Decision Support Tools

Among the many deliverables of the SALVO  project is a suite of highly innovative decision support tools. These are modular 'what if?' evaluators for a wide range of decision types and possible interventions. They enable instant exploration of cost/risk/performance trade-offs, short term versus long term and life cycle effects, the impact of data uncertainty, and the economic value of intangibles or constraints.

The SALVO software tools are called the DST Strategy Evaluator suite and have been developed by some of the top international experts in reliability, risk, life cycle and economic modelling. They represent the leading edge in comprehensive decision support, and all algorythms and modules have been independently validated by the University of Cambridge. They also incorporate the guided thinking and human psychology that emerged from the SALVO research. The credibility of the results rests on how the underlying information is obtained, how tacit (expert) knowledge is safely captured, quantified and used, and how results are presented in an easy-to-understand format.

The Decision Support Tools (DST) modules and the types of decisions that they support include:

 dst_projectchangeevaluator  

Physical changes to assets (‘step-change’ modifications) OR any changes in procedures, competencies, mitigation options etc.

 dst_lifespanevaluator  

Asset replacement decisions, optimal renewal timing, obsolescence management options, refurbishments to extend life, new asset design options (life cycle cost evaluation).

 dst_inspectionevaluator  

Condition monitoring, periodic inspections, predictive maintenance strategies AND/OR functional testing (for hidden failure modes) & optimal intervals.

 dst_maintenanceevaluator  

Preventive maintenance justification, optimal planned maintenance intervals, corrective maintenance, performance/efficiency improvements, life extension activities (e.g. painting, lubrication).

 dst_inventoryoptimzer  

Optimal spares, inventory and materials, supply chain and purchasing options, operational stand-by and redundancy options.

 dst_scheduleoptimizer  

Optimal work bundling, shutdown strategy & intervals, remote site visits (work scopes and intervals), opportunity-based projects, maintenance or renewals.

 dst_stamp  

Strategic Asset Management Planning: assembly of timing-optimized and resource-coordinated activities for their combined Capex & Opex, risks, performance and resource implications.

 

Decision 'storyboards'

The DST modules guide you through comprehensive, step-by-step storyboards for over 40 typical decision types. These are designed to assist multi-disciplined teams to follow the SALVO process, build a full picture of the cost, risk, performance, life cycle and other factors involved in each decision, and to explore, in real time, the effects of different assumptions, scenarios and conflicting opinions.
