automaton-simulation-de.rc
Models resource consumers interaction.
Resource definition:
- A limited quantity of items that are used (e.g. seized and disposed) by entities as they proceed through the system. A resource has a capacity that governs the total quantity of items that may be available. All the items in the resource are homogeneous, meaning that they are indistinguishable. If an entity attempts to seize a resource that does not have any units available it must wait in a queue. It is often representing real world items that availability is limited (e.g. machine, wrench).
Note:
- All namespaced keywords of the rc bounded context are from this namespace, so rc users need only to refer this one.

disposeclj/s
(dispose event-return
resource-name
{:automaton-simulation-de.rc/keys [resource]
:automaton-simulation-de.scheduler.event/keys [date]
:as _current-event})Returns the event-return with the resource disposed, so it is available again.
A consumer is unblocked, the capacity of resource-name is freed.
Returns the `event-return` with the resource disposed, so it is available again. A consumer is unblocked, the capacity of `resource-name` is freed.
preemption-policy-registryclj/s
(preemption-policy-registry)Returns the default registry for event preemption-policy.
Note that you can enrich it with your own policies.
Returns the default registry for event `preemption-policy`. Note that you can enrich it with your own policies.
resource-updateclj/s
(resource-update {:automaton-simulation-de.scheduler.event-return/keys [state]
:as event-return}
resource-name
new-capacity)Update the resource capacity.
Update the resource capacity.
seizeclj/s

resource-name
consumed-quantity
seizing-date
postponed-event)Seize a resource,
Depending on the capacity found in the state for that resource-name,
- If capacity is not defined for that resource, the whole consumption is skipped, including the
postponed-eventexecution. - If some resource are available, the
postponed-eventis executed now, (i.e. added at the current date in the scheduler) - Otherwise block that consumer and store it in the queue
- Blocked consumer: A blocked consumer is a consumer waiting for a resource being available.
- Queue: Stores blocked consumers.
Returns an event-return.

(unblocking-policy-registry)Returns the default registry for event unblocking-policy.

Returns the default registry for event `unblocking-policy`. Note that you can enrich it with your own policies.
wrap-modelclj/s
(wrap-model model resources)(wrap-model model
resources
unblocking-policy-registry
preemption-policy-registry)Wraps a model to add necessary behavior to model a resource/consumer.
The resources is a map defining the resource available:
* policy In a queue, the policy selects the next consumer that will be unblocked. (Each queue has its own policy)
* renewable? When disposed, a renewable resource model is available again. Typically the toolings like wrenches, hammers, machines are most often renewable resources.
