BATCH OBJECT MODELING AND LANGUAGE

Current SP88 work models Batch Objects in the diagrammatic notation pr omoted by Rumbaugh et al. This notation represents independent object elements and their possible relationships generally, with a different emphasis than object programming languages like C + +, whose objects a re built out of component objects. The notation models arbitrary objec t structures, but it blurs the essential (aggregation) hierarchy of th e Application Model and its component subObjects, with the inheritance hierarchy and other relationships. Like many first notations its comp lications need to be pared down to a rememberable set of three or four icons. This paper will use an equivalent, tutorial variant, for Proce ss Control Batch modeling and pairing down the concepts. The applicati on is modeled as a single whole with logical, Self-Similar, parts, div ided either in terms of the logical parts of the corresponding process , or in terms of the associated distinct control functions. This frame work emphasizes single applications, aggregated from parts. Inheritanc e of similar process or equipment subObjects are expressed by similar names or icons. This paper will outline the parts of a general Batch m odel and relate this model to the author's earlier language papers. (C ) 1997 Published by Elsevier Science B.V.
