Design science research involves creating and evaluating innovative methods and approaches to be used in design practice. We present an approach to be used in the process of designing Management Support Systems (MSS). The nature of managerial work makes the design, development, and implementation of MSS a major challenge. The MSS literature suggests that determining MSS requirements and specificat

With diversified requirements and varying manufacturing environments, the optimal production planning encountered in a steel mill became more flexible and also complicated. The flexibility can provide the operators with auxiliary requirements through an implementable integrated production planning. In this paper, a mixed-integer nonlinear programming (MINLP) model is formulated for the optimal pla

Food retailers might foster consumption of sustainable products by influencing both demand and supply-side characteristics, as they represent the main marketing channel of food products in most of European countries. However, only few European retailers are actively engaged in activities of sourcing and promoting more sustainable products, with current share of sustainable food in the retail assor

An increasing demand on load flexibility in power supply networks is the motivation to look at flexible, and possibly optimal control systems for power plants with carbon capture units. Minimizing the energy demand for carbon dioxide removal under these circumstances reduces the cost disadvantage of carbon capture compared to conventional production. In this work a dynamic model in Modelica of a c

With diversified requirements and varying manufacturing environments, the optimal production planning encountered in a steel mill has become more flexible and also complicated. The flexibility provides the operator with auxiliary options to satisfy customer requirements through an implementable integrated production planning. In this paper, a mixed-integer nonlinear programming (MINLP) model is fo

In this study, a group of Swedish social media users – politically active as well as “unpolitical” users – are interviewed in focus groups as well as individually about their attitudes towards online political participation, providing a deeper, more informed view of how social media participation works. Sweden, with its high levels of voluntary participation and with an avant-garde position in Int

Protein S is a cofactor of activated protein C; together they function as a regulator of blood coagulation. A human liver cDNA library constructed in bacteriophage lambda gt11 was screened with DNA fragments from a full-length bovine cDNA clone encoding protein S. Several cDNA clones were isolated and sequenced. The combined cDNA sequences encoded the mature protein and 15 residues of the leader s
