Reactive scheduling is often been criticized for its inability to provide timely optimized and stable schedules. So far, the extant literature has focused on generating schedules that optimize shop floor efficiency. Only a few have considered optimizing both shop floor efficiency and schedule stability. This paper applies a unique selfadaptation mechanism of the ant colony optimization (ACO) al...

We study an optimization aspect of Internet shopping with price sensitive discounts from customer perspective (which is a specific case of the Internet Shopping Optimization Problem [1, 5]). Specifically, we consider a problem in which a customer would like to buy products of a given set N = {1, . . . ,n} in a given set of Internet shops M = {1, . . . ,m} at the minimum total final price. There...

In response to Dr. Homasson, my comments are as follows: 1) Mv paper is about a personal experience with laser bronchoscopy Ofll\ 2) In the introductii)n, I mentioned a statenient by Dr. Shapshav drawn from reference 1 of my paper. 3) I have flO personal experience with that technique and therefore I am unable to judge Dr. Honiasson’s letter. I think Dr. Shapshay or Dr. Sanderson, who initiated...

In this article we present an Ant Colony Optimization approach to the Flow Shop Problem. ACO is a new algorithmic approach, inspired by the foraging behavior of real ants, that can be applied to the solution of combinatorial optimization problems. Artificial ants are used to construct solutions for Flow Shop Problems that subsequently are improved by a local search procedure. Comparisons with o...

In this paper we study specially structured two stage flow shop scheduling problem with jobs in a string of disjoint job blocks having sequence independent setup times separated from processing times each associated with their respective probabilities including job weightage. In flow shop scheduling optimization of elapsed time may not always result in optimization of utilization time. Here, th...

This research introduces three heuristic algorithms for solving job-shop scheduling problems, job-shop scheduling problems with multi-purpose machines, and open-shop scheduling problems. All these algorithms are based on the particle swarm optimization algorithm, and generate solutions that belong to the class of parameterized active schedules via their specific decoding procedures. Comparison ...

In the last years, study of debris flow has become very important in research activity and engineering practice. The use numerical models is able for flow’s propagation. area located north-east Sicilian coast particular municipality Gioiosa Marea, severely affected by landslides occurred from 2000 to 2013. this case study, FLO-2D code been used. soil parameters determined means situ investigati...

Recently we found that (pentafluorophenyl)xenon(II) hexafluoroarsenate [CöF5Xe]+ [AsFö]reacted easily with xenon difluoride and FLO in HF to yield (pentafluoro-l,4-cyclohexadien-3-onl-yl)xenon(II) hexafluoroarsenate [1], In order to prove the scope of the synthetic use of this new powerful oxygenating reagent, the interaction with pentafluorobenzene derivatives C6F5X containing electron-donor a...
