# **系统复杂设计实现** #

## 1 什么是系统和系统架构 ##

### 1.1 系统 ###

### 1.2 系统架构 ###

## 2 如何进行系统思维 ##

### 2.1 确定系统的形式和功能 ###

### 2.2 确定系统中各个实体以及他们的形式和功能 ###

2.2.1 初步分类：不同种类的系统确定实体难易度不同

2.2.2 整体论：从功能出发思考系统内外涉及的重要实体

2.2.3 聚焦：针对问题，状况，难题，系统利益相关者，涌现物分析重要实体

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hd21pbmc_size_16_color_FFFFFF_t_70 4][]

2.2.4 抽象实体本质，不关注细节

2.2.5 定义系统边界，与外围环境隔离。我们做的系统？外围环境？规章，契约？接口标准

### 2.3 确定系统中各个实体之间的关系 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hd21pbmc_size_16_color_FFFFFF_t_70 7][]

### 2.4 涌现与预测涌现 ###

## 3 分析复杂的系统 ##

### 3.1 分层 ###

### 3.2 分析实体之间的关系，实例，泛化，递归？ ###

### 3.3 有序思考：复杂系统不好确定底部和顶部，故建议由内而外分析 ###

## 4 形式分析和功能分析 ##

### 4.1 形式分析 ###

### 4.2 功能分析 ###

### 4.3 系统架构=形式架构+功能架构 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hd21pbmc_size_16_color_FFFFFF_t_70 13][]

## 5 与特定解决方案无关的概念 ##

### 5.1 特化和泛化 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hd21pbmc_size_16_color_FFFFFF_t_70 14][]

## 6 从概念到架构 ##

## 7 架构师角色 ##

## 8 将需求转换为目标 ##

## 9 管理系统复杂度 ##

### 9.1 复杂度认识 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hd21pbmc_size_16_color_FFFFFF_t_70 18][]

### 9.2 管理复杂度工具-分解 ###
