Group scheduling with deterioration and exponential learning effect processing times

In this paper, we introduce scheduling problems with time-dependent linear deteriorating jobs and position-dependent exponential learning effects under group technology. In our model, the group setup times are linear functions of their starting times and there is linear deterioration and exponential learning effect with processing time of jobs. We show that the problems to minimize the makespan and the sum of completion times remain solvable in polynomial, respectively.
