Topic 8.1.1: Overview

  • The Batch Management System consists of scheduling, initializing, interfacing with operators, directing batch activity to the historical database, and coordinating the execution of batches with the control system.
  • The functions provided by the Batch Manager, Batch Scheduler, and Batch Display applications. The result is a flexible, reliable, and intuitive approach to managing batch processes.
  • Scheduling – The Batch Scheduler's capability is that of dispatching ready-to-run batches, to plant floor operators. Scheduling involves the manual entry of the batch identification, master recipe identification, quantity to be produced, and Train  identification into the schedule dialog box. Once entered, the batch can be initialized.
  • Initialization – Each batch must be initialized before it can be executed. The initialization process involves validation of the recipe, and verifying that the Train exists, the bulk materials defined in the recipe are found in the Materials database, the recipe equipment requirements are satisfied by the Train, and the Process Model database is compatible with the recipe. Initialization is performed from the Batch Scheduler.
  • Batch and Unit Management – The Batch Manager directs and supervises the execution of each batch. The Batch Manager is a recipe interpreter and control system enabler. Based on the recipe procedure, and blocks of control software, (referred to as phases), are signaled to execute by the Batch Manager.

  • History – The Batch Manager captures all batch execution events and operator activity during the execution of a batch and sends this information to the historical database.
