The repository has two folders including data for the Generalized tactical resource allocation problem (GTRAP) and multi-dimensional three-objective knapsack problem.
The GTRAP is a model developed for GKN Aerospace AB,Sweden. The instances are made publicly accessible and the names of parts are sanitized. The model is capacitated multi-level resource allocation problem (A criterion space decomposition approach to generalized tri-objective tactical resource allocation. Fotedar, Strömberg et.al). The input parameters required are processing times, qualification costs, upper bounds on inventory, demand. The data shared here consists of Constant data, that is same across all the 15 instances. Instance specific data is stored in GTRAP instances
The instances are taken from M. Mesquita-Cunha, J.R. Figueira and A.P. Barbosa-Póvoa. The data is copied and stored here 3KP Instances. However, we have randomly chosen 10 instances per class for assessment 3KP instances
