The operation and maintenance management of telecom platforms puts more emphasis on operation and alarm monitoring and less on business flow, and it is difficult to have a seamless connection between operation and maintenance and sales. To improve the cooperative efficiency and the informatization level of telecom platform operation and maintenance, a new operation and maintenance system integrating Apriori association rules for a telecom platform is proposed. In this paper, the Apriori algorithm is firstly used to analyse the fault correlation of the operation and maintenance system of the telecommunications platform to get the alarm message. Then, the fault risk of the operation and maintenance platform is evaluated intelligently by the system-business alarm causality model. Finally, based on the fixed end and the mobile end, the dynamic presentation of the system running state and alarm monitoring, device query and positioning, and online and offline inspection are implemented and designed, respectively. Experimental results show that the proposed operation and maintenance systems integrating Apriori association rules for the telecom platform innovate the cooperative mode between the operations and sales team, and the average time reduces to 3.9 minutes from 4.7 minutes and the risk forecasting accuracy increases from 8% to 26%. The assumed method can significantly improve the operational efficiency and intelligent level of the telecom platform’s system and business.

According to the International Safety Management Code, every cargo ships of 500 gross tons and over must establish Ship Safety Management System that is documented in a Safety Management Manual. This document is prepared by the Company and contains rules regarding maintenance of the equipment, particularly recognized critical equipment. Those rules must be included into ship’s Planned Maintenance System, another requirement of the ISM Code. Maintenance periods in rules are based on several factors, while the Company experience in the operation and maintenance of the ship and its machinery and equipment is emphasized and analyzed in this paper. Analysis of records from different Computerized Planned Maintenance Systems obtained from several companies show that each company implemented their experience in the system. At the same time, the results show that very few modification of machinery maintenance intervals have been made with the proactive approach based on acquired experience and new knowledge.

Abstract For modern operation and maintenance systems, they are usually required to monitor multiple types and large quantities of machine’s key performance indicators (KPIs) at the same time with limited resources. In this paper, to tackle these problems, we propose a highly compatible time series anomaly detection model based on K-means clustering algorithm with a new Wavelet Feature Distance (WFD). Our work is inspired by some ideas from image processing and signal processing domain. Our model detects abnormalities in the time series datasets which are first clustered by K-means to boost the accuracy. Our experiments show significant accuracy improvements compared with traditional algorithms, and excellent compatibilities and operating efficiencies compared with algorithms based on deep learning.

Substation Equipment

The maintenance of substations is crucial for the safety of the electrical grid and power industry.<strong> </strong>However, for long time, the maintenance teams in the field and the experts in the power companies are divided. The data and expertise exchanges between the on-site maintenance teams and data center are delayed due to the lack of effective communication. This paper introduces an on-site smart operation maintenance system for substation equipment based on mobile network. It is able to establish real-time communication and data exchange channels between the maintenance teams and data center. It consists of an operation and maintenance system platform located on the data center side and smart operation and maintenance boxes with mobile APP which are carried to the field side by the maintenance teams. As the kernel of the system, the smart boxes are bridges between the data center and operation sites. On one hand, it is able to formally upload data to the data center in real-time. One the other hand, the operation and maintenance personnel are able to call for help from the resource on the data center anytime. Using the system proposed in the paper, both efficiency of the operation and maintenance and the normalization of the data can be improved.

New Framework

A world-class maintenance system (WMS) refers to the best practices in maintenance that are followed and adopted by various organizations to transform themselves to be a 'world-class manufacturer'. One of the important factors in developing a 'world-class' maintenance system within an organization is the adoption of a sound framework that provides the necessary conceptual and theoretical details of best practices to be followed, to reach the world-class status. Several authors, consultants and large organizations have proposed different frameworks representing the best practices in maintenance, which seem to have been developed and derived primarily from the context and experience of such large organizations and consultants respectively. A comparative study revealed that most of the frameworks are unique and proposes several unique best practices in maintenance. Hence, in this paper, an attempt has been made to identify such best practices from the existing frameworks and integrate these practices to develop and propose a new framework for world-class maintenance systems.
