Does Darwin’s theory of evolution mean anything to you? Arima has drawn inspiration from it to design and develop a new way to optimize production scheduling … by simulating the process of natural selection.

From biology to artificial intelligence

A population of individuals will evolve from one generation to the next. When two individuals breed, their genes are intermixed and repackaged into new chromosomes, with some genes changing through mutation. If the offspring survive and reproduce, this will be because their genetic characteristics make them well adapted to their environment. The cycle is repeated, and their surviving offspring will be even better adapted.

So in biology a genetic algorithm is an iterative process that improves the quality of an initial range of solutions through recombination, mutation, and selection to form, with each new generation, a better range of solutions.

Syncrun applies this principle to its model of the production process. The “population” is all of the possible solutions for production optimization. The “gene” is the way a resource is assigned to an operation according to a specific production schedule.

This evolutionary artificial intelligence technique has an advantage over conventional optimization approaches: the solution comes with a comprehensive view of the relevant costs.

Components of the genetic model

An initial population of chromosomes/solutions is generated in line with basic scheduling rules. It then goes through a double process of selection: selection for reproduction and selection for survival—in other words, a chromosome/solution is selected if it survives into the next generation.

The algorithm breaks up the chromosomes and creates new ones by recombining the fragments. There are also mutations where two groups of genes swap their positions on the same chromosome. May the best team win!

Concrete applications

In practice, Syncrun’s genetic algorithm will aim for a production goal (produce on time, and at the lowest cost) by simulating hundreds of thousands of possible ways to reach that goal. Finally, it comes up with the most efficient solution.

With this pathbreaking approach, we can optimize a manufacturer’s complete planning horizon and cut all of the production costs for inventory maintenance, for setup time, for production time, and for use of available resources.

Advanced scheduling and planning systems have been central to the “Fourth Industrial Revolution” of the last few decades. Arima’s Syncrun solution has been a major ally for any company that wishes to join this revolution and boost its productivity.

A short history of Industry 4.0

For the Business Development Bank of Canada, Industry 4.0 is characterized by the growing use of digital technologies in businesses. It is the latest evolution of manufacturing, after mechanization (c. 1780), electrification (c. 1870), automation, and globalization (c. 1970-1980).

The goal is to create “smart” factories that will be “capable of greater adaptability […] and a more efficient allocation of resources, to respond more quickly to the market in a more customized way and at lower cost,” according to Quebec’s Minister of the Economy and Innovation (MEI).

Syncrun gets into the act

As a North American leader in advanced planning and scheduling (APS) for 25 years, Arima has closely followed this evolution of manufacturing. Syncrun’s smart algorithm meets several major needs of the digital revolution:

• advanced analysis of production scenarios;
• planning and optimization of processes in real time;
• resources allocation and optimization with the use of artificial intelligence;
• instant adjustment of the plan to conditions on the shop floor and unforeseen events.

Recent techological advances have led to a new licensing and delivery model called SaaS (Software as a Service), which makes it easier for businesses to access software products on demand. The Syncrun system is completely cloud-based. It’s managed by Arima to provide a simplified customer experience and greater value.
