Los Angeles Department ofWater & Power is the largest

municipal utility in the nationservicing an area of over 465square miles

GE iFIX helps to: Maintain more than 7200 miles of water

pipelines

Monitor more than 100 Reservoirs and

Tanks, 400 Regulator Stations, 70 PumpStations and 30 Treatment Stations

Deliver 513 million gallons of clean waterevery day to more than 4 million people


9/53

WHAT THIS TRANSLATES TO:

Over 60,000 Data Tags monitored every

day across Field HMIs, Water Transmission SCADA & WaterTreatment SCADA

Generating on average 1200 alarms a day

High Performance HMIs

Help our Operators visualize a process

Quickly determine an abnormal situation

Topographical HMIs

Help our Operators visualize system areas

Important when moving wateracross a large city

Schematic Process Style HMIs

Help our Operators find the root cause

and isolate issues in the field Important when working with many

different types of facilities

Information overload!

Alarms?

Packed information

ConfusingVisual coding

27/53

What is the Problem?

Easy to put more information on the screen & provideoperators with lots of data

Easy to create alarms operators get flooded

Graphics over substance 3D, realistic views

Difficult to identify issues

Operators are not as efficient as they could be.


28/53

Best HMI design practicesGreat design for a better User Experience

Operators should be able to recognize whichinformation needs their attention and what itindicates

at a glance

Why Change?

Poor HMI design principles can lead to:

Safety Issues

Accidents

Increased response time

Prolonged downtime

Human centered design approachResearch, design and validation with

100+ operators in 21 plants in 5 countries

The UX design process:

Discovery

Concept design, evaluation Design & Prototyping

User validation & assessment

What makes a good operator interface from anOperator perspective?

35

SIMPLE INTUITIVE

CONFIDENT SEAMLESS

Recognize andunderstand informationwith ease and speed

Anticipate andrecognize issues

quickly, and respondinstantly

Have confidence in the

control system

Complete their tasks

and navigateseamlessly


35/53

Structural Elements


36/53

Minimalism

Too much information

Hard to detect process status


37/53

Minimalism

Less content improves detection

Show details only to put data in context


38/53

Color palette

Too much color is distracting

More color increases operator cognitive workload


39/53

Color palette

Use color to draw attention

Less color = less operator cognitive workload


40/53

Visual Coding

Many different visual coding techniques

Slows visual recognition


41/53

Visual Coding

Meaningful, consistent , shapes & colors

Contrast for easy detection


42/53

Information Layout

P&ID presentation vs. process control

Lack of information layout strategy


43/53

Information Layout

Process-oriented presentation Consistent layout Utilize P&ID-like details for lower level screens


44/53

Contextual Data

Information overload

Need to search for critical data


45/53

Contextual Data

Data in context to process

Critical data aided by visual representation


46/53

Navigation

Visual cues are for process awareness Unclear parent-child structure Interaction is not intuitive


47/53

Navigation

Intuitive organization

Mixed approaches most flexible


48/53

Alarm Presentation

Process alarms mingled with system alarms Criticality hard to determine Readability issues


49/53

Alarm Presentation

Easy to understand alarm presentation Process alarms to the operator System alerts to the maintenance technician

SUMMARY - 9 Design Principles

Minimalism

Color palette

Visual coding

Information layout

Contextual data

Embedded trends

Screen hierarchy

Navigation

Alarm presentation

With a glance, operators should be able to recognize whichinformation requires more attention and what it indicates.

Improves detection

Decreases cognitive workload

Increases speed of recognition

Provides intuitive, process-oriented views

Reduce information overload

Provide more information when its useful

Reflects the operators mental model

Enables quick, intuitive way-finding

Enables faster detection and understanding
