21 PROPERTIES OF PROCESSES: Efficiency/Productivity Efficiency with respect to a given resource is the ratio between the cardinality ratio of the product and the cardinality ratio of the resource –For higher order relationships, the cardinality ratios of other resources are held at a fixed level PROCESS Product Produce 1 or more use 1 or more [used by 0 or more] [produced by 0 or more] Resource Divide by Efficiency Cycle Time Divide by Productivity
22 PROPERTIES OF PROCESSES: Capacity Temporal capacity: similar to non-temporal capacity –Cardinality upper bounds: Limited capacity to produce product or use resource –May vary by object class, instance or time slice or any combination of these Eg: an instance of a razor blade engaged in a shaving process cannot be used by any other process concurrently (capacity for concurrent engagement) Eg: A Person may concurrently be engaged in a maximum of 4 projects at a time (capacity for concurrent engagement) Eg: Razor blade may be good for only 5 shaves (Capacity for repetition) – How much of a resource is engaged or consumed is normalized by the “use” relationship between the resource and the process What kind of capacity is normalized by the “produce” relationship? Is a process a polymorphism of a product? Is the product a polymorphism of a goal?
