A Flow Shop with Compatibility Constraints in a Steelmaking Plant* Abstract We present a scheduling methodology for applications where the generation of schedules is constrained by antagonistic and vague Besides temporal and capacity constraints， compatibility constraints between consecutive jobs are We model the vague constraints and uncertain data by fuzzy set The importance of single jobs and the difficulty to schedule them is defined on the different constraints and is used to control the generation of A preliminary schedule is generated by considering the important jobs and those that are difficult to schedule Easy or not so important jobs are scheduled Finally， the achieved schedule is “repaired” until a schedule is found that achieves a given level of Since the goodness of solutions is rated by fuzzy sets， robust schedules achieve better evaluations than weak However， if no robust solution is found constraints will be This methodology is appropriate for applications in process engineering where uncertain knowledge is We explain the methodology with a case study from a steelmaking plant for high-grade steel流动性约束与铺在炼钢厂* 摘要 我们提出一个调度方法的应用产生的时间表而受到限制对立和模糊的知识。除了时间和能力的限制，兼容性限制之间连续工作的管理。我们模型的模糊和不确定的制约因素数据的模糊集理论。单一的重要性和困难的工作安排次 时间是指在不同的制约因素，是用来控制生成的时间表。初步安排是考虑到所产生的重要的工作和那些有困难的时间表第一。容易或不那么重要的工作计划之后。最后，实现的时间表是“修复” ，直到一个时间表，发现达到某一特定的满意程度。因为善良的解决方案是评价模糊集，强大的时间表实现更好的评价比弱时间表。但是，如果没有强有力的解决办法是找到制约将会放宽。这种方法适合于工程应用过程中在不确定性知识为主。我们解释方法，个案研究从炼钢厂的高档钢材。但愿能帮到你，希望采纳！
When my father was young， he practiced Chinese calligraphy every day and enjoyed Peking Opera with my grandfather on Now as his daughter， I type in English when communicating with my friends and enjoy surfing on the Internet during When I enjoy the pleasure and convenience that new technologies have brought me， some people cry out that as technology develops traditional cultures must be Is it true that we cannot have both? Different as my lifestyle is from that of my father， I still believe that the development of technology won＇t lead to the loss of On the contrary， it will facilitate the development of traditional Some people draw the conclusion that technology leads to the loss of tradition because they find nowadays many people，especially the young， take interest in new things like the Internet， thus make less contact with traditional However，decreased popularity isn＇t equal to With the development of technology， we have more choices of arts and In other words， many new forms of culture are coming into existence， which provide people with more choices rather than threaten the existence of the traditional In actuality， if we look at the tradition itself， we can find that great achievements have been made in many fields with the development of New operas are on show; new researches about history are going on; new facts about historical cities have been found; all of which can prove that technology can stay peacefully with In fact， technology works far beyond The development of technology boosts that of the On one hand，new technologies make the research for traditional cultures possible as well as provide advanced techniques of reserving historic Take calligraphy as an example， new ways of illumination， which is the fruit of Hi-tech， can prevent the color of scripts from On the other hand， the rapidly developing media such as the Internet and communication satellite provide traditional cultures with a stage to face the whole As we can see， after the short piece of ad of Shanghai E ， more people will know the beautiful melody of "J"In addition， if we look back to history， we can find out that it was always in the era when economy developed greatly that cultures prospered the No doubt that the development of technology can guarantee that of economy， which eventually influences the prosperity of As we all see， the development of technology brings us richness， making the research and development of cultures affordable brings us more leisure time， making our desire to enjoy ntertainments After all， as the great philosopher Marx aid， "economy determine
PrefaceThe ARPANET – the Department of Defense network that is the ancestor of today’s Internet—was built in the late sixties using a proprietary protocol This first protocol proved to have shortcomings for linking with other networks， which led to the development of Transfer Control Protocol/Internet Protocol (TCP/IP) TCP/IP used 32-bit address These soon proved to be unwieldy for most users， even when expressed in the less daunting formant of four 8-bit decimal numbers， delimited by The obvious solution was a scheme for addressing computers by After all， people relate much better to names and find it much easier to remember the computer in the corner as “Frodo，” rather than “”The First Generation: Hot TablesThe desire to refer to machines by name instead of number led to the first IP address management scheme: the host The host table is a file that contains all the IP address in use on a network， along with their The host table provides a mapping from a host’s name to its IP address， as well as reverse mapping: Given a host’s IP address， the user can look up its For a host table to be most user useful， it must contain the names of all the hosts with which a given host might want to For the ARPANET， that mean that the host table had to contain the names and IP address of every host on the Such a file was maintained by the Network Information Center (NIC)， the central organization responsible for managing the ARPANET The file was called HOSTSTXT and was similar in format to the/etc/hosts file on UNIX Network administrators all over the network e-mailed host table changed to the NIC every time they added or deleted a host or changed a host’s IP The NIC made the changes to its master host table， which it made available via File Transfer Protocol (FTP) Administrators periodically downloaded the latest version of the host table to stay
