A process in which participants in different situations define in plural epistemological spaces can be easily accommodated. An epistemological space synthesizing part synthesizes different epistemological spaces to generate a new epistemological space, thereby juxtaposing therein business processes defined in each of the epistemological spaces. An accommodated activity extraction part extracts a combinable activity from the activities of the combined business process. A common resource extraction part extracts a combinable resource (common resource) used or produced by the extracted activity. A pre- and post-activity extraction part extracts pre- and post-activities to be accommodated. A combined business process generation part generates a business process which automatically synthesizes combinable parts from the juxtaposed business processes. An accommodating activity extraction selection part uses information acquired by the accommodation information extraction part to present an accommodating method. A user selects a suitable accommodating activity.
