measuring the performance of a software Maintenance Department
Conference on Software Maintenance and Reengineering, 1997Co-Authors: H M SneedAbstract:All studies indicate that over half of an average data processing user staff is committed to maintaining existing applications. However, as opposed to software development where productivity is measured in terms of lines of code, function-points, data-points or object-points per person month and quality is measured in terms of deficiencies and defect rates per test period, there are no established metrics for measuring the productivity and quality of software Maintenance. This means that over half of an organization's software budget cannot be accounted for. The costs occur without being able to measure the benefits obtained. A set of metrics is proposed for helping to remedy this situation by measuring the productivity and quality of the Maintenance service.

The Predictive Maintenance Concept in the Maintenance Department of the “Industry 4.0” Production Enterprise
Foundations of Management, 2018Co-Authors: Duc Tran Anh, Karol Dąbrowski, Katarzyna SkrzypekAbstract:Modern technical environments require a high degree of reliability both in machinery and in equipment. Technological progress has, on the one hand, increased this efficiency but on the other hand, it has changed the way in which this equipment and these machines have traditionally been maintained. The authors have set the following assumptions. In order to survive in the market and develop, modern production enterprises realize the assumptions of Industry 4.0, wherein the optimization of Maintenance processes is important because of the financial situation. This includes the profits made by the production company and differs from traditional Maintenance, by shifting towards new trends such as predictive Maintenance; as such, it is crucial for the development of the company. The article is devoted to the most modern predictive Maintenance strategy, in the Maintenance Department of a manufacturing company. The publication describes the meaning of the method, its potential and the theory of action.

safety performance evaluation for civil aviation Maintenance Department
International Conference on Human-Computer Interaction, 2018Co-Authors: Yijie Sun, Yuan Zhang, Rong Zhao, Yanqiu ChenAbstract:The MMEM model and the core risk analysis method are applied to construct the safety performance index system of the civil aviation Maintenance Department, and four categories of the safety performance indicators are set up, including Maintenance error, aircraft condition, safety foundation and safety management. In order to take into account the different effects of subjective and objective weights, the comprehensive evaluation model based on the subjective and objective combination weight method for the safety performance of the airline Maintenance Department is established. The analytic hierarchy process and entropy method are used to calculate the subjective weight and objective weight of the index respectively, and the optimization theory is used to calculate the combination weight of the index. The data from 2011 to 2016 in a Maintenance Department of an airline is used as an example of application, and the results of the evaluation are analyzed. The results show that the proposed safety performance evaluation model can quantitatively reflect the safety state of the Maintenance Department and the evaluation results are reasonable.

Optimising agile development practices for the Maintenance operation: nine heuristics
Empirical Software Engineering, 2015Co-Authors: Lise Tordrup Heeager, Jeremy RoseAbstract:Agile methods are widely used and successful in many development situations and beginning to attract attention amongst the software Maintenance community – both researchers and practitioners. However, it should not be assumed that implementing a well-known agile method for a Maintenance Department is therefore a trivial endeavour - the Maintenance operation differs in some, important respects from development work. Classical accounts of software Maintenance emphasise more traditional software engineering processes, whereas recent research accounts of agile Maintenance efforts uncritically focus on benefits. In an action research project at Aveva in Denmark we assisted with the optimisation of SCRUM, tailoring the standard process to the immediate needs of the developers. We draw on both theoretical and empirical learning to formulate seven heuristics for Maintenance practitioners wishing to go agile.

Going Green in the Maintenance Department
Mass Transit, 2008Co-Authors: Leah HarnackAbstract:This article describes how transit agencies are making their Maintenance facilities more sustainable. Creative construction materials, the use of renewable energy, conservation of certain resources, reducing pollutants and defining goals in ways that can be measured are discussed. The Santa Clarita Transit Maintenance Facility includes a 25,000-square-foot Maintenance building made with straw-bale construction. The Los Angeles county Metropolitan Transportation Authority saves $200,000 annually in electricity costs by covering the roof of the Carson bus division’s Maintenance facility and six carport structures with photovoltaic solar panels. A New York City Transit’s Maintenance shop and car washer in Queens harvests rainwater to wash the cars. Other examples are provided, as well as a description of the Leadership in Energy and Environmental Design (LEED) rating system.

Cutting Costs with Software in the Maintenance Department
Mass Transit, 2007Co-Authors: Leah HarnackAbstract:This article outlines the manner in which an operation can cut costs through the use of software programs that track labor, parts, warranty tracking, and Maintenance scheduling. The central principle of this form of operations economics is that preventative Maintenance is more efficient and cost-effective than reactive Maintenance. Often agencies will be able to cut back their fleet if good software monitoring is in place, as each vehicle will be able to provide a heavier workload. Diagnostic time for the vehicles themselves can also be decreased by using automatic vehicle monitoring (AVM), which keeps check on the engine, transmission, event data recorders, and camera systems. In choosing the proper technology for a given operation, the article urges that the desired end product should be kept in mind at all times. Potential intelligent transportation systems (ITS) approaches are also discussed in passing. The article closes by outlining some future expectations.
