Low-temperature energy systems are processes that require cooling at temperatures below ambient, which are accomplished using refrigeration cycles. Little research has addressed the operational optimisation of refrigeration cycles considering the performance of existing equipment. This work develops a methodology for operational optimisation of refrigerated processes, taking into account existi...

Previous research has emphasized the importance of employees, managers and human efforts in general in attaining operational and strategic benefits from the use of IT. This paper focuses on how human efforts influence operational and strategic benefits attained from the use of the interorganizational systems (IOSs). A conceptual model is constructed combining transaction-cost economics, resourc...

As outsourcing is becoming mandate for today’s business, there has been a variety of researches taking place. This paper discusses on managing operational risks in an organization where one or more business processes are being outsourced. We first review on changing nature of operational risks not only in outsourced process itself, but also among any other interrelated processes. Then a concept...

Service processes, for example in transportation, telecommunications or the health sector, are the backbone of today's economies. Conceptual models of service processes enable operational analysis that supports, e.g., resource provisioning or delay prediction. In the presence of event logs containing recorded traces of process execution, such operational models can be mined automatically. In th...

The improvement of business processes is a perennial top priority of chief information executives (Gartner Group: Leading in Times of Transition 2010). When seeking to re-design business processes to improve operational efficiency, increase compliance or foster business innovation, managers increasingly turn to Business Process Management (BPM) (Smith and Fingar 2003). The attraction of BPM lie...

An operational model of nondeterministic processes coupled with a novel theory of divergence is presented. The operational model represents internal nondeterminism without using explicit internal transitions. Here the notion of internal state e ectively replaces the familiar notion of internal transition, giving rise to an alternative operational view of processes: the weak process. Roughly, a ...
