The consumption of workshop 50 is determined by the weight of the arc 50-A, the consumption of workshop 51 is determined by the weight of the arc 51-A, the consumption of workshop 52 is determined by the weight of the arc 52-A. The weight of the arc 50, 51 determines the flow of electricity from 1 workshop 50 or the structural unit of the enterprise to workshop 51. If the flow of electrical energy comes from the first workshop or structural unit to the second, then for the first workshop this corresponds to a decrease in power consumption, if the flow of electricity comes from the second workshop first, this corresponds to an increase in the power consumption of the first workshop. The weight of the arc 50-52 determines the flow of electricity from the first workshop to the third. The weight of the arc 51-52 determines the flow of electricity from the second workshop to the third. Mathematically, the process of accounting for energy consumption can be represented in the form of a matrix of the following form:

where a is ₁₁ electricity consumption in the first workshop;
and ₁₂ power flows from the first workshop to the second;
and ₁₃ power flows from the first workshop to the third;
and ₂₁ power flows from the second workshop to the first;
and ₂₂ electricity consumption in the second workshop;
₂₃ power flows from the second workshop to the third;
and ₃₁ power flows from the third workshop to the first;
₃₂ electricity flows from the third workshop to the second;
and ₃₃ electricity consumption by the third workshop.

Electricity consumption is determined by the main counting modules, and electricity flows by additional counting modules. The total consumption of the workshop, taking into account electricity flows, is determined by the sum of the values of the elements of this row of the matrix. Since the elements of the matrix a ₁₃ and a ₃₁ , ₂₃ and a ₃₂ , a ₂₁ and a ₁₂ are equal in magnitude and are different in sign in pairs, it is sufficient to have the values a ₁₂ , a ₁₃ , a ₂₃ .

 To account for power flows between workshops, the values of the main counting modules 3, 4, 5 are entered in the adders 33, 34, 35, respectively. The totalized value of the additional counting modules 10 and 11 is also entered into the adder 33. The value of the additional counting module 15 and the inverse value of the additional counting module 10 are entered non-inverted to the adder 34. The inverse value of the additional counting modules 14 and 15 is entered into the adder 35. The sum of the adders is recorded . Further, this information is read and displayed on the information display unit 32. Thus, on the information display unit, the value of the power consumed by each workshop, unit taking into account the power flows between units is obtained.
