09、Chapter 3. Proposed methodology
Assumption
1. In the case when 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.
2. 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.
3. 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.
4. Another assumption made above is that there are precise odds at which the expert is indifferent.
5. Main simplifying assumptions are:
6. This, in our view, is a questionable assumption.
Outline / Structure / Module

5. Can be broadly classified into the following areas:
l Can be characterized by its function of effectively processing the
l Can allow further breadth of application of ...into more
l The following steps should be followed
l xx can be classified by a different ways.
l Based on the xx, one may classify xx into the following:
l This catalog may change due to wear, breakage, and purchasing.
System
l Unlike many conventional program, expert systems do not usually deal wit
h problem for which there is clearly a right or wrong answer.
l The system consists of both ... and ...
l The system has a hierarchical modular architecture organized on three levels.
l expert system domains are area of expertise
l To develop a xx system for xx, the following factors must be considered:
l The system has been developed / designed to determine

l An interactive automatic ... system
l A .. is commonly thought of as a truly integrated .. system
l Should be capable of being generated from a ... system
l xx is an important part 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 System
l 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 from10 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, 80386209;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 study
l 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.

l For manufacturing purposes, a detailed and precise model of the object is necessary
l 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 View
l 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]
Justification
l We choose the so called xx in our experiment because it has received wide acceptance and can
l 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.
010、Chapter 4. Examples
Example/ Data
l 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 ofover xx measurements.
l An example of xx is discussed and the control rules of xx are compared with a xx
l 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 individual 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.
Comparisons
l 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 suitable
l As discussed [in the previous section]/[preciously],
Relation
l We can not invert F' directly because it defines a many-to-one mapping.
l The relationships appear very complicate
l 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.
Importance
