The motion that the crane simulator renders through the motion simulation platform, usually a 6-DOF Steward platform, can be divided into two types, the large-scale one and small-scale one. The later refers to the oscillation that the driver feels when he is operating the machine. In order to obtain the driving function to make the motion platform to render the motion of such small-scale type, it...
Delivery time is an important variable in purchasing and supply chain management. In this paper, we discuss two issues: (1) Integrated management for delivery time, which suggests a synchronous, systemic and total managerial principle for delivery time management; (2) Coordinative decision-making for delivery time, which presents a conceptual framework model for delivery time decision-making. The...
Supplier management is one of the most important components of purchasing and supply chain management. This paper explores the supplier management process, and according to the process, identifies five principal contents of supplier management, that is, supplier selection, quality, performance, relationship and development. Through this study, the processes and contents of supplier management in modern...
Radio-wave attenuation negatively affects RF communications in a RFID system. In order to ensure the reliability of RFID system, one must predict the radio-wave path-loss accurately before detailed design. However, it is infeasible to estimate the path-loss for the container RFID systems using the conventional path-loss models such as the Okumura model, two-ray model and so on. This paper firstly...
The issue of the modeling for the distribution management based on demand forecasting. ANN model is applied to the field of demand forecasting. The modeling of market demand forecasting is built using BP algorithm. The model of forecasting is established by Simulation model of MATLAB. Based on them, a simple numerical example is given to test and forecast with three-layer BP network model.
This paper presents a case study to apply the RFID (Radio Frequency Identification) technology to dynamically track miscellaneous logistics information of the shipping containers to improve the container transportation management and digitalization level. The system architecture and configuration of the RFID system are illustrated and the requirements of the container RFID system are characterized...
With the penetration of electronic commerce, centralized electronic purchasing will be a kind of efficient tool for Group Co. to reduce cost of purchasing and improve its competency. Advantages and disadvantages of electronic centralized procurement was analysed. Based on the feasibility analysis of the implementation of electronic centralized-decentralized procurement in Handan, Hebei Transportation...
As one of the key elements of development strategy of port, a proper logistics mode according to the condition and features of the port plays vital role in elevating the strength of the port in the increasing fierce competition. At present, so many candidates of logistics mode are facing the port. In this paper a decision-making model for logistics mode of port basing on fuzzy comprehensive evaluation...
