    An index based method for estimating the effect of process configuration on inherent safety has been presented. Process configuration means which operations are involved in the process and how they are connected together. An inherently safe process structure is not possible to define by explicite rules, but one has to rely on standards, recommendations and accident reports. When problem solving is based on experience it is possible to use case-based reasoning. Therefore CBR was employed for determining the value of safe process structure subindex. For this purpose a casebase of accident cases and recommended designs was created. A case can be retrieved on five levels of aggregation (from process to detail) from the casebase to ensure the relevancy of retrieved information in various phases of preliminary process design.
