How to end a subtask A BATCHES simulation model consists of three building blocks: Equipment Network, Recipe Network and Production Controls.
The equipment network defines the equipment specifications and connectivity constraints. Equipment network represents the physical model of the process. Depending on the scope of a model, it may consist of one piece of equipment from a given facility to all pieces of equipment from multiple facilities. Random breakdown of equipment and scheduled maintenance can also be modeled.
The recipe for the manufacture of a product is modeled as a network of tasks, and each task as a sequence of subtasks. The network graphically represents the sequence of steps and interactions between various operations. The details of each step are specified through the various dialog boxes. A recipe can be modeled down to the finest detail. You can control the level of detail through the choice of a suitable model that best represents the physical/chemical changes occurring during each subtask. Other subtask parameters available for detailed recipe specification are:
Material input and output requirements
Operator and utility
requirements
State dependent logic execution
Conditional Branch specification
The Production Controls allow you to specify information that drives the process, for example, the amounts and sequence in which various products are made, the due date and amount for finished product deliveries. Additionally, the amounts and frequency of raw material arrivals can be specified, and the state of equipment can be set to match the process status at a specific time.
