An order relation, defined by Ishibuchi and Tanaka for maximization problems, is used to obtain the solution of the problems. A real-life example, related to investment, and its solution are given. Necessary and sufficient optimality criteria including weak and strongly solution for interval programming problems are introduced via basic calculus rule, scalarization, and vectorization.eninfo:eu-repo/semantics/closedAccessInterval programming problemScalarizationVectorizationOptimality criteriaArticle10.1007/s40840-020-01012-82-s2.0-8509102377714003Q2138744WOS:000569285200001Q1
