Production Planning

← Back to Expertise

Overview

Production planning bridges the gap between demand forecasts and manufacturing execution, translating business objectives into actionable plans that determine what to produce, when, where, and in what quantities. Effective production planning ensures that resources are utilized efficiently, customer commitments are met, and costs are controlled across the entire manufacturing network.

Our approach combines mathematical optimization, simulation, and industry best practices to create production plans that are not only optimal in theory but robust and executable in real-world manufacturing environments with inherent variability and disruptions.

Core Planning Processes

Aggregate Production Planning

Strategic capacity and output decisions over medium-term horizons:

• Demand-Capacity Balancing: Matching aggregate production rates to demand forecasts across planning periods
• Chase vs. Level Strategies: Evaluating trade-offs between workforce flexibility and inventory buffering
• Mixed Strategies: Combining overtime, subcontracting, inventory build, and demand shaping
• Seasonal Planning: Building anticipation stock for peak demand periods
• Budget Alignment: Ensuring production plans meet financial targets and cost constraints

Master Production Scheduling (MPS)

Translating aggregate plans into item-level commitments:

• Available-to-Promise (ATP): Calculating uncommitted inventory for customer order promising
• Rough-Cut Capacity Planning: Validating MPS feasibility against critical resource capacities
• Time Fence Management: Enforcing stability in frozen, slushy, and free planning zones
• Lot Sizing: Determining optimal production quantities balancing setup and holding costs
• Planning Bill of Materials: Managing product families and option percentages

Material Requirements Planning (MRP)

Calculating time-phased material needs:

• Bill of Materials Explosion: Cascading demand through multi-level product structures
• Net Requirements Calculation: Accounting for on-hand inventory and scheduled receipts
• Lead Time Offsetting: Timing order releases to meet parent-level need dates
• Lot-for-Lot and EOQ Policies: Applying appropriate order sizing rules by item class
• Pegging and Where-Used Analysis: Tracing demand sources for exception management

Capacity Requirements Planning (CRP)

Detailed capacity validation and load balancing:

• Work Center Loading: Projecting labor and machine hours from planned and released orders
• Finite vs. Infinite Loading: Choosing appropriate capacity models by resource type
• Capacity Leveling: Smoothing load profiles through order timing adjustments
• Bottleneck Identification: Detecting and managing capacity constraints proactively
• What-If Analysis: Evaluating capacity impact of demand changes and new products

Optimization Approaches

Linear and Mixed-Integer Programming

Mathematical models for optimal production plans:

• Multi-period production planning with inventory carryover
• Multi-product, multi-resource allocation with setup considerations
• Workforce planning with hiring, firing, and overtime decisions
• Transportation and distribution network integration
• Stochastic programming for demand uncertainty

Heuristic and Simulation Methods

Practical approaches for large-scale planning problems:

• Priority-Based Planning: Rule-driven allocation when resources are constrained
• Rolling Horizon Planning: Iterative replanning with updated information
• Discrete Event Simulation: Validating plan feasibility under variability
• Monte Carlo Analysis: Quantifying risk across demand and supply scenarios
• Decomposition Methods: Breaking large problems into tractable subproblems

Advanced Analytics Integration

Leveraging data for smarter planning decisions:

• Demand sensing and short-term forecast adjustment
• Yield prediction and quality-adjusted capacity planning
• Supplier lead time variability modeling
• Machine learning for planning parameter optimization
• Digital twin integration for scenario evaluation

Planning Horizons & Hierarchies

Strategic Planning (12-36 months)

Long-range capacity and network decisions:

• Facility expansion and technology investment planning

• Raw material shelf life and storage requirements
• Minimum order quantities and supply lot sizes
• Alternative materials and substitution rules
• Import/export regulations and customs lead times

Business Constraints

• Customer service level agreements and priorities
• Working capital and inventory investment limits
• Environmental and regulatory compliance requirements
• Quality standards and inspection capacity
• Contractual commitments and minimum/maximum volumes
