Abstract

The application of robotics in manufacturing industry is increasingly spreading to other fields such as service, security and medical, and more recently into orthopedic surgery. Most research projects to date have concentrated on the lighter side of non‐invasive surgery, camera, laser guidance, light cutting and milling through bone. Just as in industrial production and processing applications, the choice of robot and its accompanying control and programming system is absolutely paramount. This simple fact has been justified in recent research dealing with the heavier forms of fracture repositioning robotics in accident surgery. This paper discusses the development of the complete system including robot, end‐effector and sensors.

Abstract

Purpose

Ceramic materials and glasses have become important in modern industry as well as in the consumer environment. Heat resistant ceramics are used in the metal forming processes or as welding and brazing fixtures, etc. Ceramic materials are frequently used in industries where a wear and chemical resistance are required criteria (seals, liners, grinding wheels, machining tools, etc.). Electrical, magnetic and optical properties of ceramic materials are important in electrical and electronic industries where these materials are used as sensors and actuators, integrated circuits, piezoelectric transducers, ultrasonic devices, microwave devices, magnetic tapes, and in other applications. A significant amount of literature is available on the finite element modelling (FEM) of ceramics and glass. This paper gives a listing of these published papers and is a continuation of the author's bibliography entitled “Finite element modelling of ceramics and glass” and published in Engineering Computations, Vol. 16, 1999, pp. 510‐71 for the period 1977‐1998.

Abstract

Purpose

Differential search algorithm (DSA) is a new optimization, meta-heuristic algorithm. It simulates the Brownian-like, random-walk movement of an organism by migrating to a better position. The purpose of this paper is to analyze the performance analysis of DSA into two key parts: six random number generators (RNGs) and Benchmark functions (BMF) from IEEE World Congress on Evolutionary Computation (CEC, 2015). Noting that this study took problem dimensionality and maximum function evaluation (MFE) into account, various configurations were executed to check the parameters’ influence. Shifted rotated Rastrigin’s functions provided the best outcomes for the majority of RNGs, and minimum dimensionality offered the best average. Among almost all BMFs studied, Weibull and Beta RNGs concluded with the best and worst averages, respectively. In sum, 50,000 MFE provided the best results with almost RNGs and BMFs.

Design/methodology/approach

DSA was tested under six randomizers (Bernoulli, Beta, Binomial, Chisquare, Rayleigh, Weibull), two unimodal functions (rotated high conditioned elliptic function, rotated cigar function), three simple multi-modal functions (shifted rotated Ackley’s, shifted rotated Rastrigin’s, shifted rotated Schwefel’s functions) and three hybrid Functions (Hybrid Function 1 (n=3), Hybrid Function 2 (n=4,and Hybrid Function 3 (n=5)) at four problem dimensionalities (10D, 30D, 50D and 100D). According to the protocol of the CEC (2015) testbed, the stopping criteria are the MFEs, which are set to 10,000, 50,000 and 100,000. All algorithms mentioned were implemented on PC running Windows 8.1, i5 CPU at 1.60 GHz, 2.29 GHz and a 64-bit operating system.

Findings

The authors concluded the results based on RNGs as follows: F3 gave the best average results with Bernoulli, whereas F4 resulted in the best outcomes with all other RNGs; minimum and maximum dimensionality offered the best and worst averages, respectively; and Bernoulli and Binomial RNGs retained the best and worst averages, respectively, when all other parameters were fixed. In addition, the authors’ results concluded, based on BMFs: Weibull and Beta RNGs produced the best and worst averages with most BMFs; shifted and rotated Rastrigin’s function and Hybrid Function 2 gave rise to the best and worst averages. In both parts, 50,000 MFEs offered the best average results with most RNGs and BMFs.

Originality/value

Being aware of the advantages and drawbacks of DS enlarges knowledge about the class in which differential evolution belongs. Application of that knowledge, to specific problems, ensures that the possible improvements are not randomly applied. Strengths and weaknesses influenced by the characteristics of the problem being solved (e.g. linearity, dimensionality) and by the internal approaches being used (e.g. stop criteria, parameter control settings, initialization procedure) are not studied in detail. In-depth study of performance under various conditions is a “must” if one desires to efficiently apply DS algorithms to help solve specific problems. In this work, all the functions were chosen from the 2015 IEEE World Congress on Evolutionary Computation (CEC, 2015).

