Abstract

Purpose

The purpose of this paper is to propose a decision support system (DSS) that stabilizes the flow of fixtures in manufacturing systems. The proposed DSS assists decision-makers to reuse or adapt the available fixtures or to manufacture new fixtures depending upon the similarity between the past and new cases. It considers the cost effectiveness of the proposed decision when an adaptation decision is passed.

Design/methodology/approach

The research problem is addressed by integrating case-based reasoning, rule-based reasoning and fuzzy set theory. Cases are represented using an object-oriented (OO) approach to characterize them by their feature vectors. The fuzzy analytic hierarchy process (FAHP) and the inverse of weighted Euclidean distance measure are applied for case retrieval. A machining operation is illustrated as a computational example to demonstrate the applicability of the proposed DSS.

Findings

The problems of fixture assignment and control have not been well-addressed in the past, although fixture management is one of the complex problems in manufacturing. The proposed DSS is a promising approach to address such kinds of problems using the three components of an artificial intelligence and FAHP.

Research limitations/implications

Although the DSS is tested in a laboratory environment using a numerical example, it has not been validated in real industrial systems.

Practical implications

The DSS is proposed in terms of simple rules and equations. This implies that it is not complex for software development and implementation. The illustrated numerical example indicates that the proposed DSS can be implemented in the real-world.

Originality/value

Demand-driven fixture retrieval and manufacture to assign the right fixtures to planned part-orders using an intelligent DSS is the main contribution. It provides special consideration for the adaptation of the available fixtures in a system.

Abstract

Purpose

This paper aims to propose a theoretical decision support framework, which integrates artificial intelligence (AI), discrete-event simulation (DES) and database management technologies so as to determine the steady state flow of items (e.g. fixtures, jigs, tools, etc.) in manufacturing.

Design/methodology/approach

The existing literature was carefully reviewed to address the state of the arts in decision support systems (DSS), the shortcomings of pure simulation-based and pure AI-based DSS. A conceptual example is illustrated to show the integrated application of AI, simulation and database components of the proposed DSS framework.

Findings

Recent DSS studies have revealed the limitations of pure simulation-based and pure AI-based DSS. A new DSS framework is required in manufacturing to address these limitations, taking into account the problems of flowing items.

Research limitations/implications

The theoretical DSS framework is proposed using simple rules and equations. This implies that it is not complex for software development and implementation. Practical data are not presented in this paper. A real DSS will be developed using the proposed theoretical framework and realistic results will be presented in the near future.

Originality/value

The proposed theoretical framework reveals how the integrated components of DSS can work together in manufacturing in order to determine the stable flow of items in a specific production period. Especially, the integrated performance of case-based reasoning (CBR) and DES is conceptually illustrated.

Abstract

The process of managing the design and construction of a project on behalf of a client may be analysed using project management theory based on a contingency approach. The analysis provided by this approach, whilst useful for understanding the interaction of the parts of the system, the functions of project management and the effectiveness of the organization structure, may be limited by not incorporating an economic explanation of how a project organization structure is chosen. The transaction cost approach to the study of economic organization may provide a theoretical basis for such an explanation. This approach holds that an understanding of transaction cost economizing is central to the study of organizations as it determines whether functions are provided by the market or by hierarchy. This paper seeks to explore the relationship between these two powerful approaches in explaining the structuring and management of project organizations on behalf of clients and to explain the benefits of combining these approaches in furthering construction project management theory.

Abstract

Investigates the results of research into attitudes towards shopping centre refurbishment. Considers the historical background of retail development and the motivation and requirements for refurbishment. Concludes that development is likely to proceed in two ways: centres with simpler, more durable design; and a return to the department store format.

Abstract

Money can flow accurately everywhere because the words used in transactions — from a deposit in a local bank to settling a debt in a far‐off country — have precise meanings. But accounting, the language of business, does not have an accepted vocabulary. This is sorely needed, both for business and nonbusiness accounting. The new millennium is a good time to take stock.

