the assumption of a xx seems to be too restrictive or inadequate, the formulation with Fuzzy termination time, i.e.given by a fuzzy set in the space of control stages, may be applied.l We assume here the fuzzy constraints to be state‑dependent, and the fuzzy goal to be the same for all the control states, xx, which stems from the problem's nature.l An approach to the solution of this problem is presented under the assumption that the sampling rate Decision can be made prior to the execution of the experiment, as opposed to being made while the experiment is in progress.l Another assumption made above is that there are precise odds at which the expert is indifferent.l Main simplifying assumptions are:l This, in our view, is a questionable assumption.Outline / Structure / Modulel An

of the integrated system.l The model consists of four rule bases, each of which addresses a separate problem in the hierarchy of scheduling decision.l The rule bases are linked to each other in a chin‑like manner in the sense that the consequent of one rule base constitutes a part of the antecedent of the next rule base.l The rule base consists of all possible combinations of the linguistic terms associated with the linguistic variable of the antecedent of a rule.Computer Systeml The system has been implemented using prolog language in an MS‑DOS environment.prolog was chosen because it offers a well known and flexible environment in which fuzzy reasoning may be easily implemented.l The current version of the xx program when compiled with WATFOR77 results in an executable code of about 270K bytes.Typical run time, when run on a XX computer(an IBM compatible machine)operating at 4.77 Mhz with 640K RAM, ranges from 10 min to 2h, depending on the size(or complexity)of the problem.l Time consuming procedures have been implemented in C‑language and directly linked to the prolog environment.l The xx process, once the xx's data has been entered, requires approximately 180 seconds.l It should be noted that the computation was done with a 20 Hhz, 80386‑based microcomputer equipped with a 80387 math co‑processor.l The computer programs used for the analyses, one based on the xx method and the other based on the new method, were written in FORTRAN with a compiler that supports the math co‑processor.l Lisp, prolog give maximum flexibility but also maximizes development time.l Internal representation is the way a model is represented in the computer.l An interactive menu-driven procedure is used in this studyl Shell can be develop very fast at the cost of time fairly severe limitations.l While there is no measurable saving of time for the case involving five criteria, the saving is dramatic for the case involving 10 criteria--the computation time reduces from 10 hr 40 min to about 1 min.l This combination is being implemented in an objected‑oriented programming environment(Smalltalk‑80 system)to solve problems encountered in construction xxx.Method / Approach

completed model should agree with the formula.l For manufacturing purposes, a detailed and precise model of the object is necessaryl Engineering design models are very well defined;therefore, l To keep the domain narrow enough to be implementable, yet wide enough to be useful.point of Viewl from an implementation standpoint,l From the point of view of this application,l From this point of view, Zadeh suggested an inference rule named xxx(CRI for short).l Information is the meaningful interpretation and correlation of some aggregation of data in order to allow one to make decisions.l From a practical point of view, the computational aspects of an FLC require a simplification of the fuzzy control algorithm.l The use of a hammer to insert screws, although partly effective, tends to distort, destroy, and generally defeat the purpose of using a screw [Kusiak AI Implications for CIM p.129]Justificationl We choose the so called xx in our experiment because it has received wide acceptance and canl prolog was chosen because it offers a well known and flexible environment in which fuzzy reasoning may be easily implemented.l The rationale behind this is that it can be much easier for an estimator to rate a cost as high than to attempt to place a dollar value on the estimate.l This strategy has been widely used in fuzzy control applications since it is natural and easy to implement.l A function definition expresses the membership function of a fuzzy set in a functional form, typically a bell‑shaped function, etc.Such functions are used in FLC because they lead themselves to manipulation through the use of fuzzy arithmetic.l It should be noted that in our daily life most of the information on which our decisions are based is linguistic rather than numerical in nature.Seen in this perspective, fuzzy control rules provide a natural framework for the characterization of human behavior and decisions analysis.l Many experts have found that fuzzy control rules provide a convenient way to express their domain knowledge.This explains why most FLCs are based on the knowledge and experience which are expressed in the language of fuzzy “if‑the” rule.Chapter 4.ExamplesExample/ Datal The data used in the following example was taken from an experiment in which xx was measured between x and x using a xx technique.l The data consists of over xx measurements.l An example of xx is discussed and the control rules of xx are compared with a xxl Examples of complex processes to which this technique may be applied are xx, xx, etc.l The following example is constructed only for the purpose of illustrating the computational procedure discussed.l This example clearly demonstrates that the profile of an inpidual xx, or a very small group of xx, with no enough data to be studied statistically, can be meaningfully analyzed by fuzzy possibilistic methods.l There is no space here to go into detail on all these methods, but deserve a mention and the bibliography will point to detailed references for those wishing this level of detail.l Note that the golf ball spotting example is used throughout the paper.Comparisonsl As well, the pros and cons of these representations from a process planning point of view will be discussed.l The method of using xx to implement xx described by Zadeh(1973)appeared more suitablel As discussed [in the previous section]/[preciously],Relationl We can not invert F' directly because it defines a many-to-one mapping.l The relationships appear very complicatel Lifting tasks involve complex and imprecise relationship between the task variables and the human operator's characteristics.l These methods are based on the relationship between...and...l The fundamental concept of a fuzzy rating language is that we can establish a relationship among terms such as high, medium, and low, and then modify these relationships.l This article will thus mention the latter as well as the former.l The former two bear a close relation to a fuzzy Cartesian product.Importancel The emphasis is on an implementation of a general approach to rule based decision making.Consideration / Attentionl Careful evaluation is necessary to ensure l Such a formulation does not change further considerations.l Considerable attention has been paid tol Attention should be paid to an important finding of this investigation.l

