Year: 2018
Type: dissertation
Abstract: This thesis presents supply chain management optimization with meta-heuristics approaches, specifically on issues regarding the configuration of a generic multi stage distribution network, and the determination of a milk-run delivery issue in lean supply chain management. Indeed, this issue can be represented as the routing of the supply or delivery vehicle to construct multiple pick-ups or drop-offs on a regularly scheduled basis and at different locations. \n \nThe optimal model for this milk-run delivery issue must aim to improve vehicle load and minimize transportation distance (optimal delivery route) between facilities while optimizing the entire delivery of goods among the supply chain facilities. The set of meta-heuristics approaches and hybrid meta-heuristics approaches introduced in the present research aim to become a modeling system to find an optimal solution for the transportation distance as well as the optimal delivery frequency for managing the transportation of goods in highly complex logistic networks. In fact, the optimal transportation distance ensures that the total cost of the entire supply chain is minimized. \n \nIn particular, this modeling system groups concepts about integrated supply chain management proposed by logistics experts, operations research practitioners, and strategists. Indeed, it refers to the functional coordination of operations within the firm itself, between the firm and its suppliers as well as between the firm and its customers. It also references the inter-temporal coordination of supply chain decisions as they relate to the firm’s operational, tactical and strategic plans. \n \nThe milk-run delivery issue is studied two ways: with the Genetic Algorithm approach and with the Hybrid of Genetic Algorithm and the Ant Colony Optimization approach. Various frameworks, models, meta-heuristics approaches and hybrid meta-heuristics approaches are introduced and discussed in this thesis. Significant attention is given to a case study from the automobile industry to demonstrate the effectiveness of the proposed approaches. \n \nFinally, the objective of this thesis is to present the Genetic Algorithm approach as well as the Hybrid of Genetic Algorithm with Ant Colony Optimization approach to minimize the total cost in the supply chain. \n \nThis proposed Hybrid of Genetic Algorithm along with the Ant Colony Optimization approach can efficiently and effectively find optimal solutions. The simulation results show that this hybrid approach is slightly better efficient than the genetic algorithm alone for the milk-run delivery issue which allows us to obtain the minimum total automobile industry supply chain cost.
