چکیده
We present a solution method for the liner shipping network design problem which is a core strategic planning problem faced by container carriers. We propose the first practical algorithm which explicitly handles transshipment time limits for all demands. Individual sailing speeds at each service leg are used to balance sailings speed against operational costs, hence ensuring that the found network is competitive on both transit time and cost. We present a matheuristic for the problem where a MIP is used to select which ports should be inserted or removed on a route. Computational results are presented showing very promising results for realistic global liner shipping networks. Due to a number of algorithmic enhancements, the obtained solutions can be found within the same time frame as used by previous algorithms not handling time constraints. Furthermore we present a sensitivity analysis on fluctuations in bunker price which confirms the applicability of the algorithm.

متن کاملAmbiguity, Identity Construction and Stress amongst Knowledge Workers: Developing Collective Coping Strategies through Negotiations of Meaning
The point of departure for the project “Preventing stress in knowledge work” is the realisation that in order to work on preventing stress amongst ‘knowledge workers’, a new understanding of the concept of stress and knowledge work is required. This paper explores how stress and associated mechanisms for coping in knowledge work can be understood both in terms of ambiguity, continuous identity ...
