AutoNester-T

Software package for automatic marker making on fabrics, sheet metal or wood

AutoNester-T optimizes the automatic placement of markers onto fabric panels, sheet metal, wood or other materials. By configuring the optimal nesting pattern, the software minimizes the amount of wasted fabric. Leading manufacturers in the garment and upholstery industries already implement this software to optimize their production.

Product Description

AutoNester-T is a software package for automatic marker making on fabrics, sheet metal, wood or other materials. It is widely used in the garment and upholstery manufacturing industry. It is able to nest any set of pieces within a very short time in an optimal way, minimizing wasted material, while taking into account various types of constraints. The efficiency of the markers achieved by AutoNester-T is competitive to experienced human nesters.

The AutoNester-T software is organized as a Dynamic Link Library (DLL) to be used as a developer's tool kit. Developers of CAD-systems can integrate AutoNester-T into their software.

We also offer the creation of custom-made standalone applications for the end user which can be used to create markers from special data formats.

AutoNester-T is constantly improved and more and more kinds of constraints are incorporated. Currently, the following constraints are supported:

  • stripe and plaid
  • pre-placed pieces
  • folded and mirrored pieces
  • folded markers
  • nap and flip restrictions
  • bundle support
  • rotation adjustable
  • tilt support
  • splitted pieces
  • dynamic halfpiece sharing
  • holes and defects in the fabric
  • splice marks
  • goal efficiency
  • time limits
  • unrestricted number of pieces

For a full description of the software's capabilities please have a look into the documentation.

AutoNester-T is coded in a platform-independent way and runs under Windows 95/98/ME/NT/2000/XP/Vista and Windows 7. Other platforms are supported on request.

Methods

AutoNester-T combines many of the latest optimization techniques in order to achieve the best results in a very short time. We use local search algorithms based on new variants of Simulated Annealing, multiply iterated greedy strategies, paired with efficient heuristics, pattern recognition techniques, and fast Minkowski sum calculators. In the local search algorithms, we use fully dynamic statistical cooling schedules and dynamic parameter choice.

For the calculation of optimality proofs and efficiency guarantees on markers we use a combination of branch-and-bound algorithms and linear programming.

Examples

The following markers have been calculated by the AutoNester-T software package. All runtimes refer to a standard PC with a 1.5 GHz processor. The colors of the pieces mark different bundles.

Skirts, 64 parts, efficiency 94.3%, 7 minutes.

Trousers, 64 parts, efficiency 89,1%, 5 minutes.

T-Shirts, 102 parts, efficiency 89.0%, 7 minutes.

Commercial Software

The AutoNester-T software package for automatic placing of patterns on fabric can be used via an application programming interface (API). The software package addresses developers of CAD-systems for the textile manufacturing industry and industries with compatible packing problems. CAD-system developers can easily integrate AutoNester-T into their own CAD-software. On request, we also build tailormade standalone applications for our customers which are based on the AutoNester-T kernel.

AutoNester-T is available for all Microsoft-Windows-PC-Operation systems.
