DOT stands for Defect
Optimization Tool and as the name indicate the optimization also uses information
from the web inspection system. DOT is a real time system that performs a
powerful yet quick calculation (< 1 min) on every reel as they
materialize in the web inspection system. The result is a optimal cutting
pattern(s) for this reel.
produce a conventional production plan and therefore requires greater
dynamic capabilities for the mill in question (since the cutting pattern
are created on the fly). Nevertheless DOT follows a blue print of a
production plan that specifies the order stock, shipping dates, packing
information and more so at the end of the day DOT will decrease the orders stock
as planned. DOT also has the capability to follow/import a conventional
Trim plan. In this mode DOT is only invoked when necessary.
module is a power full optimization engine that for each reel (or set)
guarantees and optimal solution/pattern. This means that there doesnít
exist a single millimeter extra loss. The calculation also takes the
current order situation into account and selects patterns that matches the expected out come.
There is always a trade off between fulfilling the demand in a planned
manner and reducing losses. For example on massively defect reels DOT will
prefer narrow/cheap rolls. However DOTís functions for order control (the
blue print mentioned above) takes care of this for the user. In fact the
order control is so effective that it often mange to keep the whole
production from a full order stock down to zero completely optimal.
DOT has an
intuitive and rich operator interface that is ideal for decision support
Integration and Customization issues
We on Pepto
Systems are experienced in integration issues with a variety of production
systems and can integrate DOT transparently. In fact DOT can work
completely stand alone or just in read only mode consequently the impact
on your IT infrastructure is virtually none.
Since every mill
is unique and has itís own preferences and restrictions on how possible
cutting patterns may be constructed DOT is designed to be highly
customizable. The graphical interface is highly customizable or even
exchangeable. DOT is a module based application so virtually nothing is
impossible when it comes to rapid
