A load control system that communicates with existing automated meter reading communications systems to interrupt and shed loads at a customer location. The system includes a master controller that listens to communications between a utility meter and the reading system. The controller receives tier and / or pricing information and will instruct a load control unit to interrupt certain loads based on the information. In addition, the system may be employed as a load shedding system where a command may be forwarded to the master controller to disconnect loads based on action levels. The command may be sent via a TCP / IP communications system to a node in the reading system and the forwarded via a radio network to the master controller to reduce latency. Predictive shedding may be performed based on forecast loads.

A methodology of reducing process algebra to a language that facilitates modeling a business workflow process is provided. A process algebra is reduced to a model for business workflow processes. The model is then reduced to a scheduling programming language to allow users to create models of business process by selecting between features of the model and conventional modeling features. The scheduling programming language can be represented as a graphical user interface program that is convertible to a schedule language written in a programmable language. The present invention provides for explicitly representing parallelism within the business workflow process by separating interdependent transactions from independent transactions. The isolation of certain transactions are relaxed, such that users can define transactional boundaries in order to increase granularity of the transaction at an action level and provide visibility of transactions at intermediate steps.
