IMPROVING THE PRODUCT CONTROL OF MECHATRONIC SYSTEMS USING KEY PERFORMANCE INDICATORS

Abstract

A product control process for complex mechatronic systems has to ensure high quality effectively and efficiently. However, due to the complexity, time-consuming post-assembly tests often lead to high quality costs. The contribution of this paper is a process and an assistance system for the product control of mechatronic systems, which significantly shorten the test duration. Hereto, we define key performance indicators (KPIs), which we use to analyze the product based on its sensor data. We implement our concepts at Diebold Nixdorf – a leading manufacturer of automated teller machines (ATMs) – and define seven ATM-specific KPIs. Moreover, we define a process for identifying and specifying KPIs for mechatronic systems. Finally, we report that our KPI-based product control at Diebold Nixdorf has the potential for a significant reduction in test duration and, therefore, quality costs while keeping at least the same quality level.
