Abstract

Decision makers in the service industry must effectively cope with queuing problems, service capacity optimization, service efficiency and service quality problems. This study proposes a computer simulation‐enabled MCDM framework that integrates computer simulation analysis, Taguchi method, expert opinion and multiple criteria decision making (MCDM) to assist decision makers in coping with decision problems. In this framework, Taguchi method is adopted to reduce the time required for the simulation experiment. Computer simulation analysis is adopted to obtain useful information for rapid decision‐making without interrupting actual production. MCDM is used to select the optimal alternative. The illustrative result is extremely promising.

Abstract

Purpose

The purpose of this paper is to provide a retrospective analysis of computer simulation’s role in accelerating individual innovation adoption decisions. The process innovation examined is Lean Systems Thinking, and the organizational context is the imaging department of an Australian public hospital.

Design/methodology/approach

Intrinsic case study methods including observation, interviews with radiology and emergency personnel about scheduling procedures, mapping patient appointment processes and document analysis were used over three years and then complemented with retrospective interviews with key hospital staff. The multiple data sources and methods were combined in a pragmatic and reflexive manner to explore an extreme case that provides potential to act as an instructive template for effective change.

Findings

Computer simulation of process change ideas offered by staff to improve patient-flow accelerated the adoption of the process changes, largely because animated computer simulation permitted experimentation (trialability), provided observable predictions of change results (observability) and minimized perceived risk.

Research limitations/implications

The difficulty of making accurate comparisons between time periods in a health care setting is acknowledged.

Practical implications

This work has implications for policy, practice and theory, particularly for inducing the rapid diffusion of process innovations to address challenges facing health service organizations and national health systems.

Originality/value

The research demonstrates the value of animated computer simulation in presenting the need for change, identifying options, and predicting change outcomes and is the first work to indicate the importance of trialability, observability and risk reduction in individual adoption decisions in health services.

Abstract

Despite their motivational appeal to learners, innovative and technologically advanced computer simulation games targeting native English speakers frequently remain beyond the competence of ESL learners as independent didactic tools. Guided by Chapelle’s (2001) criteria for determining CALL task appropriateness, this paper illustrates how the popular authentic simulation, The SIMs, can be adapted to enhance vocabulary learning through supporting materials. Adult ESL learners completed a five‐week unit, experiencing different conditions of supplemental materials while completing tasks using The SIMs. The participants received mandatory supplemental materials in one condition, voluntary access to supplemental materials in the second, and no supplemental materials in the third. The results indicate a statistically significant increase in vocabulary acquisition for the first condition. Student feedback suggests the supplemental materials were beneficial for successful task completion. Thus, how authentic computer simulation tasks are structured and supported appears to have a considerable bearing on the appropriateness of the task.

Abstract

Discusses computer modelling and simulation as a decision‐making technique frequently used by all genres of manager in a wide range of disciplines and in all types of organizations. Suggests that for auditors to do an effective job – a competent, quality audit in a timely and efficient way – they must familiarize themselves with the technique, know how it is used in the decision process and be aware of its shortcomings. Explores the many ways computer modelling and simulation are used in the decision process and discusses how the technique was actually used to facilitate several audits. Describes the use of computer modelling and simulation during an audit to validate an auditee‐developed model, simulate the outcome of an auditee′s plans, test an auditee′s in‐place system and, finally, help enhance the credibility of auditor recommendations.

Abstract

Purpose

The purpose of this paper is to focus on the practical knowing that is central in police education. Drawing on perspectives about tacit knowledge and embodied learning (e.g. Merleau-Ponty, 1945/1997; Polanyi, 1966; Argyris and Schön, 1974) as well as empirical examples, this paper discusses the design of and what can be expected from computer simulation training for the development of police students’ professional knowing.

Design/methodology/approach

The discussion is based on lessons learned from working with two different computer simulation training situations designed to prepare the students for an upcoming practical training by facilitating the understanding of complex situations as they should be handled in the physical training situation.

Findings

The experiences from the training sessions showed that the different characteristics of the simulations mediate how the training session was performed, e.g., unplanned trial and error vs focused and attentive, but also group discussions about how to act and appropriate actions in relation to the situation to be solved in the simulation.

Originality/value

Based on the lessons learned from working with the two different computer simulations, it is posited that the use of computer simulations for practical scenario training is a complex endeavor that needs, in various degrees, to be supported by pedagogical steering. The design of computer simulation training (both the simulation and how the training is designed and performed) need to consider the specific aspects that surround tacit knowledge and embodied learning in the “real sense” (anchored to the practical training) to be of relevance for police students development of professional knowing.

Abstract

This presentation is a continuation of the presentation made at IHS 98. The topics remain the same; however, the content is updated to reflect the improvements in both computer software and hardware and some new studies made by Centre for Induction Technology, Inc. (CIT). Several examples are presented that show the results of computer simulation studies and their verification by means of empirical studies. These examples include 1‐D, 2‐D and 3‐D computer simulation of various induction heating systems. Special attention is paid to 3‐D electromagnetic simulation, including a fundamental study of the end and edge effects for induction heating of slabs and the historical perspective of this case.

Abstract

This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming and powder metallurgy are briefly discussed. The range of applications of finite elements on the subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for the last five years, and more than 1100 references are listed.

Abstract

This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming, powder metallurgy and composite material processing are briefly discussed. The range of applications of finite elements on these subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE researchers/users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for 1994‐1996, where 1,370 references are listed. This bibliography is an updating of the paper written by Brannberg and Mackerle which has been published in Engineering Computations, Vol. 11 No. 5, 1994, pp. 413‐55.
