For Utilities, each substation is regarded as an asset. Managing of assets is one of domains of Asset Management including Life Cycle Costing (LCC)
as a decision-making criterion. However, LCC as a decision-making criterion should be applied on an entire substation taking into account all of the
potential cost influences for the purpose of achieving of an effective substation management. Asset management as a decision-making process
should be observed within a larger context and should be more focused on risk management, as all real decisions include an element of risk due to
present uncertainties.
Two promising avenues are explored in regards to more comprehensive and rigorous up-front planning through usage of Information Technology
(IT). While up-front planning falls under the domain of Lean philosophy, Building Information Modeling (BIM) falls under the category of agile decisionsupport
tools. Utilization of both is explored from a perspective of design-uncertainties under both product and process design.
Standard specifications and standard designs are another form of applied Lean Philosophy that reduces design-uncertainty and variability. However,
a range of technical solutions stemming out of the standardization can be quite wide. Customization involves specification and design of new /
innovative designs with wide range of technical solutions as well. Due to external pressures focused on shortening of the project delivery time, there
is a need for a faster project time throughput. This is reflected in the form of a requirement for more rapid engineering decision-making and faster
decision cycles.
Streamlining of a decision-making process related to the engineering is all about engineers’ awareness of the situation from the project level perspective
coupled with utilization of decision-support tools for creation and reuse of knowledge. Plan – Do – Study – Orient (PDSO) cycle is a decisionmaking
model that supports creation and reusability of knowledge along with providing an explanation in regards to the time dimension relating to
decision-making, and as such is presented in this paper.
The rigid busbar system design is an iterative process influenced by many factors, defined either as design variables or design constraints. As rigid
busbars are gaining more popularity for both greenfield and brownfield investments, the rigid busbar system design is explored from a perspective of
decision-making streamlining. The case of the rigid busbar system design of El Chaparral project in El Salvador is given.
