什么是系统工程(字幕)30

0

00:00:00,960 --> 00:00:03,640

那么有了这个结构之后

1

00:00:05,840 --> 00:00:08,660

我们就可以把行为和结构

2

00:00:08,940 --> 00:00:11,620

两个连接起来了

3

00:00:11,940 --> 00:00:13,177

那就是这一步

4

00:00:13,177 --> 00:00:15,240

就是分配行为这一步

5

00:00:16,050 --> 00:00:17,600

我们得到,把

6

00:00:18,080 --> 00:00:20,896

蒸馏器系统分成很多个块嘛

7

00:00:20,896 --> 00:00:22,070

那现在就把

8

00:00:22,350 --> 00:00:23,979

前面我们定义的行为

9

00:00:23,979 --> 00:00:25,970

你看这定义了行为,对不对

10

00:00:26,350 --> 00:00:28,340

把它分到这个块里面去

11

00:00:29,100 --> 00:00:30,900

那就用到一个什么

12

00:00:32,320 --> 00:00:33,900

分配行为的

13

00:00:34,450 --> 00:00:34,802

14

00:00:34,802 --> 00:00:36,210

这样一个

15

00:00:36,490 --> 00:00:37,610

操作

16

00:00:40,280 --> 00:00:41,390

这个图

17

00:00:42,390 --> 00:00:43,500

还是

18

00:00:44,340 --> 00:00:46,520

前面这个图,只不过怎么样

19

00:00:46,940 --> 00:00:48,750

它有这么几个变化

20

00:00:48,750 --> 00:00:51,240

第一个,这里加了几个分区

21

00:00:52,330 --> 00:00:54,940

每个分区呢,给它起了个名字

22

00:00:54,940 --> 00:00:59,507

你看,每个分区刚好映射到刚才我们的那个冷凝器

23

00:00:59,507 --> 00:01:01,465

蒸发器、排空,这个地方

24

00:01:01,465 --> 00:01:01,900

对吧

25

00:01:03,440 --> 00:01:05,600

刚好映射到这个地方

26

00:01:08,230 --> 00:01:12,210

然后这里,上面有一个构造型allocate

27

00:01:12,490 --> 00:01:14,833

也就是分配的意思

28

00:01:14,833 --> 00:01:20,040

也就是说,这里面这个加热水、冷凝蒸汽这个行为

29

00:01:21,250 --> 00:01:23,580

是分配给热交换器

30

00:01:24,990 --> 00:01:26,200

也就是说

31

00:01:26,480 --> 00:01:28,570

这是它的责任

32

00:01:29,190 --> 00:01:31,110

而这个呢,分配给它

33

00:01:31,530 --> 00:01:32,940

这个分配给它

34

00:01:33,520 --> 00:01:33,795

35

00:01:33,795 --> 00:01:34,899

这样来

36

00:01:34,899 --> 00:01:38,762

有一个分配的这样一个,行为分配

37

00:01:38,762 --> 00:01:40,693

这是第一个变化

38

00:01:40,693 --> 00:01:41,796

加了分区

39

00:01:41,796 --> 00:01:44,280

然后把行为分配分区

40

00:01:45,080 --> 00:01:49,500

而这个分区刚好是和我们刚才的

41

00:01:51,180 --> 00:01:53,900

分解那个块是对应的

42

00:01:54,560 --> 00:01:59,300

第二个变化就是,这里给每个对象流加了一个

43

00:01:59,610 --> 00:02:00,585

名字

44

00:02:00,585 --> 00:02:01,560

45

00:02:01,840 --> 00:02:04,110

of就是对象流嘛

46

00:02:04,390 --> 00:02:06,640

对象流1,对象流7,这样

47

00:02:07,850 --> 00:02:08,456

这样来

48

00:02:08,456 --> 00:02:10,480

那下面我们就来画一下

49

00:02:10,970 --> 00:02:12,870

那这个图叫什么

50

00:02:13,650 --> 00:02:15,060

包还是在

51

00:02:15,680 --> 00:02:18,850

蒸馏水的活动下面

52

00:02:20,260 --> 00:02:22,147

加了一个新的活动图

53

00:02:22,147 --> 00:02:22,567

对吧

54

00:02:22,567 --> 00:02:26,762

活动(图)叫动作已分配,或者已分配动作,都可以

55

00:02:26,762 --> 00:02:29,280

那下面我们来看一下

0

00:00:00,340 --> 00:00:02,370

那接下来呢,我们就来

1

00:00:02,650 --> 00:00:04,210

画这个分配

2

00:00:05,440 --> 00:00:07,090

活动的这个

3

00:00:08,140 --> 00:00:11,300

活动图,分配动作的活动图

4

00:00:14,340 --> 00:00:16,640

那之前那个活动图在哪里呀

5

00:00:16,980 --> 00:00:19,110

在这个需求这里

6

00:00:21,920 --> 00:00:22,610

7

00:00:24,330 --> 00:00:25,770

这个地方,对不对

8

00:00:31,650 --> 00:00:32,330

