Process oriented plant layout Functional Layout : Machinery is placed according to what they do and materials go to them. In fixed product layout, the products generally circulate within the production facilities machines, workers, etc. This type of layout is commonly found in industries that manufacture large size products, such as ships or aircrafts.

Process layout groups facilities with similar functions together resources of the same type. This organization is often reported to be suited when there is a wide variety of product. Product layout is used for systems with high production volumes and a low variety of products.

A group decision making process for facility layout in hospital clinical laboratories.

Facilities are organized according to the sequence of the successive manufacturing operations. In Cellular layout, machines are grouped into cells, to process families of similar parts. These cells also need to be placed on the factory floor. Therefore, one is also generally concerned with so called intra cells machine layout problems. The plant layout will be based in allocating a machine as close as possible to the next one in line, in the correct sequence to manufacture the product.

Plant Layout for a Service: Most of the concepts and techniques explained here can be applied to any plant layout, including services. Service Businesses have a more direct customer focus: Sometimes, the customer is required at the facility for the company to be able to perform the service. Frequently, the layout is focused on the customer satisfaction than on the operation itself. Some of the objectives include comfortability during the performance of the service, as well as making attractive those areas in direct contact with the customer.

Plant layout for an office: The material that flows among departments and workstations is basically information. This can be done through:. Many industries use activity relationship charts ARC and diagrams for layout redesign and layout planning. The use of activity relationship diagram in designing a layout has provided a basic step for layout planning. Another research focuses on the problems occurred during designing flexible plant layouts for manufacturing facilities where product demands are subject to variability. A flexible layout is one that maintains low material handling costs despite fluctuations in the product demand levels.

Facility Layout Project Case Study Facility Planning and Design

Being a semiheuristic search, our algorithm is likely to be more efficient in terms of computer CPU engagement time as it tends to converge on the global optimum faster than the traditional CRAFT. A case study explains an in detailed redesign of an existing production facility. The design of production facility differs from that of manufacturing layout. The analysis of the capacity of the equipment is done, then by using this analysis a group technology is used to make different type of parts in a layout and identification of a material handling solution for a material flow.

A research conducted in an industry explains about the warehouse redesign of a manufacturing plant Layout and also the problems faced during the redesign of the layout.

The present plant layout and the operation process of each section i. Pham and Onder et al[7] have developed a knowledge-based system for optimum workplace design. The system is constructed using a commercially available hybrid development tool. It is interfaced to a database of anthropometrical data and an optimization program.

The optimization program employs a genetic algorithm. This combination of knowledge-base technology, genetic optimization methods, and database technology has proved to be an effective for solving complex ergonomic design problems.

This concept is - the ratio line X2 also inappropriate if changeover times are long. Generally speaking, lots can be produced only once,or they can be produced at regular intervals.

In the given case Outlined ratios in P-Q diagram for individual X-es are thelots are produced more or less at regular intervals.

They are as follows:conventionally designed for higher rates of production. Flexibility of lot production line is reasonable i. Current production equipment layout experience of a manager, even though fuzzy criteria for suchand material flow during processing in a mentioned factory decision making are mentioned by Sekine [8],are depicted in Fig. Theoretical Background for Conducting a P-Q Analysis production equipment in technological pattern due to relations After determining current situation in production process between assortment and amount of manufactured pieces beingnext key for building successful operations is an effective not suitable for implementing one-piece flow principles.

It is up to his knowledge to makefuture needs. It should not tie operations to outdated a right decision. To eliminate uncertainty in decision making atechnology.

It produces superior products and enhances mathematical algorithm Fig. First important step for an parameters. World Academy of Science, Engineering and Technology 49 one-piece flow production by using of P-Q analysis areproposed these rules: Fig. Presented theoretical hypothesis will be applied and testedon concrete example of real manufacturing company.

Furthera PFA analysis method will be applied and it will be aimed onoptimization of material flows in scope of logistic goals. Initial Data for Conducting P-Q Analysis be disintegrated into groups according to the group Initial production values needed for conducting P-Q technology concepts. Multi-product process chart based onanalysis are given Table I.

They serve for drawing of P-Q original process layout is showed in figure 6. Each stage in PFA seeks to eliminate delays in production flows and operational wastes in a progressively smaller area of the factory.

Facility Layout and Design

PFA can be defined as comprehensive method for material flow analysis, part family formation, design of manufacturing cells, and facility layout design that was developed in the early By PFA related groups of parts are identified and rearranged into a new pattern that brings together packs with similar machine sequences.

A mathematical formulation of the production flow analysis optimization problem was developed for instance by Villa and Bandera [11]. By applying the results of PFA also called as cluster analysis , a production equipment layout with optimized lines can be modeled. Basic principle of cluster analysis is shown in Fig. The semi-products are divided was derived from Table II, it was created a model ofinto three assembled groups.

First group of components is production equipment layout with optimized 6 lines that isrepresented by frames of bikes. Second group consist from shown in Fig. Decomposition of Technological Operations and LayoutRedesign Broad set of working activities done in a manufacturingdepartment for a given assortment of parts to be processed can 5. On the other hand, transforming of current production equipment layout to 6 lines led to improvement of more important economical aspects in a company.
