Abstract

Purpose

The purpose of this paper is to investigate the autoclave-pump pressured water distribution system. Pressured water is used in many manufacturing processes, as a raw material or as a service fluid for different applications.

Design/methodology/approach

The performances and the total installation costs of such systems are strongly related to its design and to its decision variables definition. The authors first identify the independent variables (i.e. the decision variables) and the dependent variables of the system and, second, propose a techno-economic mathematical method able to determine its minimum installation cost with an integrated approach.

Findings

The trade-off between the autoclave installation costs versus the pump installation costs is demonstrated. A sensitive analysis of the cost of the system as function of its decision variables has been performed to propose a practical graphical analysis tools to proper design the integrated pump-autoclave pressured water distribution system.

Originality/value

Many previous researches focus only on the pump system optimization or in the tank system optimization without an integrated approach. The wide utilization in industry of the autoclave-pump pressured water distribution system together with the lack of similar contributions in this area enforces the value of this research.

Abstract

Purpose

Wastewater treatment plants (WWTPs) are evolving toward sustainability. The purpose of this paper is to discuss how innovation can develop these mission-based service industries to value-added manufacturing enterprises. Here, innovation is embedded in altering the understanding of stakeholders toward the objectives and managerial systems of these infrastructures.

Design/methodology/approach

This study uses multidisciplinary principles in management, economics and engineering to assess the integration of innovation and quality management with different perspectives. It initially compares the conventional and innovative approach for operating WWTPs. Subsequently, it emphasizes the contribution of the tailor-made managerial system of wastewater treatment enterprises through prospective markets, customers’ preferences, probable competitions and shared values.

Findings

The tailor-made managerial system for wastewater treatment can add economic values by manufacturing multiple demand products for local markets. Water, green energy, organic fertilizers and raw materials are the main products that can be simultaneously recovered according to the customers’ demand. The Kano model also verifies that the new managerial system has this potential to turn the conventional must-be treatment systems into delightful enterprises. It can provide different stakeholders with shared social and environmental values. Accordingly, locals and customers can be engaged in monitoring the quality of products to consider their feedback for decision making and upgrading. This indirectly defines shared values among operators and society to reinforce localization and ecosystem protection. Additionally, this research reveals that the market of the aforementioned strategic products is promising as a blue ocean for set sail due to the lack of competitors.

Originality/value

This study introduces wastewater treatment as a promising enterprise for integrating innovation and quality management.

Abstract

Water systems in civil aircraft, stimulated by passenger comfort needs, have grown to be a comprehensive and important part of aircraft engineering. In this article, following a review of the system types, the design features arc discussed in detail and emphasis has been placed on the functional and hygiene requirements, and on the need for simplicity and weight conservation. Attempts have been made to augment air‐borne water supplies by reclamation means, but these have not been too successful. Investigations should therefore continue into the ways and means of improving the utilization of existing ‘fixed’ capacity systems. Installation safety aspects are also discussed.

Abstract

Purpose

Lean manufacturing is one of the leading paradigms for fast and proficient manufacturing but its proper implementation is a foremost task due to certain barriers affecting lean and can be handled when utilized with RFID technology. With this aspect in view, the purpose of this paper is to enlighten and present a thorough literature study that can show how RFID-based lean manufacturing is helpful for handling barriers affecting lean manufacturing in light of previous literature available.

Design/methodology/approach

In order to achieve this purpose a systematic literature review is conducted to justify the impacts of RFID technology for handling barriers. The aim of this systematic literature review is to initially find the barriers affecting lean implementation and then to explain the properties of RFID-based lean manufacturing which are highly feasible to handle detected barriers.

Findings

An interrelation is generated in this study which provides a clear indication that the properties of RFID carry significant effects to handle detected barriers in the operational, managerial and financial regime of manufacturing companies. The detected barriers that affect lean implementation are company’s cultures, top management commitment, poor employee administration, lack of finances, unbalanced inventory control, unstable customer handling and longer lead times. The properties of RFID-based lean manufacturing like operational visibility, inventory control, production control, minimized lead times and the real-time data information (to facilitate top management and employees on shop floor) are extremely helpful to control these barriers.

Originality/value

The originality of this study is the provision of clarity provided to both academicians and practitioners by citing and utilizing previous research studies which undoubtedly indicates positive impacts of RFID on lean implementation.

Abstract

Cleaning metals used in helicopter manufacture. As a result of a search for a generalised method of cleaning metals used in helicopter construction, and which would be safe in all areas, Westland Helicopters Ltd, Yeovil, now uses two Oakite cleaners throughout the factory. Both are alkaline and are supplied in bulk by Oakite Ltd. Both have had to meet stringent AQD approved internal specifications for metal treatment which include requirements that chemical reaction with, or attack by, the cleaner on the metal surface and that tolerances of 0.0001 inch (0.025mm) must be maintained, especially on magnesium.
