Celem pracy jest autorskie opracowanie metodologii planowania międzybranżowego, związanej z wykorzystaniem ekonomiczno-matematycznego modelu W. Leontjewa i bilansów międzybranżowych typu „wejście– wyjście” [1, 2]. Opracowany został nowy typ bilansów międzybranżowych (BMB „P-P”) i algorytm ich optymalizacji, imitujący mechanizm regulacji rynkowej z uwzględnieniem różnych warunków popytu na produkcję...
The economic-mathematical model of the sustainability and predictability of the transportation system and the sea ports was considered as a single model encompassing those related to the financial sustainability and predictability of the enterprises. The author substantiated the expediency of creating the models by way of the logical probability simulation. 10 indexes were suggested for the evaluation...
The article presents the findings of the use of adaptive models in forecasting a variable with seasonal fluctuations. To this end the following models were used: triparametric Holt-Winters models for original data (with seasonality) and biparametric Holt models for data free from seasonality for series of different length. During the ex post analysis of the forecast accuracy, an attempt to determine...
