A considerable amount of research has been done .. during the last decade 25. A great number of studies report on the treatment of uncertainties associated with xx. 26. There is considerable amount of literature on planning 27. However, these studies do not provide much attention to uncertainty in xx. 28. Since then, the subject has been extensively explored and it is still under investigation as well in methodological aspects as in concrete applications. 29. Many research studies have been carried out on this topic. 30. Problem of xx draws recently more and more attention of system analysis. 31. Attempts to resolve this dilemma have resulted in the development of 32. Many plex processes unfortunately, do not yield to this design procedure and have, therefore, not yet been automated. 33. Most of the methods developed so far are deterministic and /or probabilistic in nature. 34. The central issue in all these studies is to 35. The problem of xx has been studied by other investigators, however, these studies have been based upon classical statistical approaches. 36. Applied ... techniques to 37. Characterized the ... system as 38. Developed an algorithm to 39. Developed a system called ... which 40. Uses an iterative algorithm to deduce 41. Emphasized the need to 42. Identifies six key issues surrounding high technology 43. A prehensive study of the... has been undertaken 44. Much work has been reported recently in these filed 45. Proposed/Presented/State that/Described/Illustrated/ Indicated/Has shown / showed/Address/Highlights 46. Point out that the problem of 47. A study on ...was done / developed by [] 48. Previous work, such as [] and [], deal only with 49. The approach taken by [] is 50. The system developed by [] consists 51. A paper relevant to this research was published by [] 52. []39。 s model requires consideration of... 53. []39。 model draws attention to evolution in human development 54. []39。 s model focuses on... 55. Little research has been conducted in applying ... to 56. The published information that is relevant to this research... 57. This study further shows that 58. Their work is based on the principle of 59. More history of ... can be found in xx et al. [1979]. 60. Studies have been pleted to established 61. The ...studies indicated that 62. Though application of xx in the filed of xx has proliferated in recent years, effort in analyzing xx, especially xx, is lacking. Problem / Issue / Question 63. Unfortunately, realworld engineering problems such as manufacturing planning do not fit well with this narrowly defined model. They tend to span broad activities and require consideration of multiple aspects. 64. Remedy / solve / alleviate these problems 67. ... is a difficult problem, yet to be adequately resolved 68. Two major problems have yet to be addressed 69. An unanswered question 70. This problem in essence involves using x to obtain a solution. 71. An additional research issue to be tackled is .... 72. Some important issues in developing a ... system are discussed 73. The three prime issues can be summarized: 74. The situation leads to the problem of how to determine the ... 75. There have been many attempts to 76. It is expected to be serious barrier to 77. It offers a simple solution in a limited domain for a plex problem. 1. There are several ways to get around this problem. 2. As difficult as it seems to be, xx is by no means new. 3. The problem is to recognize xx from a design representation. 4. A xx problem can trace its roots to xx. 5. xx [1987] used a heuristic approach to simplify the plexity of the problem. 6. Several problems are associated with them. 7. Although some progress has been made in this area, at least two major obstacles must be overe before a fully automated system can be realized. 8. Most problems in practice are plicated 9. More problem surface here. 10. Hamper effort toward a xx system 11. In order to overe the limitations due to inplete and imprecise xx knowledge, a xx program has been developed, which bases its knowledge upon the statistical analysis of a sample population of xx 12. The above difficulties are real challenges faced by researchers attempting to develop 13. This type of mapping raises no controversy to the issue of membership function determination. 14. However, attempts to quantify the xx have met both theoretical and empirical problems. 15. It has bee apparent that in order to apply this new methodological framework to realworld problems and data, we have to pay attention to the problems of xx and xx. 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, . given by a fuzzy set in the space of control stages, may be applied. 2. We assume here the fuzzy constraints to be statedependent, and。
