油料装备信息化的接入模式分析 总被引:2,自引:2,他引:0
给出了油料装备信息化中几种常见的信息接入方式:嵌入式系统、条码、射频标签,并对其进行了分析和比较。通过比较,认为嵌入式系统方式、射频标签方式具有较好的环境适应性、保密性和信息可读写性,大型油料装备的信息接入可采用这两种方式;二维条码因成本较低、具有一定的信息容量,可作为油料化验箱等小型装备器材的信息接入方式。最后对被覆线、卫星和短波电台3种信息传输方式的性能进行了比较。 相似文献

This article surveys the body of available evidence regarding the spill-over effects of defence R&D. It reviews the routes through which defence R&D spills over to the economy with positive externalities – in terms of new products, technologies or processes; the barriers that impede or block such a process; potential negative repercussions, and the measure of such effects. The main conclusion is that the uncertainty of these effects, and the inaccurate appraisal of their value, hardly supports informed decisions concerning defence R&D policies. 相似文献

This article treats an elementary optimization problem, where an inbound stream of successive items is to be resequenced with the help of multiple parallel queues in order to restore an intended target sequence. Whenever early items block the one item to be currently released into the target sequence, they are withdrawn from their queue and intermediately stored in an overflow area until their actual release is reached. We aim to minimize the maximum number of items simultaneously stored in the overflow area during the complete resequencing process. We met this problem in industry practice at a large German automobile producer, who has to resequence containers with car seats prior to the assembly process. We formalize the resulting resequencing problem and provide suited exact and heuristic solution algorithms. In our computational study, we also address managerial aspects such as how to properly avoid the negative effects of sequence alterations. © 2016 Wiley Periodicals, Inc.