Abstract

Applying social concepts to the social relations that the entrepreneur maintains, this research seeks to identify the impact of these relationships, and the learning that might result from them, on the decision‐making process. A social and conversational model of experiential learning is put forward, where learning and influence are seen to emerge as part of an ongoing negotiated process. This argument complements Kolb's “fundamentally cognitive” theory of experiential learning, by challenging the view that the learner should be viewed as an “intellectual Robinson Crusoe”, and stating that even when an individual reflects and theorises their thoughts have a social character. Data were collected using critical incident technique through one‐to‐one in‐depth interviews over several weeks. The paper goes some way to confirm the importance of networks in the business development process, helping further to define how networks exist. The learning identified, is understood therefore as part of an ongoing negotiated process within a complex network of domestic, voluntary, commercial and professional relations.

Abstract

Purpose

The purpose of this paper is to introduce the concept of timescape and examine its impact on corporate real estate strategy, i.e. the people, process, space and technology elements of strategy.

Design/methodology/approach

This paper utilises a qualitative approach to analyse secondary data in order to develop a conceptual framework of timescape for corporate real estate strategies.

Findings

Time is an integral part of strategic corporate real estate management. There are seven key elements that make up the timescape for corporate real estate strategies.

Research limitations/implications

This is a conceptual paper and future empirical research should be conducted to validate the propositions made in this paper.

Practical implications

The paper clearly identified the need to incorporate timescape into corporate real strategy formulation. The discussion on the impact of timescape on corporate real estate is useful in providing the impetus for managers who operate in a hyper‐competitive global business landscape to review their existing strategies.

Originality/value

This paper is high in originality as it pioneers the concept of timescape for application within corporate real estate management.

Abstract

Purpose

The purpose of this paper is to investigate the nature of ISO 9000, illustrate how ISO 9000 can be implemented in face of strong resistance to change, and demonstrate how comprehensive work redesign for higher organisational effectiveness can be realised through ISO 9000 implementation.

Design/methodology/approach

A novel model and process for ISO 9000 implementation in an Indian public sector manufacturing industry have been described. After successful implementation in several production units, the model was examined for congruence with well‐known frameworks in Organisation Development (OD).

Findings

The model has congruence with several OD frameworks. It complements OD by harnessing organisational knowledge through creative involvement of organisational members, adopting three‐tier working to involve the organisation at different levels, employing three‐phase execution to sustain organisational members' motivation throughout the programme; and realising comprehensive work redesign while attaining ISO 9000 certification.

Originality/value

The study show‐cases ISO 9000 as an excellent OD intervention.

Abstract

Many managers are experiencing a “quickening” of their decision‐making processes. The globalization of business, the advances in communications technology and increasing demand for prompt data analysis and interpretation have been the primary drivers on the impact of time for decision making. Modifications in the timeline of decision makers affect the development of a corporate global mindset in a complex manner. This leaves top managers groping for a meaningful decision‐making framework that provides rationale to justify their choices under time pressure. In this article, a decisional framework based on the notion of social time or “timescape” is developed. The construct of timescape is captured by seven dimensions: time frame, tempo, temporality, (a)synchronization, sequence, emerging pauses/gaps and simultaneity. Each is examined in a global environment. Within the proposed framework, decision rules are developed relative to the flexibility and responsiveness of managers’ decisions.

Abstract

Purpose

The purpose of this paper is to propose and test a framework to foster safe work behaviour among workers on construction sites.

Design/methodology/approach

The proposed framework identifies two main reasons for unsafe behaviours: “don't know how”, and “don't care”. Technical and safety training is proposed to overcome the former problem, while for the latter it is proposed that organisations systematically apply operant conditioning techniques to promote safety, using organisational behaviour modification. A postal survey of contractors in Singapore was conducted to test the framework. The four tools of operant conditioning theory (positive reinforcements, negative reinforcements, extinction, and punishments) were evaluated.

Findings

Close and strict supervision, sending workers for safety and health training, and imposing fines are found to be most effective methods. Positive reinforcements (both monetary and non‐monetary) have also been found to be effective, while extinction did not receive much support. Other methods that may foster safe work behaviours are also discussed.

Originality/value

Safety on site could be enhanced via training and application of operant conditioning theory.

Abstract

Investigates the premises that small businesses need marketing expertise in order to grow and that undergraduates need more experience of studying small business marketing problems. There is increasing interest in, and importance of, sustainable small business and a move away from the traditional graduate recruitment route into well‐established large businesses. These developments suggest that an opportunity exists for developing new methods of marketing teaching that will aid both graduates and small businesses to gain added value from their marketing knowledge. Two areas area looked at, that small business sustainability and growth potential are enhanced by an increased understanding of marketing, and that business undergraduates’ employment potential will be enhanced by exposure to small business owner/managers and their specific marketing problems. These are looked at in the context of the author’s long involvement in higher marketing education. The conclusion is reached that developing small business consultancy/case studies around specific marketing problems develops new teaching materials, provides the forum for interaction between SME owner/managers and business undergraduates and helps change existing perceptions.
