3.3. Conceptual positions of working out of model of investment activity of natural monopoly

Search of the decision for the organizer of the investment project of the enterprise I eat also definition of specifications of regulation of investment activity for the state it is possible to carry out with the help economic - mathematical models.
The problem investigated by us has three prominent features which are necessary for considering in the course of modelling: plurality of participants of management of investments, plurality of the problems decided within the limits of investment activity, and the uncertainty of decisions connected with ambiguity of the initial information. Thus it is necessary to consider, that on structure and the importance of the revealed aspects of a problem in the course of its decision considerable significance renders type I eat.
The general statement of the problem connected with investment activity I eat, following. It is necessary so to plan investments (directions, volumes and terms), their financing and works on realisation that the discounted effect received as a result, whenever possible, to the greatest degree satisfied to interests of all participating in management of investments of subjects at restrictions on the prices, production volumes I eat, and also restrictions of financial and other possibilities, with allowance for ambiguity of the information on receipts, expenses (material and time), connected with investments.
Mathematical problem definition of a choice of directions of investment activity I eat will be following. Among set of X admissible variants (directions) of investment activity I eat to choose those HO, which joint realisation supplies the best joint satisfaction of the purposes of all subjects (I eat, the states, managers, an aktsione-ditch, other men of weight), making of the decision in the given area, at restrictions on:
Financing possibilities - F1;
Capacities of the resources used in the course of realisation of investments (own and involved) - F2;
Minimum level of maintenance of consumers with production I eat -
F3;
Others important for company activity parametres I eat - F4.
Restriction F2 can be lowered if to accept, that access to
Required for realisation of investments to resources it is not limited and it is defined only by financial possibilities of their consumption.
The given statement is the general as it can be applied at a choice of different degree obobshchennosti directions of investments: spheres of activity in some direction, objects of investment for the given area, the concrete project of realisation of the chosen object. The problem can be decided consistently for all levels of hierarchy of directions of investments.
The required decision represents a vector defining structure of realisation of variants of investments from set of the admissible. It is supposed, that the same variant of investments cannot be realised repeatedly. Significance of variable model Xj represents a share of a total cost of realisation i-ro an investment variant (h, = [0; 1]) at the assumption of infinite divisibility of investment objects. In that case when the variant can be realised discrete parts (in some slu -
Teas or completely, or it is not realised absolutely not), a model variable can accept certain discrete significances (for example, 0 or 1). In a general view financial restrictions the following:
fjKu-xi t - capacity j-ro a production factor in t-й an interval. Restriction on socially necessary volume of production F3 takes place for I eat, manufacturing production of strategic appointment, and also for the large adjustable enterprises I eat. An exception make I eat in the markets with a potential competitiveness.
Additional restrictions can be entered into model. They represent state requests to ecological and to other kinds of safety of investments, social aspects of activity I eat.
Besides, the additional restrictions caused by mutual relations between investment objects can be entered.
In case of interdependence of investment objects Xj+Xj< 1 (при целочисленности значений Xj, Xj = 1 или xj, Xj= 0), причем i ^j (ij = 1,2,..., N).
В a case of complementarity of investment objects
Xi - Xj < 0 (при целочисленности значений хь Xj = 1 или Xi, Xj = 0).
Mathematical model for a problem of a choice of directions of investments in a general view following:
