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！
写作思路：根据为科技主题，以为发展基调来展开描写，紧扣叙述与描写的内容，力求做到不突兀、不生硬，不长篇大论或肆意抒情，有情真意切之感。范文：It can be expected that there will be a breakthrough in life sceience and space science in the 21st century First， scientists will conquer incurable diseases through the transformation of genes可以预见，21世纪生命科学和空间科学将取得突破性进展。首先，科学家将通过基因转化来战胜不治之症。With the same technology they can breed new species of animals and even human life in the laboratory Most important of all， they can decelerate aging and prolong life用同样的技术，他们可以在实验室培育出新的动物物种，甚至人类的生命。最重要的是，它们能延缓衰老，延长寿命。Besides， permanent stations will be set up in the moon or other planets or stars so that scientists can make a thorough study of the moon and other planets or star此外，还将在月球或其他行星或恒星上建立永久观测站，以便科学家对月球和其他行星或恒星进行深入研究。扩展资料英语想写好作文，必须具备扎实的基本功，作文的基本功主要体现在词、句、段三个方面。单词方面，积累单词，扩大词汇量，弄清词的确切用法及相似词的用法区别，以及很多固定短语、习语的用法，要准确地表达想要表达的意思。句子方面，注意一些常用的句式，平时看到比较好用的句式要记下来，多模仿，还要在写文章时注意长短句的结合。段落方面，注意整篇文章的整体布局，要从整体上把握每段的中心思想，避免偏题、走题。提高写作水平不是一朝一夕所能完成的，最重要的是养成好的学习习惯，平时注意多积累，勤动笔、多思考，潜移默化中写作水平便会不断提高。
Science and technology have changed our life thoroughly throughout the history，especially in the last There is a prevailing understanding about science and technology among the general public that they are the same thing of two different names but they are acutally two Science is kind of series of theorrtical concepts and people can accept it or not，and it will not affect commom people's life to a large extent，but it's a different way when it comes to technology because technology has more pratical effect on People have to endure the results of the pactical applicance of technology whether they are good or not，such as the air pollution，and it all happens without people's acceptance，for it all depends on the local governments' or even the nations'
The new century is It can be expected that there will be a breakthrough in life sceience and space science in the 21st First， scientists will conquer incurable diseases through the transformation of With the same technology they can breed new species of animals and even human life in the Most important of all， they can decelerate aging and prolong Besides， permanent stations will be set up in the moon or other planets or stars so that scientists can make a thorough study of the moon and other planets or Most probably life will be found in other stars in universe or the planets or stars suitable for the human existence will be However， the scientific development will also bring about some social How should we regard from an ethical perspective the one who is bred through the gene technology in the How can the police identify the criminal from a group of people with the same DNA? It is quite natural that we will meet problems in the scientific and social Therefore， we should be prepared to meet new 汇众动漫学院
