Design Decision 4: Rationale/Impact

One Oven Controller OC for multiple Ovens:

• A shared controller is chosen to gain experience with inter-dependent and sharable components.

• The alternative of independent Oven Controllers, one per oven, is today’s sensible and reliable solution (cheap microprocessors can run simple control programs).

• However, these would not reveal problems caused by inter-object dependencies via a shared controller. These are more likely to occur when the problem is scaled up to process control systems (e.g. the Juice Plant JPsim).
