Preactor GMPS

Graphical Master Production Scheduling by Preactor.

The Preactor “P400 GMPS” module is a planning system that is ideal for FMCG companies or other manufacturers who make to stock or are driven by customer forecasts and next day delivery requests.

Database scalability, Excel friendliness

Many companies use spreadsheets to generate their MPS. It’s a very user friendly experience.

But is it scalable and does it depend too much on the person who created the formulae?

Preactor GMPS utilises a SQL database and the well known capabilities of Preactor’s scheduling tools.

And you can quickly change the suggested production, by typing in the grid area OR by drag and drop on the graph elements!

Master Production Scheduling

At the top of the Demand Management tree sits MPS. It’s purpose is to propose, for finished goods items, a production plan that keeps the days cover of stock within satisfactory upper and lower limits.


Preactor GMPS calculates the required production for each period and charts the financial impact of holding finished stock.

Preactor’s long history of producing software for manufacturing underpins GMPS, providing rough cut capacity management and (optionally) a firm plan period based on an underlying Preactor FCS or APS scheduling system.