major advantages of this new measure of xx is that it can be applied to the experimental study ofl One advantage of using a..is the ease of preparing it.l The xx system is versatilel It has a very fast decision making processl All the algorithms involve mostly logical operations.l It can be easily and without additional cost implemented in a microprocessor‑based environment.l It can reduce the waste of designing from scratch.l The advantages of using a xx to represent xx are the following:l However, xx is not without its shortcomings.l In most cases, the xxx shows an improvement over the existing xxx.l Compared to the existing xx, the impacts of the xx are generally reduced by 5% to 9%.l The “best case” results shows a savings of 6% to 9%.l Most of the existing works based on xx approach can only recognize a xx.l Most of the above methods are computational expansive and limited to xx.l Some other advantages of xx are the following:l The problem is the limitation of this method to a limited domain of parts.l It proved limited in application because it demanded precision in system modeling that was impossible in practice.l There are advantages to be gained in the structuring of costs and benefits, the use of xx, l The disadvantages of this method are also disadvantages of conventional xx approaches.l This combines the best features of both techniquesl

made above is that there are precise odds at which the expert is indifferent.l main simplifying assumptions are:l this, in our view, is a questionable assumption.outline / structure / modulel an

of the integrated system.l the model consists of four rule bases, each of which addresses a separate problem in the hierarchy of scheduling decision.l the rule bases are linked to each other in a chin‑like manner in the sense that the consequent of one rule base constitutes a part of the antecedent of the next rule base.l the rule base consists of all possible combinations of the linguistic terms associated with the linguistic variable of the antecedent of a rule.computer systeml the system has been implemented using prolog language in an ms‑dos environment.prolog was chosen because it offers a well known and flexible environment in which fuzzy reasoning may be easily implemented.l the current version of the xx program when compiled with watfor77 results in an executable code of about 270k bytes.typical run time, when run on a xx computer(an ibm compatible machine)operating at 4.77 mhz with 640k ram, ranges from 10 min to 2h, depending on the size(or complexity)of the problem.l time consuming procedures have been implemented in c‑language and directly linked to the prolog environment.l the xx process, once the xx's data has been entered, requires approximately 180 seconds.l it should be noted that the computation was done with a 20 hhz, 80386‑based microcomputer equipped with a 80387 math co‑processor.l the computer programs used for the analyses, one based on the xx method and the other based on the new method, were written in fortran with a compiler that supports the math co‑processor.l lisp, prolog give maximum flexibility but also maximizes development time.l internal representation is the way a model is represented in the computer.l an interactive menu-driven procedure is used in this studyl shell can be develop very fast at the cost of time fairly severe limitations.l while there is no measurable saving of time for the case involving five criteria, the saving is dramatic for the case involving 10 criteria--the computation time reduces from 10

zadeh suggested an inference rule named xxx(cri for short).l information is the meaningful interpretation and correlation of some aggregation of data in order to allow one to make decisions.l from a practical point of view, the computational aspects of an flc require a simplification of the fuzzy control algorithm.l the use of a hammer to insert screws, although partly effective, tends to distort, destroy, and generally defeat the purpose of using a screw [kusiak ai implications for cim p.129]justificationl we choose the so called xx in our experiment because it has received wide acceptance and canl prolog was chosen because it offers a well known and flexible environment in which fuzzy reasoning may be easily implemented.l the rationale behind this is that it can be much easier for an estimator to rate a cost as high than to attempt to place a dollar value on the estimate.l this strategy has been widely used in fuzzy control applications since it is natural and easy to implement.l a function definition expresses the membership function of a fuzzy set in a functional form, typically a bell‑shaped function, etc.such functions are used in flc because they lead themselves to manipulation through the use of fuzzy arithmetic.l it should be noted that in our daily life most of the information on which our decisions are based is linguistic rather than numerical in nature.seen in this perspective, fuzzy control rules provide a natural framework for the characterization of human behavior and decisions analysis.l many experts have found that fuzzy control rules provide a convenient way to express their domain knowledge.this explains why most flcs are based on the knowledge and experience which are expressed in the language of fuzzy “if‑the” rule.chapter 4.examplesexample/ datal the data used in the following example was taken from an experiment in which xx was measured between x and x using a xx technique.l the data consists of over xx measurements.l an example of xx is discussed and the control rules of xx are compared with a xxl examples of complex processes to which this technique may be applied are xx, xx, etc.l the following example is constructed only for the purpose of illustrating the computational procedure discussed.l this example clearly demonstrates that the profile of an inpidual xx, or a very small group of xx, with no enough data to be studied statistically, can be meaningfully analyzed by fuzzy possibilistic methods.l there is no space here to go into detail on all these methods, but deserve a mention and the bibliography will point to detailed references for those wishing this level of detail.l note that the golf ball spotting example is used throughout the paper.comparisonsl as well, the pros and cons of these representations from a process planning point of view will be discussed.l the method of using xx to implement xx described by zadeh(1973)appeared more suitablel as discussed [in the previous section]/[preciously],relationl we can not invert f' directly because it defines a many-to-one mapping.l the relationships appear very complicatel lifting tasks involve complex and imprecise

existing xxx.l compared to the existing xx, the impacts of the xx are generally reduced by 5% to 9%.l the “best case” results shows a savings of 6% to 9%.l most of the existing works based on xx

