Alternative structure ( without working top )

Data transfer Select one or more replicas Select action to perform Apply

Application problem Work orders in separate alternatives Changes must be posted to top to be transferred to another laptop ~1600 work orders (alternatives) conflicts

Solution Managing time and change in Smallworld GIS, presented by Peter Batty at Smallworld ’95 geometry mapped by construction status join table links objects with work order We now have ~70 alternatives

Mapped Geometries Mapped geometry based on construction status Existingregular geometry Remove Placesimple geometry Not in service Remove – not in service

Geometries have their own style and database priority. Normal viewing ACE does not show proposed objects. Custom draw methods are used so that only objects pertaining to the current work order will be displayed.

OMS - PowerOn Visual Basic Interface Oracle Database Fast Access With each outage, affected customers can be easily identified. Improved flow of information between Customer Service and Dispatchers Outage Management System

Outage Management Process Customer reports outage to Service Center Call entered in CIS Trouble Analyzer retrieves trouble call from CIS and passes to PowerOn PowerOn uses prediction rules and electrical connectivity information to predict the device causing outage Outage project is created in PowerOn

PowerOn User Interface

Outage Properties

Predicted Outage Predicted Faulted device Customer that has called in with no Power

Business Perspective Allows for Resource Management Crew and equipment management Provides an accurate total number of customers off - helps dispatchers prioritize Provides information back to CIS Customers automatically get the correct status message based on network model Closing a project can resolve whole sets of customer outage reports Automate history and eliminate paperwork and filing
