradient method algorithm is based on software module. Mathematical description for a low-waste technology using dry chrome tanning agent is obtained and its constraints are determined.
