Abstract

The method involves treating time as a relative parameter instead of an absolute parameter in accordance with Einstein's Theory of Relativity. A time dilation takes place and the variation of the time parameter is coupled to that of the control parameter for the optimization method.

Description

Aus der Physik stammende bzw. in der Physik angewandte Optimierungsver­ fahren, wie z. B. das "Simulated Annealing" (Simuliertes Ausglühen) Verfahren haben sich in den vergangenen Jahren in der Praxis sehr gut bewährt. Hierzu sind als Beispiele Tourenplanungsprobleme und Reihenfolgeprobleme für Produk­ tionslinien zu erwähnen. Diese Anwendungen gehen im wesentlichen auf nume­ rische Simulationen für die physikalische Problemstellung der Spingläser zurück /1/. Das Auffinden des Grundzustandes eines Spinglases ist ein Np- vollständiges Problem.Optimization ver. Originating from physics or applied in physics drive such. B. The "Simulated Annealing" process have proven themselves very well in practice in recent years. For this are examples of route planning problems and sequence problems for products mention lines. These applications are mainly based on nume simulations for the physical problem of the spin glasses /1/. Finding the ground state of a spin glass is a complete Np Problem.

In der Praxis enthalten Optimierungsprobleme aber noch zeitabhängige Kom­ ponenten. Als Beispiele seien hier in der Tourenplanung Zeitfenster und zeitabhängi­ ge Abstandsmatritzen zu nennen. Ihre Behandlung in statistischen Optimierungs­ verfahren stößt in komplexeren Fällen auf Probleme. Dies trifft insbesondere auf zeitabhängige Abstandsmatritzen zu. Eine Lösung dieses Problems wird in diesem Patent angegeben.In practice, optimization problems still contain time-dependent com components. Examples of this are time slots and time-dependent in tour planning to name ge spacing matrices. Your treatment in statistical optimization procedure encounters problems in more complex cases. This is particularly true time-dependent spacing matrices too. A solution to this problem is in this Patent specified.

Die Zeit wird nicht mehr absolut, sondern analog zur Einsteinschen Relati­ vitätstheorie als relativ angesehen.Time is no longer absolute, but analogous to Einstein's Relati vity theory viewed as relative.

In der Praxis heißt dies, daß der Zeitrahmen für eine Tourenplanung, der etwa zwölf Stunden beträgt, auf einen höheren Wert gesetzt wird. D. h. es findet eine Zeitdilation statt. Der entstandene Zeitfaktor wird mit dem Kontrollparameter etwa der Temperatur im Simulated Annealing verändert. Bei tiefer Temperatur, bzw. gegen Ende des Optimierungslaufs: soll der Zeitfaktor wieder auf eins gesetzt werden, also keine Zeitdilatation mehr vorhanden sein. Es findet also im Falle des Simulated Annealing neben dem "Annealing" der Temperatur ein analoges "Annealing" des Zeitfaktors statt.In practice, this means that the time frame for tour planning, the approximately is twelve hours, is set to a higher value. That is, it finds one Time dilation instead. The resulting time factor is used with the control parameter the temperature in the simulated annealing changed. At low temperature,  or towards the end of the optimization run: the time factor should be set to one again there will be no time dilation. So it takes place in the case of the simulated annealing in addition to the "annealing" of the temperature an analog "Annealing" of the time factor takes place.