Abstract

Examines the challenges of conserving modern buildings: size, diversity, forms of ownership, new and cheap materials, changing technology, and rapidly dating fashions. Discusses need to ensure modern building conservation while allowing continued development and use, proposing the conservation management agreement as a way of protecting potentially important buildings. Summarizes that current procedures offer inadequate protection for modern buildings, and that changes must be recognized in order to save post‐war buildings.

Abstract

Examines the development of China′s land management system and the hidden constraints within which a socialist market system is striving to get established. Also examines the rationale behind investment in geographical areas of the PRC and the different trends in foreign investment observed to date. The establishment of real estate markets in China really only commenced in 1978 as a result of China′s drive for modernization. They are, however, struggling to develop against a legacy of central economic planning and the allocation of land by the State to state‐owned enterprises. This legacy eschewed the principles of communism by allocating land without compensation, where the terms of years were deliberately unspecified, where any rights of transfer were left unclear and where the obligations and rights of land users were not clearly defined. Since 1988, successive legislation and new regulations have sought to drive out these old principles and replace them with laws and regulations with which the West may be more familiar. As they relate to construction and land ownership the new regime of legislation is now sufficiently clear to have encouraged foreign investment in China′s real estate development. This period of transition from the old system to a new system of land tenure has nevertheless been a confusing one that has left many pitfalls of which overseas investors should be aware and beware. Markets have developed, however, specifically investment opportunities related to geographical locations, in particular the Pearl River Delta, Shanghai and the Yangtse River Delta and the area in and around Beijing. But other areas are emerging as provinces which will begin to compete.

Abstract

Purpose

This study aims to aid theory building, the use of decision theory (DT) concepts in sustainable supply chain management (SSCM) research is examined.

Design/methodology/approach

An abductive approach considers two DT concepts, Snowden’s Cynefin framework for sense-making and Keeney’s value-focussed decision analysis, in a systematic literature review of 160 peer-reviewed papers in English.

Findings

Around 60 per cent of the papers on decision-making in SSCM come from operational research (OR), which makes explicit use of DT. These are almost all normative and rationalist and focussed on structured decision contexts. Some exceptions seek to address unstructured decision contexts via Complex Adaptive Systems or Soft Systems Methodology. Meanwhile, a second set, around 16 per cent, comes from business ethics and are empirical, behavioural decision research. Although this set does not explicitly refer to DT, the empirical evidence here supports Keeney’s value-focussed analysis.

Research limitations/implications

There is potential for theory building in SSCM using DT, but the research only addresses SSCM research (including corporate responsibility and ethics) and not DT in SCM or wider sustainable development research.

Practical implications

Use of particular decision analysis methods for SSCM may be improved by better understanding different decision contexts.

Social implications

The research shows potential synthesis with ethical DT absent from DT and SCM research.

Originality/value

Empirical behavioural decision analysis for SSCM is considered alongside normative, rational analysis for the first time. Value-focussed DT appears useful for unstructured decision contexts found in SSCM.

Abstract

Purpose

This paper identifies the importance of key factors influencing the quality of CBD office buildings. An office building quality index (BQI) is constructed and its relationship with net rent assessed.

Design/methodology/approach

The importance of 30 property‐specific CBD office building attributes on the quality of CBD office buildings is assessed using a survey of property industry respondents. The analytical hierarchy process procedure is used to determine weights for each of these attributes to construct an office BQI.

Findings

Findings indicate that functionality (31.0 per cent), services (22.6 per cent), access and circulation (16.4 per cent), presentation (13.1 per cent), management (11.5 per cent) and amenities (5.4 per cent) are the order of importance in assessing office building quality. There was found to be a strong functional relationship between office building quality and net rent.

Practical implications

A better understanding of the factors influencing CBD office building quality is determined, with a more effective and practical office BQI developed for benchmarking purposes in property portfolios.

Originality/value

Importance of CBD office building attributes is determined and a new CBD office BQI is developed for practical implementation in the property industry.
