From Constraint to Control: How Chartwell Digital Transformed Scheduling at a Chemical Manufacturing Site

Digital Insights

A chemical manufacturer was operating below potential, with an already-bottlenecked asset losing an additional 5–10% time from waiting on upstream and downstream material— a challenge previously uncovered during an initial Chartwell site visit. While the client wasn’t ready for a full-scale Chartwell improvement project, they hoped to generate some initial results through a digital approach.
Enter Chartwell Digital.
By collaborating closely with the site’s production manager and process engineer, our team developed a bespoke, rules-based scheduling tool. Built directly into their existing technology stack, the solution required no new software and delivered dynamic, real-time scheduling with embedded operational logic. Unlike generic off-the-shelf tools, this custom-built solution combined deep manufacturing expertise with tailored algorithms to unlock capacity, increase visibility, and enable smarter, faster decisions.
The Challenge: Bottlenecked capacity and fragmented planning
A high-volume chemical manufacturer was capacity constrained at a critical point in the production process. An initial Chartwell site visit had revealed a significant opportunity: a key asset was losing between 5% and 10% of its potential time each month.
While the operations team was keen to act, they didn’t want to commit to a full end-to-end improvement project. What they did want was a tool that could help them schedule more effectively — something to give them clarity and control over how work moved through the site.
Until this point, monthly production campaigns were built manually in Microsoft Excel. The approach was cumbersome, complex, and time-consuming to update as conditions changed. There was little visibility into the impact of different scheduling decisions on profitability, utilization, or output. The team needed something better — but not something bloated or expensive to integrate.
Off-the-shelf solutions didn’t cut it
Several software vendors offered generic scheduling platforms, but none fit the bill. These tools didn’t account for the nuances of the client’s process: unique asset quirks, product routings, or shift-specific constraints. Most would also require a new layer in the tech stack, creating cost and friction the client wanted to avoid.
What the client really needed was a scheduling solution built around their operations, not the other way around.
Chartwell Digital’s approach: A purpose-built scheduling tool
Chartwell Digital stepped in with a different approach. One that combined advanced digital capability with the firm’s trademark operational insight. The Chartwell Digital team partnered closely with the production manager and a site process engineer to design a bespoke scheduling tool, developed in two phases.
The foundation:
- Built directly into the client’s existing technology stack — no new software required.
- Integrated with real-time asset data and sensor feedback.
- Including interactive visual components and dashboards.
- Structured around real-world constraints, labor patterns, and operational logic.
Phase 1: Upstream optimization – unlocking latent capacity
The first phase focused on the upstream portion of the manufacturing process where many assets fed into a smaller set of downstream equipment.
This part of the site included over 15 assets and a limited number of products. The key issue was that the upstream flow couldn’t reliably keep up with improved downstream performance. Downtime, misalignment, and congestion through shared assets were common.
Chartwell Digital’s team:
- Designed an algorithm to ensure upstream scheduling would support maximum-speed performance downstream.
- Created a rule-based logic structure that included process settings, shift patterns, and asset-specific constraints.
- Automated the creation of a monthly campaign schedule, replacing the manual Excel-based approach.
The result: upstream operations could now be planned around optimal performance targets rather than historical averages, reducing delays and setting the stage for downstream improvements.
Phase 2: Downstream optimization – boosting the bottom line
The second phase addressed the downstream part of the site. While there were fewer assets, it was significantly more complex, with over 70 SKUs to manage.
The team designed a smarter scheduling engine that could:
- Match products to the best-performing or most cost-effective assets.
- Order and group products to minimize losses from changeovers and cleaning time.
- Automatically generate schedules that balance profitability, utilization, and throughput.
- Update in real-time based on what machines were actually doing — no manual adjustments required.
- Adapt for workforce changes, such as planning around reduced staffing levels.
Operators were given a clean dashboard to guide them through execution, while production leaders could compare alternate plans based on output and profitability.
Intelligent scheduling for real-world complexity
Unlike off-the-shelf systems, the Chartwell Digital scheduler embedded operational expertise directly into the logic. Now, the planning is based on the actual step times and flow rates by product by asset, which can be individually updated as improvement happens. Embedded logic included:
- Product routings
- Labor rules
- Process-specific run settings
- Line-by-line constraints
- Historical knowledge from experienced operators
As a result, the tool wasn’t just accurate, it was intelligent. It could account for variations and real-time conditions that static plans or generic software could never manage.
The scheduling engine also provided:
- A shared view across teams, eliminating fragmented data sources.
- A drag-and-drop interface for easy adjustments.
- Commenting and notes for better team communication.
- Built-in profitability and performance metrics to guide smarter decisions.
Why Chartwell Digital was the right choice
What set Chartwell Digital apart wasn’t just the technology — it was the approach:
- Deep operational insight: The solution was designed by people who understand manufacturing.
- Rapid prototyping: A design and proof of concept that was ready in 3 weeks for each phase.
- Integration-first mindset: The scheduler was built inside the tools the client already used.
- Practical focus: Every feature was aimed at improving output, cost, and clarity.
This wasn’t a digital overlay — it was a purpose-built tool designed to deliver measurable operational improvement.
Results delivered
- Capacity unlocked: The scheduling tool maximizes the profitability of the initial plan while dynamically minimizing losses in plan execution.
- Time saved: The production manager no longer had to maintain complex Excel sheets. Time previously spent on manual planning is now focused on leading operations.
- Real-time execution: The tool updates based on live asset data. If an asset goes down, the system can reassign work dynamically.
- Increased visibility: Everyone, from operators to leadership, works from the same data and schedule.
Looking ahead
The success of this pilot has opened the door for further deployments. The client is now exploring how the same approach could be scaled to other sites and to improve performance across the network and expand the impact of their digital investments.
