Abstract:
In this study, the application of a systematic plant layout planning (SLP) to assist the optimum design of process areas and locations is proposed. The number of machines and space requirement in pulley factory is determined. The operation process chart, flow of material and activity relationship chart have been investigated. The relationships between machines, operation sections and material flow are used to determine the suitable position of each activity. The SLP method has been employed to design the two alternative plant layouts and compare the performances between new layout and present layout in term of material flow. The new plant layout is modified by moving a disassembly and surface finish that significantly decrease the distance of material flow, so it is effective increasing production.

Abstract:
This article focuses on the efficient planning involved in the manufacturing plant. Factory simulation software gives a sense of whether or not such a bottleneck would occur if the factory process were laid out as planned. It extrapolates problems of a particular line layout and forecasts the costs of a problem like a bottleneck. The digital factory software allows manufacturers to simulate factory layout digitally, in order to see how the plant would function under the proposed arrangement and to realize potential problems on the line. In addition to robots, employees themselves can be represented in a digitized version. In this way, engineers can figure out where employees should stand on the line and design workstations for them to both optimize their movements and to ensure they are not under any kind of ergonomic stress. Virtual factories can be planned together by people in different locations with the help of software that allows for fly-through.

Abstract:
This paper deals with the problem of finding the optimal plant layout design. Decision-making methodologies based on analytic hierarchy process (AHP) and data envelopment analysis (DEA) approach are applied in the selection of the best plant layout. New layouts are developed, in an efficient manner, based on the systematic layout planning (SLP). By using the multiple criteria, AHP is applied to weigh the qualitative performance measures. DEA is then used to determine the suitable layout design by measuring layouts’ efficiency, using the information of AHP and combining with the quantitative data. The utilization of the proposed procedure is applied to a real data set of a machining precision parts manufacturing company.

Abstract:
Plant layout design is a complex task requiring a wealth of engineering experience. A well-designed layout can extraordinarily reduce various costs, so layout study is of great value. To promote the research depth, plenty of considerations have been taken. However, an actual plant may have several frames and how to distribute facilities and determine the location of them in the different frames has not been well studied. In this work, frames are set as a special kind of inner structure and are added into the model to assign facilities into several blocks. A quantitative method for assigning facilities is proposed to let the number of cross-frame connections be minimized. After allocating the facilities into several blocks, each frame is optimized to obtain initial frame results. With designer decisions and cross-frame flow information, the relative locations of frames are determined and then the internal frame layouts are optimized again to reach the coupling optimization between frame and plant layout. Minimizing the total cost involving investment and operating costs is set to be the objective. In the case study, a plant with 138 facilities and 247 material connections is studied. All the facilities are assigned into four frames, and only 17 connections are left to be cross-frame ones. Through the two optimizations of each frame, the length of cross-frame connections reduces by 582.7 m, and the total cost decreases by 4.7 × 105 ¥/a. Through these steps, the idea of frame is successfully applied and the effectiveness of the proposed methodology is proved.

Abstract:
Plant trialing and marketing assistance programs have become popular in recent years with several state and some regional programs emerging. Successful implementation requires considerable labor, facilities, and monetary resources for evaluation of large numbers of taxa over several years to ensure that plants are well adapted to the region of interest. Research and development funds, dedicated facilities, and cooperator commitment to trialing programs can be limiting during the early years of the programs. Involvement in plant trialing programs allows students to be exposed to plot layout planning, statistical design, plant maintenance, data collection and analysis, and professional communication of trial results. Construction of facilities for conducting plant trials, growing plants for use in trials, trial installation, and maintenance of plants all provide practical hands-on horticultural training. Replicated plant trials provide the latest information on regionally adapted taxa for inclusion in classroom instruction and publications. Plant trialing programs benefit from labor assistance, development of dedicated facilities, and the opportunity to share equipment and supplies among teaching, trialing, and student research projects.

