Opcenter (Preactor) Advanced Planning & Scheduling
Siemens Opcenter Advanced Planning & Scheduling (formerly Preactor) has the largest installed base of any independent production planning and scheduling software in the world. With over 10,000 licenses shipped, more than 6,500 companies use Opcenter (Preactor) Advanced Planning & Scheduling worldwide.
Nearly 350 companies in North America, covering almost every manufacturing sector and ERP system, use Preactor. Lean Scheduling International has been implementing Siemens Opcenter (Preactor) Advanced Planning & Scheduling since 2001 and has the largest installed base of any Preactor partner in North America. Over 80% of all Preactor installs are within the LSI client base.
Although Siemens Opcenter (Preactor) Advanced Planning & Scheduling provides great functionality out of the box, its real power is that it is a complete tool set for building production scheduling solutions. Like a Lego set, it can be used to build your own unique manufacturing production scheduling solution which is what sets it apart from other APS solutions.
If you are satisfied with a mediocre manufacturing production scheduling solution, then there is no need to choose Opcenter (Preactor) APS, but if your intent is to create a scheduling solution that delivers immediate results while laying the groundwork for unlimited future improvements and innovation, then you need Siemens Opcenter (Preactor) Advanced Planning & Scheduling.
It is not always easy for others to understand what makes Siemens Opcenter (Preactor) Advanced Planning & Scheduling work when other systems don’t, but Preactor’s approach is fundamentally different. Most of the systems being offered today are based on algorithmic sequencing (optimization) techniques. Although Siemens Opcenter (Preactor) Advanced Planning & Scheduling can use algorithmic sequencing, it is primarily based on heuristics (rules) and it does not claim to “optimize” your master production schedule. Optimizing sounds wonderful, but in most cases, it is totally unrealistic and leads to disaster. The difference may sound insignificant, but having the ability to build your tribal knowledge into your manufacturing production scheduling solution is what allows you to take what has worked for you and just automate it. In a nutshell, this is what makes Preactor work in the real world.
Another dose of reality is that in our 20+ years of experience we have seen that it is almost impossible to identify all your scheduling requirements before you start your APS project. APS solutions built on algorithmic sequencing can be severely limiting and may not be able to replicate your needs. This means that even if your changes are possible (and they often aren’t), the developer is the only one who can make them. You are then at the mercy of the developer. Since Siemens Opcenter (Preactor) Advanced Planning & Scheduling is built with heuristics (rules), there is no need to involve the developer as you have complete control of the way the system behaves.
