0
00:00:00,670 –> 00:00:01,582
如果不加图
1
00:00:01,582 –> 00:00:02,130
怎么加
2
00:00:02,130 –> 00:00:03,225
我们来看一下
3
00:00:03,225 –> 00:00:03,590
你看
4
00:00:03,980 –> 00:00:06,720
右键点这个，添加元素
5
00:00:07,380 –> 00:00:07,960
6
00:00:08,500 –> 00:00:09,800
这里选
7
00:00:10,400 –> 00:00:13,100
系统工程，SysML
8
00:00:13,480 –> 00:00:13,781
9
00:00:13,781 –> 00:00:17,700
然后SysML 1.5，块定义
10
00:00:18,000 –> 00:00:18,167
11
00:00:18,167 –> 00:00:20,005
这里默认就已经是block了
12
00:00:20,005 –> 00:00:22,010
那我们首先加第一个是什么
13
00:00:22,860 –> 00:00:23,620
这个
14
00:00:27,300 –> 00:00:29,150
蒸馏器系统上下文
15
00:00:30,570 –> 00:00:33,820
直接敲蒸馏器系统
16
00:00:34,540 –> 00:00:35,920
上下文
17
00:00:39,420 –> 00:00:41,080
你看，这就多了一个
18
00:00:41,080 –> 00:00:41,495
对吧
19
00:00:41,495 –> 00:00:42,948
然后可以继续加
20
00:00:42,948 –> 00:00:44,608
你看那个界面还在
21
00:00:44,608 –> 00:00:45,231
对不对
22
00:00:45,231 –> 00:00:47,722
我们一个一个加，水源，蒸馏器
23
00:00:47,722 –> 00:00:49,174
水分配系统，热源
24
00:00:49,174 –> 00:00:49,590
对吧
25
00:00:50,270 –> 00:00:52,420
水源
26
00:00:56,010 –> 00:00:57,390
蒸馏器
27
00:00:59,320 –> 00:01:02,160
水分配系统
28
00:01:08,830 –> 00:01:10,130
热源
29
00:01:12,970 –> 00:01:13,220
好
30
00:01:13,220 –> 00:01:13,970
还有吗
31
00:01:13,970 –> 00:01:14,720
我看看
32
00:01:15,520 –> 00:01:17,100
33
00:01:17,730 –> 00:01:18,078
34
00:01:18,078 –> 00:01:19,470
就这几个
35
00:01:20,060 –> 00:01:20,392
好
36
00:01:20,392 –> 00:01:23,720
这是这几个结点上那个bloc服务器托管网k了
37
00:01:24,020 –> 00:01:28,291
也就是说，结点上这个block每个代表一个什么
38
00:01:28,291 –> 00:01:29,640
代表一个系统
39
00:01:29,640 –> 00:01:30,090
对吧
40
00:01:30,370 –> 00:01:31,470
所以这个
41
00:01:32,140 –> 00:01:36,136
块内部图的抽象级别是在什么级别
42
00:01:36,136 –> 00:01:39,910
它是系统之间的交互
43
00:01:44,340 –> 00:01:44,654
好
44
00:01:44,654 –> 00:01:45,910
这里没了
45
00:01:47,070 –> 00:01:50,190
那接下来，就来加这个了
46
00:01:50,650 –> 00:01:52,630
中间这个流动
47
00:01:52,630 –> 00:01:53,950
这个热、水
48
00:01:53,950 –> 00:01:54,610
这个
49
00:01:56,280 –> 00:01:58,772
你看，这后面是类
50
00:01:58,772 –> 00:02:01,014
这后面是那个类
51
00:02:01,014 –> 00:02:02,510
或者类元，这是那个
52
00:02:03,060 –> 00:02:05,028
实例的名字，对吧
53
00:02:05,028 –> 00:02:05,310
54
00:02:05,310 –> 00:02:07,278
冒号右边是类型
55
00:02:07,278 –> 00:02:08,403
左边实例
56
00:02:08,403 –> 00:02:09,810
所以我们是
