This paper focuses on the contribution of Air Traffic Management to the Überlingen mid-air collision. Events and Causal Factor models are developed to show the interaction between technical, human factors and managerial issues in the causes of this accident. In particular, we show how problems in safety management contributed to an error inducing context. Our analysis also points to the wider d...

During the last years, supply chain performance measures have been in the spotlight of many authors. A large number of various performance measures have been utilised. In this paper a measure of efficiency is used as an indicator of performance in the vegetable supply chain. The study consists of two stages. The first stage involves Data Envelopment Analysis (DEA) which evaluates technical and ...

Congestion is an important issue that requires the efficiency of decision-making units (DMUs). We first classify conventional congestion into congestion (newly defined) and technical inefficiency, based on prior research and real applications. Modified definitions and mathematical expression of congestion, managerial inefficiency, and technical inefficiency are proposed to better illustrate the...

Large, data-rich organizations have tremendously large collections of digital objects to be “repurposed,” to respond quickly and economically to publishing,marketing, and information needs. Some management typically assume that a content management system, or some other technique such as OWL and RDF,will automatically address the workflow and technical issues associated with this reuse. Four ca...

In this paper, we present a synthesis of our fundamental and theoretical research on human system integration and human in-the-loop system for enhancing human performance especially for technical gestures, in safety critical systems operations such as surgery, astronauts’ extra-vehicular activities and aeronautics. Grounding humans-systems integration engineering and design (modelling and simul...

Smart products not only provide novel functionalities, but also may establish new business models, markets, or distribution channels, strengthen relationships with consumers, and/or add smart remote services. While many technical obstacles of such products have already been overcome, the broad market dissemination of smart products still poses some vital managerial challenges for decision maker...

The contractors sector is considered to be one of the most important sectors in terms of its effects on economic development, stabilization, and urbanization. The main objective of this study was to explore and analyze the obstacles facing the contractors sector in Saudi Arabia from the contractors’ point of view using Spearman’s rank correlation method, where the dimensionality of ordinal data...

We discuss and examine empirically a firm-level equivalent of the ancient problem of ‘tying the King’s hands’, namely how to avoid managerial intervention that is undertaken to reap private benefits but is harmful to overall value creation, that is, ‘managerial opportunism’. The link from managerial intervention to firm-level value-creation is moderated by employee motivation. Thus, interventio...

Information technology (IT) has changed the dynamics of competition in the U.S. economy. Firms are gaining competitive advantage by competing on technology-enabled processes. For the retail industry, technology is breaking down the barriers between different retail channels and is making omnichannel retailing inevitable—an integrated sales experience that melds touch-and-feel information in the...
