Abstract

Purpose

This paper aims to provide a design of intelligent model‐based topology analyzer that can be used to improve plant operation.

Design/methodology/approach

POOM process modeling methodology is proposed to model and partition plant topology so that plant operation can be designed in effective manner as mapped to plant topology partitions. Plant topology is divided into areas based on the operation required and material flow and isolation paths are identified automatically using intelligent algorithm.

Findings

It is possible to define hierarchical plant structure (topology) partitions that can be mapped to plant operation levels, which are described by ANSI/ISA‐S88. In addition, the use of design knowledge can be useful to define conceptual partitions such as Block, which is essential to link design and operation knowledge. Plant operation (jobs) can be flexibly defined in view of plant structure partitions in terms of resources (materials, plant structural areas) required and operation scheduling.

Research limitations/implications

It is important to link to production scheduling to ensure effective use of topology partitions in real time based on available resources. The proposed approach can be improved via the integration with intelligent production scheduling.

Practical implications

Production and manufacturing plants will be able to use the proposed approach to design and validate plant operation and to improve plant maintenance while reducing operation risks by identifying plant structures required for each operation task. The proposed technique can be helpful to engineers and R&D members to consider in their design and investigation for process safety, risk management, and plant operation and management.

Originality/value

The idea of topology analysis is quite new where it is usually implemented using search algorithms without considering domain knowledge and operation structures. This paper proposes a valuable technique to link plant structure with plant operation hierarchies, which is important for design and engineering practices and R&D activities for plant operation.

Abstract

Design audit is a risk reduction process, in situations where large sums are involved and the costs of mistakes could be high. The aim is to increase assurance of performance by anticipating and forestalling potential problems. To be effective and accepted, the design auditor must be objective and demonstrate professional and personal skills, in a manner not very different from those engaged in more familiar forms of audit. The approach is outlined and examples are given.

Abstract

This paper reports on the history of the main Volvo Tuve truck plant in Gothenburg from its beginnings in 1981 until 2002. It focuses on the assembly work involved in the completion of truck chassis carried out by blue‐collar employees. Extensive (physical) alterations during this period have been important for understanding the plants' present design. The various designs of the assembly system, in combination with alterations and changes, have radically reformed the blue‐collar employee's work in a way that, in most respects, had not been intended. The ambitious guidelines, design assumptions and praxis of the early plant design which promoted collective dimensions of work have shifted to ones in which assembly work can be seen more as a set of individualised tasks. Moreover, the plant, which in earlier times had been small‐scale and utilised a heterogeneous assembly systems design, now has been transformed into a large‐scale plant with a homogenous assembly systems design. That is, to be more specific, two rather short assembly lines with intermediate buffers (1980s assembly systems design) were turned into the use of extended assembly lines without intermediate buffers (1990s assembly systems designs). The latter assembly systems were earlier working in coexistence with so‐called assembly docks (small work groups completed their own truck chassis). Lastly, these heterogeneous assembly systems designs were recently changed by further extension of the two main product flows and the assembly docks were closed down (2000s assembly system design). We argue that the choice of assembly systems designs was, and maybe still is, an ad hoc process and not a truly rational process. The history of the Volvo Tuve plant history illuminates how one specific plant can illustrate an uneven line of development with regard to assembly system design, within an organisation which successively has turned more international by an ongoing process of creating one single, larger scale, assembly system design. Thereby leaving behind the characteristics which were once a trademark of the Swedish automotive industry.

Argues that the design of the Volvo Uddevalla plant may be described as a process with an “internal logic” in which design options were eliminated through irreversible design

Abstract

Argues that the design of the Volvo Uddevalla plant may be described as a process with an “internal logic” in which design options were eliminated through irreversible design decisions until only one alternative remained ‐ an unorthodox alternative comprising, for example, long cycle time work never used before for full‐scale production of automobiles. Contends that the most innovative features of the Uddevalla plant ‐ i.e. the detailed layout in the assembly workshops and the corresponding unorthodox production principles used ‐ were in many respects an unanticipated outcome of the design process. Pre‐existing gross layout of the plant as well as the interaction between the materials feeding techniques adopted and the operation of the automated guided vehicle system. When this was perceived by the Volvo managers, the design process had passed the point of no return, i.e. the investments made and lack of time prevented regression to more traditional layouts and production principles.

Abstract

Purpose

The purpose of this paper is to focus on the effects of indoor plants on customers' shopping decisions in the restaurant environment.

Design/methodology/approach

The assumption of the research is that there is a relationship between restaurants where indoor plants are used and the customers' shopping decisions (restaurant entry and purchase). A hypothetical study was performed to test this assumption that was based on the digital images of two different restaurants (restaurant with and restaurant without indoor plants) modelled in a virtual environment. The Likert scale questionnaire used in this study was completed by 335 participants.

Findings

Results indicated that restaurants designed with indoor plants had a more positive effect on the shopping decisions of participants than restaurants designed without indoor plants. The statistically significant results between evaluations of customers and their demographic backgrounds were determined. The male participants with a 26–35 age range showed more positive opinions about the plant designed restaurants than female participants with a 36–55 age range. Also, higher education graduate participants showed more positive opinions about the plant designed restaurant than secondary education graduate participants.