57
00:02:10,130 –> 00:02:10,990
先
58
00:02:11,490 –> 00:02:12,595
加这个类型
59
00:02:12,595 –> 00:02:13,921
一个水，一个热
60
00:02:13,921 –> 00:02:15,911
后面什么污水净水呀
61
00:02:15,911 –> 00:02:17,680
这个是它的那个
62
00:02:18,190 –> 00:02服务器托管网:19,670
实例的名字
63
00:02:19,950 –> 00:02:22,250
或者说，角色的名字
64
00:02:24,050 –> 00:02:24,997
加在哪里
65
00:02:24,997 –> 00:02:27,130
那这个是放在值类型
66
00:02:28,670 –> 00:02:30,390
这个包这里
67
00:02:32,440 –> 00:02:33,890
这里我们可以
68
00:02:35,000 –> 00:02:37,153
添加两个block，一样的
69
00:02:37,153 –> 00:02:38,349
跟刚才一样
70
00:02:38,349 –> 00:02:40,742
你可以不用画图都可以
71
00:02:40,742 –> 00:02:40,981
72
00:02:40,981 –> 00:02:41,460
添加
73
00:02:41,740 –> 00:02:42,790
一个是
74
00:02:43,070 –> 00:02:44,020
水
75
00:02:49,420 –> 00:02:50,620
一个是热
76
00:02:54,770 –> 00:02:55,570
好
77
00:02:56,470 –> 00:02:57,790
这两个有了
78
00:03:01,690 –> 00:03:03,190
那接下来
79
00:03:03,900 –> 00:03:05,793
就是要画这个图了
80
00:03:05,793 –> 00:03:07,450
你看，这个图是什么
81
00:03:08,420 –> 00:03:13,470
这个蒸馏器系统上下文这个block的什么
82
00:03:13,750 –> 00:03:16,570
IBD，就是内部块图
83
00:03:17,790 –> 00:03:19,050
它名字叫
84
00:03:19,630 –> 00:03:21,650
context，上下文
85
00:03:22,400 –> 00:03:23,240
这是它的名字
86
00:03:23,240 –> 00:03:24,753
那我们就来画一下
87
00:03:24,753 –> 00:03:25,090
你看
88
00:03:26,110 –> 00:03:28,570
针对这个上下文
89
00:03:29,220 –> 00:03:30,048
画图嘛
90
00:03:30,048 –> 00:03:31,430
右键点它
91
00:03:31,970 –> 00:03:34,040
添加一个这个
92
00:03:35,180 –> 00:03:35,860
对吧
93
00:03:36,140 –> 00:03:37,270
添加这个
94
00:03:38,460 –> 00:03:38,756
95
00:03:38,756 –> 00:03:40,830
图的名字，上下文
96
00:03:44,360 –> 00:03:45,812
怎么1.4
97
00:03:45,812 –> 00:03:47,103
我们不要1.4
98
00:03:47,103 –> 00:03:47,910
我们1.5
99
00:03:48,230 –> 00:03:49,310
添加
100
00:03:49,880 –> 00:03:51,530
添加图
101
00:03:51,870 –> 00:03:53,070
然后呢
102
00:03:53,070 –> 00:03:53,870
这个
103
00:03:56,060 –> 00:03:57,320
SysML
104
00:03:57,910 –> 00:03:58,900
1.5
105
00:03:59,560 –> 00:04:00,180
106
00:04:01,230 –> 00:04:02,030
这个
107
00:04:02,470 –> 00:04:04,370
然后改名叫上下文
108
00:04:07,890 –> 00:04:08,157
好
109
00:04:08,157 –> 00:04:10,560
你看，对应一下这个
110
00:04:11,570 –> 00:04:13,410
IBD block
111
00:04:13,850 –> 00:04:15,930
蒸馏器系统上下文，上下文
112
00:04:16,760 –> 00:04:20,113
IBD block，蒸馏器系统上下文
113
00:04:20,113 –> 00:04:20,831