Abstract:
While industrial plant projects are becoming bigger, and global attention to the plant as a construct is increasing, space arrangement in plant projects is inefficient because of the complex structure of required facilities (e.g., complex MEP (mechanical, electrical, and plumbing) installations, specialized tools, etc.,). Furthermore, problems during installation, operation, and maintenance stages caused by inconsistencies between floor plans and actual layout are on the rise. Although some of these conflicts can be addressed through clash detection using BIM (building information modeling), quality BIM models are scarce, especially for existing industrial plants. This study proposes a way to address the complexities caused by changes during plant construction and securing space for the installation of equipment during the construction and lifecycle of built facilities. 3D cloud point data of space and equipment were collected using 3D laser scanning to conduct space matching. In processing the space matching, data were simplified by applying the 3D grid and by comparing the data, easier identification of the space for target equipment was accomplished. This study also proposed a pre-processing method based on sub-sampling that optimizes the point cloud data and verifies the processing speed and accuracy. Lastly, it finds free space for various equipment layouts required in industrial plant projects by space analysis, proposed algorithms, and processes for obtaining the coordinates of valid space for equipment arrangement. The proposed method of this study is expected to help solve the problems derived from arrangement and installation of new equipment in a complex plant site.

Indeed, such evolution has given rise to the so-called intelligent factory. At present, in order to produce customized mass products according to customers' requirements, it is become an important issue the distribution of facilities with the generation of successful layout designs, based on the flexibility, modularity and easy configuration of production systems.This paper proposes a methodology to solve the problem of plant distribution design and redesign based upon a novel modular approach within an industry 4.0 context. Proposed methodology is an adaptation of the "SLP" Methodology (Systematic Layout Planning-Simulation) so-called SLP Modulary 4.0 (systematic planning of the Layout based on a modular vision under a context of Industry 4.0); this methodology incorporates in its structure an integrated design system (IDS) into its structure, which allows collaborative work with different CAD design and simulation tools. For the validation of the proposed methodology, a case study of a coffee processing plant is considered. The distribution design results obtained from the case study prove the benefit and usefulness of the proposed methodology.

Abstract:
Horizontal bar racks used as fish protection measures at hydropower plants have rapidly gained importance in recent years. Despite the large number of installed racks in Europe, systematic investigations of the hydraulic losses and velocity fields were missing. To fill these research gaps, the hydraulic performance of horizontal bar racks was systematically investigated in a laboratory flume for a large number of rack parameters and different hydropower plant layouts. The results of the head loss assessment are published in a paper entitled Head Losses of Horizontal Bar Racks as Fish Guidance Structures, whereas the present paper focuses on the velocity fields. The measurements show that the bar shape, the horizontal approach flow angle, and the clear bar spacing have only a minor effect on the velocity fields. In contrast, bottom and top overlays might enhance the fish guidance efficiency for bottom and surface oriented fish, while the asymmetric downstream velocity field can reduce turbine efficiencies. The hydropower plant layout strongly affects the approach flow field to horizontal bar racks. For block-type hydropower plants, the installation of a dividing pier or partial opening of the spillways improves the flow field for better fish guidance.

Abstract:
In recent years, the concept of a centralized drainage system that connect an entire city to one single treatment plant is increasingly being questioned in terms of the costs, reliability, and environmental impacts. This study introduces an optimization approach based on decentralization in order to develop a cost-effective and sustainable sewage collection system. For this purpose, a new algorithm based on the growing spanning tree algorithm is developed for decentralized layout generation and treatment plant allocation. The trade-off between construction and operation costs, resilience, and the degree of centralization is a multiobjective problem that consists of two subproblems: the layout of the networks and the hydraulic design. The innovative characteristics of the proposed framework are that layout and hydraulic designs are solved simultaneously, three objectives are optimized together, and the entire problem solving process is self-adaptive. The model is then applied to a real case study. The results show that finding an optimum degree of centralization could reduce not only the network’s costs by 17.3%, but could also increase its structural resilience significantly compared to fully centralized networks.

Abstract:
The layout re-arrangement of fashion production lines realizing many small batches is rarely deployed according to well-known engineering procedures. In fact, it would often appear too complex to call a plant engineer for the proper layout design of such small production lines. Rather, it is preferred to apply empirical methodologies when considering, generally, factory know-how, general business needs, safety requirements, and so on. In the present work, the results of a fashion manufacturing line re-layout were compared by analysing the current situation with the solutions provided by a “homemade” company design, both through a systematic layout planning approach and a broader lean reengineering activity. In order to evaluate the effectiveness of each solution, the different alternatives were compared with the help of a discrete event simulator, analysing productivity, transportation times and costs. The result of the case study showed a slight advantage with the lean approach in considering such efficiency indicators. In addition, the lean production methods allowed the designers to identify some inefficiencies that other approaches could not see, since the latter did not focus on production in a holistic way.

