Solutions - Trim Scheduling
Solutions®, the latest enhancement in computerized corrugator trimming, provides Plant Schedulers with the tools necessary to efficiently trim all paper grades. Using a newly developed alternative grade scheduling algorithm, Solutions produces the best, most cost efficient trimming solutions available.
Solutions simultaneously returns multiple trimming solutions based on a series of user defined cost parameters. By examining the results achieved in each solution, the Scheduler can evaluate alternative run patterns and select the specific schedule that best satisfies the Plants current needs - increased corrugator throughput, reduced side trim, reduced order splits, etc.
Solutions will develop better, more cost efficient runs that minimize wet end changes, dry end changes and help control the excess orders being scheduled that lead to material being inventoried, damage to sheets and congestion on the plant floor.
Key Benefits of Solutions - Trim Scheduling
- Produces the most efficient corrugator schedules possible fast and easily, allowing the Scheduler to concentrate on improving customer service and plant efficiency instead of number crunching.
- Considers all cost factors and provides decision makers with the best information needed to make the correct decision.
- Produces multiple solutions for each order pool allowing the scheduler to select the one that best fits the current business conditions.
- Solutions trims multiple grades in the same trimming session. Automatically considers upgrades for qualifying orders to create the most cost effective lineups.
- Provides special instructions which are visible through the entire scheduling and corrugating process. This reduces errors and improves communications.
- Provides a wide variety of useful reports aiding management, production and shipping in optimizing their processes.
- Automates communications of the corrugator schedule information to all equipment using Avista Setup Manager®.
Solutions automatically trims multiple grades in the same trimming session. Once qualifying orders are selected, lineups are generated using rollstock available at that time.
Alternate Trimming Grades
Solutions automatically considers upgrading orders with the goal of creating more cost effective lineups. The application weighs the decision to upgrade to a heavier board combination only when business rules permit and a cost savings exists. By configuring the board grades, we can specify the allowed upgrade path options for each grade that will be used in the Solutions scheduling strategy. For example, if you had 3 or 4 board grades that were within the same etc range, the scheduler may select all the grades at once. This will load all the orders in those grades into one screen. Upon selecting the required orders, Solutions will combine (keeping in mind the orders upgrade attribute) the orders in the most run/cost efficient manner.
If upgrading an order will improve the overall side trim loss, increase web utilization or reduce wet-end paper changes, Solutions will return that result set in the “Best Cost” solution displayed on the screen. If Solutions determines that the best cost efficient method is to schedule each in its own grade, it will do so. The approach helps improve corrugator through-put, thus providing cost savings.
Solutions includes a new method for calculating the cost of a schedule. Plants can use the original Opportunity Loss Cost calculation method, or a new Straight Cost Calculation method. This new method enables the plant to set costs for the following:
- Cost per Wet-end Paper Change Solutions® Trim System
- Cost per Slitter Change
- Cost per msf above the original msf for orders selected to schedule
- Cost per 100 feet for paper changes before a specified amount of lineal
- Cost per Percent Utilization below desired Target Utilization
- Cost of Upgrades
Solutions contains an Auto-Parameter switch which can automatically change the system parameters to allow Solutions to solve difficult scheduling problems. This will make the novice or even the more experienced scheduler’s task easier by allowing Solutions to calculate the minimum requirements for obtaining a successful schedule of selected orders.
Solutions offers an Auto-Scheduling feature which can run in Semi-Auto or Fully-Auto mode. The Semi-Auto mode allows the scheduler to identify required orders for trimming. Once these orders have been marked, one click of a button sets the Auto-Scheduling function into execution. Using plant specified auto-scheduling parameters, Solutions goes through each board grade or grades (if the “Upgrade Path” method is enabled) to create a schedule and a completed corrugator line-up with accompanying reports.
Fully-Auto mode works in conjunction with the Avista Converting Plant Scheduling engine. Solutions takes on more of a scheduling engineroll, scheduling orders that have been identified by the Converting engine to be scheduled. It will continuously loop, looking for orders that require scheduling.
Multi-plant & Multi-corrugator Scheduling
Solutions incorporates improved capability for Multi-Plant scheduling. This method allows for the scheduling of Multiple Corrugators per plant as well. With Solutions set to run in this mode, it can restrict scheduling views to display only orders for each specific plant and or corrugator. It can also be set to include in its display, orders generic to all plants. By assigning Plant Id and Alternate Plant Id to orders, Solutions is able to control scheduling by using the appropriate scheduling parameters for that plant’s corrugator and roll stock supply.