对吧
114
00:04:20,831 –> 00:04:21,310
好
115
00:04:21,310 –> 00:04:21,790
接下来，我们就要来
116
00:04:23,830 –> 00:04:25,020
把这些
117
00:04:25,790 –> 00:04:27,210
放上去了
118
00:04:27,720 –> 00:04:29,740
那这些浏览器里都有了嘛
119
00:04:29,740 –> 00:04:30,144
对吧
120
00:04:30,144 –> 00:04:31,760
我们就把它拖上来
121
00:04:35,010 –> 00:04:36,270
第一个要拖的
122
00:04:36,270 –> 00:04:37,110
就是那个
123
00:04:38,140 –> 00:04:39,170
水源
124
00:04:39,530 –> 00:04:41,340
这里，拖上来
125
00:04:42,990 –> 00:04:47,269
然后这里选property，表示这是它的一个属性
126
00:04:47,269 –> 00:04:49,623
它默认就property，属性
127
00:04:49,623 –> 00:04:51,120
还有其他选项
128
00:04:51,120 –> 00:04:52,618
先不用管它
129
00:04:52,618 –> 00:04:54,116
就这个，属性
130
00:04:54,116 –> 00:04:55,186
实际上这一步
131
00:04:55,186 –> 00:04:56,470
跟我们在那个
132
00:04:57,750 –> 00:05:00,454
块定义图里面画那个组合关系
133
00:05:00,454 –> 00:05:01,910
是一样的
134
00:05:02,190 –> 00:05:04,836
只不过我们这里没有画那个块定义图组合关系
135
00:05:04,836 –> 00:05:06,160
如果你画了组合关系
136
00:05:07,020 –> 00:05:10,240
说我这个上下文组合了一个水源
137
00:05:10,900 –> 00:05:12,100
那么这个
138
00:05:12,510 –> 00:05:15,995
上下文这里，你看，这里就出现一个属性嘛
139
00:05:15,995 –> 00:05:16,815
你看
140
00:05:16,815 –> 00:05:17,020
141
00:05:17,020 –> 00:05:20,095
你在块定义图里面画一个组合关系
142
00:05:20,095 –> 00:05:22,145
它也可以起到这个效果
143
00:05:22,145 –> 00:05:23,990
它也是一个属性
144
00:05:24,560 –> 00:05:26,786
因为我没有画块定义图嘛
145
00:05:26,786 –> 00:05:28,608
我们直接在块内部图
146
00:05:28,608 –> 00:05:31,240
内部块图这里操作了
147
00:05:32,270 –> 00:05:35,299
所以这里，那这个名字就不要了
148
00:05:35,299 –> 00:05:36,380
这名字不要
149
00:05:36,380 –> 00:05:37,030
因为它
150
00:05:39,350 –> 00:05:41,937
那个图上这里就没有名字嘛
151
00:05:41,937 –> 00:05:42,335
对吧
152
00:05:42,335 –> 00:05:43,530
这里没有名字
153
00:05:43,990 –> 00:05:47,040
左边这个实例名没有
154
00:05:47,440 –> 00:05:50,820
还有，接下来，下一个就是那个蒸馏器
155
00:05:55,620 –> 00:05:57,300
也同样不要名字
156
00:05:59,620 –> 00:06:00,630
还有什么
157
00:06:01,350 –> 00:06:02,670
水分配系统
158
00:06:12,110 –> 00:06:13,865
还有操作人员
159
00:06:13,865 –> 00:06:16,280
那从用例那里拖过来了
160
00:06:16,600 –> 00:06:17,420
放这里
161
00:06:26,380 –> 00:06:28,670
还有什么，热源
162
00:06:39,530 –> 00:06:43,100
还有一个小人是用水人员
163
00:06:50,970 –> 00:06:52,070
这样
164
00:06:52,350 –> 00:06:54,150
我们对齐一下
165
00:07:09,700 –> 00:07:10,730
小一点
166
