In this paper we propose a two-phase approach to solve the shift and break design problem using integer linear programming. In the first phase we create the shifts, while heuristically taking the breaks into account. In the second phase we assign bre

This paper introduces a shift rostering problem that surprisingly has not been studied in the literature: the weekend shift rostering problem. It is motivated by our experience that employees' shift preferences predominantly focus on the weekends, si

This paper studies a two-phase decomposition approach to solving the personnel scheduling problem. The first phase creates a days-off-schedule, indicating working days and days off for each employee. The second phase assigns shifts to the working day

In this paper we propose a neighbourhood structure based on sequential/cyclic moves and a cyclic transfer algorithm for the high school timetabling problem. This method enables execution of complex moves for improving an existing solution, while deal

It is increasingly recognized that material surface topography is able to evoke specific cellular responses, endowing materials with instructive properties that were formerly reserved for growth factors. This opens the window to improve upon, in a co

We describe the problem of intermodal international freight transport that is faced by some logistic service providers and the solution that ORTEC’s logistic suite offers to these customers. This solution is based on a state of the art k -shortest

This paper describes an approach in which a local search technique is alternated with a process which ‘jumps' to another point in the search space. After each ‘jump' a (time-intensive) local search is used to obtain a new local optimum. The focus

Given n clubs with two teams each, we show that, if n is even, it is possible to construct a schedule for a single round robin tournament satisfying the following properties: the number of breaks is 2n−2, teams of the same club never play at home s

We consider the break minimization problem for fixing home–away assignments in round-robin sports tournaments. First, we show that, for an opponent schedule with $n$ teams and $n−1$ rounds, there always exists a home–away assignment with at mos
