Name of Author: Frank Grimm Thesis Title: Enabling collaborative modelling for a multi-site modeldriven software development approach for electronic control units An important aspect of support for distributed work is to enable users at different sites to work collaboratively, across different sites, even different countries but where they may be working on the same artefacts. Where the case is...

An efficient method for size and layout optimization of the truss structures is presented in this paper. In order to this, an efficient method by combining an improved discrete particle swarm optimization (IDPSO) and method of moving asymptotes (MMA) is proposed. In the hybrid of IDPSO and MMA, the nodal coordinates defining the layout of the structure are optimized with MMA, and afterwards the...

The sewer layout in flat areas significantly influences the construction and operational costs as well as reliability of the network performance. To find an optimum design of sewer networks for flat areas, this study presents a multi-objective optimization problem with the objective functions of 1- the cost and 2- the reliability. The reliability criterion is defined as the effect of a clogging...

Using SLP method obtains the comprehensive correlation through analysis of logistics relationship and non-logistics between various operating units warehouse. According to current situation related warehouse problem, designers can formulate a feasible plan. However, owing is insufficient in solving problem facility layout, that is, it easy be influenced by subjective factors designer, especiall...

  A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...

conclusions in our center, prolonged length of stay in the icu correlated positively with euro score. the overall predictive performance of euro score is acceptable and provides both surgeons and intensivists with a good estimate of patient risk in terms of icu stay. background risk stratification models allow preoperative assessment of individual patients cardiac surgical risk and enable analy...

the integration of an approximate model and a clonal selection algorithm (csa) is considered to one of the most effective ways to solve complex optimization design problems in engineering. in this study, first, a process for developing an approximate model and the principles of clonal selection algorithms were presented. then, a variotherm temperature injection mold used to produce a large liqu...

Layout design problem is one of the useful field of study used to increase the efficiency of sources in organizations. In order to achieve an appropriate layout design, it is necessary to define and solve the related nonlinear programming problems. Therefore, using computer in solving the related problems is important in the view of the researchers of this area of study. However, the designs pr...