00:07:11,530 –> 00:07:11,822
好
167
00:07:11,822 –> 00:07:12,990
往下一点
168
00:07:48,280 –> 00:07:49,220
好
169
00:07:50,080 –> 00:07:51,130
这样来
170
00:07:52,000 –> 00:07:55,290
那接下来，你看，这里有一个
171
00:07:55,850 –> 00:07:56,793
多重性
172
00:07:56,793 –> 00:07:59,386
表示这个属性的多重性
173
00:07:59,386 –> 00:08:00,330
这个得先
174
00:08:00,820 –> 00:08:02,100
设置了
175
00:08:04,390 –> 00:08:05,201
那多重性在哪里设置
176
00:08:05,201 –> 00:08:07,230
就选中这个
177
00:08:09,170 –> 00:08:12,010
然后在property这里
178
00:08:12,410 –> 00:08:13,090
179
00:08:13,630 –> 00:08:14,945
然后往下走
180
00:08:14,945 –> 00:08:16,260
你看有多重性
181
00:08:17,930 –> 00:08:20,094
然后这个是多少来着
182
00:08:20,094 –> 00:08:21,297
一到多，对吧
183
00:08:21,297 –> 00:08:22,740
所以下限是1
184
00:08:23,190 –> 00:08:24,820
上限是多
185
00:08:27,650 –> 00:08:28,270
186
00:08:29,340 –> 00:08:29,583
187
00:08:29,583 –> 00:08:31,528
你看，这就出来了
188
00:08:31,528 –> 00:08:33,230
这个呢，是多少
189
00:08:33,510 –> 00:08:36,750
这是0到多
190
00:08:37,740 –> 00:08:39,195
下限是0
191
00:08:39,195 –> 00:08:40,650
上限是多
192
00:08:42,880 –> 00:08:43,154
193
00:08:43,154 –> 00:08:44,250
这样来
194
00:08:44,880 –> 00:08:46,005
搞小一点
195
00:08:46,005 –> 00:08:47,580
这个太大了
196
00:08:57,930 –> 00:08:59,150
下面也是一样
197
00:08:59,860 –> 00:09:00,061
198
00:09:00,061 –> 00:09:01,070
都搞小一点
199
00:09:12,430 –> 00:09:12,846
好
200
00:09:12,846 –> 00:09:14,510
这搞定了
201
00:09:15,310 –> 00:09:17,355
但是这里有个小人
202
00:09:17,355 –> 00:09:19,401
这个就搞不定了
203
00:09:19,401 –> 00:09:20,310
这搞不定
204
00:09:20,310 –> 00:09:21,220
因为那个
205
00:09:21,710 –> 00:09:22,801
这里没有小人
206
00:09:22,801 –> 00:09:24,257
你要小人可以
207
00:09:24,257 –> 00:09:25,531
你把小人拖上来
208
00:09:25,531 –> 00:09:26,440
你看怎么做
209
00:09:26,440 –> 00:09:28,260
如果你不想要这个
210
00:09:28,260 –> 00:09:29,534
你想要小人呢
211
00:09:29,534 –> 00:09:30,080
拖上来
212
00:09:30,520 –> 00:09:30,723
213
00:09:30,723 –> 00:09:33,159
但这里就不要Property了
214
00:09:33,159 –> 00:09:34,580
这里选实例
215
00:09:34,940 –> 00:09:35,670
这里
216
00:09:36,740 –> 00:09:37,836
这样可以
217
00:09:37,836 –> 00:09:39,590
但是这样可以的话
218
00:09:39,590 –> 00:09:42,880
这边就没有这个方框了
219
00:09:44,260 –> 00:09:47,460
所以我们这里，这小人就不管它了
220
00:09:51,410 –> 00:09:51,686
好
221
00:09:51,686 –> 00:09:53,900
接下来呢，就是轮到
222
00:09:54,630 –> 00:09:57,750
