Firstly, a non-linear programming mathematical model is constructed for the regional hub-and-spoke RRCT network based on uncertain cost-time-demand. Then, an improved genetic algorithm is designed to obtain an optimized scheme. The algorithm uses genetic algorithm to search the global space, and uses two local search methods, i.e. shift and exchange, to search the local space. Finally, the RRCT network along the Yaan-Linzhi section of the Sichuan-Tibet Railway is used as the research object to verify the applicability and effectiveness of the regional hub-and-spoke RRCT network model and the algorithm proposed in the study.<\/jats:p>","DOI":"10.3233\/jifs-200748","type":"journal-article","created":{"date-parts":[[2020,9,8]],"date-time":"2020-09-08T10:59:08Z","timestamp":1599562748000},"page":"7293-7313","source":"Crossref","is-referenced-by-count":3,"title":["Modeling
