Context. Manufacturing Execution Systems (MES) are information systems that manage manufacturing processes in factories. The execution of MES processes requires non-enterprise integration, which integrates MES applications, services, and automation systems within the factories. Objectives. We aim at developing a modeling approach that can be used to represent and execute MES processes. Having such an approach would help MES vendors to reduce the development cost to reconfigure systems, in order to achieve better business flexibility. Methods. In order to understand the state of the art of manufacturing modeling techniques, we perform a systematic literature review (SLR) in scientific article sources, including IEEE Xplore, ACM Digital Library, Compendex, Inspec, and Springer Link. In consideration of the criteria in modeling and executing MES processes, we evaluate the selected process modeling techniques. Based on the result of evaluation, we propose a three-view-based approach to support process execution. We develop a prototype to prove that an MES process can be executed by following our approach. We also conduct semi-structured interviews in industry to validate whether our proposed approach achieves the objectives. Results. In the SLR, 24 primary studies are selected. Our analysis reveals that existing modeling techniques have limitations to enable process execution. To overcome the limitation, we propose a three-view-based approach, which has an MES process view, an abstract plant view to represent the structure of technical systems, and a mapping view to enable the communication between MES tasks and the technical systems. We develop a prototype as the implementation of our approach, which comprises: a graphical editor for the abstract plant view, a generator of message routes for the mapping view, and a typical MES process to be executed in the context of a warehouse management system. The semi-structured interviews we conducted with three industrial experts show positive feedback to use and generalize our approach in industry, in case comprehensive tools can be established. Conclusions. Compared to the existing modeling techniques, the three-view-based approach is specifically tailored toward process execution. Based on the feedback from industry, we conclude that applying our approach provides the possibility to achieve better reconfigurability and flexibility of MES.

Gamification är en strategi som använder spelmekanismer och spelkomponenter för att skapa motivation och engagemang hos användare av olika typer av system. Denna studie syftar till att undersöka om gamification kan användas för att motivera användare av system för tillverkningsindustrin. Studien har genomförts med en initial litteraturstudie och kvalitativa intervjuer med experter inom gamification samt utveckling av system för tillverkningsindustrin. Intervjufrågor har därefter ställts mot tidigare genomförd forskning, för att identifiera möjliga resultat. Resultatet av denna studie visar att spelmekanismer och spelkomponenter skulle kunna användas i ett system för tillverkningsindustrin, förutsatt att det finns ett tydligt affärsmål, mätbar och användbar data samt identifierade drivkrafter hos organisationens maskinoperatörer. Vidare har ett antal punkter identifierats som kan vara motiverande för en användare av system för tillverkningsindustrin: Möjlighet för operatörerna att följa utvecklingen i sitt expertområde Kartläggning av operatörernas drivkrafter, vilken därefter används för att förbättra operatörernas arbetssituation, med exempelvis mer givande uppgifter Belöningar som utdelas är matchade mot operatörernas preferenser, med syfte att vara mer effektiva som motivationsskapare

Shewanella spp. are model electroactive bacteria (EAB) and well-known for their broad metabolic capabilities and extracellular electron transfer (EET) properties, which allow them to utilize a diverse range of carbon substrates, such as formate, lactate, pyruvate, and amino acids. However, the majority of Shewanella spp. cannot metabolize glucose, a naturally occuring carbon and energy source. Here, we examine the electrode respiring potential of Shewanella chilikensis JC5T- and its coexistence with acetoclastic EAB, Geobacter sulfurreducens in glucose-fed microbial electrolysis cells (MECs) operated at a set anode potential condition of 0 V vs. Ag/AgCl. Chronoamperometry analysis revealed that the maximum current density was 0.04523 mA/cm2 (CE: 14.55%) in S-MEC (only S. chilikensis JC5T) and 0.299 mA/cm2 (CE: 53.85%) in CC-MEC (S. chilikensis JC5T and G. sulfurreducens) which is 6.6-folds higher in current density and 3.7-folds higher in coulombic efficiency than S-MEC. Cyclic voltammetry analysis demonstrates presence of biofilm and redox mediator for EET mechanisms. Metabolic analysis showed that S. chilikensis as a monoculture and co-culture with G. sulfurreducens can metabolize glucose and produce intermediates such as acetate, formate, and lactate. These intermediates are likely used to generate electrical current. Collectively, these results provide novel insights on electrode respiring properties of S. chilikensis and its coexistence with acetoclastic EAB, G. sulfurreducens to enhance the current density and coulombic efficiency from glucose-fed MEC.

På grund av ett stort förändringsarbete på SSAB i Oxelösund pågår delmålet att införa ett nytt produktionssystem Manufacturing Execution System (MES). Framtagandet och införandet av systemet är av yttersta vikt, för att undvika problem och eventuella fallgropar bör förarbetet och kravspecifikationen vara i fokus. Syftet med denna kandidatuppsats i informatik är att identifiera utmaningar och framgångsfaktorer för en lyckad kravspecifikation som kan ligga till grund för det fortsatta arbetet med MES-projektet hos SSAB. Kravspecifikationsarbetet som undersöks i rapporten föranleder fasen med integration och testning av det nya systemet. Integrationen kommer ske under första halvåret 2022 där företaget kommer undersöka hur de framgångsrikt ska kunna koppla samman de olika systemen. Integrationen kommer omfatta kring 25 system i 195 olika integrationer. God respons från fem intervjuer som genomförts med respondenter med olika roller inom organisationen, inte bara i direkt beslutstagande positioner har lett till en god insyn i kravspecifikationsarbetet. Respondenter med olika roller inom projektet belyser olika faktorer av värde och sin personliga syn på dessa. Ett par upptäckter i studien var dels den upplevda vikten av projektgruppens åtaganden utanför själva projektet, dels den upplevda och faktiska vikten av struktur i dokumentation av kraven.   Slutsatserna som dras i studien är:  Ett mer detaljerat förarbete bör göras i förstudiefasen i projektet för att ha större förberedelse inför projektets senare delar.    Planera att omfattande projekt tar längre tid än beräknat för att undgå stress och kompromisser. Bör finnas en kombination mellan engagemang och kompetens inom projektgruppen.
