SkillChain-Gym: A Benchmark for Reskilling-Aware Production-Inventory Control under Disruptions

Summary

SkillChain-Gym is introduced as a new benchmark for reskilling-aware production-inventory control, addressing the critical need to treat workforce capability as a decision variable in planning. Unlike existing operations benchmarks that consider labor exogenous, SkillChain-Gym models a single-site environment with stylized worker skill-state dynamics, hard threshold certification, skill forgetting, and capacity-consuming training actions that compete with production for worker hours. The benchmark incorporates seed-controlled disruption scenarios, three feasibility modes, deterministic replay, and metrics covering operations, resilience, capability growth, and training-access distribution. Evaluations over 60-shift horizons using production-only, reactive adaptive, water-filling adaptive, and static-insurance policies reveal regime-dependent results. Training-capable policies consistently outperform production-only baselines, with maintenance training proving essential even without disruptions. Adaptive training is beneficial for visible bottlenecks, while static cross-training offers strong insurance against surprise shocks and absenteeism, with capacity slack and forgetting rates defining these operational regimes.

Key takeaway

For Operations Professionals managing production-inventory control, you must integrate workforce capability and reskilling directly into your planning models. Recognize that training competes for worker hours, and maintenance training is crucial to prevent skill decay. Your choice of training policy should be forecast-driven: adaptive training works best for visible bottlenecks, while a lean static cross-training plan provides robust insurance against unexpected disruptions and absenteeism. This approach enhances resilience and capability growth.

Key insights

Workforce capability is a dynamic decision variable in production planning, requiring integrated reskilling strategies for resilience.

Principles

• Workforce skills are dynamic and impact production.
• Training competes with production for worker time.
• Skill maintenance is vital, even without disruptions.

Method

SkillChain-Gym specifies a single-site environment with worker skill-state dynamics, certification, forgetting, and capacity-constrained training. It includes disruption scenarios, feasibility modes, and metrics.

In practice

• Integrate workforce reskilling into production planning.
• Implement maintenance training to counter skill forgetting.
• Use static cross-training for surprise shock insurance.
