Remote condition monitoring (RCM) of machines seeks to enhance proactive maintenance through just-in-time responses to machine faults and process deterioration. This approach offers the benefit of reduced manning of machines and robust joint maintenance decisions, due to remote access to the machines' condition. This paper employs a remote condition monitoring approach to two elevator parameters, vibration and machine room-temperature, using an Internet of Things (IoT) device for remote data acquisition and remote fault indication. A remote monitoring set-up was developed that uses augmented sensors, networked connections, and an Arduino Yun microcontroller installed on the elevator system to monitor remotely any deterioration in its working condition. The set-up was configured to monitor the conditions online remotely through an email application service. The data from the email were analysed, and notifications were generated at the machine's severity level. The result showed that RCM enables faster repair and maintenance decisions, prevents the catastrophic breakdown of machines, and serves as a troubleshooting guide for fault diagnosis.

2024 had come to an abrupt end, and this is the final edition for 2024. At the end of 2023, we were still living with the effects of COVID, and continuous load shedding. But life had moved on! Load shedding is (for now at least) history. South Africa had elections in 2024, and a new Government of National Unity was established, and with that, a lot of new optimism about the future! Logistics and the broken rail network are still issues, but you can see how industrial engineering professionals are adapting to these new challenges to find solutions. As mentioned at the end of 2017, it is now customary to evaluate how the journal is performing. Scopus (www.scopus.com) measures impact with a “CiteScore”. The CiteScore for a year is calculated as the Citation Count for the year / number of documents published in the previous three years. The Citescore for 2022 was 1.4, in 2023 it was 1.1 and 2024 is projected to be 1.2 . Our ranking with respect to the Percentile in the category, is currently stable as a Q3 journal. Another important source for journal standing, is Scimago Journal and Country Rank (www.scimagojr.com), where the journal is also listed as a Q3 journal in the “Industrial and Manufacturing Engineering” subject area. It is very encouraging to observe how the number of citations per document has grown (Figure 1).

The unmanned aircraft system (UAS) industry in Indonesia is lagging behind in market share and innovation. An effective government policy is crucial to make domestic UAS products more innovative and competitive. However, still not enough academic research discusses the system structure of the UAS industry. Considering the complexity of the UAS industry, this study uses system dynamics in combination with a policy analysis framework to capture a broader perspective on the system. The conceptual model showed that a policy structure to shift customers from imported products to domestic products may help the development of the UAS industry and advance UAS technology.

This scoping review provides an expanded view of the Agile methodology in the software industry - an iterative, incremental project management framework that is renowned for its use in software development. Research questions covering the advantages, disadvantages, enablers, and barriers to Agile were formulated to analyse accepted research papers from 2019 to 2023. Notable overlapping findings were found in the 25 studies that were included. The results revealed that human factors such as communication, conflict resolution, and understanding Agile are essential to the successful implementation of Agile software development.

Masked stereolithography is an effective and economical additive manufacturing technology that is suitable to fabricate objects for engineering applications. As such, parametric optimisation to attain good mechanical properties is of value in order to realise its full potential. A multi-objective optimisation of the printing parameters of masked stereolithography 3D printing for mechanical properties was performed using central composite design for response surface method analysis. The developed response surfaces were used to perform numerical optimisation to establish appropriate printing parameters, which were validated against experimental results and compared with bulk polymer specimen mechanical properties. Here, an optimised layer cure time of 3.8 s, a layer height of 50 μm, and a post-curing time of 13.5 min resulted in mechanical properties closely predicted by the model and near to bulk polymer specimen properties. Last, the optimisation results were related to a Jacobs working curve, which established that layer cure times beyond that determined by the Jacobs working curve were favoured.

Local government municipalities have not only authority and functionality but also the responsibility to carry out their duties in difficult circumstances. In addition, the current state of operations management and its influence on municipality service delivery is largely limited or undefined. Consequently, this study’s purpose is to assess the operations management factors that affect service delivery in a local municipality in South Africa. The aim of this study was to help the management of municipalities to gain a better understanding of the influence of operations management and the degree to which operations management factors affect service delivery. The study used a positivistic lens, and adopted an online survey instrument to solicit information from respondents in a municipality in South Africa. The findings revealed a significant and positive correlation between operations management factors and service delivery. Therefore, the management of municipalities could enhance their organisations’ performance and service delivery by implementing an effective operations management system and by considering the factors developed by this study.