这里

9

00:00:33,700 --> 00:00:35,819

你看,经常有一些问题

10

00:00:35,819 --> 00:00:40,530

你看,这个本来这个过来应该是H2O的,对吧

11

00:00:41,290 --> 00:00:41,502

12

00:00:41,502 --> 00:00:43,630

它这里又变回来

13

00:00:43,630 --> 00:00:45,970

那我们这里重新点一下

14

00:00:48,220 --> 00:00:49,710

15

00:00:50,120 --> 00:00:51,680

重新点一下

16

00:00:52,160 --> 00:00:53,410

变回来

17

00:00:54,200 --> 00:00:56,070

包括这些地方

18

00:00:59,190 --> 00:01:02,270

那我们就直接在这上面改了

19

00:01:02,600 --> 00:01:04,010

直接在上面改

20

00:01:05,560 --> 00:01:06,197

怎么改

21

00:01:06,197 --> 00:01:07,260

我们看,首先

22

00:01:08,460 --> 00:01:11,680

把这个图的名字改成动作已分配

23

00:01:12,830 --> 00:01:13,460

24

00:01:14,640 --> 00:01:14,957

25

00:01:14,957 --> 00:01:15,910

这个图

26

00:01:18,420 --> 00:01:18,702

27

00:01:18,702 --> 00:01:19,830

图的名字

28

00:01:20,150 --> 00:01:21,658

你看,点在图这里

29

00:01:21,658 --> 00:01:25,430

本来叫再生热活动模型嘛

30

00:01:25,430 --> 00:01:27,190

我们改一下

31

00:01:27,830 --> 00:01:28,860

动作已分配

32

00:01:32,130 --> 00:01:32,366

33

00:01:32,366 --> 00:01:33,550

这是第一个

34

00:01:35,710 --> 00:01:36,640

第二个

35

00:01:37,660 --> 00:01:40,422

往上面加这个泳道了

36

00:01:40,422 --> 00:01:42,080

加这个分区

37

00:01:42,990 --> 00:01:46,400

分区之前已经加过一次了

38

00:01:46,400 --> 00:01:47,950

这里,放上来

39

00:01:51,830 --> 00:01:53,090

然后呢

40

00:01:53,860 --> 00:01:55,670

把它横过来

41

00:01:56,910 --> 00:01:57,818

竖过来吧

42

00:01:57,818 --> 00:01:58,500

应该是

43

00:01:59,410 --> 00:01:59,700

44

00:01:59,700 --> 00:02:01,440

这是一个分区

45

00:02:02,010 --> 00:02:02,685

然后呢

46

00:02:02,685 --> 00:02:03,810

这个分区呢

47

00:02:03,810 --> 00:02:04,260

它是

48

00:02:04,760 --> 00:02:06,230

冷凝器:热交换器

49

00:02:06,230 --> 00:02:07,490

那我们就把它

50

00:02:11,600 --> 00:02:13,690

它这个类元

51

00:02:14,670 --> 00:02:17,590

设成这个冷凝器:热交换器

52

00:02:18,700 --> 00:02:19,585

在哪里

53

00:02:19,585 --> 00:02:21,576

在那个结构这里嘛

54

00:02:21,576 --> 00:02:24,010

看看结构的那个block叫什么

55

00:02:24,480 --> 00:02:26,520

热交换器,这里

56

00:02:28,530 --> 00:02:29,560

这地方

57

00:02:29,840 --> 00:02:30,246

58

00:02:30,246 --> 00:02:31,870

热交换器

59

00:02:35,190 --> 00:02:36,330

然后呢

60

00:02:37,020 --> 00:02:38,270

这个名字

61

00:02:38,970 --> 00:02:41,897

你看,这个类元叫热交换器

62

00:02:41,897 --> 00:02:43,570

这个名字就叫什么

63

00:02:44,440 --> 00:02:45,830

64

00:02:48,040 --> 00:02:49,620

冷凝器

65

00:02:53,880 --> 00:02:54,650

对吧

66

00:02:54,930 --> 00:02:56,050

这样来

67

00:02:56,380 --> 00:02:58,590

然后,我们看这个图

68

00:02:59,070 --> 00:03:00,300

这个过来一点

69

00:03:00,300 --> 00:03:01,530

这两个对着的

70

00:03:04,140 --> 00:03:05,190

那我们

71

00:03:06,350 --> 00:03:09,170

这个图,一直画到下面来

72

00:03:11,890 --> 00:03:12,121

73

00:03:12,121 --> 00:03:13,510

这个过来一点

74

00:03:15,050 --> 00:03:15,930

对一对

75

00:03:17,420 --> 00:03:18,450

上一点

76

00:03:20,740 --> 00:03:21,000

77

00:03:21,000 --> 00:03:21,520

78

