Abstract
Human reliability in computer programming can be improved by reducing human errors. The traditional approaches for error reduction in industry are not applicable to minimizing errors in computer programming. Proposes a model for error reduction in software prior to its final release. The model consists of two modules, an error detection module, and an error correction module. A computational procedure is outlined for determining the optimal number of detection and correction stages prior to the final release of the software.

Abstract
Purpose
The purpose of this paper is to provide an overview of research and development in the measurement of maintenance performance. It considers the problems of various measuring parameters and comments on the lack of structure in and references for the measurement of maintenance performance. The main focus is to determine how value can be created for organizations by measuring maintenance performance, examining such maintenance strategies as condition‐based maintenance, reliability‐centred maintenance, e‐maintenance, etc. In other words, the objectives are to find frameworks or models that can be used to evaluate different maintenance strategies and determine the value of these frameworks for an organization.
Design/methodology/approach
A state‐of‐the‐art literature review has been carried out to answer the following two research questions. First, what approaches and techniques are used for maintenance performance measurement (MPM) and which MPM techniques are optimal for evaluating maintenance strategies? Second, in general, how can MPM create value for organizations and, more specifically, which system of measurement is best for which maintenance strategy?
Findings
The body of knowledge on maintenance performance is both quantitatively and qualitatively based. Quantitative approaches include economic and technical ratios, value‐based and balanced scorecards, system audits, composite formulations, and statistical and partial maintenance productivity indices. Qualitative approaches include human factors, amongst other aspects. Qualitatively based approaches are adopted because of the inherent limitations of effectively measuring a complex function such as maintenance through quantitative models. Maintenance decision makers often come to the best conclusion using heuristics, backed up by qualitative assessment, supported by quantitative measures. Both maintenance performance perspectives are included in this overview.
Originality/value
A comprehensive review of maintenance performance metrics is offered, aiming to give, in a condensed form, an extensive introduction to MPM and a presentation of the state of the art in this field.

Abstract
Maintenance control plays a key role in achieving the stated objective of effectiveness and efficiency of the maintenance system. In a recent paper, Gits proposed a reference framework that guides in the design and structuring of maintenance control. The framework is conceptual in nature and its use in practice is limited. Poses Gits’ framework as a set of mathematical programming models. Extends some of Gits’ procedure for maintenance control, then outlines the required expansion in the maintenance management information system (MMIS) in order to provide the needed data to execute the models. The models provide operational plans and schedules ready for implementation.

Abstract
Turnaround maintenance (TAM) is an essential activity in process industry. It plays an important role in maintaining consistent productive capacity. It is a major project that requires sound planning, execution and control. In this paper guidelines for a structured approach for managing TAM is outlined and the current practice of TAM in petrochemical industry is assessed. The assessment of the current practice is conducted through a structured questionnaire that covers all the essential phases and activities of TAM. Suggestions for improving the practice of TAM are also provided in the paper. Practical implications. This paper provided a structured approach and guidelines for initiating, planning, executing and terminating TAM. The guidelines are expected to evolve into a manual that can be utilized by process industry for managing TAM.

The purpose of this paper is to create a cost model at the general equipment level for industrial maintenance services.
Abstract
Purpose
The purpose of this paper is to create a cost model at the general equipment level for industrial maintenance services.
Design/methodology/approach
The study is divided into two main sections. In the first phase the idea is to create a framework for a cost model with a literature review. The second, empirical part of the study is based on costing information from interviews and information given by network companies: a pulp mill, a maintenance company and an equipment provider. The maintenance of three different equipment processes is examined in the network through a case study, to get more specific information from real world situations to develop the model.
Findings
The findings concern the cost items that should be considered in the model, the structure of the model, and how the general cost model is constructed. During the research the model has been extended, and new cost categories included.
Practical implications
The cost model can be used in various performance measurement and decision‐making situations, such as maintenance service pricing, contract negotiations, outsourcing decisions, and life cycle cost management.
Originality/value
The cost model differs from traditional cost models. Earlier models have focused on the perspective of either the service provider or the customer, but not on both perspectives at the same time. However, in order to achieve a win‐win situation in a business network, open books practice is expected from each member of the network.

Abstract
The quality of academic programs is drastically affected by the design of the courses within the program. The design and delivery of courses are the most essential elements for building quality in academic programs. The purpose of this paper is to customize the techniques of quality function deployment (QFD) for designing courses and demonstrate its use in the design of a basic statistics course in the Department of Systems Engineering, King Fahd University of Petroleum and Minerals. In this study, organizations from industry are used as external customers. Faculty members and students are utilized as internal customers to identify the course technical requirements. Then QFD process planning matrices are used for developing several alternative course design concepts. Then based on a simple decision criterion the design concept that closely meets customer requirements is identified. The result of the analysis is a balanced basic statistics course.

Abstract
Purpose
Value driven maintenance (VDM) is a fairly new maintenance management methodology based on four maintenance value drivers and the formula of net present value (NPV) to calculate the value of different maintenance strategies. However, the dependability of the engineering assets needs to be assessed in order to make an estimation of the NPV. Therefore, the purpose of this paper is to critically analyse standardised indicators to find the most essential indicators for the four value drivers and for estimation of the NPV. Terminology containing performance drivers and killers are common in the field of asset management, but not many publications can be found for their detailed descriptions. One section in this paper is therefore dedicated to review these terms. A comprehensive description and classification of performance killers and drivers, and of indicators for VDM are presented in this paper.
Design/methodology/approach
Review of literature for technical terminology and review of standards for identification of indicators for maintenance performance measurement and NPV of maintenance.
Findings
Common description of technical terminology, as used by researchers, and identification of the most important indicators for maintenance performance measurement and the NPV of maintenance. Indicators classified under economic, technical, organizational and health, safety and environment (HSE) perspectives from EN 15341 standards are discussed and identified.
Originality/value
Description of emerging terminology in maintenance performance measurement adds to the consistency in communication of researchers and business stakeholders. Also, the identified maintenance performance indicators can facilitate performance measurement of organisations new to the process of measuring and analysing their performance.

Abstract
Purpose – The purpose of this paper is to describe how a risk‐based dependability approach can be used to link maintenance performance measurement and management to overall objectives within an organization. Design/methodology/approach – The applied study approach is a case study at Trafikverket (the Swedish Transport Administration). Qualitative data were collected through interviews, workshops and document studies, while quantitative data was collected through data bases. As a framework for analysis, international standards within the risk and dependability areas were applied. Finally, the conclusions of the study were verified by key informants. Findings – Through the proposed risk‐based dependability approach, critical availability goals are communicated with and involve top management. The approach also contributes to enhanced data and information quality by pinpointing critical data and information for dependability management activities. The proposed availability indicator can be used to monitor the effect of dependability management activities aimed at different indenture levels of the infrastructure and related to the responsibility of different hierarchical levels of the organization, e.g. different maintenance echelons. Practical implications – The proposed approach strengthens the internal control of an organization by supporting the achievement of: objectives that are aligned with and support the mission; operations with an effective and efficient use of resources; reliable operational and financial reporting; compliance with applicable laws and regulations. Originality/value – By integrating risk management in the work with availability goals included in the balanced scorecard, a more holistic and risk‐based dependability management practice is achieved.
