This paper presents a normative balance mathematical model of regional economy that contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. A method for estimation of the model parameters by application of parallel computations on multi-processors systems is presented. It is determined the unknown parameters of economic model by indirect way, comparing time series for macro indexes calculated by model with statistical time series for these indexes. Use of the method is illustrated by the parameter estimation of a macroeconomic regional model by statistical data of Vyatka Region of Russia. The each production sector shadow money stock grows due to sale of shadow final product to households and as intermediate product to other sectors. Identified model is used for estimation of the Regional Government economic politics.

  Capacity Reservation,

  Option Contract,

  Supplier Selection

A key issue for manufacturing firms is planning for outsourced components. In this research, we have considered a manufacturer in a Make-to-Order production environment who has to outsource a special component from a set of suppliers. One selling season is considered and the manufacturer faces uncertain demand during the selling season. A good strategy for the manufacturer to balance both holding and lost sale costs is to initiate capacity reservation contracts with his suppliers. Thus, unlike the previous researches we have presented a mathematical model based on option mechanism that will help the manufacturer to select appropriate suppliers and order allocation, simultaneously. The considered option mechanism has a two part contract fee structure (option price and exercise price) and it is at the foundation of practical contracts used by different industries. A numerical example is used to illustrate the model and to investigate how option mechanism improves manufacturer's expected profit in comparison with the situation without applying the option mechanism .
