Optimal Pollution Control in a Dynamic Multi-echelon Supply Chain / X. Brusset, A. Jebali, D. LA TORRE, S. Mazahir. - In: ENVIRONMENTAL MODELING & ASSESSMENT. - ISSN 1573-2967. - 27:4(2022), pp. 585-598. [10.1007/s10666-022-09824-7]
Abstract:
Today supply chains must internalize the impact of transport on the environment in their cost models. Therefore, managers
must reduce green house gas emissions while striving to increase cost efficiency and satisfy demand. Our multi-echelon sup-
ply chain model minimizes pollution and cost while trying to achieve the best match between supply and demand over time.
Three supply chain network configurations are investigated. Two of them are two-echelon: the first involves several suppliers
and one warehouse, while the second involves one warehouse and several retail stores. The third network configuration is
a three-echelon supply chain including multiple suppliers, one distribution center, and several retail stores. Using optimal
control theory, we derive closed form solutions in such multi-echelon supply chain planning problems with consideration
of pollution. This approach extends in a new direction the literature in operations and transport management by simultane-
ously addressing demand, supply as well as the greenhouse gas emissions that continuously vary in time and location. The
proposed model provides a decision maker with the optimal choice of right deliveries, right times, while minimizing green
house gas emissions. A numerical illustration presents some insights.
