abstract = {This paper presents a method for computing the costs of reconstruction of net models of concurrent systems described by information systems changing in time. Constructed net models have the form of coloured Petri nets. Resulting nets are constructed on the basis of decomposed information systems. In many practical cases, a description of modeled systems changes in time. A new knowledge about structures and behaviours of systems appears. When the new descriptions appear, we should change the net models taking into consideration the new knowledge. Sometimes, we want to know the costs of a reconstruction of such models. The cost of the reconstruction is treated as the cost of adding new functional modules, communication lines or their modifications.},
