ABSTRACT
According to the positions of international standards of ISO of series 9000 every process must be estimated. It is very important for managing and improving the processes.The aim of the article is the development of indexes of estimating the management process of the streams of raw materials at coke-chemical enterprises.In the production of coke-chemical products a technological process has continuous character and clearly set rhythm. It is impossible to stop it without considerable losses, and the change of rhythm of the process is accompanied by negative influence on the state of laying basic aggregates – coke stoves. Therefore, the question of increasing the level of controllability of the process when providing the enterprise with raw materials coal concentrates for coke-chemical enterprises is the quarantee of effective functioning of the enterprise.The offered system of indexes supposes the establishment of passing ahead and late indexes. As passing ahead the level of residues of coal concentrates is offered at the end of every shift the coal preparing workshop. The necessary level of their supply guarantees the realization of technological process in the set rhythm.As the capacity of indexes that are late serve a coefficient of rhythm of the hourly average gas stream during a day for a month and a coefficient of stability of temperature condition of the coking process for a month. The choice of indexes is explained, firstly, by the fact, that in the process of coking coal concentrates accompanied products are produced – coke gas that is used practically at all stages of technological process and is vitally necessary; secondly, by stability of temperature condition of coking (that depends on stability of supplying with raw materials) which is the guarantee of effective functioning of an enterprise.
