Abstract
In this paper, a bi-level mathematical formulation for a pricing-inventoryrouting
problem in the context of sustainable closed-loop supply chains is
developed. The two levels are entitled as the upper level model and the lower
level model. The upper level model (the leader model) tries to minimize
greenhouse gas (GHG) emissions while the lower level model (the follower
model) focuses on profit maximization. To solve the problem, an enumeration
heuristic method based on knapsack problem and genetic algorithm (GA) is
devised. The results show that the heuristic method is capable of obtaining
high-quality solutions in reasonable CPU-times.