00:03:26,230 --> 00:03:27,061

冷凝器

79

00:03:27,061 --> 00:03:28,170

热交换器

80

00:03:37,450 --> 00:03:39,490

接下来,下一个就是

81

00:03:40,540 --> 00:03:41,318

这个了

82

00:03:41,318 --> 00:03:42,680

这个有个构造型

83

00:03:44,410 --> 00:03:44,682

84

00:03:44,682 --> 00:03:45,770

加上去

85

00:03:46,650 --> 00:03:48,390

选中这个

86

00:03:48,670 --> 00:03:50,520

然后这里有构造型

87

00:03:52,940 --> 00:03:55,510

找到那个SysML

88

00:03:59,120 --> 00:03:59,850

这个

89

00:04:00,520 --> 00:04:01,430

选上

90

00:04:02,820 --> 00:04:03,088

91

00:04:03,088 --> 00:04:04,162

有了,对吧

92

00:04:04,162 --> 00:04:04,700

你看

93

00:04:06,730 --> 00:04:07,730

对上了

94

00:04:14,150 --> 00:04:16,080

那就相当于把这个

95

00:04:17,070 --> 00:04:17,362

96

00:04:17,362 --> 00:04:19,120

我们看这个

97

00:04:19,400 --> 00:04:21,406

把它挪一下位置

98

00:04:21,406 --> 00:04:23,126

这是蒸汽过来

99

00:04:23,126 --> 00:04:23,986

这是热

100

00:04:23,986 --> 00:04:24,560

对吧

101

00:04:24,560 --> 00:04:24,846

102

00:04:24,846 --> 00:04:25,420

蒸汽

103

00:04:25,770 --> 00:04:28,070

热在这边

104

00:04:29,200 --> 00:04:30,220

过来一点

105

00:04:34,660 --> 00:04:35,310

这样

106

00:04:44,630 --> 00:04:44,844

107

00:04:44,844 --> 00:04:46,770

把它变成直的

108

00:04:55,680 --> 00:04:56,350

109

00:04:56,630 --> 00:04:58,590

110

00:05:00,010 --> 00:05:01,080

111

00:05:06,100 --> 00:05:07,450

一会再搞

112

00:05:07,970 --> 00:05:10,450

热这里,蒸汽这样过来

113

00:05:15,850 --> 00:05:16,055

114

00:05:16,055 --> 00:05:17,290

我们看下一个

115

00:05:19,510 --> 00:05:20,960

下一个是什么

116

00:05:21,960 --> 00:05:23,653

煮沸器、阀门

117

00:05:23,653 --> 00:05:24,500

同样

118

00:05:26,330 --> 00:05:27,360

放上来

119

00:05:34,660 --> 00:05:36,710

类元,煮沸器

120

00:05:40,560 --> 00:05:43,660

名字叫做蒸发器

121

00:05:50,660 --> 00:05:52,340

然后这里同样的

122

00:05:54,110 --> 00:05:55,231

又变回来了

123

00:05:55,231 --> 00:05:55,680

哎呀

124

00:06:00,370 --> 00:06:01,200

125

00:06:10,190 --> 00:06:11,180

过来

126

00:06:13,450 --> 00:06:14,260

127

00:06:14,540 --> 00:06:15,490

再来一个

128

00:06:37,110 --> 00:06:38,830

名字是排空

129

00:07:07,000 --> 00:07:08,590

好,齐了没有

130

00:07:09,690 --> 00:07:10,120

131

00:07:10,120 --> 00:07:10,980

齐了

132

00:07:12,110 --> 00:07:16,738

然后,接下来就是给这个对象流标个号

133

00:07:16,738 --> 00:07:18,100

of1,of2

134

00:07:22,550 --> 00:07:23,850

这个叫

135

00:07:24,250 --> 00:07:25,720

of1

136

00:07:37,080 --> 00:07:37,472

137

00:07:37,472 --> 00:07:41,000

这个是of8,of3

138

00:07:48,780 --> 00:07:49,025

139

00:07:49,025 --> 00:07:52,958

这个应该放中间才对的,往这边靠

140

00:07:52,958 --> 00:07:53,696

那不对

141

00:07:53,696 --> 00:07:54,925

142

00:07:54,925 --> 00:07:56,400

放中间才对

143

00:08:07,740 --> 00:08:08,223

144

00:08:08,223 --> 00:08:09,190

of3

145

00:08:11,190 --> 00:08:12,270

还有什么

146

00:08:13,240 --> 00:08:15,320

2,5,6

147

00:08:47,190 --> 00:08:47,548

148

00:08:47,548 --> 00:08:48,980

还有什么

149
