Leta 2007 se je tudi za gospodinjske odjemalce odprt trg z električno energijo. Posledica tega je svobodna izbira dobaviteljev električne energije za gospodinjstva, tržni pristop dobaviteljev, razvoj novih produktov električne energije in nanjo vezanih storitev. Stroški poslovanja dobaviteljev zaradi vseh naštetih posledic naraščajo, niža pa se ust...
Pig Latin is a popular language which is widely used for parallel processing of massive data sets. Currently, subexpressions occurring repeatedly in Pig Latin scripts are executed as many times as they appear, and the current Pig Latin optimizer does not identify reuse opportunities.We present a novel optimization approach aiming at identifying and...
In this thesis work we solve the problem of optimal placement and sizing of distributed generation by using an original Fuzzy Adaptive Particle Swarm Optimization algorithm and a Mixed Integer Linear Programming formulation of the problem. The goal of integrating Fuzzy Logic in Particle Swarm Optimization is to be able to overcome some of the class...
A multi-product multi-period aggregate remanufacturing planning problem involving uncertain input data is considered. A two-stage stochastic programming approach is investigated, resulting in the formulation of a large-size linear program. Preliminary computational results providing a first assessment of the value of stochastic programming for the ...
Collocation has been widely applied in geodesy for estimating the gravity field of the Earth both locally and globally. Particularly, this is the standard geodetic method used to combine all the available data to get an integrated estimate of any functional of the anomalous potential T. The key point of the method is the definition of proper covari...

One of the major challenges in measuring efficiency in terms of resources and outcomes is the assessment of the evolution of units over time. Although Data Envelopment Analysis (DEA) has been applied for time series datasets, DEA models, by construction, form the reference set for inefficient units (lambda values) based on their distance from the e...

In this paper, a new approach for solving transhipment model as a transportation model is developed and illustrated. The objective is to expose the transhipment problem to algorithms and methods that are transportation problem (TP) based. The principle of this method consists in merging source nodes with transhipment nodes, through utilization of a...
Schema matching is a key task in several applications such as data integration and ontology engineering. All application fields require the matching of several schemes also known as "holistic matching", but the difficulty of the problem spawned much more attention to pairwise schema matching rather than the latter. In this paper, we propose a new a...
It is proposed in this paper the automatic detection thresholds in the neutronic noise from a nuclear reactor chamber. The proposed method combines a pattern recognition algorithm, known as dynamic cluster and a linear programming algorithm. Euclidean distance, often adopted by default, in the dynamic cluster algorithm; is here replaced by the dist...
Customers’ individual preferences are calling for more variety of the firms offerings. Faced with this situation, firms endeavor to meet customer requirements while reducing their costs and impact on environment in order to remain competitive. Further on, achieving such a goal entails various issues that need to be tackled such as the multiple perf...
