I am currently an Associate Professor and the Head of the Christian Doppler Laboratory for Artificial Intelligence and Optimization for Planning and Scheduling at TU Wien (Vienna University of Technology). I obtained in 1996 the degree 'inxhinier i diplomuar' (equivalent with Dipl.-Ing, master's degree) in the Faculty of Electrical Engineering (field of computer sciences and telecommunications), University of Prishtina, Kosova. I received my Ph.D. in Computer Science from Vienna University of Technology in October 2001 (download thesis ).  In October 2007 I finished my Habilitation (professorial qualification) in area of Applied Computer Sciences at the Vienna University of Technology.

Software

Contribution to Commercial Scheduling Software Packages

  • I have been one of main developers of algorithms in software packages:
    • First Class Scheduler – FCS (part of Shift Plan Assistant (SPA) of Ximes Corp.): This package is internationally recognised software for rotating workforce scheduling, and is licensed and used since 1999 in many companies in Europe.
    • Operating Hours Assistant (OPA 1.0) of Ximes Corp.: This package is used successfully and licensed since year 2000 in different companies in Europe like airports, call centres, hospitals, etc. 
    • For generation of shifts with breaks: This software was included in OPA 2.0, and was used from different companies in airports, call centres etc.   
  • I have been working on developing of algorithms and object oriented design for RAS (The Representation and Analysis Software): Software of Ximes Corp. for the US Department of Transportation.

 

 

Hypertree Library

Includes several algorithms for generation of hypertree decompositions. I have been working on developing of some algorithms in this library. The algorithms have been evaluated for benchmark examples from the literature and the industry

 

 

Benchmark Problems

Shift Design Problem

Includes three different sets of randomly generated examples for the shift design problem

 

Shift Design and Break Scheduling

Includes real life and random instances for the shift design and break scheduling problem

 

Rotating Workforce Scheduling

Includes 20 benchmark problems for rotating workforce scheduling problem. Example 1-3 appeared earlier in the literature, and other 17 examples are real life problems

 

Hypertree decomposition - CSP Hypergraph Library

This collection of problems contains hypergraph representation of several classes of CSP instances. These instances include industrial examples and randomly generated examples. These problems are used for evaluation of hypertree decompositions algorithms
