Running optimization

When all the information needed for the plan is defined (stocks, parts, settings), you can start to perform the optimization of cutting layouts.

To start calculation of cutting layouts for the current plan, click the button play_24 in main toolbar. You can also run optimization directly by pressing F3 or by selecting "File > Start optimization" from the menu. You don't have to switch to Results form, the program does it automatically. During the optimization, you can watch its progress and the best results which are achieved.

2D_Optimization

You can stop optimization process at any time by clicking the button stop_media_24 in the main toolbar or by pressing Esc. In such case following confirmation dialog appears.

2D_OptimizationConfirm

If you click the button [Yes], program will stop the optimization and the values will be saved to the plan. Previous results will be overwritten by values which were found in the moment the optimization process was interrupted. If you click the button [No], the optimization will continue.

When optimization is finished, the best cutting layouts will be automatically entered to the plan. The cutting layouts which were saved the last are always stored for next potential use (additional printing of reports, statistics, etc.).

2D_OptimResults

XD_MsgTip

Tip: When you choose particular plan in Plans form and you click the Results tab, you can immediately go over cutting layouts and summary of data which were saved the last.

Layouts

Following data grid shows the cutting layouts which were calculated by the program and user is immediately able to see their overview.

Cost

-

Overall cost of the plan.

Yield

Achieved utilization in percentage taking into account produced remnants.

[(Sum area of used parts / (Sum area of used stocks - Sum area of produced remnants)]

Absolute value of achieved utilization taking into account produced remnants.

[Sum area of used stocks - Sum area of produced remnants]

Gross yield

Achieved utilization in percentage not taking into account produced remnants.

[Sum area of used parts / Sum area of used stocks]

Absolute value of achieved utilization not taking into account produced remnants.

[Sum area of used stocks]

Stocks

Number of stocks used in calculated cutting plan.

[Sum area of used stocks]

Parts

Number of parts used in calculated cutting plan.

[Sum area of used parts]

Remnants

Number of reusable remnants produced in calculated cutting plan without newly created remnant rolls.

[Sum area of remnants]

Layouts

Number of layouts of calculated cutting plan.

-

Uncut parts

Number of uncut parts (not used parts) in calculated cutting plan.

[Sum area of uncut parts]

Layout

Graphical representation of the layout which is currently selected.

2D_OptimLay

XD_MsgTip

Tip: When clicking on individual part of a layout, basic information about it is showed (part number, position in layout, size, edge bandings).

XD_MsgTip

Tip: After double click on part or remnant, associated report is printed (e.g. label report). See more in Reports.

It is also possible to browse between cuts. Red line in the layout image demonstrates currently selected cut. You can immediately know position (vertical/horizontal) of selected cut.
