Case Study: Highway Toll system Rules Fest – October 2010 – © Edson Tirelli 10

Case Study: Highway Toll system • Vehicles using the highway have their license plates scanned at entry and exit points • Charge is calculated based on: • Distance travelled • Type of vehicle • Day of the week, time of the day • Subscription plan (for frequent users) • Etc • For subscribers, usage is summarized and mailed as a monthly report • For non-subscribers, bills are summarized and mailed on a subscribers, weekly basis Rules Fest – October 2010 – © Edson Tirelli 11

Processes: apparent from the start Sample non-optimized process optimized Rules Fest – October 2010 – © Edson Tirelli 12

Ops… I need rules… Sample non-optimized process optimized Rules Fest – October 2010 – © Edson Tirelli 13

Rules for what? Type of Vehicle Day of the Week Distance (km) Charge per Km($) 0, 20 0.10 week day passenger 21, 200 0.08 weekend 0, 200 0.05 0, 10 0.23 truck week day 11, 30 0.21 31,200 0.19 … Sample Decision Table: rule abstraction for homogeneous : rules Rules Fest – October 2010 – © Edson Tirelli 14

Typical CEP solutions Event Processors Event Processors Event Processors Event Processors Event Processors Event Processors Application Streams Streams Streams Streams • Not flexible enough to meet the requirements for all scenarios: • Rules and processes need access to intermediate events as well • Event processing assets follow the same lifecycle of the rules and processes assets Rules Fest – October 2010 – © Edson Tirelli 18

What do we need? • BRMS is no longer enough • Business Knowledge Management • Takes into account all knowledge assets: • Models • Rules • Processes • CEP modules • etc • Provides a unified view and enables lifecycle management Rules Fest – October 2010 – © Edson Tirelli 19
