Reliability and safety is very important for logistic equipments especially sorting system. In this paper a novel structure of automatic sorting system is designed based on Double 2 vote 2 Redundancy (D2V2R) structure. By using this structure, the reliability of the system is enhanced comparing with traditional simplex system and duplex system. Analytical results based on basic reliability analyzing...
This research was based on previous studies, combined with their own university Case Analysis, Analysis of the best domestic and international dimensions of human resource management literature and a large number of human resource management in Chinese Universities on the basis of the actual situation, make the most of University Human Resource Practice good dimension for the college to improve organizational...
Evaluation of risk in emergency material reserve entrusted to other enterprises is premise and foundation of controlling risk in reserve by others. In this paper, risk of emergency material reserve entrusted to other enterprises was analyzed. Quantitive model of evaluation on risk in emergency material reserve entrusted to other enterprises was proposed. It is helpful to recognize the size of risk...
As market competition intensifies, numerous enterprises transfer auxiliary logistics functions to professional logistics service provider (LSP) in order to enhance their core competitiveness. Reasonable and practical evaluation method is premise of selecting LSP which is suitable for the enterprise. A comprehensive evaluation index system is established based on the requirements of various factors...
According to the issues of the fourth party logistics platform usability, this paper analyzes the usability factors which influenced the platform from the perspective of third party logistics member and consignable company, and the evaluation index system of fourth party logistics platform usability was determined according to the designing, analysis and correction of questionnaire. And this paper...
Supply Chain Management (SCM) is now an important strategy for companies to gain competitiveness. However, the cost is still the key factor to face. This paper proposes a novel approach to create an optimal logistic plan in SCM with failures such that the required total capacity for logistics is minimum while the reliability retains the highest. Since the globalized economics changes very fast, the...
Supply Chain Operations Reference (SCOR) model is developed and maintained by the Supply Chain Council (SCC). The model is a reference model which can be used to map, benchmark and improve the supply chain operations. SCOR model provides companies with a basic process modeling tool, an extensive benchmark database and defines a set of supply chain metrics. Mobarakeh Steel Company (located in Isfahan,...
Repeated infrastructure construction and decentralized logistics resources problems nowadays in domestic logistics industry had severe influences on social logistics efficiency, thus hindered the development of modern logistics industry. According to the theory of logistics network, logistics network is the best way for improving logistics efficiency. This paper first puts forward a new concept, logistics...
We describe a kind of supply chain optimization problem as a commodity stream routing problem upon a stochastic flow network. We divide the optimization problem to two parts: Firstly, establish model to calculate the optimal commodity stream allocation policy on all minimal paths; secondly, convert these allocation policy on all minimal paths to the optimal routing policy on all arcs. A multi-objective...
One essential requirement for WSN is the reliability of the applications. Performance evaluation, therefore, is of great significance before the successful deployment of the network. In this paper, we consider the reliability based on a specific type of network lifetime. Our network lifetime is defined based on the representative consideration of coverage and connectivity and has a common application...
The introduction of PHM based RCM has been a slow process and may be too big a step to be achieved in a single bound. We need an incremental way forward that deploys the elements of RCM founded on PHM such that each step is self-financing and lays the foundations for the next stage of deployment leading to a finished system and process. PHM based RCM is focused on the deployed equipment and its components:...
Application of the Perfect Combinatorial Sequences Theory, namely the concept of Ideal Ring Bundles (IRBs), for improving the quality indices of engineering devices or systems based on combinatorial technique is proposed in the paper. For example, resolving ability of radar is known to be of very dependent from positioning of elements in antenna array; high-performance technology of information coding...
Prognostics and health management (PHM) is a methodology that permits the reliability of a system to be evaluated in its actual life cycle conditions in order to predict when and where failures will occur and to mitigate system risks. In this paper we discuss the benefits of prognostics in systems. These benefits relate to system design and development, reliability, safety, maintainability, logistics...
Each project is expected to encompass some unique requirements and performance criteria that would require the Reliability and Maintainability (R&M) lead to exercise some level of innovation; but with professional growth the implementation of an R&M program for a known application and similar complexity of legacy programs, successful implementation becomes less and less challenging over time...
Accurate modeling of a system's operational availability is vital to determine its sparing needs. Two different families of sparing tools are available to model operational availability. The first was designed for use by the logistics community and the second was designed by the reliability community. Both of these families of tools were analyzed to obtain an understanding on their differences for...
The characteristics of natural radio communications and the disturbances of application environment inevitably lead to the unreliable phenomena of duplicated readings, false positive reading and false negative reading when RFID is applied to logistics tracking system, and numerous unreliable data are generated. To solve this problem, a series of evaluation indexes for evaluating RFID application reliability...
To locate the dairy distribution center (DC), reliability is cosidered as a measure of distribution sevice level, instead of only taking distribution cost into account. A mathematical model is presented. Firstly the existence and calculation of reliability are described in detail. Then genetic algorithm is used to solve the model, and the optimal solution of the model was obtained by selecting the...
Estimating containership arrival rate is a key element in harbor operation and management; however, it is not easy to be described because of a wide range of external factors. Most of the literature discussing arrival processes is based on a homogeneous Poisson process, which is unable to describe the fluctuation status of growth or recession. In the paper, we propose the Non-Homogeneous Poisson Process...
As part of solutions to the technical problem of logistics distribution, vehicle routing problem (VRP) is getting more and more attention in academics and enterprises, it belongs to the NP-hard problem theoretically. VRP with time windows and capacity constraint in stochastic traffic network was studied based on travel time reliability . Firstly, travel time was expressed as a random variable according...
This paper presents a hybrid multi-criteria/fuzzy method for the selection of the carrier among a number of pre-selected logistic service providers. The method was developed and applied to the case of a multinational company in the power-electronic market. Finally, an automated system supporting the decisional process was designed to support users.
