第四十六章
WSaiOS Cognitive Decision Engine认知决策引擎源码实现
46.2 Decision State Model状态管理系统源码实现
在46.1节中,我们完成:
- Decision Engine总体架构;
- Goal Analyzer;
- Decision Planner;
- Strategy Selector;
- Decision Object模型。
此时Decision Engine已经能够:
Goal
↓
Plan
↓
Action
但是,一个真正的认知决策系统不能只根据目标做决定。
因为:
同一个目标,在不同状态下,可能产生完全不同的行动。
例如:
目标:
提高系统运行效率
状态A:
CPU 90%
Memory 80%
可能:
减少后台任务
状态B:
CPU 30%
Memory 40%
可能:
优化缓存策略
因此WSaiOS设计:
Decision State Model
认知决策状态模型
46.2.1 Decision State Model定位
Decision State Model负责:
保存决策所需的全部上下文状态。
包括:
Goal State
+
Cognitive State
+
Environment State
+
Memory State
+
Execution State
形成:
Complete Decision Context

46.2.2 State Model设计原则
WSaiOS定义五个原则:
(1)Dynamic State
动态状态。
状态会随着运行不断变化。
例如:
CPU Usage
Memory
Task Queue
(2)Unified State
统一状态模型。
避免:
不同Engine:
使用不同格式。
(3)Observable State
可观察。
所有状态变化:
产生事件。
(4)Versioned State
状态版本化。
支持:
状态回溯。
(5)Serializable State
可序列化。
支持:
持久化存储。
46.2.3 Decision State目录结构
新增:
decision_engine/
├── state/
│
├── model.py
├── manager.py
├── updater.py
├── serializer.py
├── event.py
└── validator.py
46.2.4 Cognitive State认知状态模型
Cognitive State描述:
系统当前认知情况。
包括:
Current Goal
Current Knowledge
Current Reasoning
Current Confidence
文件:
state/model.py
源码:
from dataclasses import dataclass,field
@dataclass
class CognitiveState:
goal:str=""
knowledge:list=field(
default_factory=list
)
reasoning_result:str=""
confidence:float=0.0
示例:
{
"goal":
"Recommend Product",
"knowledge":
[
"Customer likes quiet motor"
],
"confidence":
0.88
}
46.2.5 Environment State环境状态
Environment State表示:
外部环境。
例如:
系统:
CPU
Memory
Network
Storage
Agent:
Location
Available Tool
Resource
源码:
@dataclass
class EnvironmentState:
cpu:float=0
memory:float=0
network:str=""
示例:
{
"cpu":
65,
"memory":
48,
"network":
"online"
}
46.2.6 Goal State目标状态
Goal State负责:
记录:
任务目标生命周期。
状态:
Created
↓
Analyzing
↓
Planning
↓
Executing
↓
Completed
源码:
@dataclass
class GoalState:
goal_id:str
description:str
status:str="created"
示例:
{
"goal_id":
"T001",
"description":
"Optimize System",
"status":
"planning"
}
46.2.7 Memory State记忆状态
连接:
Memory Engine。
保存:
历史决策。
例如:
Previous Decision
Previous Result
Success Rate
源码:
@dataclass
class MemoryState:
history:list=field(
default_factory=list
)
示例:
{
"history":
[
{
"action":
"Optimize Cache",
"result":
"success"
}
]
}
46.2.8 Decision State统一对象
文件:
state.py
源码:
class DecisionState:
def __init__(self):
self.cognitive=CognitiveState()
self.environment=EnvironmentState()
self.goal=None
self.memory=MemoryState()
def snapshot(self):
return {
"cognitive":
self.cognitive,
"environment":
self.environment,
"memory":
self.memory
}
46.2.9 State Manager状态管理器
负责:
- 创建状态;
- 更新状态;
- 查询状态;
- 保存状态。
文件:
manager.py
源码:
class StateManager:
def __init__(self):
self.state=DecisionState()
def update(
self,
module,
data
):
setattr(
self.state,
module,
data
)
def get(self):
return self.state
使用:
manager.update(
"environment",
{
"cpu":80
}
)
46.2.10 State Update状态更新机制
状态更新流程:
Engine Event
│
▼
State Updater
│
▼
Validate
│
▼
State Store
│
▼
Decision Engine
文件:
updater.py
源码:
class StateUpdater:
def update(
self,
state,
event
):
state[event.key]=event.value
return state
46.2.11 State Event事件模型
状态变化必须通知系统。
例如:
CPU变化:
产生:
StateChanged Event
源码:
class StateEvent:
def __init__(
self,
key,
value
):
self.key=key
self.value=value
发送:
EventBus.publish(
StateEvent
)
46.2.12 State Serialization状态序列化
用于:
- SQLite;
- 文件存储;
- Runtime恢复。
源码:
import json
class StateSerializer:
def serialize(
self,
state
):
return json.dumps(
state.__dict__
)
输出:
{
"environment":
{
"cpu":
70
}
}
46.2.13 Decision State运行示例
任务:
Reduce Energy Usage
当前状态:
{
"goal":
"Reduce Energy",
"cpu":
90,
"background_task":
20,
"history_success":
0.85
}
Decision Engine读取:
State
↓
Planner
↓
Strategy Selector
生成:
{
"action":
"Reduce Background Tasks",
"confidence":
0.87
}
46.2.14 与Runtime State Bus连接
