RSI helps enterprises assess their real supply chain challenges. We then enable improvement of the inventory, replenishment, network, and planning decisions that drive service, cost, and working capital.

The problem

Your Supply Chain Is Only as Strong as the Decisions It Makes Every Week

Most planning teams are not failing because they lack effort or knowledge. They are working with imperfect data, outdated formulas, and disconnected processes. They pay for it in inaccurate forecasts, costly expedites, overstock and understock in the same network, and working capital that stays tied up longer than it should.

RSI was built to address exactly this problem. Our founders spent their careers leading supply chain operations, managing planning organizations and optimizing inventory as the valuable asset it is. They built the system they wished they had access to: a simulation engine that excels at scenario analysis and optimization, paired with practitioners who work alongside teams to improve decisions and deliver results.

Our story
Why RSI is different

Supply Chain Expertise

Supply chain practitioners work side-by-side with your team, not behind a support ticket. The RSI team has led planning, inventory, distribution, and operations organizations at companies including Intel, IBM, Dell, and Raytheon.

Meet the RSI team

Better Science

Simulation-based inventory optimization is the core. RSI has expanded that engine into network balancing, prioritized planning, operating services, and AI automation, with deep analytics spanning all of them.

How the technology expanded

Continuous Decision Support

Monthly, weekly, and daily decision rhythms sustain improvement long after the initial assessment is executed. RSI experts deploy our technology to bring ongoing operational decision support to you on a cadence that works for your business.

Explore the services

We Amplify Planners. We Do Not Replace Them.

RSI gives planners better information, clearer priorities, and explainable recommendations while the client team retains ownership, control, and execution.

Our Operating Model

Every engagement follows the same path: assess where decisions are breaking down, then operationalize the improvements alongside your team and keep refining them over time.

Assessments and Services

Each one began as a problem a client asked RSI to solve.
A1–A5 Supply Chain Assessment Know what to fix before deciding what to implement. +

Five modular assessments. Your team scopes which modules to evaluate, and the findings drive which services we operationalize together.

  • A1 Inventory
  • A2 Network & Distribution
  • A3 Planning
  • A4 Strategy & Operating Model
  • A5 AI Adoption
Full service detail
O1 Inventory Optimization Simulation-based policies for every item, every location. +

Simulation-based, item × location inventory policies built for real-world variability rather than formula assumptions. The epicenter of RSI’s better science.

  • Best-fit statistical pattern for every item × location
  • Day-by-day simulation with random demand and random lead times
  • Monthly policies with a decision narrative for every item
Full service detail
O2 Network Balancing Move inventory where it creates the most service value. +

The network is rarely short on inventory. It is short on inventory in the right place. Every SKU × location is scored weekly against its own simulated policy.

  • Node-level Red / Yellow / Green / Blue health, refreshed weekly
  • Surplus nodes feed at-risk nodes before new POs are cut
  • Full-pallet, source-protected transfer recommendations by lane
Full service detail
O3 Priority Planning Services (PRIO) Prioritized, daily replenishment action for planners. +

Optimized policies turned into a prioritized, executable playbook: what to build, where, and when, at the SKU, cell, and location level.

  • Capacity-aware scheduling: Demand-Driven, Inventory-Target, Capacity-Fill
  • A ranked daily action list instead of a maze of exceptions
  • Proactive alerts on spikes, safety-stock gaps, and overstock
Full service detail
O4 Strategy & Operating Services Build the management system behind better decisions. +

The SIOP/S&OE management system that ties sales, planning, operations, and finance, wrapped in strategy, governance, change, and continuous improvement.

  • Strategy alignment and operating model design
  • Decision rights, governance, and escalation paths
  • Change management and a continuous improvement engine
Full service detail
O5 AI Automation We automated our own business. Then clients asked how. +

RSI built these capabilities inside its own business first, and clients asked for them next. Work starts with one well-defined piece and expands only where the result earns it.

  • Data preparation, validation, and exception handling automated end to end
  • Assistants over contracts, policies, specifications, and compliance material
  • Workflow and reporting automation across operations and customer support

Outcomes

Commonly observed across RSI client portfolios:
15–25%
Typical inventory reduction
Inventory Optimization
5–15%
Service uplift at receiving DCs
Network Balancing
30–50%
Planner time reclaimed from exceptions
PRIO
Pilot result
38%

Early PRIO pilot deployments have also delivered a 38% inventory reduction at one location within weeks of launch, freeing more than $88,000 in working capital, and RSI's simulation engine has been used to analyze tens of millions of SKUs across a range of industries.
