Layout Planning Technology of Cellular Manufacturing System Based on Process Interconnection Analysis

With sustaining change of production mode,layout planning is no longer a thing built once for all.Cellular layout(CL) is becoming a hotspot in the research field of manufacturing system layout.Traditional researches on layout planning are mainly concentrating on aspects of layout arithmetic,style and evaluation,etc.Relatively seldom efforts are paid to CL and its specific problems as cell formation(CF),equipment sharing and CL analysis.Through problem analyzing of layout in cellular manufacturing system(CMS),research approach of cell formation,interactive layout and layout analysis threaded with process interconnection relationship(PIR) is proposed.Typical key technologies in CL like CF technology based on similarity analysis of part processes,interactive visual layout technology,layout evaluation technology founded on PIR analysis and algorithm of cell equipment sharing are put forward.Against the background of one enterprise which encounters problems of low utility of key equipments and disperse material logistic,an example of four-cell layout is given.The CL adjustment and analysis results show that equipment with high level of sharing degree should be disposed around the boundary of its main cell,and be near to other sharing cells as possible; process route should be centralized by all means,so equipment adjustment is to be implemented along direction that route intersection can be decreased; giving consideration to the existence of discrete cell,logistic route and its density should be centralized to cells formed.The proposed research can help improve equipment utility and material logistic efficiency of CL,and can be popularized to other application availably.

The virtual environment construction issues are discussed. An example of the immersive VR application of facility layout is examined.

Analysis of problems in urban green space system planning in China

This paper discusses the major problems in urban green space system （UGSS） planning at both general and special planning levels in China. At general planning level, the problems of the UGSS are mainly from the ignorance in the characteristics of urban nature spaces and the limitation factors of the urban planning system. Great importance is attached to the green spaces in the built area of city, but the green spaces in surrounding areas of the city is unnoticed. Furthermore, because the area of UGSS planning is strictly limited by the administrative zoning, the green space system loses its integrity and rationality in spatial patterns. The schedules of urban development planning mismatched the paces and progresses of the ecological restoration cycles. At special plan level, the problem of the UGSS in China is that the green spaces quantity was over emphasized but the rationality of their layouts is neglected.. Meanwhile, the requirement of the spatial structures and the green spaces layouts to balance between the urban development and the natural ecological environments is often ignored. With regard to the layouts in the UGSS planning practices, the existing problems are the compromising to the existing land-uses, the ＇filling in＇ approach to plan green spaces and an over-emphasis on the layout patterns.

Facilities Planning for a Creative Company

Facilities planning tools have been used by project managers for planning industry spaces for decades now, but applications in creative organizations are still sparse. This happens mainly because of a gap that exists between engineering and psychology fields, with the first developing planning tools for production but with little concern for creativity and the other developing spaces for creativity, but with a lack of tools. Both try to solve the same issue： fostering productivity in the workplace, but they need to be linked first, in order to accomplish it. How to close this gap？ Can a project manager plan the facilities for a creative organizational in the best way possible？ In this paper, a new approach is used for studying the design of physical environments that foster organizational creativity, combining the results of psychological studies on the impact of physical environment on creativity with the facilities planning body of knowledge applied by industrial engineers. In order to test the results, a single case study is developed in a small IT consulting firm. By using the systematic layout planning （SLP） step by step process, it is shown that by acting on the work environment of the company, the developers creative processes can be boosted and facilitated. It is also shown that both industrial engineering and creativity research have much to contribute to each other and future research topics in the field are presented.

Optimal Planning of Charging Station for Phased Electric Vehicle

Construction of electric vehicle charging station is the premise of the popularity of electric vehicles. In this paper, electric vehicle charging facilities planning is divided into two stages: public demonstration stage and commercial operation stage. In public demonstration stage, This Paper applies maximal covering model into charging station location, and then be solved by the branch and bound method. In commercial operation stage, the charging station’s service areas division is studied based on Voronoi diagram. With the concerning technical restrains, an optimal planning method is presented for newly-increased station positioning and service region division. The method using the most greatly air circuit method and local dynamic characteristics of Voronoi diagram guarantees the reasonable distribution of stations. Then charging station model of optimal load allocation is established by using M/M/c model. In the end, the correctness and validity of the model is verified through simulation of charging station planning.

Redesign Facility Layout with a Kaizen Approach in Testing Laboratory at Balai Pengujian&Sertifikat Mutu Barang Makassar

In trading activities,especially exports in the food commodities sector,several documents must be made and completed by exporters,such as Certificate of Quality,Test-Certificate,and Chemical Analysis.Balai Pengujian&Sertifikasi Mutu Barang Makassar is a government agency operating in South Celebes that tests the quality of various agricultural and plantation commodities.From year to year,demand for testing services has increased along with the number of exports.So,testing activities have changed in terms of facility layout requirements resulting in overwhelmed in carrying out the testing process.Test rooms are not connected based on the current testing flow causing the tester’s ineffective work patterns.This study aims to redesign the layout of the facilities in the testing laboratory with the Kaizen approach to support the smooth testing process.The results of this study indicate that the proposed floor area uses a 150% allowance so the calculation requires a floor area of 42.52 m^(2).After that,an analysis of the proximity of the facilities is carried out by making ARC(Activity Relationship Chart)and ARD(Activity Relationship Diagram).Based on ARD,a template is made for the layout of testing laboratory facilities.This study applies Kaizen theory with the 5S concept to obtain a neater design,namely Seiri and Seiton in the refreshment laboratory and weighing room,Seiso on testing equipment in all testing laboratory rooms,Seiketsu and Shitsuke applied to all rooms in the testing laboratory.
