The design of a semantics-oriented organisational performance measurement system

Current methods and techniques used in designing organisational performance measurement systems do not consider the multiple aspects of business processes or the semantics of data generated during the lifecycle of a product. In this paper, we propose an organisational performance measurement systems design model that is based on the semantics of an organisation, business process and products lifecycle. Organisational performance measurement is examined from academic and practice disciplines. The multi-discipline approach is used as a research tool to explore the weaknesses of current models that are used to design organisational performance measurement systems. This helped in identifying the gaps in research and practice concerning the issues and challenges in designing information systems for measuring the performance of an organisation. The knowledge sources investigated include on-going and completed research project reports; scientific and management literature; and practitioners’ magazines.

Versatile and easy-to-assemble measurement system for impedance-based structural health monitoring

In this paper we present a versatile and easy-to-assemble measurement system for structural health monitoring (SHM) based on the electromechanical impedance (EMI) technique. The hardware of the proposed system consists only of a common data acquisition (DAQ) device with external resistors and allows real-time data acquisition from multiple sensors. Besides the low-cost compared to conventional impedance analyzers, the hardware and the software are simple and easier to implement than other measurement systems that have been recently proposed.

A Measurement System Experiment to Evaluate the Nosing-to-nosing Method for Measuring Dimensions of Steps

Non-uniformity of steps within a flight is a major risk factor for falls. Guidelines and requirements for uniformity of step risers and tread depths assume the measurement system provides precise dimensional values. The state-of-the-art measurement system is a relatively new method, known as the nosing-to-nosing method. It involves measuring the distance between the noses of adjacent steps and the angle formed with the horizontal. From these measurements, the effective riser height and tread depth are calculated. This study was undertaken for the purpose of evaluating the measurement system to determine how much of total measurement variability comes from the step variations versus that due to repeatability and reproducibility (R&R) associated with the measurers. Using an experimental design quality control professionals call a measurement system experiment, two measurers measured all steps in six randomly selected flights, and repeated the process on a subsequent day. After marking each step in a flight in three lateral places (left, center, and right), the measurers took their measurement. This process yielded 774 values of riser height and 672 values of tread depth. Results of applying the Gage R&R ANOVA procedure in Minitab software indicated that the R&R contribution to riser height variability was 1.42%; and to tread depth was 0.50%. All remaining variability was attributed to actual step-to-step differences. These results may be compared with guidelines used in the automobile industry for measurement systems that consider R&R less than 1% as an acceptable measurement system; and R&R between 1% and 9% as acceptable depending on the application, the cost of the measuring device, cost of repair, or other factors.

Vergleich von Performance Measurement-Systemen zum Einsatz für die Kommissionierung

Aufgrund sich schnell verändernder Anforderungen des Marktes sind Unternehmen ständig dazu aufgefordert, ihre eigenen Prozesse und Strukturen zu überdenken und ggf. anzupassen. Von diesen Entwicklungen ist auch die Kommissionierung als Teil eines Intralogistiksystems betroffen. Um allerdings geeignete Maßnahmen ergreifen zu können, müssen Systemleistungen und –kosten permanent gemessen werden. Hierzu eignet sich der Einsatz von Performance Measurement-Systemen als Weiterentwicklung traditioneller Kennzahlensysteme. In diesem Beitrag werden verschiedene Performance Measurement-Systeme gegenüber gestellt und hinsichtlich ihrer Eignung für den Einsatz in Kommissioniersystemen bewertet. Auf Basis der Ergebnisse der Bewertung erfolgt eine erste Konzeption eines Performance Measurement-Systems für die Kommissionierung unter Verwendung typischer Kennzahlen, die in der Literatur genannt werden. Abschließend werden Hinweise zur noch notwendigen detaillierten Umsetzung und Evaluation in der Praxis gegeben.
