130
00:07:05,080 --> 00:07:06,680
这是历史

131
00:07:06,680 --> 00:07:11,400
那么在这个过程中

132
00:07:11,400 --> 00:07:14,840
就会出现多种变体了

133
00:07:14,840 --> 00:07:15,560
一个变体

134
00:07:15,560 --> 00:07:16,640
就是BPMN

135
00:07:16,640 --> 00:07:20,360
就是描述BP嘛

136
00:07:20,360 --> 00:07:21,480
业务流程嘛

137
00:07:21,480 --> 00:07:24,320
业务流程的那个表示法

138
00:07:24,320 --> 00:07:28,440
实际上就是跟活动图差不多的

139
00:07:28,440 --> 00:07:31,120
但是呢

140
00:07:31,120 --> 00:07:34,320
看起来比活动图要漂亮

141
00:07:34,320 --> 00:07:36,960
加颜色还有各种图标等等

142
00:07:36,960 --> 00:07:40,000
那么这是

143
00:07:40,000 --> 00:07:45,120
我画的一个BPMN示范的一个图

144
00:07:45,120 --> 00:07:47,400
这个图怎么画的

145
00:07:47,400 --> 00:07:48,960
BPMN这个

146
00:07:48,960 --> 00:07:51,960
大家可以看我们UMLChina的视频号

147
00:07:51,960 --> 00:07:54,160
上面有这个建模的操作示范

148
00:07:54,160 --> 00:07:57,320
感兴趣

149
00:07:57,320 --> 00:08:00,320
可以去看那个示范

150
00:08:00,320 --> 00:08:01,320
照着做就行了

151
00:08:03,760 --> 00:08:05,760
另外一个变体就是

152
00:08:05,760 --> 00:08:07,200
ArchiMate

153
00:08:07,200 --> 00:08:12,640
ArchiMate这个是

154
00:08:12,640 --> 00:08:16,760
另外一种描述，也是

155
00:08:16,760 --> 00:08:19,440
像UML一样

156
00:08:19,440 --> 00:08:22,120
另外一种表示法

157
00:08:22,120 --> 00:08:25,400
它里面描述业务流程的

158
00:08:25,400 --> 00:08:28,400
EA也同样

159
00:08:28,400 --> 00:08:30,200
这是EA给出的

160
00:08:30,200 --> 00:08:31,640
ArchiMate的

161
00:08:32,960 --> 00:08:34,120
示范的那个图

162
00:08:34,120 --> 00:08:36,840
EA里面也可以画

163
00:08:36,840 --> 00:08:42,040
但是呢

164
00:08:42,040 --> 00:08:43,400
我们建议的话

165
00:08:43,400 --> 00:08:47,440
优先还是要先学习这个活动图

166
00:08:47,440 --> 00:08:50,480
原因

167
00:08:50,480 --> 00:08:52,200
主要是两点，刚才讲了

168
00:08:52,200 --> 00:08:55,360
活动图应用范围更广

169
00:08:55,360 --> 00:08:58,880
它没有绑定任何的

170
00:08:58,880 --> 00:09:01,520
你看，那个BPMN也好么

171
00:09:01,520 --> 00:09:02,160
ArchiMate也好

172
00:09:02,160 --> 00:09:03,680
你看，背后就是什么

173
00:09:03,680 --> 00:09:05,240
企业架构

174
00:09:05,240 --> 00:09:07,520
企业流程之类的

175
00:09:07,520 --> 00:09:09,240
你看都说企业什么什么

176
00:09:09,240 --> 00:09:10,160
企业什么

177
00:09:10,160 --> 00:09:12,440
都把它

178
00:09:12,440 --> 00:09:14,280
定在那里了

179
00:09:14,280 --> 00:09:15,280
带上

180
00:09:15,280 --> 00:09:16,640
染上这个颜色了

181
00:09:16,640 --> 00:09:19,360
活动图没有说企业什么什么

182
00:09:19,360 --> 00:09:20,840
你可以描述企业

183
00:09:20,840 --> 00:09:21,520
可以描述

190
00:09:33,400 --> 00:09:34,200
有的是什么

191
00:09:34,200 --> 00:09:35,320
因为现在很多系统

192
00:09:35,320 --> 00:09:39,280
