ABSTRACT
This chapter discusses two projects at the Dutch Railroad Company where people try to use the synergy of a multidisciplmary approach, and discusses this organisation and its planning domains, and issues related to what planners in practice in organisations in the context of empirical research. The two projects are interesting and promising in them and will therefore be continued, for example by investigating the consequences of the variety in domain views and problem solving behavior for planning support, and extensive experiments with various levels of planning support. A combination of cognitive science, computer science, and operations research resulted in a prototype planning system. In a number of research projects, the chapter analyses the planning of train shunting at the Zwolle station. The 'internal' DRC-view on planning is that planners have the same domain representations and reasoning structures. Basically the rolling staff planning follows the rolling stock planning that is realised in two ways.