200余篇英文论文被SCI/EI收录的牛人教你如何
写英语论文
今天我很荣幸地听了唐远炎教授关于<<如何写英语论文>>的讲座,唐远炎教授在国际刊物和国际会议上发表学术论文250多篇(其中包括22本书籍,及章节), 其中 SCI检索80余篇,EI检索100余篇.听了他的讲座之后,感觉受益匪浅,有些观点和思想很有参考价值.在此想跟虫友们分享一下.通过整理,在写英语论文过程中,主要注意的有以下几点:
第一.对于初写英语论文的人来讲.最好不要对原中文论文进行直译.在谈到这个观点时,唐教授一再强调初写英语论文一定要“抄”,也就是说搜集一些类似的国外高级刊物的英语论文,在这些论文中找到要表达相似意思的英文句子,使用它的句型.这样写出来的论文更适合外国人的思维方式.也能让外国人更容易理解.同时也更容易被SCI,EI检索.他还说,按这种方式写过5篇论文左右,一些地道的英语表达方式就可以熟练的记住了.第二.在写英语论文之前,首先要确定你要投什么样的期刊.其实投中文期刊论文也是这样的.举个很简单的例子,前几天,我有一个同学,写了一篇用数学问题解决纺织工程问题的论文.导师指导他说:“如果你想投到<<纺织学报>>,在写论文时,在内容上就应该对一些数学知识作详细的说明,而纺织知识可以作粗略的介绍,但如果你想投到<<应用数学>>期刊,那就应该对纺织的一些基础知识作详细的说明!”.因此,投不同类型的期刊有不同的写作手法.这样可以提高论文的录用率.第三.要想写出被SCI/EI检索的文章一定要多花功夫在标题和摘要上.这也许是大家都知道的.外国人更注重创新,只要你觉得自己的观点有创新点,就不要怕不会被外文收录.还有一句话我还记忆忧新:“做很少人做的研究领域,做难的研究领域”.这样的文章很容易被录用.第四.中国有句古话:“熟读唐诗三百首 不会作诗也会吟.”在写英语论文之前,做大量的阅读是必要的.但最好应该去读那些英语是母语国家学者写的论文.但是,必须注意的是.无论是硕士还是博士,永远应该把专业放在第一位,英语是放在第二位.英语只是一种工具.只是一种帮助你科研的工具.第五.写英语论文时,不要使用外国人没有使用过的句型.即使这样的句子在语法上没有问题.但是外国人就是看不懂.也就相当于是一个病句.也许这种“病句”对你考CET有用,其实学英语口语也是这样的.在练英语口语时,希望虫友们记住:“讲外国人从来没说过的英语,即使语法没有问题,也是错的.”我国著名语言学家说过:“想学好一门外语,首先要学好其文化!”
以上就是我总结的一些观点.希望能对广大的虫友们有所帮助.同时希望你们能提出自己的观点.大家互相交流.实现我们共同的目标!
如果你有新的观点或对我的观点不赞同,大家一起探讨,谢谢批评指正!

通过这几天和虫友们的交流.我总结了一点新的观点.首先声明，这是真心话，希望能认真体会，能理解其中真意之后，一定就会懂的如何做研究。我老板平均每个毕业的博士都有6篇以上的SCI，他从来不强求学生发文章，只教如何做研究。下面的问题，他只和我说过一次，之后我的行动与之不相符就会被骂。现在成了习惯来这样思考，做事，发现真是事半功倍。
1.你在做研究之前，想过结果能不能发表没有？往哪里发？
2.写文章的高手是先把文章大框写好，空出数据来，等做完实验，填完空就可以发了。正谓心中有沟壑。
3.在想不清楚要写什么，要发到哪里去，自己做的与同行做的有什么出色之处，之前，就不要动手做事。去看文献，去想。想不清楚就做，不如不做 要想这样子做，就得先看文献不是？要知道如何把文章架起来，要知道别人是如何讨论的，要知道你自己的数据是不是说明了与别人不一样的东东或别人没有做过。这个过程就是看文献，想的过程，这些搞清楚了，写就简单了。要是先做事，做完发现别人做过，或无法用理论解释，岂不是冤大头？ 这可是哥们儿我被老板骂过NN次得来的血的教训啊。本来不想把这种丢人的事写出来的，可看到兄弟们好多在犯和我同样的错误，就写一下罢。但愿有用
