Model for a specific decision support system for crew requirement planning in ship management

Ship management has to face volatile business conditions, escalating volumes of information, and increasing complexity of company processes. Especially crewing, as one main task with significant fixed operating costs, imposes increasing demands for decision support. This contribution proposes a specific decision support system (SDSS) model for crew requirement planning for medium and large-sized shipping companies on an online analytical processing (OLAP) related structure. It gives a brief investigation of core information needs and associated basic data types before the model is developed. Additionally the underlying mathematical scheme and an appropriate user interface are depicted.
