The influence of information quality on decision-making for networked infrastructure management

Abstract

Operational decision processes for networked infrastructure management often occur as a multi-actor planning problem, implying these are partly based on negotiations between different stakeholders. The starting point for negation for each stakeholder is the available information about the structural condition of his infrastructure. In this respect, this leads to the question: ‘does more accurate data about actual structural condition lead to other or better decision-making?’ A serious game is introduced, ‘Maintenance in Motion’, aiming at investigating the influence of information quality about structural condition on replacement decisions, for single and multi-actor decision-making. Players are challenged to balance their individual goal, cost-effectiveness, with their team utility, increasing overall infrastructure quality to minimise failure while minimising overall public costs. Results show that if players are presented with perfect instead of imperfect information, in a single player environment, they played more cost-effectively. The availability of perfect instead of imperfect information about object state hardly changes game outcome in terms of team utility. It means collaborative choices for team utility are primarily based on negotiations that lead to compromises, instead of analytical reasoning as a group. This indicates that efforts in improving decision-making by improving information quality are only partly effective.