它不只是信息的

193
00:09:39,280 --> 00:09:50,000
处理

194
00:09:50,000 --> 00:09:51,440
软件是处理信息的

195
00:09:51,440 --> 00:09:52,840
信息进来

196
00:09:52,840 --> 00:09:53,640
信息出去

197
00:09:53,640 --> 00:09:55,200
但是呢

198
00:09:55,200 --> 00:09:57,880
如果你要把能量的处理

199
00:09:57,880 --> 00:10:00,040
物质的处理

200
00:10:00,880 --> 00:10:02,560
也包括进来的话

201
00:10:02,560 --> 00:10:03,000
那么

202
00:10:03,000 --> 00:10:05,800
就要用SysML来描述

203
00:10:05,800 --> 00:10:08,400
SysML里面

204
00:10:08,400 --> 00:10:11,360
是支持活动图的

205
00:10:11,360 --> 00:10:13,360
当然SysML2已经把活动图

206
00:10:13,360 --> 00:10:16,640
的活动去掉了

207
00:10:16,640 --> 00:10:18,480
做了一个大的裁减

208
00:10:18,480 --> 00:10:21,640
把一些乱七八糟的词

209
00:10:21,640 --> 00:10:22,480
全部删掉了

210
00:10:22,480 --> 00:10:25,160
全部变成什么

211
00:10:25,160 --> 00:10:26,640
部件，部件定义

212
00:10:26,640 --> 00:10:27,840
端口，端口定义

213
00:10:27,840 --> 00:10:29,560
属性，属性定义，变成这样了

214
00:10:30,000 --> 00:10:33,920
以前这些乱七八糟的造词全部删掉

215
00:10:33,920 --> 00:10:35,720
这是一个很好的做法

216
00:10:35,720 --> 00:10:39,400
本来它们就是这样的一个关系

217
00:10:39,400 --> 00:10:41,800
结果又造出一些词来

218
00:10:41,800 --> 00:10:45,040
搞得大家又要重新解释一遍

219
00:10:45,040 --> 00:10:46,240
没有必要

220
00:10:46,240 --> 00:10:46,680
就直接

221
00:10:46,680 --> 00:10:47,000
你看

222
00:10:47,000 --> 00:10:48,440
对应下来

223
00:10:48,440 --> 00:10:51,360
那活动就变成了什么

224
00:10:51,360 --> 00:10:52,600
动作的定义了

225
00:10:52,600 --> 00:10:56,680
动作就变成活动的实例

226
00:10:56,680 --> 00:10:58,040
动作，动作定义

227
00:10:58,040 --> 00:11:00,640
或者动作规格

228
00:11:00,640 --> 00:11:02,360
这个后面我们还会再讲

229
00:11:02,360 --> 00:11:06,560
所以呢

230
00:11:06,560 --> 00:11:08,240
我们建议大家

231
00:11:08,240 --> 00:11:13,080
学习活动图

232
00:11:13,080 --> 00:11:14,640
背后道理都一样了

233
00:11:14,640 --> 00:11:16,040
但是活动图的话

234
00:11:16,040 --> 00:11:17,280
一个用途更广

235
00:11:17,280 --> 00:11:19,480
第二，背后的道理的话

236
00:11:19,480 --> 00:11:20,960
可以学的东西就更多

237
00:11:20,960 --> 00:11:23,440
因为背后道理会更加深刻一点

238
00:11:23,440 --> 00:11:24,880
因为有这个

239
00:11:24,880 --> 00:11:25,680
SysML

240
00:11:25,680 --> 00:11:27,280
这些东西的支持

241
00:11:27,280 --> 00:11:30,240
你学什么BPMN

242
00:11:30,240 --> 00:11:30,640
背后

243
00:11:30,640 --> 00:11:32,600
当然背后也有道理

244
00:11:32,600 --> 00:11:35,400
但是更多人看那个图很漂亮

245
00:11:35,400 --> 00:11:36,320
画个图

246
00:11:36,320 --> 00:11:36,800
这样的

247
00:11:36,800 --> 00:11:39,760
它不如活动图这样的

248
00:11:39,760 --> 00:11:41,200
背后道理这么深刻

249
00:11:41,200 --> 00:11:43,200
你要往下学的话
