xby-mm1-simulation
DeepSeek Harness (DSH) 的插件：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。
功能
- set_xby_apikey — 在聊天中设置 API 密钥（自动持久化，重启有效）
- validate_config — 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)
- utilization: float (if valid)
- calculate_metrics — 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)
- run_simulation — 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
- theoretical_metrics: Dict of exact values
- comparison: Comparison analysis
- config: Simulation configuration used
- compare_results — 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
- recommend_parameters — 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
安装
方式一：从 GitHub 直接安装（推荐）
# 格式: dsh plugin --profile <profile> add github:<owner>/<repo>
dsh plugin --profile web add github:xby_skill/xby-mm1-simulation
方式二：从本地目录安装（开发模式）
# 仅用于本地开发调试
dsh plugin --profile web add /absolute/path/to/xby-mm1-simulation
方式三：通过 cordis.patch.yml 开发调试
dsh web --profile web --patch /absolute/path/to/dsh-ocr-plugin/cordis.patch.yml
