Distribution network design: New problems and related models

“…According to the Ambrosino and Scutella, (2005), while analyzing a distribution network, two factors can be distinguished such as the optimization of the flows of goods: in this case it is considered an existing distribution network, and need to optimize the flows of goods through the network; and the improvement of the existing network: in this case need to choose the best configuration of the facilities in the network in order to satisfy the goals of the company, while minimizing the overall costs. There are extensive literatures available on the analysis of supply chain coordination.…”

Abstract:The study focuses on using optimization and simulation-based modeling approaches to evaluate the performance to assess the viability of a Supply Chain Network Design (SCND). It enables companies to perform powerful what-if analyses leading them to make better informed decisions. The study helps companies evaluate the appropriate number, location and necessary capacities of their distribution centres (DCs) and warehouses based on projected demand and service level targets. This allows the decision makers to see the performance of the supply chain over time under various scenarios and assist them to understand the inter-relationships between different modeling components. The authors have using retail supply chains as a test bed and carried out performance evaluation under various scenarios to enhance the applicability of the SCND by varying locations, number of facilities and product combinations. The ultimate objectives of the work were to minimize total supply chain network design cost including variable cost and maximize organization's customer service potential and provides a comprehensive analysis of the firm's supply chain structure and performance through pre-defined set of scenarios.

“…Nekooghadirli et al (2014) presented a bi-objective and multi-product model for the LIRP problem where the total cost and maximum average time of delivering products to customers is minimized, simultaneously. Ambrosino and Scutella (2005) have considered the LIRP problem with four layers including the plant, central warehouse, regional warehouses and customers. The aim of their problem was to determine the location and number of different facilities in a new network or to improve an existing network.…”

Locating, routing and inventory control in production and distribution centers are the most important decisions in supply chain management. Because of the dependence of these decisions to each other, considering these three aspects simultaneously can have a huge impact on cost reduction. In this study, first, a location-inventory model is developed by utilizing METRIC approach and then, METRIC approach is applied to the location-inventory-routing model. The intended supply chain includes a supplier, distributors and retailers, and the inventory control policy is implemented for both the distributors and retailers. Retailers' demand follows Poisson distribution and the lead-time is also considered probabilistic and is affected by the shortage in distribution centers. Given that the presented model belongs to the class of NP-hard problems, a hybrid metaheuristic solution method is also presented to solve the resulted problem. The proposed hybrid metaheuristic algorithm contains a Simulated Annealing algorithm, to optimize the location-routing problem, and a Genetic Algorithm, to optimize the inventory problem. Also, to evaluate the performance of hybrid algorithm, a comparison between the results of the proposed hybrid algorithm and the exact solutions obtained from Lingo software is provided and, finally, the results are analyzed.Growing Science Ltd.
