“…Applications of KBS in maintenance include developing intelligent product manuals (Setchi et al 2006), the development of an environmental DSS to improve the operation and maintenance of constructed wetlands (Turon et al 2007) and a KBS for maintenance planning of highway concrete bridges (Chassiakos et al 2005). In fault diagnosis, KBSs are used in implementation of knowledge maintenance modules in an expert system for fault diagnosis of chemical process plants (Qian et al 2005), fault diagnosis of a chemical process operation, real time fault diagnosis of a lubricating oil refining process (Qian et al 2008), a Web-based hydro turbine fault diagnosis system (Song et al 2008) and in motorcycle maintenance (Su et al 2006).…”

Purpose: The use of AI for operations management, with its ability to evolve solutions, handle uncertainty and perform optimisation continues to be a major field of research. The growing body of publications over the last two decades means that it can be difficult to keep track of what has been done previously, what has worked, and what really needs to be addressed. Hence this paper presents a survey of the use of AI in operations management aimed at presenting the key research themes, trends and directions of research.Design/methodology/approach: The paper builds upon our previous survey of this field which was carried out for the 10 year period 1995 to 2004(Kobbacy et al. 2007. Like the previous survey, it uses the Elsevier's ScienceDirect database as a source. The framework and methodology adopted for the survey is kept as similar as possible to enable continuity and comparison of trends. Thus the application categories adopted are: (a) design, (b) scheduling, (c) process planning and control and (d) quality, maintenance and fault diagnosis. Research on utilising neural networks, case based reasoning, fuzzy logic, knowledge based systems, data mining, and hybrid AI in the four application areas are identified. Findings:The survey categorises over 1400 papers, identifying the uses of AI in the four categories of operations management and concludes with an analysis of the trends, gaps and directions for future research. The findings include: (a) The trends for Design and Scheduling show a dramatic increase in the use of GAs since 2003-04 that reflect recognition of their success in these areas, (b) A significant decline in research on use of KBS, reflecting their transition into practice, (c) an increasing trend in the use of fuzzy logic in Quality, Maintenance and Fault Diagnosis, (d) surprising gaps in the use of CBR and hybrid methods in operations management that offer opportunities for future research.Originality/value: This is the largest and most comprehensive study to classify research on the use of AI in operations management to date. The survey and trends identified provide a useful reference point and directions for future research.

“…However, rulebased systems struggle to cope with missing data such as when one or more input conditions are unknown. Although various schemes have been employed to get around this, for example Song et al (2006), these are generally of an ad hoc nature. For our system, we have instead chosen to adopt a method which permits the combination of expert opinion and data, and which uses probability theory to represent uncertainty, that is Bayesian networks (BNs).…”

Intense competition and the requirement to continually drive down costs within a mature mobile telephone infrastructure market calls for new and innovative solutions to process improvement. One particular challenge is to improve the quality and reliability of the diagnostic process for systems testing of Global System for Mobile Communications and Universal Mobile Telecommunications System products. In this paper, we concentrate on a particularly important equipment type-the Base Transceiver Station (BTS). The BTS manages the radio channels and transfers signalling information to and from mobile stations (ie mobile phones). Most of the diagnostic processes are manually operated and rely heavily on individual operators and technicians' knowledge for their performance. Hence, there is a high cost associated with troubleshooting in terms of time and manpower. In this paper, we employ Bayesian networks (BNs) to model the domain knowledge that comprises the operations of the System Under Test, Automated Test Equipment (ATE), and the diagnostic skill of experienced engineers, in an attempt to enhance the efficiency and reliability of the diagnostic process. The proposed automated diagnostic tool (known as Wisdom) consists of several modules. An intelligent user interface provides possible solutions to test operators/technicians, captures their responses, and activates the automated test program. Server and client software architecture is used to integrate Wisdom with the ATE seamlessly and to maintain Wisdom as an independent module. A local area network provides the infrastructure for managing and deploying the multimedia information in real time. We describe how a diagnostic model can be developed and implemented using a BN approach. We also describe how the resulting process of diagnosis following failure, advice generation, and subsequent actions by the operator are handled interactively by the prototype system. The results from an initial survey are presented, indicating sizeable reductions in fault correction times for many fault types.

“…Among the existing monitoring subsystems of the integrated monitoring system of HGSs, the vibration monitoring system is the most basic part, which plays an important role in ensuring the safety of HGSs [9], [10]. Therefore, it is significant to improve the vibration monitoring ability of the integrated monitoring system of HGSs.…”

Vibration monitoring is the most important module of an integrated monitoring system of hydroelectric generating sets (HGSs) due to the fact that most faults of HGSs are reflected in the form of vibration.To improve the vibration monitoring ability of the integrated monitoring system of HGSs, a novel integrated monitoring approach based on team intelligence is proposed in this paper. The monitoring functions are assigned to some team members with complementary capabilities and expertise, based on which the integrated monitoring framework of HGSs is established. The vibration state data are divided into five layers, for which selective storage strategies are proposed to improve the pertinence of the data and save storage space. In addition, real-time and time-lapse cooperative monitoring are realized with the driving of condition synchronization, event synchronization and time-lapse inspections. Meanwhile, the selective storage and associative storage of the state data are completed during the process. Besides, the temporary data continuously stored can be extracted and permanently stored by experts to prevent the omission of selective storage. Currently, the proposed approach has been successfully applied in Gezhouba Hydropower Station, which significantly improves the intelligent level of the power station.
