摘要：AbstractAutomated production systems (aPS) have a long lifetime, which requires significant maintenance cost. During the commissioning phase of aPS, which often occurs at customer sites, the on-site engineers are always under high pressure because the customers would like to start the production at the earliest. There, some compromises, so-called technical debt (TD), might be chosen. A technical compromise taken in the commissioning phase can provide a short-term benefit, but could yield a long-term negative impact on the maintenance phase. This study aims to apply Causal Loop Diagram (CLD) to model technical compromises in the aPS domain. A concept, namely CLD+TD, is proposed. Application examples of CLD+TDon some technical compromises collected from an industrial company working in automation are reported. A loop dominance analysis on a CLD+TDmodel is performed to derive the circular trend of technical compromise over time; thus, relevant maintenance activities could be planned accordingly. In addition, challenges leading to the technical compromises addressed in the presented use cases can support practitioners in developing appropriate solutions to manage the reported technical compromises in the commissioning phase.
