  1. 1. Production optimization using Discrete Event Simulation : Case study of Volvo Penta engine production line

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Antonio José Ramos Calderón; [2022]
    Nyckelord :DES; optimization; genetic algorithms; knowledge extraction; FACTS; MIMER;

    Sammanfattning : Simulation allows decision-makers in modern industries analyse the outputs of specific systems, and predict future ones based on certain decision variables when in combination with optimization and Lean. This project studies the production line of boat engines in Volvo Penta at Vara (Sweden), carrying out different experiments based on a verified and validated model of the real production system using FACTS Analyzer in order to improve the key performance indicators whilst comparing the optimization performance of four genetic algorithms (NSGA-II, NSGA-III, PSO and DE) and extracting knowledge using data mining.

  2. 2. Computational and accuracy benchmarking of simulation and system-theoretic models for production systems engineering

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Antonio José Ramos Calderón; [2021]
    Nyckelord :DES; benchmarking; lean buffer; optimization; simulation software; performance measure; plant simulation; FACTS; PSE toolbox;

    Sammanfattning : The modern industry has an increasing demand for simulation software able to help workers and decision-makers visualize the outputs of a specific process in a fast, accurate way. In this report, a comparative study between FACTS (Factory Analyses in ConcepTual phase using Simulation), Plant Simulation, and PSE (Production System Engineering) Toolbox is done regarding their capacity to simulate models with increasing complexity, how accurate they are in their outputs with different optimized buffer allocations, and how well they perform on the task of detecting the bottlenecks of a process.

  3. 3. The Impact of Finance Mergers and Acquisitions on Short-Term Performance of Acquiring Companies : An Event Study Focused on the British Isles

    Magister-uppsats, Jönköping University/IHH, Företagsekonomi

    Författare :Juan Jose Ramos Nogales; Kreshnik Elshani; [2020]
    Nyckelord :Event Study; Mergers and Acquisitions; Abnormal Returns; Cumulative Abnormal Returns; Market Model; Finance; British Isles.;

    Sammanfattning : Background: Mergers and acquisitions (M&A’s) are common ways for businesses to expand, compete, and maintain in competitive business environments. A strongly debated question in literature is whether or not these M&A’s provide measurable benefits, as factors such as industry, geographic location, and regulations play key roles in the impacts of the M&A’s.

  4. 4. Identification of Suitable Areas for Offshore Macroalgae Cultivation

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Filipe José Nunes da Silva Ramos; [2016]
    Nyckelord :macroalgae; GIS; MCA; GIS-MCDA; Boolean; WLC; sustainability; suitability;

    Sammanfattning : Research in sustainable macroalgae aquaculture has been gaining hype (e.g. Seafarm) to provide advancements in new significant sources of food, feed, materials and bio-energy. Despite the fact that in Asia the offshore production of macroalgae is established for many decades, in Europe is still in its infancy. LÄS MER

  5. 5. Akta er för dörrarna - en observationsstudie av dörröppningar i en hybridsal

    Magister-uppsats,

    Författare :Jennie Hallberg; José Ramos; [2013-07-02]
    Nyckelord :Dörröppningar; Infektioner; Hybridsal; Ventilation; Hygien; Patientsäkerhet; Operationsjuksköterska;

    Sammanfattning : SAMMANFATTNING Tidigare forskning har visat att det kan finns ett samband mellan dörröppningar och postoperativa sårinfektioner. Trots rekommendationer från Socialstyrelsen och de enskilda sjukhusens PM är det fortfarande ett högt trafikflöde i operationssalarna. LÄS MER
