“…Regions watch and follow external environment for identifying and making use of its favourable opportunities, while avoiding threats and obstacles at the same time (Kuznetsova, 2016a;Leksin & Porfiryev, 2016a). This is possible due to the study of the nature and dynamics of changes happening in the external environment (Leksin & Porfiryev, 2016b;Naumov & Petrovskaya, 2010a;Naumov & Petrovskaya, 2010b) together with drawing up a list of opportunities and threats that in future will open the way to both: using of favourable opportunities and finding effective responses to the challenges of the environment (Ivanter et al, 2018;Novikov & Belov, 2019a;Novikov, 2019b). This process is called monitoring of multidirectional data of the external environment of the regional socio-economic system (hereinafter RSES), which implementation becomes possible through decision-making support system tool kit "DATA" (hereinafter DSS "DATE").…”
