Abstract
Given the enormous scope of the decontamination and decommissioning (D&D) work that government and industry face, there is a tremendous opportunity to save money and avoid further insults to the environment and to human health by applying the principles of life cycle analysis (LCA). An LCA approach is presented that is especially valuable in D&D decision making because it provides a systematic, comprehensive, defensible decision‐aiding process to find solutions that reduce costs and risks of D&D projects. Our approach to LCA differs from other approaches by taking into consideration all the factors important to owners and stakeholders – life cycle cost, health and safety, the environment, programmatic impacts, and other factors. Stakeholder participation is also a key part of the process. The result is robust, durable solutions for even the most complex D&D project. A specific demonstration of this approach to aid D&D at two US Department of Energy sites is presented.

Abstract
Purpose
The purpose of this paper is to investigate maintenance and production problems in the cement industry in Libya, with particular emphasis on future implementation of total productive maintenance (TPM).
Design/methodology/approach
The paper presents the use of case study approach of production data and history, field visits, a survey methodology using a detailed questionnaire with employees and interviews with top and middle managers in four cement factories.
Findings
It has been found that the four factories under investigation have low productivity and production levels when compared with the design values. There is no clear TPM strategy and also it has been found that the lack of training and personal development is the main cause of this problem. In addition, employees are found not to be motivated as a result of the lack of a management strategy and reward structure.
Research limitations/implications
Based on the findings, a new framework for TPM has been developed. This TPM strategy could be implemented in other Libyan factories as a result of the potential similarities in the cultural and environmental aspects.
Practical implications
The current challenges have been identified and comparative analysis is developed into a model for the implementation of TPM.
Originality/value
The paper highlights limitations in some of the cement factories in Libya in relation to TPM and production strategies. The importance of adopting a realistic strategy and framework by managers is discussed. This work is developed as collaboration between academia and one of the Libyan cement companies to solve productivity problems and develop a strategic framework of TPM for improving Libyan industry.

Abstract
Purpose
The purpose of this paper is to present a study of reliability-centred maintenance (RCM), which is conducted on the key sub-assets of a newly constructed road junction infrastructure in Nigeria.
Design/methodology/approach
The classical RCM methodology, a type of RCM, which has a top down, zero-based approach for maintenance analysis, is implemented in this study.
Findings
The implementation of the classical RCM is successful in its application of various PM policies assigned to the assets and it shows that its application in the highway industry could reduce excessive maintenance backlog and frequent reactive maintenance by effective optimisation of its preventive maintenance (PM) intervals.
Practical implications
Road junctions are originators of more than 70 per cent of road traffic congestion and account for high accident rate. The traditional methods of reliability assurance used in the highway industry such as reactive maintenance and routine maintenance are often inadequate to meet the round the clock usage demands of these assets, thus the consideration for the application of a systematic RCM process for maintaining the system function by selecting and applying effective PM tasks.
Originality/value
It uses an approach that critically develops and analyses thoroughly preventive and continuous maintenance strategy in a new circumstance with environment of uncertainty and limited operating data. The case-based reasoning cycle has been applied in the RCM approach with real-time data obtained from a UK-based network maintenance management system for highway infrastructures.

Abstract
Purpose
The purpose of this paper is to present issues and challenges of scheduled maintenance task development within the maintenance review board (MRB) process, and to find potential areas of improvement in the application of the MSG‐3 methodology for aircraft systems.
Design/methodology/approach
The issues and challenges as well as potential areas of improvement have been identified through a constructive review that consists of two parts. The first part is a benchmarking between the Maintenance Steering Group (MSG‐3) methodology and other established and documented versions of reliability‐centred maintenance (RCM). This benchmarking focuses on the MSG‐3 methodology and compares it with some RCM standards to identify differences and thereby find ways to facilitate the application of MSG‐3. The second part includes a discussion about methodologies and tools that can support different steps of the MSG‐3 methodology within the framework of the MRB process.
Findings
The MSG‐3 methodology is closely related to the RCM methodology, in which the anticipated consequences of failure are considered for risk evaluation. However, MSG‐3 considers neither environmental effects of failures nor operational consequences of hidden failures. Furthermore, in MSG‐3, the operational check (failure‐finding inspection) is given priority before all other tasks, whereas in RCM it is considered as a default action, where there is no other applicable and effective option. While RCM allows cost‐effectiveness analysis for all failures that have no safety consequences, MSG‐3 just allows it for failures with economic consequences. A maintenance program that is established through the MRB process fulfils the requirements of continuous airworthiness, but there is no foundation to claim that it is the optimal or the most effective program from an operator's point‐of‐view. The major challenge when striving to achieve a more effective maintenance program within the MRB process is to acquire supporting methodologies and tools for adequate risk analysis, for optimal interval assignments, and for selection of the most effective maintenance task.
Originality/value
The paper presents a critical review of existing aircraft scheduled maintenance program development methodologies, and demonstrates the differences between MSG‐3 and other RCM methodologies.

Abstract
Purpose
The aim of this research is to develop a model for environmental management from which quantifiable indication of overall environmental performance for an organisation may be derived.
Design/methodology/approach
The links between environmental performance and financial performance are considered. Several research methods are described which consider pollution performance. However, it is clear that no single method wholly reflects quantitative pollution management (QPM). The initial model for QPM is derived, and the weightings that should be allocated for the individual and combined categories in achieving the indicator of pollution performance are established.
Findings
The paper establishes a methodology for the derivation of a QPM indicator that provides a numeric variable, by using numerical values that have been obtained from a set of linguistic values evaluated against determinations of prescribed events. The robust nature of the developed QPM indicator is provided by means of a prescribed methodology where the outcome indicator is constructed from the results of the audit and the inter‐relationship of the individual components. This inter‐relationship of numeric and linguistic variables encourages the use of modified set theory in which an individual could have a degree of membership ranged over a continuum of values.
Practical implications
The development of a quantifiable pollution indicator enables customers/consumers to make a purchase decision that takes into account environmental concerns. These unique QPM indicators will assist in promoting a sustainable management strategy with preventative approaches to pollution. Under these circumstances, a QPM indicator would allow industrial and regulatory strategies to be implemented beyond the traditional boundaries of pollution control and waste management. It would give a broader perspective on performance, and encourage application of preventive technologies to reduce pollutant and waste loads, while also promoting environment‐friendly products and services through openly available quantitative indicators. The derived indicator will be limited to the state of a particular process at a given point in time, and as such will need recalculation over given time intervals. This methodology enables the organisation to demonstrate improvement, if applicable. Monitoring tools should in any case be an aid to strategy formulation, not a determinant of it.
Originality/value
This study will assist in allowing environmental performance to become a strategic factor in business planning. Direct comparisons may be made between the operational characteristics of organisations, and how those organisations impact on the environment via pollution, providing direct business benefits to organisations that manage their business and protect the environment.

Abstract
A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.
