A (P_relative). – relative consumption. The proposed load;

A_loss (t₁, t₂) – the difference between the incoming supply of goods and serviced supplies of goods;

A_inc. (t₁, t₂) – incoming supply of goods over a period of time (t₁, t₂);

A_served. (t₁, t₂) – the sum of the quantities of goods handled by consumer group during the period (t₁, t₂₎.;

A _TGD. – the demand value for time of greatest demand;

A_obs. – the demand value during the observation;

a – the load intensity coming from a single source;

c‘_receiv s the number of received requests;

c‘_serv – the number of serviced requests;

c‘_lost. – the number of lost requests;

c‘– average length of queue or average numbers delays batches of goods;

P_max– maximum consumption;

P _goods. – losses of volume of goods;

P _request. – losses in the number of requests for suggestion of goods;

P _goods. – losses of volume of goods;

P t- losses of implementation time;

p (γ> 0) the probability that the waiting time is greater than zero – that is, the probability of queue;

p (γ> t) – the probability of waiting for any incoming product over time t;

p (R> r) – the probability that the queue length exceeds the specified value r);

(γ) – the average waiting time in relation all requests received;

γ _delay the average waiting time of only a delayed requests;

Λ (t₁, t₂) -the mathematical expectation of the number of supplies placed on the market in the time interval [t₁, t₂);

μ (t₁.t₂). – the instantaneous flow rate;