Abstract:
This study presents an investigation into the extent to which emerging building information modelling (BIM) can be applied to construction logistics management (CLM). Given the specialist nature of the domains, the study employed an in-depth qualitative interview, whereby six experts were interrogated about their experiences of BIM for CLM. The study found the main applications of BIM on CLM to be the creation of three-dimensional (3D) site layout plans and four-dimensional (4D) coordination of site processes and common user plant, updating the 4D logistics plan as the project progressed and collaboration in BIM-based logistics coordination. Furthermore, there was a consensus amongst interviewees on improvement in site safety, comprehension of logistics information, efficiency on site, and effectiveness of layout planning as the main benefits. Lastly, the lack of training with implications on understanding was one of the main barriers to applying BIM to CLM. The findings from this study have the potential to stimulate the uptake of BIM by construction logistics practitioners. By so doing, the performance construction project delivery can be improved, and waste can be minimised or eliminated.

Abstract:
A new methodology has been proposed to optimize both the planning of preventive maintenance and the time required to perform maintenance in a process plant is presented. In the Plant Maintenance process there is an increased need to make the shop floor layout more easily reachable user pliable. This allows Plant Maintenance staff to focus more on minimizing downtime and increasing productivity. Being more mobile allows them to go from more reactive maintenance to proactive maintenance. In this paper a single facility location problem with multiple relocation opportunities is investigated. The weight associated with each demand point is a known function of distance and time. We consider either rectilinear, or squared Euclidean, or Euclidean distances. The objective function is to minimize the total travelling distance from service center to various machines locations,thereby reducing the total maintenance time.

Abstract:
Horizontal bar racks have been used as trash racks at hydropower plants since the 1920s. With the installation of the first horizontal bar rack bypass system at a hydropower plant as a downstream fish passage facility in 2006, these racks rapidly gained importance as fish protection measures. Since then, they have been installed at more than 100 small- to medium-sized hydropower plants in Europe. Despite the large number of installed racks, systematic investigations of the head losses and velocity fields were missing. On the basis of detailed hydraulic experimentation with a large number of rack parameters and including up-to-date foil-shaped bars, the layout of horizontal bar racks and their hydraulic performance were assessed in the current study. This paper reports the results of the rack head loss investigation, whereas the accompanying paper entitled Velocity Fields at Horizontal Bar Racks as Fish Guidance Structures focuses on the up- and downstream velocity fields. By applying foil-shaped bars instead of rectangular bars, the loss coefficient was reduced by more than 40%, depending on the rack configuration. Bottom and top overlays are used to increase the guidance efficiency for fish, sediments, and floating debris. However, the altered flow field results in increased head losses. A new set of equations is proposed to predict head losses for current horizontal bar racks, including overlays for various hydropower plant layouts. The predictions are compared to literature data.

Abstract:
In the view of optimizing regional power supply and demand, the paper makes effective planning scheduling of supply and demand side resources including energy efficiency power plant (EPP), to achieve the target of benefit, cost, and environmental constraints. In order to highlight the characteristics of different supply and demand resources in economic, environmental, and carbon constraints, three planning models with progressive constraints are constructed. Results of three models by the same example show that the best solutions to different models are different. The planning model including EPP has obvious advantages considering pollutant and carbon emission constraints, which confirms the advantages of low cost and emissions of EPP. The construction of progressive IRP models for power resources considering EPP has a certain reference value for guiding the planning and layout of EPP within other power resources and achieving cost and environmental objectives.

Abstract:
Current stone countertop production process is worn the following problems: long handling distance, long handling time, loose process cohesion, low balance rate, etc. In order to solve these problems, an automatic production line is proposed. In the production line, roller conveyer is used as the logistic system. The selected CNC equipment adopts an open structure and an oblique base. The equipments are arranged into a U-shape line combined with unit layout. In order to increase the flexibility of the production line, the whole production line is divided into two level modules. According to the design rules of the automatic production line, two examples are planned and are simulated based on EM-Plant. The simulation results show that, compared with the current production process, the automatic production line has the following advantages: the transit distance is shortened more than half, the transit time is reduced to about 1/7, and the balance rate increases by 20%, the output is nearly doubled, while the number of workers does not increase.

