This paper reports on a large, long-term mobile wireless sensor network deployment. The trial was part of an animal study involving 45 animals. During the trial, 15 animals were equipped with wireless sensor nodes for a week. The paper discusses various issues with such a deployment including electronic design, software design, animal ethics clearance, logistics, and wearable computing equipmen...

In logistics management, selecting the carriers to deliver freight is a critical process for global enterprises. This paper determines the optimal carrier selection based on a multi-commodity reliability criterion for a logistics network subject to budget. Traditionally, a logistics network includes nodes and routes connecting the supplier and customer. Along each route, several carriers are av...

Consider a congested urban logistics network with one depot and many geographically dispersed retailers facing demands at constant and deterministic rate over a period of planning horizon, but the lead time is variable due to traffic congestion. All stock enters the logistics network through the depot and from where it is distributed to the retailers by a fleet of vehicles. In this paper, we pr...

One of the most important concerns of reverse logistics network design is to locate interacting facilities in an efficient and cost effective manner, which forms a typical hierarchical system with multiple layer configuration. Considering the hierarchical relationship and flow of waste among the different facility types, both single-flow pattern and multi-flow pattern are discussed in this pape...

Attention with reverse logistics networks has increased during the last decade since their economic impact has been increasingly important and as environmental legislation has been becoming stricter. In this paper, A multi-period multi-echelon forward–reverse logistics network design under risk model is developed. The proposed network structure consists of three echelons in the forward directio...

today, due to the direct and reverse logistics plays an important role in reducing the costs in supply chain. in this paper, in order to provide a closed-loop supply chain network including supply centers, production, distribution, collection, recycling and disposal of a used linear mixed integer programming. this paper to consider multi-period and multi-product in multi-level supply chain and ...

In order to ensure the balance of trunk transportation resources, logistics enterprises generally require transport vehicles return initial distribution after completing task, so as facilitate next phase operations. Most waste resources in whole process transportation. At this time, we need choose a comprehensive network optimization method improve vehicle loading rate, reduce cost, and design ...

In this work the design of a reverse distribution network is studied. Most of the proposed models on the subject are case based and, for that reason, they lack generality. In this paper we try to overcome this limitation and a generalized model is proposed. It contemplates the design of a generic reverse logistics network where capacity limits, multi-product management and uncertainty on produc...

This text proposes a mathematical programming approach to design international production-distribution networks for make-to-stock products with convergent manufacturing processes. Various formulations of the elements of production-distribution network design models are discussed. The emphasis is put on modeling issues encountered in practice which have a significant impact on the quality of the...

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 a...
