A Multi-objective Model for Location-Allocation Problem with Environmental Considerations
The paper presents a multi-objective model for solving location-allocation problem (LAP) which considers the greenhouse gas. It involves the determination of the best strategy to distribute the product in a distribution network by selecting proper locations of plants and distribution centers as well as the allocation of products from plants to warehouses and from warehouses to customers. Two objective functions are considered simultaneously. The first objective is to minimize the total logistics costs and the second objective is to minimize the total amount of greenhouse gases generated by the activities. The model is validated using the test data that were derived from published benchmark test data set. The mathematical model was solved using CPLEX by converting one objective into a constraint with slack. The set of trade-off solutions is generated by solving the model repeatedly with varying slack values.
