Economic and environmental considerations in a stochastic inventory control model with order splitting under different delivery schedules among suppliers

摘要: Abstract This study analyzes an integrated inventory control and delivery scheduling problem in a stochastic demand environment with economic environmental considerations. In particular, we examine bi-objective continuous review model order splitting among multiple suppliers, where both expected costs carbon emissions per unit time are minimized. For this problem, two different policies considered for the split orders: sequential delivery. First, formulate under each policy as mixed-integer nonlinear models. Then, adaptive ϵ -constraint algorithm evolutionary search proposed to approximate Pareto front of these A numerical is conducted compare approximation algorithms. Another demonstrates effects variance on policy. Finally, examples presented show how tools provided can be used policies. Our results that supplier selection have strong performance, also good crucial accurately
