This is the data consisting of instances used in the experiment on the research of Iterated Variable Neighborhood Search for integrated scheduling of additive manufacturing and multi-trip vehicle routing problem. The data is used to test the performance of the aforementioned algorithm to solve the aforementioned problem. The experiment instances are classified into small-scale problems and large-scale problems, which are differentiated by the size of the fixed problem parameters when generating the instances. In addition, the instances used for the sensitivity analysis experiment are also included. The number in the instance file name indicates the instance sequence with respect to the table result presented in the aforementioned research. The instances data are generated stochastically inspired by the real data of the aviation industry with a slight adjustment using Python Programming Language.
