Process Modeling, Simulation and Optimization: From Single Solutions to a Multitude of Solutions to Support Decision Making

Purpose The main purpose of this paper is to develop a study of the determination of the most appropriate execution steps, necessary for the construction of modelling, simulation and optimization for the specific area of slaughter line balancing. And through the developed model to demonstrate the application of simulation to increase productivity in a large-size swine slaughterhouse, focusing on operator stations balancing. The built model may be applied to support the management of the plant, allowing to evaluate and decide the optimized scenario that meets current needs considering operational cost, production demand and productivity. Design/methodology/approach For the research development, the selected software supports the characteristics of the evaluated process, in this case, a discreet simulation with stochastics variables. The studied plant was modelled door by door, from the swine reception until the packaging area. The research methodology was based on lean manufacturing (LM) principles, particularly in workstations balancing, by optimizing the idle time of the operators, comparing with the cycle time of each task, in the evaluated workstations. Findings The achieved result with the modelling and simulation was the increase of 11.89% in plant productivity through manpower optimization. The study indicates that the simulation applied with LM concepts as operative stations balancing and value stream map can be a very useful tool to support decision-making for productivity improvement. Originality/value This study approaches how modelling and simulation can support decision-making to implement improvements associated to workforce balancing optimization, especially in the studied area (agribusiness, animal slaughter). The studied process presents great variability associated with the processing time of each phase, making the analysis and modelling more complex. The number of workstations involved, with more than 800 employees, is an important point in the research, considering that cases with higher values than the case presented were not identified in literature.

Made In

The reception of journalists at the Waspada Daily Medan always went through several rigorous selections before being determined to be accepted as journalists at the Waspada Medan Daily. There are several criteria that must be possessed by each participant as a condition for becoming a journalist in the Daily Alert Medan. To get the best participants, the Waspada Medan Daily needed a decision support system. Decision Support Systems (SPK) are part of computer-based information systems (including knowledge-based systems (knowledge management)) that are used to support decision making within an organization or company. Decision support systems provide a semitructured decision, where no one knows exactly how the decision should be made. In this study the authors applied the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) as the method to be applied in the decision support system application. The VIKOR method is part of the Multi-Attibut Decision Making (MADM) Concept, which requires normalization in its calculations. The expected results in this study can obtain maximum decisions.Keywords: Journalist Acceptance, Decision Support System, VIKOR

Support Decision Making

Within a clinical sports medical setting the discussion about doping is insufficient. In elite-sports use of pharmaceutical agents is daily business in order to maintain the expected top-level performance. Unfortunately, a similar development could be observed in the general population of leisure athletes where medical supervision is absent. As a sports physician you are facing imminent ethical questions when standing in between. Therefore, we propose the application of a standardised risk score as a tool to promote doping-prevention and launch the debate within athlete-physician-relationship. In the longterm such kind of risk stratification systems may support decision-making with regard to «protective» exclusion of sporting competition.
