This paper deals with dynamic facility layout problem (DFLP) in a plant which is concerned determining the best position of machines during multi-period planning horizon. The material handling costs and rearrangement (MRC) are used to determine layout. In addition positions machines, details transportation such as type transporters sequence operations have direct effect on (MHC). Therefore, it ...

Distributed systems, due to their inherent complexity and nondeterministic nature, are programmed using high-level abstractions, such as processes, actors, ambients, agents, or services. There is a need to provide tools which allow developers to better understand, test, and debug distributed systems. OverView is a software toolkit which allows online and offline visualization of distributed sys...

This paper proposes the problem of modeling video sequences of dynamic swarms (DS). We define DS as a large layout of stochastically repetitive spatial configurations of dynamic objects (swarm elements) whose motions exhibit local spatiotemporal interdependency and stationarity, i.e., the motions are similar in any small spatiotemporal neighborhood. Examples of DS abound in nature, e.g., herds ...

In order to extract high levels of performance from modern parallel architectures, the effective management of deep memory hierarchies is very important. While architectural advances in caches help in better utilization of the memory hierarchy, compiler-directed locality enhancement techniques are also important. In this paper we propose a locality improvement technique that uses data space (ar...

This paper presents LinkScope, a toolkit for interactive analysis of text using node link graphs, with support for dynamic addition of attributes from tabular data. The interaction technique draws on ideas from 3D modeling, mesh deformation, and static graph drawing to promote discovery of hidden information across a wide variety of graph types and analysis tasks. The key innovation of this wor...

We describe and discuss a novel radial version of a scalable dynamic graph visualization. The radial layout encodes dynamic directed graphs on narrow rings of a circle. The temporal evolution of the graph is mapped to rings that grow outward from the center of the circle. Graph vertices are placed equidistantly at the borderlines of each ring. Graph edges are displayed as curved lines starting ...

Evolutionary algorithms, such as genetic algorithms have been used in various optimization problems. In this paper, we propose to apply algorithm obtain the layout design/redesign order improve patient flow an outpatient clinic. Layout designs are planned considering long-term requirements whereas keeps modifying per short-term demands. Over a period of time, often does not remain efficient. Th...

This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavity injection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage. The complexities and principles of cavity layout design as well as various dependencies in injection mould design are introduced. The knowledge in cavity layout design is ...

To design a group layout of a cellular manufacturing system (CMS) in a dynamic environment, a multi-objective mixed-integer non-linear programming model is developed. The model integrates cell formation, group layout and production planning (PP) as three interrelated decisions involved in the design of a CMS. This paper provides an extensive coverage of important manufacturing features u...
