Airline pilot perceptions and implementation of fuel saving actions

With the introduction of the carbon emission cost system initiated by the Carbon Offsetting and Reduction Scheme for International Aviation(CORSIA), the improvement of fuel efficiency in flight operations will have higher impact on airline profitability than before. In-flight fuel consumption is somewhat influenced by pilots’ technical...

User-centric analytic approach to evaluate the performance of sports facilities: A study of swimming pools

While the performance of sports facilities such as swimming pools is crucial to the health, safety and enjoyment of pool users, little research has been conducted to explore how to analytically evaluate the holistic performance of such facilities from the users' perspective. Even an evaluation framework portraying the key performance attributes...

A hybrid Delphi-AHP multi-criteria analysis of Moving Block and Virtual Coupling railway signalling

The railway industry needs to investigate overall impacts of next generation signalling systems such as Moving Block (MB) and Virtual Coupling (VC) to identify development strategies to face the forecasted railway demand growth. To this aim an innovative multi-criteria analysis (MCA) framework is introduced to analyse and compare VC and MB in...

Gap theory based post-occupancy evaluation (GTbPOE) of dormitory building performance: A case study and a comparative analysis

Student housing significantly influences the quality and competitiveness of the university education environment. Whereas the traditional post-occupancy evaluations (POEs) of buildings have typically focussed on investigating users' satisfaction, an earlier study developed the gap theory based post-occupancy evaluation (GTbPOE) method, by...

A fuzzy multi-attribute HAZOP technique (FMA-HAZOP): Application to gas wellhead facilities

Hazard and Operability analysis (HAZOP) is a popular technique for hazard identification and risk ranking in hazardous facilities. Conventional HAZOP, however, has some drawbacks: (i) it considers a limited number of risk factors, i.e., only the frequency and the severity of hazards; (ii) it assumes equal weights for the risk factors, thus...

Developing A Priority-Based Decision Making Mod To Evaluate Geometric Configuration Of Urban Interchanges

The present article involves in evaluation and engineering judgment of various geometric configurations for highway interchanges by considering substantial parameters over the discretion process. The geometric, economical and architectural criteria as the fundamental indicators are divided into related sub-indicators and the total combinations...

Analyzing the business model for mobile payment from banks' perspective: An empirical study

The increasing number of smart phones presents a significant opportunity for the development of m-payment services. Despite the predicted success of m-payment, the market remains immature in most countries. This can be explained by the lack of agreement on standards and business models for all stakeholders in m-payment ecosystem. In this paper,...

An analytical approach for requirements specification to enlighten design priorities

This paper focuses on bridging the gap between inception and design stages in an analytic way (by using semantic and mathematical modelling) particularly enlightening design priority by using Requirements Specifications. The Requirements Specifications are context-dependent, i.e. a consequence of producing one-of-a-kind projects (typical of the...
