Despite ambitious efforts in various fields of research over multiple decades, the goal of making academic research relevant to the practitioner remains elusive: theoretical and academic research interests do not seem to coincide with the interests of managerial practice. This challenge is more fundamental than knowledge transfer, it is one of diverging(More)
To improve demand chain performance, is it better for parties in a supply chain to focus first on lead time reduction, or instead concentrate on improving the transfer of demand information upstream in the chain? Even though the theory of supply and demand chain management suggests that lead time reduction is an antecedent to the use of market mediation(More)
This study looks at how increased memory utilisation affects throughput and energy consumption in scientific computing, especially in high-energy physics. Our aim is to minimise energy consumed by a set of jobs without increasing the processing time. The earlier tests indicated that, especially in data analysis, throughput can increase over 100% and energy(More)
We document a three year long process improvement project in a globally distributed engineering company developing, delivering and supporting a complex software system with tailored hardware components and unique end-customer installations. By applying the domain knowledge from manufacturing and production operations management on lead time reduction and(More)
Conceptual modelling is needed to form a description of the domain of application at hand. In order to express the result of conceptual modelling, we need a modelling language. First order predicate logic (FOPL) or its variants (like Horn-clauses and Description Logics) and extensions (second order logics) can form a backbone of such a language, but some(More)
In improving demand chain performance, is it better for parties in the chain to first focus on lead time reduction, or first focus on improved information flow? Whereas supply and demand chain management theory suggests that lead time reduction is a necessary antecedent to successful information flow improvement, demand chain parties are often observed in(More)
