The aim of carrying
out Operability Analysis is to highlight any issues that have a bearing
on the operability of a system/equipment. An Operability Analysis
should act designed for operation in the simplest and easiest way
possible.
Carrying out
an Operability Analysis involves the following:
|
•
|
Task Analysis |
|
•
|
Workload
analysis |
|
•
|
Human
reliability analysis |
|
•
|
Taking
due account of the prevailing environmental conditions |
An
Operability Analyses will:
|
•
|
Highlight
possible operability problems early in the design phase |
|
•
|
Provide
the means to remove operability problems from the design |
|
•
|
Instill
confidence in the finalised design |
|
•
|
Provide
a demonstration of the operability of new and /or modified systems |
Effort
invested in the Operability Analyses will vary with the criticality
of the equipment, its interfaces and interactions with other equipment.
Therefore the scope of operability assessments can be restricted
to a single task or cover a range of tasks.
It is preferable
that operability analyses are carried out during the design phase
to highlight problems early, when redesign is relatively easy. The
later in the programme the analysis is conducted, the greater the
time and cost implications will be for the project for any redesign
work. This may dictate several assessments at different levels of
detail as the project matures and a more detailed design becomes available.
Methods
|
•
|
Anthopemetrical
Studies can be used to provide known physical data on the population
to assess workplace layout and architecture. |
|
•
|
Rapid
prototype modelling permits varied configurations to be tested
over comparatively short timescales. This technique permits
feedback from subject matter expert to be incorporated into
the model, and assessed promptly, before possible inclusion
into the design. |
|
•
|
Task analysis
involves a study of the workforce (operators) to ascertain what
is required to achieve the system goals. This allows comparison
between the task demands and the operator's capabilities. |
|
•
|
Workload
analysis is an analysis of the demand placed on the operator
by the task requirements. |
|
•
|
Human
reliability analysis recognises the critical area where human
error may affect performance. |
|
•
|
Operational
scenario analysis is an analysis that the activities required
to be undertaken, can be successfully completed using the manpower
and facilities provided for the purpose. |
Could any of
these analyses techniques assist you to determine if there is a problem
with your system design?
Could the results
from these analyses assist you in significantly enhancing your system
safety.
