Reverse Logistics Networks (RLNs) have grown in importance after return policies became compulsory. Lately, questions have been raised whether they are as helpful to the environment as possible. Efforts have been conducted to optimize RLNs in terms of their eco-efficiency, minimizing costs and emissions; still, results are not advancing with the necessary speed. Alternatively, the ecoeffectiven...
This paper formalizes three kinds of safety to be satisfied by networked appliances and services in the emerging home network system (HNS). The local safety is defined by safety instructions of individual networked appliances. The global safety is specified as required properties of HNS services, which use multiple appliances simultaneously. The environment safety is derived from residential ru...
We present an interactive modeling system for flower composition that supports seamless transformation from an initial sketch to a detailed three-dimensional (3D) model. To begin, the user quickly sketches the overall appearance of the desired model as a collection of two-dimensional (2D) strokes on hierarchical billboards. Then the user iteratively replaces the coarse sketch with a detailed 3D...
The paper demonstrates that a wide variety of event-based modeling approaches are based on special cases of the same general event concept, and that the general event concept can be used to unify the otherwise unrelated fields of information modeling and process modeling. A set of event-based modeling approaches are analyzed and the results are used to formulate a general event concept that can...
If we are manage complexity, we must create a model of the universe. The goal of model is to create a meaningful abstraction of the real world. Such an abstraction should be simpler than the real world but should also reflect accurately the real world so that we can use the model to predict the behavior of things in the real world. The object-oriented software design is about building good mode...
In the past years, many OCL tools achieved a transition of OCL from a language meant to constrain UML models to a universal constraint language applied to various modelling and metamodelling languages. However, OCL users still experience a discrepancy between the now highly extensible parsing and evaluation backend of OCL tools and the lack of appropriate frontend tooling like advanced OCL edit...
This paper is presentation of resulting physical models that were used to explore the relationship between design modeling in CAD and digital fabrication with plywood sheets. We explored a process in making tabletop models with digital fabrication machines and thin plywood sheets. Each was built from combination of predetermined wood joining techniques and structures. These models are believed ...
construction industry consists of several phases in which a variety of stakeholders are involved. as construction projects are becoming larger, more complex and more diverse, the design phase has been more important factor for the success of projects than ever before. however, it is considered that most of design work occurred in actual design process is intangible. such recognition makes the d...
Today, modeling is critical for cognition and analysis of designers in industry field to meet their needs and design based on design requirements and available facilities to accelerate production and development of components of industrial engines. In this study, one structure has been proposed, designed, and analyzed based on turboshaft marine engine type to test this kind of engine in order t...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
