In this paper, we integrate two independent multiplicative uncertainties (uncertain demand and cost) and facility disruptions together, introduce budget uncertainty set to capture uncertain parameters. Based on the underlying deterministic model, we propose a two-stage robust facility location model, incorporating facility disruptions in recourse stage, which is an nonlinear problem resulted by two...
Freight and passenger carriers deploy large hub-and-spoke transportation networks to provide efficient service between many origins and many destinations. These networks use hub facilities that provide a connecting, sorting and/or consolidation function designed to concentrate flows on the inter-hub links to exploit the strong economies of scale in transportation. Yet examination of the optimal solutions...
To improve integrated forward/reverse logistics management performance, an appropriate design approach for the forward/reverse logistics network structure and logistics operation schedule is proposed. Synthetically taking into account the location problem and inventory relationships of inter-related nodes, a location-inventory (LI) model is developed. With the help of the model, the following items...
With the development of E-business, reverse logistics become the important problem in enterprises, they can increase service quality and enterprises profit by improving reverse logistics system. In this compete environment, how to build an effective reverse logistics system and make a proper plan for the distribution centre location has become a challenge. This paper proposed a model based on 0-1...
The location and allocation of regional distribution center is the key problem of logistics distribution network, it concerns that whether the distribution system can perform efficiently. The paper sets up a mathematic location model of generalized transportation costs on basis of economic scale, and then solves Location and Allocation Problem of regional distribution center by means of Fuzzy graph...
Location Set Covering Problem (LSCP) is a traditional problem in the location literature. LSCP is used in locating fire stations, computer networks, and many other service facilities. This paper proposes a covering problem with variable radii. In this problem, the cost to establish a facility is a monotonically increasing function of distance to the farthest covered node by the facility. The problem...
In recent years, companies have broadened their competitions in different directions such as distribution, customer service, and retailing. Therefore, different retailing formats appear in the market increasingly and the convenient store becomes one important format among them. To achieve better performance of the logistic network, selecting suitable convenient store location is a pertinent decision...
The paper presents a novel Multi-Resolution Model (MRM) of Logistics Location based on the theory of Multi-Resolution Modeling. Using MRM simulation thoughts, it points out the necessary of MRM of Logistics Location by analyzing the key technology of MRM. MRM utilizes Cost - Revenue model(C-R) based on Fuzzy Multiple Attribute Hierarchical Macro Location model (FMAHML) in macroscopic and mesoscopic...
According to the logistics node location of the preferred option is to make its goods through the logistics node collection, transfer, distribution, until the point of delivery to the needs of the whole process's best efficiency, using AHP and the 0-1 integer programming combined model methods, to select logistics nodes and combination of suppliers. MDL, for example in order to show that the minimum...
We summarized recent research aimed at expanding the context of facility location decisions to incorporate additional features of a supply chain including variable construction cost, inventory management, transportation cost, etc. Authors expended location model of risk pooling with variable construction cost (LMRPVCC) to construct location model of risking pool with variable construction cost with...
In this paper, we develop a novel multi-echelon joint inventory-location problem that considers location and inventory decisions simultaneously. The model deals with the distribution of a single commodity from a single manufacturer to a set of retailers through a set of sites where distribution centers can be located. The retailers face deterministic demand and hold working inventory. We assume single...
Timeliness is one of the most important objectives that reflect the quality of emergency rescue. To provide timeliness, the most obvious way is to increase the number of service facility available. Unfortunately, increasing the number of facility is generally impossible due to capital constraints. In such a case, the strategy for emergency facility location becomes a crucial issue. This artic discusses...
Before constructing a new public transportation pivotal facility, an important problem is to estimate and analyze the market share or attracting area of this transportation facility. In this paper, a multi-class continuous equilibrium model is given and proved to satisfied user equilibrium condition and other constraint conditions. The case of traveler choice behavior is considered. An efficient iterative...
With the people's attention to the product quality and the environmental protection consciousness enhancement, the reverse logistics start to cause continuously attention of people. More and more scholars research the origin, the concept, the classification of the reverse logistics. At present there are some researches of the reverse logistics, however, these researches are restricted only in the...
In the early of 1990s, reverse logistics was beginning to be widely concerned by some developed countries, as the government and consumers were more attached importance to environment. China had paid more attention to forward logistics, but there is little concern about reverse logistics. As China entered WTO, companies will be confronted with fierce competition. It is necessary for Chinese companies...
Due to the environmental protection and the remaining economical value in the used products, this paper presents a three-stage reverse logistics network problem with incentive payment and formulates a mixed-integer nonlinear facility location model to determine the optimal number and locations for collecting centers and reprocessing centers so as to minimize the total cost. Since this problem is NP-hard,...
This paper describes a model that seeks to simultaneously optimize the location of multiple-server, congestible facilities in order to realize company's maximal total captured demand. The effective demand at each customer demand node is elastic to the travel cost to the facility, and to the congestion at that facility. We propose a greedy heuristic for the resulting problem formulation, and provide...
In consideration of economy of distance and economy of scale, the establishment of exclusive recycling center is the optimal choice for resource-efficient reverse logistics. Aiming at how to determine the location of reverse logistics centers and the recycled amount of scrap goods, the article has established a non-linear mixed-integer programming model with the minimum total cost as the objective...
Traditionally, the uncapacitated facility location problem (UFLP) is solved as a single-objective optimization exercise, and focuses on minimizing the cost of operating a distribution network. This paper presents an exploratory study in which the environmental impact is modelled as a separate objective to the economic cost. We assume that the environmental cost of transport is large in comparison...
This paper is to apply a new fuzzy multi objective approach for locating undesirable facilities and hazardous materials. This paper considers a location problem for collecting hazardous materials with two fuzzy parameters in multi objective decision making (MODM) environment. There are two objects in proposed model, first one emphasizes on minimizing total transportation cost and fixed cost, second...
