Figures & data
Figure 1. Set-up of working environment with three human workers and one robot.
Figure 2. Matheuristic approach.
Table 1. Comparison between the heuristic (H) and the ILP model for the single board problem. Averages are taken over 10 instances.
Table 2. Comparison of the different sorting strategies in the heuristic approach for the multiple boards problem (deviation in ).
Table 3. Average idle times for the heuristic and matheuristic approach (in time units). Averages are taken over all instances and over all heuristic approaches.
Figure 3. Comparison of the different presorting strategies over all 10 instances.
Table 4. Average deviation of each matheuristic strategy to the best matheuristic strategy in and the number of instances (
) in which each strategy found the best solution out of all strategies.
