The article focuses on the problem of jointly control of titanium sponge recovery and magnesium electrolysis stages. Analysis of operational process of segments of electrolysis and reduction of spongy titanium is made; it helps to determine systemic links and to investigate methods of joint control over them. The shortcomings of traditional simulation systems have been stated as applied to this task. A set of C++ classes is created to obtain possibility of designing simulation systems (and, potentially, multi-agent and active systems) of industrial processes that differ in absence of structurally pre-determined links between objects and complex algorithms of action and interaction of objects. Links between objects occur in the course of model developing, so the set can flexibly change. Technically, classes of all model objects are inherited from one base class, which allows to properly arrange their calling from a simulated time step function. Modelling time step is achieved by Δ t method, i.e. when special states are accounted after termination of a certain time segment. A unified time step function is cyclically going over all objects, until their state stops changing. Depth of inquiry is set a-priori. A check of created modeling tool made by solving a task with the known solution has been made. A model of elementary queuing system cell based on the class set has been developed. Comparison of the simulation results with results of a similar cell in GPSS. The correspondence of simulation results is shown. The problem of the necessary inquiry depth of objects using time step function has been investigated.
