Cold Chain Logistics Distribution Network Planning Subjected to Cost Constraints

In order to reduce the loss in the circulation of agricultural products, and to reduce the total cost, this article minimizes the operation cost by establishing an objective function when designing the cold chain logistics distribution network. Considering the characteristics of the cold chain products, this paper regards construction cost of network nodes, transportation cost and damage cost as the main factors in establishing an objective function. As the cold chain logistics is correlated to the demand of time, this article comes up with a concept of service radius, which transformed the transportation time between logistics nodes into the radius of logistic nodes. The model is verified through a series of constraint conditions to express the relationship between the various decision variables. An example is given in the end, which demonstrates the application of this model in a vegetable firm distribution logistics network planning. The final computation results illustrated that the model is effective.

The queries are decomposed and composed to obtain and synthesize data from all the underlying data sources to trace food information for effectively tracing locations of questionable foods. The work is very important to prevent more spreads of food safety emergencies.

Impact Analysis of Air Pollutant Emission Policies on Thermal Coal Supply Chain Enterprises in China

Spurred by the increasingly serious air pollution problem, the Chinese government has launched a series of policies to put forward specific measures of power structure adjustment and the control objectives of air pollution and coal consumption. Other policies pointed out that the coal resources regional blockades will be broken by improving transportation networks and constructing new logistics nodes. Thermal power takes the largest part of China’s total installed power generation capacity, so these policies will undoubtedly impact thermal coal supply chain member enterprises. Based on the actual situation in China, this paper figures out how the member enterprises adjust their business decisions to satisfy the requirements of air pollution prevention and control policies by establishing system dynamic models of policy impact transfer. These dynamic analyses can help coal enterprises and thermal power enterprises do strategic environmental assessments and find directions of sustainable development. Furthermore, the policy simulated results of this paper provide the Chinese government with suggestions for policy-making to make sure that the energy conservation and emission reduction policies and sustainable energy policies can work more efficiently.

Study of the TRanspyrenean Corridor in Comparison with Other Corridors in the Iberian Peninsula Using GIS Tools

This work is part of the collaboration agreement that Zaragoza Logistics Center maintains with Fundación Transpirenaica to promote, encourage and boost the role of rail in the Peninsula and Europe As a result of the need to plan new routes for the transport of goods, in a more agile and flexible way to Europe, and given the current competition between peninsular logistics nodes, this paper aims to demonstrate the possibility of the coexistence of several corridors in the same territory, and its complementarity regarding certain studied parameters. The main objective of this study is to implement a spatial analysis of the hinterland of the Transpyrenean corridor using GIS (Geographic Information Systems) tools over other alternative corridors within the Iberian Peninsula for the transport of goods. For this analysis, we have used a number of variables, such as GDP (Gross Domestic Product) per capita, population density and proximity to the most important logistics nodes, which let us establish the comparison between corridors. The paper is structured as follows: First, it specifies the scope and objectives. Next, it describes the GIS tool used for the analysis and the necessary elements to set the scenario, such as cartography and attributes as well as other resources necessary to develop the maps. Third, it explains how to build and order information layers to represent spatial data after setting the coordinate system. Finally, it reflects the results and details the information that each one contains, and the main conclusions derived from them.

3D Animation of the Transpyrenean Corridor Created by GIS Tools

The Transpyrenean Central Corridor plays a vital role in the transportation of goods from the Atlantic ports to the North of Europe. In the European context, the central corridor was originally called Priority Axis Number 16th in the Trans-European Transport Network. Afterwards, it became one of the objectives of the global network for 2050. This work is part of the collaboration agreement that Zaragoza Logistics Center maintains with Fundación Transpirenaica to promote, encourage and boost the role of rail in the Peninsula and Europe. The main objective of this work is to demonstrate the relevance of each logistic node (ports, airports, rail terminals, logistic platforms, etc.) through which the Central corridor passes using three-dimensional animation. In this way its geostrategic position is clearly in evidence and the large economic impact derived from its interconnectivity with ports, airports and transport and logistic infrastructures. The paper also aims to reflect the low environmental and territorial impact that this freight rail corridor represents, respecting natural parks and protected areas, showing in turn the viability of the route for low-slope areas. The rail corridor begins in Algeciras (Spain) and Sines (Portugal) and ends in Paris; for stretches of the route whose current state is not fully defined (under construction, projected future, studying alternatives, etc.), the most reasonable current scenario has been used. The article is a description of the methodology of a 3D animation generation of a corridor where some challenges such as the management of layers and the recording compilation have been overcome. Therefore, the methodology can be applied to any other case study, not only a road infrastructure but even a river, a valley, etc. The range of stakeholders that would benefit from this work goes from entities such as Fundación Transpirenaica–in their promotion of the corridor capacities–, the Administration–to show the feasibility of the path–, and in general companies interested in extending the concept of supply chain management to other geographical areas and also interested in the use of intermodal modes for that end.

Then, the number of logistics parks, logistics centers and distribution centers is calculated based on the logistics volume of Inner Mongolia in 2014. Moreover, a reasonable three level logistics nodes location of Inner Mongolia is proposed considering of several factors.

An optimal hierarchical decision model for a regional logistics network with environmental impact consideration.

This paper proposes a new model of simultaneous optimization of three-level logistics decisions, for logistics authorities, logistics operators, and logistics users, for regional logistics network with environmental impact consideration. The proposed model addresses the interaction among the three logistics players in a complete competitive logistics service market with CO2 emission charges. We also explicitly incorporate the impacts of the scale economics of the logistics park and the logistics users' demand elasticity into the model. The logistics authorities aim to maximize the total social welfare of the system, considering the demand of green logistics development by two different methods: optimal location of logistics nodes and charging a CO2 emission tax. Logistics operators are assumed to compete with logistics service fare and frequency, while logistics users minimize their own perceived logistics disutility given logistics operators' service fare and frequency. A heuristic algorithm based on the multinomial logit model is presented for the three-level decision model, and a numerical example is given to illustrate the above optimal model and its algorithm. The proposed model provides a useful tool for modeling competitive logistics services and evaluating logistics policies at the strategic level.
