The university course timetabling problem involves assigning a given number of events (including lectures, seminars, labs, tutorials, etc) into a limited number of timeslots and rooms subject to given set of constraints. Two primary hard constraints are that no student should be assigned two events in one timeslot and that capacity and features of rooms should satisfy the requirement of the eve...

Abstract This article presents a mixed-integer programming model for solving the university timetabling problem which considers allocation of students to classes and assignment rooms time periods each class. The was developed as part our participation in International Timetabling Competition 2019 produced ranking second place at competition. Modeling program is not new. Our contribution rests o...

the paper discusses the current state of research concerning railway network timetabling and traffic management. timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. analytic (queuing) models and stochastic microsimulation are predominantly used for estimation of waiting times and ...

Finite Domain Programming is a technique for solving com-binatorial problems like planning, scheduling, connguration or timetabling. Inevitably, these problems employ disjunctive constraints. A rather new approach to model those constraints is constructive disjunction, whereby common information is lifted from the alternatives, aiming for stronger pruning of the search space. We show where cons...

The post-enrolment course timetabling (PE-CTT) is one of the most studied timetabling problems, for which many instances and results are available. In this work we design a metaheuristic approach based on Simulated Annealing to solve the PE-CTT. We consider all the different variants of the problem that have been proposed in the literature and we perform a comprehensive experimental analysis on...

The Course Timetabling Problem consists of the weekly scheduling of lectures of a collection of university courses, subject to certain constraints. The International Timetabling Competitions, ITC-2002 and ITC-2007, have been organized with the aim of creating a common formulation for comparison of solution proposals. This paper discusses the design and implementation of an extendable family of ...

The article presents a local search approach for the solution of timetabling problems in general, with a particular implementation for competition track 3 of the International Timetabling Competition 2007 (ITC 2007). The heuristic search procedure is based on Threshold Accepting to overcome local optima. A stochastic neighborhood is proposed and implemented, randomly removing and reassigning ev...

The Examination Timetabling problem regards the scheduling for the exams of a set of university courses, avoiding the overlapping of exams having students in common, fairly spreading the exams for the students, and satisfying room capacity constraints. We present a family of solution algorithms for a set of variants of the Examination Timetabling problem. The algorithms are based on tabu search...

Classical notions of disjunctive and cumulative scheduling are studied from the point of view of soft constraint satisfaction. Soft disjunctive scheduling is introduced as an instance of soft CSP and preferences included in this problem are applied to generate a lower bound based on existing discrete capacity resource. Timetabling problems at Purdue University and Faculty of Informatics at Masa...

E-mail : fabdennad,[email protected] Abstract : Timetabling the courses offered at the Computer Science Department of the University of Munich requires the processing of hard and soft constraints. Hard constraints are conditions that must be satisfied, soft constraints however may be violated, but should be satisfied as much as possible. This paper shows how to model our timetab...
