The SIMATIC IT Preactor Advanced Scheduling range has been redesigned to introduce functionality that was previously only available at the highest level right the way through the range. All products in the Preactor AS range are interactive multi-constraint scheduling systems. This means that the availability of resources, additional constraints, such as tooling, and materials are all taken in to consideration during the scheduling process to ensure an accurate model of your environment. Orders can be scheduled quickly using intelligent built in rules and the planner also has the ability to manually interact with the schedule to make changes based on their experience or new information.
SIMATIC IT Preactor AS Standard
SIMATIC IT Preactor AS Standard has all of the features described above. It uses order based scheduling to which the user can apply a ranking or weighting in order to prioritise the orders. It schedules based on availability of resources, additional constraints and the materials required for the order.
SIMATIC IT Preactor AS Professional
SIMATIC IT Preactor AS Professional has a number of additional schedule optimization rules to deal with problems such as minimizing changeover times, preferred sequencing and campaigning. Composite rules can also be built with Preactor’s workflow tool.
SIMATIC IT Preactor AS Ultimate
SIMATIC IT Preactor AS Ultimate includes a developer licence (SIMATIC IT Preactor Ultimate Access) which gives access to the full flexibility that is possible with a Preactor system. The database schema can be altered as required, including adding tables and fields, and via the Preactor programming interfaces it is possible to create custom scheduling rules to solve specific scheduling problems and create custom data manipulation tools for use with the Preactor workflow engine.
SIMATIC IT Preactor AS Ultimate Viewers
The SIMATIC IT Preactor AS Ultimate Viewer is a system designed to be linked to a Preactor AS Ultimate schedule. A Preactor AS Viewer system allows interaction with the schedule but the changes cannot be saved. They can be used in the sales office to track the progress of orders and carry out order enquiries against a read only copy of the published schedule. Management can also use them to compare actual times with scheduled completion times to assess the performance of the production process. Viewers can also be used on a shop floor PC to provide the cell supervisor or machine operator with up to the minute work-to-lists generated by the Scheduling system.
SIMATIC IT Preactor AP imports current stock levels plus actual and forecast demand. It then considers rough cut capacity, pack forward figures, target days of stock cover, manufacturing preferences, minimum/maximum re-order quantities, re-order multiples, product shelf life, etc. to propose an accurate and achievable MPS.
Production capacity can be specified as a quantity, duration or weight. By using the Preactor calendar system capacity, production capacity can be varied over time. The capacity available then limits the production volume created in each period.
Once an initial Master Production Schedule (MPS) has been created, the data can be displayed as both stock profile graphs and capacity usage graphs. The MPS can be changed by simply clicking and dragging a point on the stock or capacity graphs, and the production of a particular item can be moved from one planning period to another. Any changes made will be reflected in all the linked plot and grid windows.
SIMATIC IT Unified Architecture Foundation (SIT UAF) offers several functional modules.
The project studio module, for application developers, is used to create functional blocks.
The Solution studio module, for system administrators and integrators, is used to set up and deploy solutions in execution environments. Other system modules provide additional functions. The event manager provides a function for advanced event and signal management.
SIT UAF includes predefined functional blocks to manage, track and trace all manufacturing activities with an advanced manufacturing task management system.
SIMATIC IT Unified Architecture Discrete Manufacturing (SIMATIC IT UADM) is a software product specifically designed and developed by Siemens by leveraging the SIMATIC IT Unified Architecture foundation. SIMATIC IT UADM is the specialized product addressing the needs of the discrete industry market. It is designed to satisfy the most common needs of industries in which specific macro areas are dedicated to executing sequential discrete manufacturing functions in order to produce the desired product.
