The global market is characterized by unexpected and dynamic changes that can cause problems for manufacturers. The OASIS Production and Planning Scheduling (PPS) offers a way to standardize these bumps.
This open-source framework offers a standard for collaborative planning and scheduling between manufacturing industries. Manufacturers have used production-planning software, such as Enterprise Resource Planning (ERP) systems, to help them make decisions on long-term planning issues.
In the short term, though, situations evolve. When unexpected real market and shop floor demands change unexpectedly, the schedulers adjust their schedules. The PPS standard aims to bridge this gap between the planners and schedulers.
The PPS provides benefits across the supply chain. System integrators can use PPS to configure planning and scheduling software packages. Manufacturers can use PPS to better help them develop new planning and scheduling systems at less cost — particularly for applications that include multi-vendor products or legacy systems.
In particular, this standard focuses on collaborative information sharing in real-time between planners and schedulers on:
- Production planning orders
- Inventory levels
- Resource capacity
- Scheduled or in-progress operations
To simplify information sharing, the OASIS PPS Technical Committee focuses on developing a common XML schema on business process specification that planners and schedulers can use collaboratively when they need to respond to unexpected market changes (such as earthquakes, man-made disasters, and downward economic conditions). Without this capability, communication problems bare likely to plague planners and schedulers when trying to adjust production planning orders, inventory levels, and resource capacity.
When planners and schedulers share information, they can concurrently view on a screen, for example, discrepancies in inventory levels due to unstable market conditions in any country, any time. If the discrepancies are significantly large, they can collaborate to adjust inventory. For smaller blips, they can work together to smooth out inventory levels and avoid bigger adjustments later.
For example, if planners and schedulers discover a change in inventory status from “normal” to “surplus,” they can collaborate to create a method to dispose of surplus items. One method might be sending non-perishable surplus items to auctioneers to auction them off at lower prices. Another method might be reducing the inventory level until surplus items are sold. When there is an increase in the demand for the items later on, the inventory levels can be adjusted accordingly.
The PPS standard is one step forward in achieving collaboration in real time between planners and schedulers. What do you think about this standard? OASIS is inviting industry feedback, so let your ideas be heard. (You need to subscribe to the comment list to submit comments.)
