Abstract: In an embodiment, a computer-based method for automatically selecting resources to include in a building plan layout is disclosed. The method involves obtaining a set of resource rules that define resources placeable within a building plan layout, obtaining a set of behavioral rules that define the behaviors of the resources, generating a model by evaluating the set of resource rules and the set of behavioral rules, obtaining a configuration, wherein a configuration comprises at least one of building demand, resource permutations, and other simulation attributes, generating at least one set of performance metrics by executing the model with the configuration, storing the at least one set of performance metrics, the model, and the configuration as an entry in a metrics database, selecting an entry from the metrics database, and outputting the entry to a building plan layout generator.

Abstract: In accordance with an embodiment of the invention, a discrete event simulator is disclosed. In an embodiment, the discrete event simulator includes a model having at least one activity instance, wherein the at least one activity has an activity type that defines a participating entity type list and a duration of time over which the activity instance will be performed, at least one activity queue, wherein the at least one activity queue is configured to hold the at least one activity instance in an order, and at least one entity, wherein the at least one entity is associated with at least one behavior and is configured to join at least one activity instance, and a configuration, wherein the configuration further defines the at least one entity, wherein the at least one entity is configured to perform the at least one associated behavior when, upon joining the at least one activity instance, an entity for each type in the participating entity type list of the activity instance has joined the activity instance.

Abstract: Traffic through a portion of a city formed of streets defining a grid includes clusters of traffic signs, each cluster being positioned at an intersection and having its own cluster process controller. The clusters also include cameras monitoring traffic through and at each intersection. The cameras provide information used locally or at remote localities to control traffic. The remote localities may include a traffic command center, fire/police stations or a home security office.

Abstract: System and method for dividing an input frequency to produce an output frequency related to the input frequency by a non-integral ratio. The divider ratio is alternated between the integer values bracketing the non-integer ratio according to the accumulated value of known errors associated with each integer divisor value by comparing the accumulated error value to a given value.