Originality/value

This paper reveals a significant relationship between restaurant design and shopping decisions. Results of the study suggest that retailers and designers may be able to make easily stores more appealing for customers by designing them with indoor plants.

Abstract

Purpose

This paper's main objective is to focus on the water-harvesting ability of plants and try to implement a solution-based method to outline a plant-inspired design framework.

Design/methodology/approach

The current paper aims to provide a step-by-step approach to the biological-inspired design by looking deeply at plants' mechanisms and features to harvest water and conduct a method to learn them in an organized way.

Findings

In addition to the proposed framework, the fundamental water-harvesting principles of plants including increasing condensation, reducing transpiration and facilitating transportation have been extracted by investigating several adaptable plants. The relevant factors related to each of these three principles are introduced and can potentially ease the process of bio-inspiration as it contributes to the findability and understandability of a particular biologic strategy. As a result, this framework can be used to the formation of novel designs in different disciplines. In this process, the development of an architectural design concept is presented as an example.

Originality/value

The current global issue about the shortage of water leads researchers to learn adaptability from nature and increase the demands of using bio-inspired strategies. The novelty of this study is to introduce a water-harvesting design path, which has been presented using a four-step-plant-to-design process. Learning from plants' water-harvesting strategies will contribute to efficiency in different disciplines. The findings of this study have important implications for developing bio-inspired water-harvesting materials and systems. Moreover, the findings add substantially to the understanding of water-harvesting architecture and play an important role in bridging the gap between theory and practice.

Abstract

This paper presents a method for designing a fixed controller, which is able to control in a stable fashion a family of linear time‐invariant n‐th order plants with arbitrary relative degree. This plant family is defined in terms of a nominal transfer function of rational type and bounded variations of the coefficients of numerator and denominator polynomials. The design method is based on the algebraic relationship existing in the model reference adaptive control technique between the true plant parameters, the ideal controller parameters and the model reference parameters. While applying the proposed method, the resulting plant families are broader if compared with other techniques used to design robust controllers.

Abstract

Purpose

Urban landscapes play a significant role in supporting municipal, ecological and social systems. Besides, valuable environmental services and urban green spaces provide social and psychological services, very important for the liveability of modern cities and the well-being of urban residents. It is clear that the area of green space in a city, the method of designing urban landscape and access to urban green space potentially affect the health, happiness, comfort, safety and security of urban dwellers. Urban landscape plays a significant role in providing habitats for wildlife, and an important vegetation type in doing this is species-rich herbaceous vegetation that provides pollen and nectar plus physical habitat for native fauna. Any factor that makes an impression on the urban landscape (such as climate change) will affect people’s lives directly or indirectly. There is a universal consensus that the temperature has increased in most of the world over the past century the investigation of climate change impacts on the urban landscape is the purpose of this study.

Findings

Understanding the process of climate change adaptation is necessary to design plant communities for use in public landscapes. Increased CO2 and air temperature in conjunction with the changing rainfall conditions, as the three important factors of climate change, potentially alter almost all world ecosystems. Climate change provides new opportunities, and in some cases, an obligate need to use non-native plant species in conjunction with native plant species, not only to reduce the side effects of climate change but also to increase the species diversity and aesthetic value in meadow-like naturalistic planting design.

Originality/value

The authors confirm that this work is original and has not been published elsewhere. In this paper, the authors report on the effects of climate change on urban landscape and suggest different kind of solutions to reduce the effects. The paper should be of interest to readers in the areas of landscape architecture, landscape ecologist, landscape planner, landscape managers and environmental designer.

Abstract

Purpose

The combination of desalination technology with renewable energy sources (RES) provides a sustainable approach for increasing potable water availability without imposing negative environmental effects. This paper aims to present the development of a platform, which is an internet-based tool integrating the design optimization of desalination systems with spatial modeling based on a geographic information system (GIS).

Design/methodology/approach

The proposed platform assists decision-makers to select the optimal location and configuration of both the energy- and water-related subsystems of desalination plants that are power-supplied by RES, such that the lifetime cost of the overall desalination plant is minimized. It enables to optimize the desalination plant site selection and sizing with various hybrid power supply (solar, wind, wave and electrical grid power systems) and desalination technologies combinations, while simultaneously exploiting spatial technologies in an internet-based GIS platform.

Findings

A pilot study for the optimal design of stand-alone and grid-connected desalination plants powered by RES is presented, which demonstrates the functionality and features of the proposed platform. It is also shown that a grid-connected desalination plant designed by the proposed software design tool exhibits significantly lower lifetime installation and maintenance costs compared to its stand-alone counterpart.

Originality/value

The proposed platform combines technological, scientific and industrial knowledge with information about societal/political conditions and geo-spatial technologies in a user-friendly graphical interface. Therefore, it provides a design tool enabling its users to secure water supply in a sustainable and economically viable manner.

Abstract

Plant configuration management systems address all phases of the plant’s life cycle, from engineering design, re‐design, maintenance, to operations. However, as yet little research has been reported on plant configuration management information systems analysis. During the past decade, the object‐oriented approach has received much attention in information systems development. This paper describes an object structure for plant configuration management systems analysis. Three major aspects of configuration management (maintenance, re‐design change, and business process) and fundamental types of objects engaged in configuration management are described. The association between these objects is then built through identifying the messages between the objects. Practical application of this framework shows that it is useful for the analysis and design of a plant configuration management information system.
