The functions of a cell controller are logically decomposed into three groups. These groups are: 1) factory level planning, 2) cell level planning, 3) cell level control.

Factory level planning. The interface modules in the cell controller request or accept input from CAD and business subsystem to trigger (запускать) functions in this group. It is noted that the functions in this group are not performed by an individual cell controller in isolation. This requires departing (отступление) from standard centralized formulation of the factory level planning functions.

Cell level planning. In this group a major task is to maintain status (состояние) information of the respective cell by acquiring real time information from cell interface modules (модуль всех ячеек). On the basis of strategic decision made by the previous level, the cell level planning functions are carried out. These functions require relatively less cooperation from other cell controllers.

Cell level control. This group of functions is for real time control of activities of machines within the cell. The various tasks include preparing processing steps, allocation of resources, monitoring of activities and reporting of status information.

The model presented by us is essentially a distributed real-time processing system with heterogeneous components. Realization of the above system imposes (налагать) special requirements on the software technology: distributed programming, distributed data bases, real-time programming. We have designed a distributed object oriented programming language. Its basic implementation is nearing completion (близок к завершению).
