Preactor Plugin

With over 20 years experience in scheduling systems for the manufacturing industry, The Scheduling Business would like to present:

In a world where small improvements lead to big returns, AI Wallace provides a huge step forward in scheduling technology.

Producing optimised schedules for complex data sets and manufacturing problems has never been easier. Using evolutionary AI, Wallace will produce measurable improvements in revenue, downtime and turnaround. Solving problems out of the reach of classic scheduling approaches, while being more reactive and adaptable.

What is AI Wallace?

Wallace is a Smart AI Scheduling Engine which works on top of Preactor to provide a powerful flexible solution to complex scheduling problems, adapting to changing requirements.

Traditional Approach

Until now, when the standard Preactor sequencing rules were not sufficient to handle your scheduling capabilities the only option has involved hiring a Preactor developer to build a custom scheduling rule. This process is slow, expensive and requires the developer to have a good understanding of how to convert knowledge often held by a select few employees into scheduling rules.

Your goals and requirements may change as time goes on. Once these hard coded rules have been created any updates require more custom code development and cost.

The Wallace Approach

AI Wallace works on a plug and play approach. It works from a simple installation process and uses data from within your current Preactor system. Installation can be done within hours, compared to the time it takes on a standard Preactor system.

Requirements on what makes a good schedule are split up into human language rules.

“For our business, reducing setup time is twice as important as reducing schedule length”.

AI Wallace understands these requirements and will create continuously improving schedules based on your criteria.

Powerful AI Scheduling


AI Wallace is built with modern frameworks and cutting edge techniques. We’re passionate about optimising every aspect of our code to bring you lightning fast scheduling, without the baggage of legacy systems.


Preactor must rely on a significant amount of human input to produce a reasonable schedule. AI Wallace’s Smart Evolutionary Algorithms produce complex optimised schedules with no human input.


Unlike traditional “hard coded” scheduling rules, AI Wallace is fully flexible. If you decide what makes a “good” schedule for you has changed, Wallace can be notified about these changes and will adapt accordingly.


AI Wallace builds an initial schedule then looks at the schedule as a whole before making 1000s of changes, continuously improving and optimising as it goes. This allows Wallace to tackle questions which require a finished schedule to answer such as “Can we reduce the time it takes from when an order starts until it ends?”.


Without the need for human input, AI Wallace can react to machine breakages and other unplanned alterations within minutes.

As AI Wallace produces complete optimised schedules without human impact, once machine exceptions have been logged in Preactor AI Wallace can produce an adapted schedule in minutes. As AI Wallace rarely takes holidays and works 24/7 it is always available.


Success in industry relies on advancements in techniques and technology. These improvements are made by understanding the data we have, the data we need and the goal we want to reach. Manufacturing Scheduling is no different. AI Wallace quantifies each schedule it produces using its knowledge from past schedules, current data and your business goals to produce increasingly optimal schedules.

Easy Integration With Preactor

At The Scheduling Business we have worked hard to provide AI Wallace as a plug and play solution. It can be installed within minutes using a one click install process. Once installed, AI Wallace will pull all the data it requires from your Preactor system. Once AI Wallace has generated a schedule this is passed back into Preactor. This means there is no change in how you pull data into Preactor, or how you view/report on schedules.

Able to setup without industry knowledge?

Writing advanced rules requires the developer to understand requirements.
Business requirements described in simple english, AI Wallace creates rules.

Continuous Schedule Improvement?

Produces an ordered list and puts these on the schedule one at a time in a single pass.
1000s of iterations as AI Wallace continuously improves on its previous schedule.

Optimise by overall time?

The scheduling engine works forward in time one operation at a time, it can’t know how long the schedule might be.
AI Wallace builds an initial schedule and uses this as a base for continuous improvement.

Smart materials management?

Materials linked in due date order prior to scheduling.
Materials add to a "pool" of materials and are used when required.

Ask A Question
Complexity, Without the Complications

As Wallace uses AI Evolutionary Algorithms to work out how to produce the best schedule for you, there are no hard coded schedule rules. No requirement for a developer to understand your complex requirements and no costly development time. If your business needs change, rules can be updated to change the importance of different factors or add new ones.

Wallace makes this easy.
