Product Overview
Preactor is a family of products. Although all Preactor systems are based on exactly the same core code, they have different levels of functionality and price points so that the user can select the version that meets their specific needs and the budget available.  Because all versions share common code, upgrading from one version to another is easy and straight forward.

Preactor 100 FCS
Preactor 100 FCS is a fixed configuration version of Preactor with the goal to be deployed quickly.  Its scheduling algorithm uses priority or due date to decide the order sequence, and generates a good, achievable schedule, days, weeks, even months ahead.

All product information such as routing (operational steps, setup and run rates) resources, workcenters and shift patterns are held in SQL.  Microsoft Reporting Services is used to provide the schedule reports, and additional reports can be created with tools such as Visual Studio.

Preactor 100 FCS also has features such an import/export wizard, schedule web publisher, capable to promise enquiry tool, and user definable operation and product attributes but cannot be customized to the same degree as higher versions of Preactor.

Preactor 200 FCS

The Preactor 200 FCS is the starting point for users wishing to integrate their solution with other packages such as ERP, MES and data collection tools.  The SQL database is fully customizable allowing its structure to be altered to fit the needs of the user.

When generating a plan or schedule Preactor 200 FCS allows more than one type of resource to be occupied, for example a machine, operator and tool, at the same time.  The primary resource is treated as finite (only one batch can use it at one time) while the usages of other resources are displayed as plots.   These plots can display the number of each resource required over the period of the schedule and the user can interact with them to overcome violated constraints.

Additional scheduling features available in Preactor 200 FCS include the ability to define different run speeds for an operation from one resource to another, have sequence dependent changeover times based on product or operation attributes, allow overlapping (transfer batching) and splitting of operations, automatic schedule repair, and has an additional schedule analysis tool to compare one or more saved schedules with each other.

The Preactor ActiveX interface (API) is available in Preactor 200 FCS. This interface allows macros, typically written in Visual Basic, to be added to Preactor for data validation, integration, reporting, etc.

Preactor 300 FCS
Preactor 300 FCS has a number of extra features.  Firstly, at a detailed scheduling level P300 FCS has additional features including multiple finite resource constraints for each operation, routing control depending on resources selected, modeling of multiple batches on the same resource such as ovens and tanks, and mid batch updates on completed quantities.  It can also be used with the Graphical Master Production Schedule configuration for medium and long capacity planning. This allows the user to generate a finite plan months even years ahead using Preactor’s planning engine to model the interaction between demand (orders and forecast), current stocks and production capacity on the predicted inventory levels for each product.

Preactor 400 APS
Preactor 400 APS has a number of schedule optimization rules built-in to deal with such problems as minimizing changeover times, preferred sequencing, bottleneck scheduling and campaigning. Composite rules can be built using Preactor’s Event Script Processor to selectively apply a sequence of the standard rules. However, if these rules do not meet the exact requirements, then unique rules can be added as Visual Basic macros.

Material control via the concept of order pegging is also a feature of Preactor 400 APS. Typically the MRP process will create separate manufacturing orders for each component at each level of the BoM and may also consolidate parts for many different sales orders.  Preactor 400 APS can use the BoM structure together with user definable pegging rules to link or peg orders together.

These links are used during schedule generation so that if, for example, the material produced by an order is delayed then the impact on the order(s) it supplies can be established.  This can be extended to purchase orders for bought-in items and to sales orders so full material traceability is available.

Preactor 500 APS
Preactor 500 APS adds the Preactor BoM eXploder (PBX) to the features of Preactor 400. Although other Preactor systems have a Capable To Promise (CTP) function, when a BoM explosion and/or netting off of current stocks and work in process is required to produce the order promise response, then the Preactor 500 APS is required.  As an enquiry is entered into Preactor 500 APS, orders for each component at each level of the BoM are created, including routing.  It then links or pegs the orders together and overlays them on the current schedule taking into account all resource and material constraints, to give a realistic promise date.

Preactor 600 APS
Preactor 600 APS provides a 24x7 system that deals with order promise responses from multiple sources without the planner being present.  P600 APS has two licenses for two scheduling systems that run in parallel.  One holds the current up to date schedule and is always on-line.  The other can be used by the planner to view and carry out ‘what if’ manipulation of the schedule off-line.

Preactor Viewers
The Preactor Viewer is a view only system designed to be linked to one or more Master Schedulers (MS) over a PC network.  Data is passed between the MS (P200FCS and up) and the Viewer using a store and forward communication system, PCO.  Viewers can be located in different departments around the facility. They can 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 MS, and to log updates for the MS.  Viewers can be linked to bar-code readers to take progress information automatically. They can also be used in the sales office to track the progress of orders and by management to compare actual times with scheduled completion times.
