This type of problems can be found not only in applied mathematics and operational research but also in engineering, economics, politics, transportation science, and so forth. VO contains various kinds of important optimization and variational models with vector-valued or set-valued maps, such as multiobjective optimization, vector variational inequalities, vector complementarity problems, generalized Ky Fan inequalities, vector network equilibrium problems and so on. Some researches show that the Image Space Analysis (ISA) is always a powerful tool to solve nonconvex and nonsmooth optimization problems, and also a unifying scheme for any kind of problems that can be expressed under the form of the impossibility of a parametric system. It is also shown that VO and ISA have the evident potential to remain important and active research topics in both the near and foreseeable future. However, there are few concerns about the open problems of VO and the analytical tool ISA up to now. This special issue concentrates on reviewing the latest progress of VO and ISA and exploring profound open problems to extend the theoretical depth in these areas.
