Over the last few years integration issues in the industry sphere and roles of the end product sales in this process are under active discussions in the scientific sphere. The interest to the problematics is conditioned upon serious competetive recovery reserves of the cooperative producers and the end product consumers. High risks and distrust to the contractors increases transaction expenses which reduce the competetive recovery. In response to the growing integration processes there is a task of intercompany management of economical formations in the industry.

         Let’s work a task. The traditional system approach satisfies the requirements of the economical relations current stage. With that today amid the integration processes development the issues on economical practicability and mutual dependance in the whole chain of the participants cooperation become topical, i.e. development and system approach range expansion including its contragents study. Under the conditions of integration processes development the necessity of range expansion of the system approach to the assesment and integrated subjects management has been proved.

By integration of the industry companies we take a process directed to joining of the economical entities to the entire financial and economic «nature» in order to achieve competitive advantages in the external environment through the efficient additions of the potential participants that form its structure. In other words, by integration we can mean both the process and result of interaction between the separate structural elements of some assembly that leads to the link optimization between them and their union into a single system which has a new quality and new potential possibilities videlicet synergy. This is accompanied by an increase in the effectiveness of the activity due to compound of the separate parts into a single system through the so-called systemic effect. In particular, the integration in a metallurgical complex allows to reduce cross unit costs for the final production, cost savings linked with the outside contractors and intermediaries, transaction cost reduction for the intermediate products indirect taxation. In addition, there is a possibility of capital-intensive projects and research programs. Integrated steel structure profitably differ with a higher stability and lower dependent on adverse changes in market conditions.  

The main division criterion for the integration unions to full, partial and quasi-integration is an active company control extent over an ownership of the companies belonged to the union while maintaining a full control over developing the different business forms. Performance of the quasi-integration economical forms: virtual corporations, strategical alliances, clusters, delivery chains. First two forms define unions in the big business sphere, second two forms appear mostly in the medium business sphere. Economical forms of the quasi-integration: virtual corporations, strategical alliances, clusters, delivery chains. It ought to be remarked that the generally accepted «quasi-integration» definition doesn’t exist. At that different sources core with mismatch of the definitions and the phenimenon conception as well. Particularly, K. Blua defines quasi-integration as a situation where «the companies avoid the vertical integration risk or the ownership rigidity taking out its advantages» [1]. By quasi-integration  M. Dietrich means «permanent relations between legally independent economical units» [2].  V. Tretiak has the same opinion; he thinks that we should link quasi-integration existence with the assets integration  of legal independent companies that voluntary give consent to control over their assets [2].

Quasi-integrated structure is a combination of theindependent companies and organizations that coordinate the activities based on network interaction principle and high trust degree defined by non-formilized relations, sociability, mobility, dynamical structure. Differential peculiarity of the quasi-intergartion stuctures is period of relations that is enough to create some «internal» systems of the norms and rules for the group which in most cases allow not to apply to the «external» third party for conflict management. At that the certain norms are formed - «stoppers» that make each of the partners to consider the interests of other participants and thereby conduce the structure stability. Quasi-integration forms are shown in the table Nr 1.

 General description of the corporate integration forms

Thus , it is advisable to introduce the following industry company organization and management principles under conditions of the integrated processes: using of the same management methods; moving from competition to cooperation with the supply contractors; cooperation with a slimited numbert of reliable product buyers and material resources suppliers; quasi-integration with key customers and suppliers at least of the first level in order to ensure stability and reduce the risk; fast reaction to the order; established mutual payment system for the resources; formation of a single chain costs; inventory optimization for the whole supply chain; tendency for the integrated structure innovative development.

Let us work another task. An author method of supply, production and sales performance optimization at the industry companies under conditions of the integration with contragents has been developed. As distinct from the existing ones first of all it is based on expenses and losses identification sources in the supply chain «supplier-producer-consumer»; secondly it takes into account the correlation between costs and losses; thirdly it shows different schemes of the flow processes with taking into consideration the external environent requirements and interaction with the byuers each of which impacts to the reason and value of the expenses and losses; fourthly it allows to plan the optimal supply and sales parameters based on a difference in  production delivery time and its payment. The criterion is minimum of the integral expenses that includes classic, logistic and transaction expenses [3-5].

Oriented to the proposed method an economic and mathematical model for identifying the supply and sales parameters under conditions of advance payment and delay of payment at the integrated companies based on the modern programs application has been developed and tested at one of the biggest metallurgic compaies in Russia [6]. The model allowed to get the following practical results: minimal value of the integrated expenses could be achieved at the time value of the sold production payment and it is rubles; modeling of the variant with an advance payment for the sold production has shown that the minimal value of the intergated expenses could be achieved at the advance payment value =40% and waiting time of the end production 34 days; best balance between sales rejims could be achieved at the payment time of the sold production 5 days and waiting time of the end production from 17 up to 34 days depends on the advance payment and sales volume on the advance payment; to increase customer service level for 1% it’s required to increase expenses for  1,8 milion rubles, at that losses will be reduced for 0,85 million rubless. Vice versa, service level reduction for 1% will lead to losses increase for 0,9 million rubles, at that expenses will be reduced for 0,3 million rubles [6,7].

Practical relevance of the work is what the obtained results allow to move from an intuitive to the scientific rationale of the management decisions took by a management of the integrated industry companies in the cost control process.

Economical effect lies in expenses reduction by stages of the producer cash flow that at in the stage of quasi-integration with suppliers of the material recources and consumers of the end production [8].

Developments and guidance papers have practical value and could be used by management and specialists of the economical subsidiaries.

Individual contribution of the article writers lies in original optimization method development and building up a model of the effective functioning industry companies integrated into a supply chain.

Conclusions:

- under conditions of growing integrated processes there is an objective task to develop a new management tool and perfom its evaluation; the criterion of the effective management under condition of the integration is minimum of the integration expenses for the whole product promotion chain from formation up to consumption, from the supplier up to end consumer; to take fast management decisions it’s required to build up an adequate model which allows to define and approach optimal parameters of the integrated participants in a real-time mode.
