A framework for modelling in S88 constructs for scheduling purposes

ISA S88.01 [1] [ISA (ANSI/S88.01.1995), Standard batch control; part 1: models and terminology, Instrument Society of America, 1995] is a standard that provides a methodology for the dissemination of a batch into standard models and provides the terminology for defining the control requirements of batch plants. The nature of S88 is such that it is not only applicable to the development of computer control systems for a batch plant, but also could be utilised within batch management software, i.e. scheduling. This paper presents a method of interpreting multi-purpose/product batch plant into S88 constructs to provide an object oriented framework for the research and development of a batch scheduling Matlab toolbox. Such a framework provides a thorough and efficient method of articulating the model to effectively apply automatic scheduling/optimisation methods.
