* * * * * * * * * The figure above is a simplified version of the Purdue model, showing the S95 scope. Level 4 is high level planning and scheduling and logistics. Level 3 is manufacturing control, including operations scheduling - or planning. Level 2 needs a lot of definition. Describe S88.01 and the batch model and how it stops at the process cell. Describe some of the S88.01 models. There are less well-defined models for continuous and discrete processes. Continuous is handled somewhat by S88.01, but without the concept of recipes for products, just recipes for product startup and shutdown. PDXI has a model at least of all of the static information (design of PIDs) and control loops, but not very dynamic Discrete models SME (Society of Mechanical Engineers has some material, but nothing in the ISA /IEC/ISO arena. * * * * Briefly list/discuss topics to be covered in this section. Duration: Spend approximately 1.5 hours on this section. * * * * * * * * * * * * One production schedule may encompass more than the scope of one control system. In this example the production schedule is broken into separate schedules for different types of packages. * * * * * * * The WBF Schemas based upon ISA-95 * * * * * * OAGi General Meeting ISA-95 - B2MML Briefing * May 2, 2006 Production Schedule Model Personnel Requirement Equipment Requirement Material Produced Requirement Personnel Model Equipment Model Material Model Corresponds to element in Corresponds to element in Corresponds to element in May contain 0..n 0..n 0..n 0..n 1..n Personnel Requirement Property Equipment Requirement Property Material Produced Requirement Property 1..n 1..n 1..n Production Schedule Process Parameter Material Consumed Requirement Corresponds to element in 0..n Material Consumed Requirement Property 1..n Consumable Expected 0..n Consumable Expected Property 1..n Segment Requirement 1..n Is made up of Is made up of Is associated to either Product Production Rule Requested Segment Response
