Optimizing Manufacturing Production Scheduling (MPS) using constraint programming

July 7, 2022

Optimizing manufacturing production whitepaper

Production scheduling primarily deals with arranging different jobs in various machines based on the timelines for each job. There can be numerous combinations of schedules possible. Production schedules can be designed to maximize the capacity utilization, minimize idle time of the machine, earliness, overall costs etc. Manual design of a schedule can be a tedious and time consuming task. There are a lot of dependencies which the scheduler needs to tweak based on a single change. Generating a production schedule targeting a specific objective function can be done using mathematical models. Mathematical models involve formulating the production scheduling problem as an optimization model wherein there is a certain objective function which needs to be optimized based on a set of constraints. Mathematical models generally outperform manually designed schedules which involve a lot of inter-dependencies among the jobs. Due to improvement in computational power, developing a production schedule using mathematical models is relatively quick and efficient.

State of the Market: The Critical Path to Digital Manufacturing

whitePaper | August 8, 2022

Similar to a perfect storm, manufacturers have been navigating a unique time of multiple challenges including supply-chain disruptions, economic uncertainties, and worker shortages. Digital transformation is supposed to ease these strains. Digitizing processes and adopting the right technologies can help achieve cost efficiencies, allow for scalability and growth, and overcome talent gaps

Data driven digital platforms for automotive transformation

whitePaper | June 20, 2022

It is almost cliché that the automotive industry is undergoing transformational change. Perhaps not since the Model T first revolutionized the industry has so much change come so quickly. Driving this evolution is the unstoppable momentum of a Connected, Automated, Shared, and Electrified (CASE) driven digital transformation, which is upending established norms and re-imagining the industry from the inside out. Linear, product-focused business models built on structured data are being replaced by collaborative, data-driven business ecosystems incorporating a broad group of traditional and non-traditional stakeholders and data types. The new value creation frontier is a differentiated, highly-curated, personalized customer experience.

2022 manufacturing industry outlook

whitePaper | March 14, 2022

It is unusual to see positive economic indicators paired with historic labor and supply chain challenges. But this is the trajectory for US manufacturing in 2022 emerging from the pandemic. The recovery gained momentum in 2021 on the heels of vaccine rollout and rising demand. As industrial production and capacity utilization surpassed pre-pandemic levels midyear, strong increases in new orders for all major subsectors signal growth continuing in 2022.

How to Get Started with Robotic Automation

whitePaper | May 11, 2022

Robotic automation is not a new concept, yet it can be difficult to fully grasp its complexity and overcome its barriers to entry. Which integrator is the best partner for this project? How do you approach your CFO with evidence that you should automate now? What tasks can you even automate? It can be difficult to make sense of all of the technical complexities and varying financial options, especially when you’re already managing other day-to-day responsibilities.

The New Face of Manufacturing

whitePaper | March 6, 2020

The manufacturing industry is undergoing tremendous change. The industrial revolution brought us assembly lines and mass production. The result was a dramatic increase in worker productivity. The digital revolution brings a host of new opportunities, enabled by data and the power and intelligence of cloud computing. However, it’s the talent, skill, and creativity of your people that determine success.

Accelerating value from data-driven manufacturing

whitePaper | November 4, 2022

For manufacturers, the challenge of ensuring that production efficiency is improved to the point that’s right first time, every time, is critical towards the ultimate goal of achieving zero defect manufacturing and all of the associated cost and sustainability benefits.