With the example of the water supply engineering planning of small towns in southern china, the effects of town water consumption forecast, water resource selection, water site choice, pipe network planning on the present engineering planning of water supply were investigated. The analyses show that the water consumption forecast should adopt many kinds of methods to check each other, and finally determine a proper value. To ensure water yield of source water reliable and water quality to meet the requirements are the first principle of the water resource selection. The location of water plant should be determined according to the characteristics of the water source and the hydrological and hydrogeological conditions, in accordance with the relevant requirements specification. The basic requirements of the pipe network layout are as follows: the security of water quality; the reliability of the water volume and water pressure; the operation reliability and the least investment. As a part of the overall planning, the water supply engineering planning should proceed from reality to deal with the relationship of the recent construction and long-term development in order to push small towns economy to a rapid growth.

Abstract:
Warehouse management is a discipline that has gained importance in recent decades. In the era of the Digital Revolution and Industry 5.0, to enable a company to attain a competitive advantage, it is necessary to identify smart improvement tools that help search for warehouse problems and solutions. A good tool to highlight issues related to layout and resource flows is the spaghetti chart which, besides being used to minimize waste according to lean philosophy, can also be used to assess warehouse safety and reliability and improve the plant sustainability. This article shows how to exploit “smart spaghetti” (spaghetti chart automatically generated by smart tracking devices) to conceive improvements in the layout and work organization of a warehouse, reducing the risk of collision between forklifts and improving the operators’ safety. The methodology involves automatically mapping the spaghetti charts (searching for critical areas where the risk of collision is high) and identifying interventions to be carried out to avoid near misses. “Smart spaghetti” constitutes a valuable decision support tool to identify potential improvements in the system through changes in the layout or in the way activities are performed. This work shows an application of the proposed technique in a pharmaceutical warehouse.

Abstract:
A power plant manager has to minimize operation and maintenance (O&M) expenses while ensuring the reliability, safety, and security of supply in order to remain competitive in the global market. The performance of a steam power plant (SPP) is a function of its basic structure (i.e., layout and design), availability (maintenance aspects), operation efficiency (trained manpower), safety and security, and other regulatory aspects. Understanding of its structure will help in the improvement of performance, design, maintenance planning, and so on. A mathematical model using the graph theory and matrix method is developed to evaluate the performance of a coal-based SPP. Detailed methodology for developing a system structure graph (SSG), various system structure matrices, and their permanent functions are described for the boiler of an SPP (a macro level system). Structural interconnections between six systems of boiler are considered for developing an SSG of a boiler. To carry out complete structural modelling and analyses of the boiler, system structure graphs of its six systems and their subsystems are presented. A top-down approach for complete analysis of any system is also given. This method can be extended further for modelling a complete SPP by incorporating a turbogenerator macro system and its subsystems, thus converting real-life SPP from a block diagram into a mathematical model for analysis and synthesis of a power plant from different perspectives.

Abstract:
The engine room is the heart of a ship, and almost all of the main electromechanical equipment that supports the work on board can be found here. Finding a way to arrange the equipment in a small cabin space is an essential factor in the design and construction of a ship. However, in existing research, when an intelligent algorithm is used to optimize the design of a cabin, the established mathematical model is not comprehensive and the solution has not been evaluated. The optimal solution obtained is not feasible for the actual design of a ship. This can lead to unnecessary redesign work, which seriously affects design efficiency and increases design costs. In order to solve the above problems, this paper innovatively refers to a Systematic Layout Planning (SLP) method (normally applied to the layout of plant equipment) to the cabin equipment layout issue. The SLP method is used to quantitatively analyze the adjacency and logistics relationship between devices, and the mutual integration relationship between devices is obtained so that a preliminary layout scheme can be retrieved. The problem model is constructed by considering various factors such as the comprehensive relationship between the equipment and the stability of the cabin, and the corresponding objective function and constraint function are established to further design the variables, operators, and steps of the genetic algorithm. The initial solution obtained from the SLP method is used as part of an initial solution to the genetic algorithm, and the genetic algorithm is used to optimize the problem. Finally, the Analytic Hierarchy Process (AHP) is used to evaluate and optimize several groups of better schemes obtained by running multiple genetic algorithms and select the better schemes. The experimental design proves that the integrated design method has certain feasibility and superiority.

