Additive mathematical model of gas consumption process

The problem of construction a new mathematical model the gas consumption process is considered in this paper. presented as an additive mixture three components: cyclic random process, trend component and stochastic residue. obtaining components carried out on basis caterpillar method, thus ten singular decomposition. In approach, formed from sum nine schedule, which have one thing common – repeated deployment over time. second decomposition, residue difference between values studied components. Two approaches to processing based known stochastic-periodic models are used Application form with structure makes it possible obtain estimation variance cycle provided segmentation depressions, much less comparison obtained for indicating greater accuracy study will use estimates when modeling further studies.
