Objectives for GIS Project

• Improve Customer Service• Improve Employee Productivity• Provide Better Facilities Information• Make Information More Accessible

History

• 1993 Feasibility Study• 1994 Chose Smallworld• Developed Data Model & Data Collection• 1994-1998 Data Collection• 1995 Began Developing Applications

History

1994 - 1998 Field Data Collection• Co-developed application with Blue Marble• Utilized BM’s GeoView (Visual Basic/Access)• Developed software to load into Smallworld• Used internal Field Engineers and Linemen

• Utilized Trimble ProXL GPS for collecting meter locations

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

• Existing regular geometry• Remove

• Place simple 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 pertainingto 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

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
