- Many real-world production systems are complex in nature and it is a real challenge to find an efficient scheduling method that satisfies the production requirements as well as utilizes the resources efficiently. Tools like discrete event simulation (DES) are very useful for modeling these systems and can be used to test and compare different schedules before dispatching the best schedules to the targeted systems. DES alone, however, cannot be used to find the "optimal" schedule. Simulation-based optimization (SO) can be used to search for optimal schedules efficiently without too much user intervention. Observing that long computing time may prohibit the interest in using SO for industrial scheduling, various techniques to speed up the SO process have to be explored. This paper presents a case study that shows the use of a Web-based parallel and distributed SO platform to support the operations scheduling of a machining line in an automotive factory.

E-procurement beyond the buyer cost perspective
- 2010

- Purpose: The objective of this paper is to provide and argue for a comprehensive view of e-procurement that involves both the buyer and suppliers and that goes beyond looking at mere cost reductions on the buyer side. More specifically, the paper describes benefits and barriers of implementing e-procurement solutions for both buyers and suppliers.Design/methodology/approach: This paper reports on a literature review combined with a case study. The case is a public organization in Sweden, which prepares to implement an e-procurement solution. Interviews were also conducted with a selection of suppliers to the case organization.Findings: In e-procurement literature, drivers and barriers are often viewed only from the perspective of a buying organization. Benefits are mainly cost-related for the buying organization, while barriers often include suppliers. It is proposed that benefits and barriers should include both buyers and suppliers. The literature review and the case study findings form the basis for further investigation into this problem area.Research limitations/implications: This study focuses on a public organization in Sweden. Yet, it could have implications for many public or private organizations considering implementing e-procurement systems.Practical implications: This research suggest that organizations to a greater extent should take the supplier´s side into account when implementing e-procurement solutions.Originality/Value: The study highlights a full cycle view on e-procurement taking both buyer and supplier into account.

Communicating continuous improvement in manufacturing companies : Divergencies between current practice and theory
- 2017
-
Konferensbidrag (refereegranskat)abstract
- Succeeding with continuous improvement is important for manufacturing companies to increase the competitive edge. In order to succeed with continuous improvement, literature shows that communication of improvement indicators need to be integrated with communication of control indicators. This paper identifies divergencies between current practice and theory in the communication of CI, which can be a reason for why manufacturing companies fail in their CI implementation. An integration of control indicators and improvement indicators could improve continuous improvement results, increasing business performance.

Communicating performance measures : Supporting continuous improvement in manufacturing companies
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Manufacturing enterprises are a key driver of economic growth (Eurostat, 2016). Implementing continuous improvement (CI) is commonly used to increase competitiveness (Hyland et al., 2007), but despite the well-known theory of CI, many manufacturing companies fail in implementing it (Bhasin, 2012; Nordin et al., 2012; Tiwari et al., 2007).An identified critical success factor in CI implementation is the evaluation of performance, including the performance evaluation system itself, the linkage between targets at different company levels, and continual evaluation of performance (Bakås et al., 2011; Scherrer-Rathje et al., 2009; Ukko et al., 2009). Another critical success factor in CI implementation is the communication of performance measures (Bakås et al., 2011; Ukko et al., 2009).This research explores the communication of performance measures. The aim is to support CI by improving the communication of performance measures, and to this end, this thesis concentrates on identifying the main challenges in the communication of performance measures supporting CI. The research scope is manufacturing companies in general, and manufacturing SMEs in particular. The relevant literature concerning the communication of performance measures in manufacturing companies is identified and summarized. Also, current practice is explored, focusing on how performance measures are communicated in manufacturing companies, and whether and how the communication supports CI. This has been done to identify divergences between current practice and theory. Finally, theory and empirical findings are synthesized to identify some of the main challenges to be addressed in order to succeed in CI.The main task is to support CI efforts in manufacturing SMEs, eliminating the identified divergences in the communication of performance measures by adapting these measures to these manufacturing SMEs. These challenges can be summarized as follows: - using both financial performance measures as well as objective and subjective, non-financial performance measures - aligning performance measures with strategy and targets - integrating all performance measure communication, as related to both daily performance and CI, in the same communication loop. - forming two-way communication channels between managers and operators - aligning oral and written communication channels - exploring how information systems can facilitate the communication of performance measures - using and optimizing the visual communication of performance measures

Learning through practical involvement in the OSS ecosystem : experiences from a Masters assignment
- 2007
-
Ingår i: The Third International Conference on Open Source Systems OSS 2007. - Boston, MA : Springer. - 9780387724850 - 9780387724867 ; , s. 289-294
-
Konferensbidrag (refereegranskat)abstract
- Increased awareness of and interest in Open Source has led to a number of university teaching initiatives, at both national and European level. In this paper we present experiences from a practical assignment designed to give students on an Open Source Masters course an insight into real involvement in Open Source projects. It discusses the motivations for the assignment, and how it was set up and executed. It reports on post facto student feedback, and reflects on a parallel, reduced exercise offered at undergraduate level. We find that the learning experience was both positive and valuable in that it gave real insight into Open Source participation, and also encouraged further participation in Open Source projects by students after the course had completed.

UML model interchange in heterogeneous tool environments : an analysis of adoptions of XMI 2
- 2006
-
Ingår i: ACM/IEEE 9th International Conference on Model Driven Engineering Languages and Systems. - Berlin, Heidelberg : Springer Berlin Heidelberg. - 9783540457725 - 9783540457732 ; , s. 619-630

Konferensbidrag (refereegranskat)abstract
- Heterogeneous tool environments are often a reality and it is therefore increasingly important to be able to interchange model information between tools. This is not only true concerning the natural heterogeneity resulting from distributed development contexts; the need may also arise in a tool chain and for legacy reasons. Without this possibility, there is significantly reduced flexibility, and a danger of tool lock-in. In this study we explore the use of the standardised interchange format XMI for supporting interchange of model information between heterogeneous tools. We report on the current state regarding XMI version 2.0 and greater. We find that there seems to be better support for model interchange using XMI 2.0 than for earlier versions of XMI, and speculate that one contributing factor may be the recent integrations of the Eclipse platform in UML modelling tools.
