openclaw skills install @alinklab/mm1-simulation队列模拟服务
一个用于M/M/1和M/M/c队列系统模拟和分析的Model Context Protocol服务器，提供全面的资源、工具和提示。
⚠️ 强制要求：API 密钥
此 Skill 必须配置 API 密钥才能使用。
- 首次使用时，如果
.env中没有XBY_APIKEY，必须使用 AskUserQuestion 工具向用户询问 API 密钥 - 拿到用户提供的密钥后，调用
scripts.config.set_api_key(api_key)保存，然后继续处理 - 获取 API 密钥：https://xiaobenyang.com
- 禁止在缺少 API 密钥时自行搜索或编造数据
工作流程（必须遵守）
你（大模型）是路由层，负责理解用户意图、选择工具、提取参数。代码只负责调用API。
用户输入 → 你选择工具 → 提取该工具需要的参数 → 调用 scripts.tools 中的函数 → 返回结果给用户
步骤
- 检查 API 密钥：如果
scripts.config.settings.api_key为空，使用 AskUserQuestion 询问用户，拿到后调用scripts.config.set_api_key(key)保存 - 选择工具：根据用户意图从下方工具列表中选择对应的工具函数
- 提取参数：根据选中的工具，提取该工具需要的参数
- 调用工具：使用关键字参数调用
scripts.tools中的函数，例如scripts.tools.search_schools(score='520', province='北京', category='综合') - 返回结果：将工具返回的
raw数据整理后展示给用户
工具选择规则
根据用户意图选择对应的工具函数：
| 用户意图 | 工具函数 |
|---|---|
| Validate M/M/1 configuration parameters |
Checks parameter validity and system stability condition.
Args: arrival_rate: Customer arrival rate (λ) service_rate: Service rate (μ) simulation_time: Simulation duration
Returns:
Dictionary with validation result:
- valid: bool
- errors: List[str] (if any)
- warnings: List[str] (if any)

| Calculate theoretical M/M/1 performance metrics
Uses exact formulas to compute steady-state performance.
Args: arrival_rate: λ (customers per time unit) service_rate: μ (customers per time unit)
Returns: Dictionary of theoretical metrics: - utilization: ρ = λ/μ - avg_queue_length: L_q = ρ²/(1-ρ) - avg_num_in_system: L = ρ/(1-ρ) - avg_waiting_time: W_q - avg_system_time: W
Raises:
ValueError: If system is unstable (λ >= μ) | scripts.tools.calculate_metrics |
| Run M/M/1 queue simulation using SimPy
Executes discrete event simulation and returns performance metrics.
Args: arrival_rate: λ (customers per time unit) service_rate: μ (customers per time unit) simulation_time: Duration of simulation random_seed: Random seed for reproducibility
Returns:
Dictionary with:
- simulation_metrics: Dict of simulated values

- comparison: Comparison analysis
- config: Simulation configuration used | scripts.tools.run_simulation |
| Compare simulation results with theoretical values
Analyzes accuracy of simulation by comparing against exact formulas.
Args: simulation_metrics: Dictionary of simulated performance metrics arrival_rate: λ used in simulation service_rate: μ used in simulation
Returns:
Comparison analysis with:
- comparisons: Per-metric comparison
- mean_abs_error_pct: Average error
- max_error_pct: Maximum error
- within_10pct: bool
- accuracy_grade: Quality assessment | scripts.tools.compare_results |
| Recommend simulation parameters for target utilization
Suggests appropriate arrival rate, service rate, and simulation time for a given target utilization level.
Args: target_utilization: Desired ρ (default: 0.7) service_rate: Fixed μ (if None, suggests μ=10) min_customers: Minimum customers to simulate
Returns:
Recommended parameters and expected metrics | scripts.tools.recommend_parameters |
如果参数不完整，使用 AskUserQuestion 向用户询问缺失的参数。