各个block之间的那个
223
00:09:58,590 –> 00:10:01,140
应该说各个属性之间的那个
224
00:10:01,750 –> 00:10:02,630
关系了
225
00:10:02,630 –> 00:10:03,510
那个连接
226
00:10:03,510 –> 00:10:06,810
那这里面的连接，实际上就一个，就是那个
227
00:10:08,750 –> 00:10:14,981
项，item的这个流，item这个流的关系
228
00:10:14,981 –> 00:10:17,813
实际上是一种动态的关系
229
00:10:17,813 –> 00:10:18,380
我有
230
00:10:19,140 –> 00:10:20,910
水流到你那里
231
00:10:22,700 –> 00:10:24,130
那这个怎么画
232
00:10:25,310 –> 00:10:28,047
我们的那个水、热是在哪里
233
00:10:28,047 –> 00:10:29,415
水、热在这里嘛
234
00:10:29,415 –> 00:10:29,871
对吧
235
00:10:29,871 –> 00:10:30,100
236
00:10:32,430 –> 00:10:33,673
然后画过来
237
00:10:33,673 –> 00:10:37,653
显然这个三角这个，就是哪一个
238
00:10:37,653 –> 00:10:38,400
就这个
239
00:10:39,390 –> 00:10:43,010
项流这个，你看怎么画
240
00:10:43,010 –> 00:10:44,820
选中这个，画过来
241
00:10:46,150 –> 00:10:46,800
242
00:10:47,080 –> 00:10:48,520
然后添加
243
00:10:48,960 –> 00:10:50,588
我们是水嘛
244
00:10:50,588 –> 00:10:51,240
对吧
245
00:10:51,950 –> 00:10:52,770
确定
246
00:10:53,170 –> 00:10:54,920
然后这里添加上这个
247
00:10:58,370 –> 00:10:58,598
好
248
00:10:58,598 –> 00:10:59,738
这样过来
249
00:10:59,738 –> 00:11:01,334
我把它过来一点
250
00:11:01,334 –> 00:11:01,562
251
00:11:01,562 –> 00:11:02,930
有点窄了
252
00:11:06,850 –> 00:11:07,152
好
253
00:11:07,152 –> 00:11:08,060
接下来
254
00:11:09,900 –> 00:11:14,340
但是这个跟我们这个图上不是一致的哦
255
00:11:15,660 –> 00:11:17,809
图上是说，你看，水是水
256
00:11:17,809 –> 00:11:19,720
它前面有个说脏水
257
00:11:20,290 –> 00:11:20,658
258
00:11:20,658 –> 00:11:22,500
也就是说，水
259
00:11:24,610 –> 00:11:25,640
是一个
260
00:11:26,000 –> 00:11:27,020
大的类型
261
00:11:27,020 –> 00:11:29,060
下面又分脏水
262
00:11:29,530 –> 00:11:30,550
净水
263
00:11:31,710 –> 00:11:33,780
那这个脏水怎么表达
264
00:11:34,570 –> 00:11:34,751
265
00:11:34,751 –> 00:11:36,925
不可能说我把水改成冒号
266
00:11:36,925 –> 00:11:37,830
这不行
267
00:11:37,830 –> 00:11:39,280
另外一种就是什么
268
00:11:39,890 –> 00:11:44,330
一种做法是在这上面添加一个污水的
269
00:11:45,690 –> 00:11:46,530
Block
270
00:11:46,890 –> 00:11:49,950
它是这个水的一个
271
00:11:50,780 –> 00:11:52,470
子类
272
00:11:52,750 –> 00:11:55,420
或者子block，一个泛化关系
273
00:11:56,720 –> 00:11:56,888
274
00:11:56,888 –> 00:11:58,574
污水去继承这个水
275
00:11:58,574 –> 00:12:00,260
但这里说的不是继承
276
00:12:00,260 –> 00:12:02,790
而是说什么，冒号说的是一个实例
