The tasks proposed for research are optimal control problems with mixed constraints with free-final-time and moving right end. We analytically solve the rapid-action problem. The central mathematical apparatus is Pontryagin maximum principle in Arrow form, using Lagrange multipliers. The theoretically obtained results of the analysis are of particular interest.<\/jats:p>","DOI":"10.1515\/comp-2020-0224","type":"journal-article","created":{"date-parts":[[2021,5,27]],"date-time":"2021-05-27T22:13:14Z","timestamp":1622153594000},"page":"355-364","source":"Crossref","is-referenced-by-count":3,"title":["Theoretical Estimate of the Total Shelf Length in a Gas Fields Model"],"prefix":"10.1515","volume":"11","author":[{"given":"Alexander K.","family":"Skiba","sequence":"first","affiliation":[{"name":"Federal Research Center \u201cComputer Science and Control\u201d of Russian Academy of Sciences FRC CSC RAS Moscow , Russian Federation"}]},{"given":"Nadezhda K.","family":"Skiba","sequence":"additional","affiliation":[{"name":"Kuban State Technological University , Ministry of Science and Higher Education , KubSTU , Krasnodar , Russian Federation"}]}],"member":"374","published-online":{"date-parts":[[2021,5,27]]},"reference":[{"key":"2022020121510220328_j_comp-2020-0224_ref_001","unstructured":"Vyakhirev R.I., Korotaev Y.P., Kabanov N.I., Theory and experience of gas recovery, Nedra, Moscow, 1998 (in Russian)"},{"key":"2022020121510220328_j_comp-2020-0224_ref_002","unstructured":"OPEC.
