The paper presents and describes in detail the specific procedures that are carried out during the repair of the crawler unit on the belt wagon BRs 1200.29/32, whose performance is the basis for high quality and efficient maintenance of these machines on site, as well as in repair shops. These procedures are complex interventions performed as part of the preventive maintenance process. The success of the maintenance process is presented as a workflow with as few failures and downtime as possible, also as a process without accidents, and in case of their occurrence, the possibility of the fastest elimination, all of which result in the satisfaction of both users and maintainers.

This is the introduction to the second edition of ‘Practical Psychiatric Epidemiology’ published by Oxford University Press. In this introduction the Editors reflect on developments since the first edition. Themes touched upon include the ongoing need for high quality descriptive data, the contribution of wearable devices and technologies to generating data for psychiatric epidemiological studies, developments relating to the availability of large-scale data resources or so-called ‘big data’ in psychiatric epidemiology, ongoing issues relating to accurate measurement in psychiatric epidemiology and the contribution of complex interventions to effective healthcare service delivery, and in particular, the way in which these are effectively implemented. The chapter concludes with a reflection on the continued importance of psychiatric epidemiology to the field of mental health.

Computerized Prescriber Order Entry

51 Background: Use of systemic treatment computerized prescriber order entry (ST CPOE) and pre-printed orders (PPO) are proven error reduction measures. Such systems are not failsafe, as regimen development depends on cognitive input at critical points and is susceptible to human error. No known guidance currently exists in oncology to ensure regimens are of high quality and built as intended. The purpose of this initiative was to improve the quality of oncology regimens in Ontario. Methods: A review of 35 centres, representing 75 treatment centres in a hub-and-spoke model, was conducted for all active regimens (PPO and CPOE) to ensure they were built as intended, with respect to drugs and doses. Centres completed an exploratory survey to report any unintentional discrepancies and existing maintenance review processes. The survey collected centre demographics and contained descriptive questions to document details of the regimen review and maintenance processes. Results: The review yielded an 86% response rate (12 regional and 18 community cancer centres). Upwards of 700 regimens were reviewed by a multidisciplinary team at each participating centre. Unintentional discrepancies were reported by 7 of the 30 (23%) centres (range of 2 – 141 per centre); types and examples are presented in the Table. Only 2 of 30 centres (7%) had an established regimen maintenance process. Conclusions: The review identified unintentional discrepancies and, due to the potential for patient harm, corrective action has been taken. There is a need for guidance and adoption of a standardized approach in order to sustain a high-quality regimen build and review process across the province. Consensus-based recommendations for ST CPOE and PPO regimen development and maintenance have been developed. Identified discrepancies have been amended and maintenance review processes are now implemented to improve the quality and safety of systemic treatment delivery. [Table: see text]

System maintenance is necessary to prolong the operational life of a system. There are four types of maintenance policies which are corrective, preventive, scheduled and predictive (conditioning based maintenance). However, this paper focuses on preventive maintenance and corrective maintenance policies. In general, the goal of preventive maintenance is to retain the system at its good operating conditions before the occurrence of any failure while corrective maintenance is done as a result of the system’s operating failure. This paper investigates the effects of maintenance activities for Engine Indication and Flight Instruments subsystems of the avionics system of a general aircraft. The simulation of the maintenance process is done using Monte Carlo and Discrete Event simulation methods for different preventive maintenance interval (PMI).

Multiaxial Loadings

In this paper, the concepts of preventive maintenance are pres¬ented in first part, and second part of the paper present several mathematical models for prediction service life as a base for preventive maintenance forecasting. These models aid in determining the frequency of inspec¬tions that will allow the condition of a piece of equipment to be determined in order to plan an appropriate maintenance action. The problem of determination of the service life is directly related to geometry, multiaxial loadings, materials and appropriate models for prediction of the failure propagation. The more precise modelling of these input parameters the more precise and reliable the results are. Therefore in the paper we will present models and procedures for calculations service life, remain service life and/or service control cycle.

Preventive maintenance (PM) in the production industry is one of the most essential measures to eliminate accidental machinery failures by replacing/repairing worn out machines or parts. The decision of when and where to perform preventive maintenance is non-trivial due to the complex and stochastic nature of the industry where PM is implemented. This article deals with the theoretical and practical implementation of preventive maintenance based on a unique modification of the total productive maintenance (TPM) methodology. The innovative approach of preventive maintenance management was implemented in the real production hall of ITT (Czech Republic) and has been verified. Within preventive maintenance, the new concept brings in an innovative method of managing the maintenance process as a whole, from abstract methodical conception to practical usage. The whole new approach has been verified and implemented on industrial equipment. A challenging task while implementing Industry 4.0 technologies is the issue of how to fully gather and analyse operational data from various items of equipment and users under various conditions, which would result in innovative services of equipment maintenance for clients. The solution to this problem is based on an innovative approach to preventive maintenance of complex equipment and could help many industrial companies to increase production and maintenance efficiency.

Scheduling is needed when several activities must be processed at a certain time. Good scheduling maximizes the effectiveness of the use of every activity, so scheduling is an important part of planning and controlling activities. At PT. Pasifik Satelit Nusantara, there are maintenance activities on the devices used by the preventive maintenance process customers needed so that no additional costs occur, so it needs to be done scheduling that can minimize downtime. For this reason, the schedule must be in accordance with the actual conditions in the company so as to minimize downtime so that the process of customer activity is not hampered by damaged equipment. In this study utilizing a round robin algorithm that can schedule human resources that carry out preventife maintenance activities. The author uses website-based media so that it can easily be used by company superiors to schedule technicians or workers.
