Batch Schedules and Production Schedules Which Should You Use?
The integration of scheduling and control systems invariably involves custom programming or the use of proprietary formats to enable the transfer of production schedules. Currently there are two ISA standards committees developing standard schedule formats. The ISA SP88 committee's S88.02 draft 14 presents a batch schedule object model and a set of relational database tables for the exchange of schedule data. At the time this paper was written the ISA SP95 committee was finishing work on the S95.01 Enterprise/Control Integration standard1. S95.01 defines a production schedule object model. The SP95 committee is continuing work on this model as part of the S95.02 development effort. The committee is expected to develop attributes for the objects. This paper analyzes the two committee's work and proposes a mapping between the different sets of work. The mapping shows how the S88.02 schedule object model and exchange tables can fit into the S95.01 production schedule model and the on-going S95.02 work.
