Apparel manufacturers receive firm orders just a few months ahead but must plan capacity, materials, and production 6 to 24 months out. Short product lifecycles keep long-term forecasts at broad category levels, forcing decisions based on incomplete signals like brand partnerships and historical trends. This visibility gap risks over- or under-committing resources, leading to excess inventory or missed opportunities. 

Fashion demand shifts rapidly and unpredictably. Styles can be added, canceled, or scaled late in the cycle, while regional changes alter product mix. Manufacturers must forecast against brand decisions, seasonality, and promotions, with high penalties for misses: expedited production, rework, lost margins, or idle capacity.  

Manufacturers must maintain high asset utilization while flexibly scaling capacity up or down without eroding margins. This requires orchestrating demand across multi-site networks—balancing plant constraints, costs, capabilities, and service levels—to route each style through the most profitable production path. 

Strategic planning starts with rough Tech Packs that outline only the basic category, time estimates, and site requirements, rather than detailed BOMs, routings, or specifications. As production approaches, complete information arrives at different times depending on the customer and style. Managing this shift from high-level assumptions to finalized, line-level specifications adds significant complexity to the planning process. 

Allocations must balance hard constraints like capacity and accreditations with soft preferences such as plant priorities, costs, and minimum utilization. Multiple factors interact—duties, freight, efficiency, technical capabilities, category priorities, quality, and sustainability requirements. Manually optimizing service, profit, and asset utilization across sites is slow and error-prone. 

Sewing lines drive the production constraint. Efficiency varies by line, style, and production maturity, with costly changeovers and steep learning curves. Material availability further gates throughput. The challenge is balancing long runs for productivity against delivery deadlines while avoiding expensive overtime. 

RELEX combines ML forecasts with multi-version budgeting, scenario testing for cancellations and regional shifts, and variance analysis against actuals. Plans can be built in units, time estimates, or value across the full product hierarchy. Efficiency factors and learning curves translate production estimates into realistic capacity, costs, and timelines, linking sales signals directly to operational and financial outcomes. 

RELEX provides a unified, real-time view of the entire supply chain by continuously updating forecasts and plans with the latest data. This gives planners visibility into current performance, demand shifts, potential bottlenecks, and growth opportunities. Our platform aligns long-term strategic goals with operational execution, ensuring all planning horizons, from annual to daily, stay synchronized and responsive. 

Rough-cut capacity planning reveals line and site bottlenecks months in advance. RELEX identifies constraints across production, materials, transport, and storage while simulating labor ramps, overtime, and subcontracting options. This enables manufacturers to adjust product mix and replan early, avoiding costly last-minute overtime and expedites. 

RELEX uses mathematical optimization, a core AI technology, assigns volumes to accredited factories while respecting constraints and cost drivers like labor and freight, minimum utilization, and overtime rules. By embedding earnings per hour, the system steers work toward the highest-return sites, raising margins without sacrificing customer service. 

Executives see scenario-based profitability, capacity, and service trade-offs in one view. RELEX highlights overcommit risks, low-demand periods, and margin leakage by style and site. Decisions on slotting, pricing, and capacity are tied to financial metrics including earnings per hour, enabling flexible IBP cycles and collaborative decision-making when needed. 

RELEX applies AI-driven automation across planning functions, reducing manual effort, and eliminating errors. Yet it preserves full visibility and control for planners, who can focus on exception handling and strategic decisions. Intuitive workflows and tools like our Rebot assistant enhance productivity and enable smarter, faster planning.