Abstract Higher-precision technologies may increase measurement accuracy and efficiency for operational layout while decreasing total planning costs. Although a number of trials have been completed on the potential implementation of some of these new technologies, few have quantified the benefits of such devices in an operational setting. Unit boundaries for 16 (∼1 ac) units were measured by three surveying techniques, comprising (1) a string box, manual compass, and clinometer; (2) a laser, digital compass, and digital data collector; and (3) a GPS. Collected data were compared to a fourth benchmark method established with a total station. Techniques were statistically analyzed and error distributions were developed at either a unit or an individual data-point scale. Time and cost studies were conducted to determine the overall efficiencies of each technique. Our results should assist forest resource managers in their decisions when selecting alternate measurement tools for collecting spatial data. West. J. Appl. For. 20(2):138–143.

Abstract:
Purpose – The purpose of this paper is to propose a “Reconfiguration Methodology” in manufacturing systems that they can become more economically sustainable and can operate efficiency and effectively. This methodology will allow customized flexibility and capacity not only in producing a variety of products (parts) and with changing market demands, but also in changing and reengineering the system itself. Design/methodology/approach – Reconfigurable manufacturing system (RMS) is a philosophy or strategy which was introduced during the last decade to achieve agility in manufacturing systems. Until now, the RMS philosophy was based changing activities such routing, planning, programming of machines, controlling, scheduling, and physical layout or materials handling system. But the RMS concept can be based on the needed reconfiguration level (NRL), operational status of production systems, and new circumstances (NC). The NRL measure is based on the agility level of the manufacturing systems which is based on technology, people, management, and manufacturing strategies. The components of the manufacturing system design (MSD) consist of production system design, plant layout system, and material handling system. Operational status of production systems includes machine capability (flexibility) and capacity (reliability), production volume or demand, and material handling equipment in addition to the plant layout. The NC are also consisting of new product, developing the existing ones, and changing in demand. Findings – Reconfiguration manufacturing systems from one period to another period is highly desired and is considered as a novel manufacturing philosophy and/or strategy toward creating new sustainable manufacturing systems. A new reconfiguration methodology for the manufacturing systems will be analyzed and proposed. Two Case studies will be introduced. Originality/value – The suggestion of a new methodology of reconfiguration including the NRL (configurability index) and the operational status of manufacturing systems with respect to any circumstance is highly considered. The reconfiguration methodology also provides a framework for sustainability in the manufacturing area which mainly focussed on manufacturing systems design.

The typology of small gardens has been studied, including their characteristics and prevailing features in the architectural and landscaping system of Ekaterinburg. A comparative analysis of international and domestic experiences in creating urban small green spaces has revealed regular patterns in small garden design: the choice of style, image, spatial layout and composition of vegetation. Based on this approach and detailed field surveys of the most characteristic small gardens in Ekaterinburg, their typology is proposed taking into account correspondence to the architectural and landscape environment, location in the urban development, spatial treatment, functional purpose, style, and plant assortment. Classification helped reveal the typological features of these small green spaces and suggest ways to improve their esthetics, comfort, and sustainability allowing for the urban planning and landscaping specifics of Ekaterinburg.

La distribución del espacio causa un alto impacto en el rendimiento de cualquier industria o cadena de procesos. Por ello, el objetivo de esta investigación fue evaluar la distribución en planta de la incubadora de la Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López mediante el algoritmo CORELAP. La metodología empleada, se basa en el método SPL (Systematic Layout Planning). Se identificaron los productos para determinar el orden que llevan los movimientos de los materiales a lo largo de diversas etapas del proceso. Se elaboró un plano con base en la actual distribución de la planta Incubadora mediante el software AutoCAD 2018. Como resultado, se detallan los nueve procesos que se realizan en la incubadora. Se determinó que la distribución en la planta incubadora es de procesos y mediante un diagrama relacional se constató que varias de las relaciones entre las operaciones no tienen importancia entre sí. La aplicación del algoritmo CORELAP demostró que, la actual distribución de la incubadora es adecuada. El enfoque presentado en este estudio es susceptible de usarse en la mejora de los niveles de producción de plantas incubadoras.
