According to [1], the material handling cost comprises about 20-50% of the total operating cost of the facility layout. Typical research on facility layout concentrate on static layout problems where from-to charts are used to evaluate the layout. These layouts are not flexible enough to accommodate any future changes in production. Research on dynamic facility layout also has used the concept ...

Today, graphs are used for many things. In engineering, graphs are used to design circuits in very large scale integration. In computer science, graphs are used in the representation of the structure of software. They show information such as the flow of data through the program (known as the data flow graph [1]) or the information about the calling sequence of programs (known as the call graph...

A geo-statistics method combined with GIS was applied to study the soil special variation characteristics of a typical basin on the Northwestern Plateau of Hebei Province. It indicates that the rational crop layout is determined by the soil texture. And the crop layout optimization schemes were put forward for different production objectives based on the GIS platform with the soilcrops special ...

A high-mix, make-to-order production system can become inefficient when non-value added operations consume too much time, space or labour. To address these issues, cell re-layout is conducted and a CONWIP system is proposed. The cell re-layout started with data collection on current layout, product mix and routings, then the current layout was modified to develop several alternatives, and final...

PT. Alpha Jaya Manunggal Mandiri is manufacturing company engaged in furniture sector. There are several problems with old layout such high material handling costs, long distances between work stations, and alternating flow. Therefore, relayout lean approach were carried out. Alternative layouts made using SLP method, CORELAP. The initial steps making alternative measuring floor area, productio...

â understanding the flow behaviour in a gas well is crucial for future production strategies, obtaining bottomhole conditions from wellhead production data, analyzing production data and estimating reservoir properties. in this work, the pressure profile and flow regime are studied on four wells of a multi-well, multi-layer gas-condensate reservoir, producing at high rate. the wells are deviate...

BACKGROUND Human factors engineering has allowed a systematic approach to the evaluation of adverse events in a multitude of high-stake industries. This study sought to develop an initial methodology for identifying and classifying flow disruptions in the cardiac operating room (OR). METHODS Two industrial engineers with expertise in human factors workflow disruptions observed 10 cardiac oper...

This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...

A design flow for a family of DC/DC converters with integrated switches and digital controller is realized. This design flow contains simulation and hardware evaluation tools which result in a fast optimization of the converter and a fast realization on silicon. The design flow makes extensive use of tools known from a digital design environment. The design flow covers the whole range from init...
