To ensure the normal production, it is necessary to have a safety inventory as a buffer. Safety inventory is mainly affected by the following factors: the expected customer service, the mean value and standard deviation of the lead time, the mean value and standard deviation of demand. We build a system dynamics model to analyze impacts of the several factors above on the safety inventory. We design...
An important characteristic of electrical vehicle is that there is high voltage of power cycle. The passive safety is very important in electrical vehicle's crash, compared with normal vehicle. First, the crash standard of electrical vehicle is analyzed. Then the crash test's process is researched. With the dummy's injury data of head and thorax and vehicle's acceleration, which come from different...
The paper establishes the knowledge complex mode of design rules of civil avionics Integrated Intelligent Flight Deck Displays aiming at its peculiarity of operation and being based on the experienced data being evaluated by the resourceful pilots, an algorithm is proposed which using rough set to reduce the data and give a knowledge reduction and rule extraction algorithm based on a comprehensive...
Semiconductor bridge (SCB) has been widely used for both military and civilian igniting application for its improved performance in terms of high safety, low ignition energy, short ignition time and its integration into the digital circuits. Here we report the temperature and heat variation laws of bridge area on SCB under the constant current via infrared thermal imaging. The results indicate that...
The most fundamental means of maintaining mechanical safety is to systematically carry out safety design and analysis in the mechanical design process. The fuzzy comprehensive evaluation method is to take the advantages of the level analytic hierarchy process and fuzzy comprehensive evaluation method. Firstly, the evaluation index system is divided into ladder level structure, calculated the index...
The network security situation perception technology as active defense technology has become the new research direction of network security field. On the basis of analyzing and summarizing the basic concept and the model of network security situation perception, put forward a method of network security situation perception based on artificial life. This method builds an artificial life model which...
