Abstract

Focuses on the integrated use of simulation tools, particularly discrete‐event simulation, in the design and development of manufacturing systems in Japanese industry. The results are based on questionnaires and visits to seven large Japanese manufacturers and show that most of the visited companies do not use simulation to any large extent, particularly not discrete‐event simulation. Some of the reasons for this are general, while others are specific for Japan. However, the use of simulation is believed to increase in Japanese industry. Furthermore, argues that there is a large potential for increased use of advanced simulation techniques in Japanese manufacturing companies, mainly for two reasons. This would result in improved communication, reduced time‐to‐market and higher flexibility in volume and product‐mix.

Abstract

Proposes to treat social law contracts by covering the two most important aspects of the contract of employment, and also the collective agreement. Covers the contract of employment in full with all the integral laws explained as required, including its characteristics, written particulars, sources or regulations, with regard to employers, are also covered. Lengthy coverage of the collective agreement is also included, showing legal as well as moral (!) requirements, also included are cases in law that are covered in depth.

Abstract

Purpose

The purpose of this paper is to explore how the choice of buying managers to share or limit the sharing of strategic information with their suppliers relates to the presence or absence of goodwill and competence trust in the buyer–supplier relationship.

Design/methodology/approach

An interpretive single case study of a mid-sized retailer was used. In total, 17 semi-structured interviews examining information sharing events were conducted with buying managers, along with the analysis of company documents.

Findings

Goodwill and competence trust have a positive effect on strategic information sharing, yet this study reveals several tactics used by buying managers in the presence of competence trust only. With a lack of established trust, or earlier trust breaches, little to no information sharing occurs.

Research limitations/implications

This study featured cross-sectional data of a single case from the buyer’s perspective. This limits its generalizability, yet provides opportunities to test the findings through longitudinal studies, potentially gathering data from both buyers and suppliers.

Practical implications

Relating which types of information being shared for different forms of trust guides managers’ expectations on which type of trust they wish to build for each of their buyer–supplier relationships.

Originality/value

This study examines the trust and information sharing relationship in more detail, linking different types of trust to categories of strategic information. It also distinguishes between the different concepts of encouraging information sharing and deliberately limiting strategic information sharing.

Abstract

THE catalogue, as a library appliance of importance, has had more attention devoted to it than, perhaps, any other method or factor of librarianship. Its construction, materials, rules for compilation and other aspects have all been considered at great length, and in every conceivable manner, so that little remains for exposition save some points in the policy of the catalogue, and its effects on progress and methods. In the early days of the municipal library movement, when methods were somewhat crude, and hedged round with restrictions of many kinds, the catalogue, even in the primitive form it then assumed, was the only key to the book‐wealth of a library, and as such its value was duly recognized. As time went on, and the vogue of the printed catalogue was consolidated, its importance as an appliance became more and more established, and when the first Newcastle catalogue appeared and received such an unusual amount of journalistic notice, the idea of the printed catalogue as the indispensable library tool was enormously enhanced from that time till quite recently. One undoubted result of this devotion to the catalogue has been to stereotype methods to a great extent, leading in the end to stagnation, and there are places even now where every department of the library is made to revolve round the catalogue. Whether it is altogether wise to subordinate everything in library work to the cult of the catalogue has been questioned by several librarians during the past few years, and it is because there is so much to be said against this policy that the following reflections are submitted.

Abstract

Purpose

The purpose of this paper is to study the use of the additive manufacturing (AM) method, electron beam melting (EBM), for manufacturing of customized hip stems. The aim is to investigate EBM's feasibility and commercial potential in comparison with conventional machining, and to map out advantages and drawbacks of using EBM in this application. One part of the study concerns the influence on the fatigue properties of the material, when using the raw surface directly from the EBM machine, in parts of the implant.

Design/methodology/approach

The research is based on a case study of manufacturing a batch of seven individually adapted hip stems. The stems were manufactured both with conventional machining and with EBM technology and the methods were compared according to the costs of materials, time for file preparation and manufacturing. In order to enhance bone ingrowths in the medial part of the stem, the raw surface from EBM manufacturing is used in that area and initial fatigue studies were performed, to get indications on how this surface influences the fatigue properties.

Findings

The cost reduction due to using EBM in this study was 35 per cent. Fatigue tests comparing milled test bars with raw surfaced bars indicate a reduction of the fatigue limit by using the coarse surface.

Originality/value

The paper presents a detailed comparison of EBM and conventional machining, not seen in earlier research. The fatigue tests of raw EBM‐surfaces are interesting since the raw surface has shown to enhance bone ingrowths and therefore is suitable to use in some medical applications.

Abstract

Purpose

The purpose of this paper is to investigate the mechanism and performance of a potential strategy, which is to enhance turbulence to carry out drag reduction for heavy trucks.

Design/methodology/approach

Enhancing turbulence deflector (ETD) was placed on the roof surface of an ground transportation system (GTS) to investigate the drag reduction mechanism of enhancing turbulence. Transition shear-stress transport improved delay detach eddy simulation model was adopted to simulate the unsteady small-scale flow around the ETD.

Findings

By optimizing the three influencing factors, diameter, streamwise length and streamwise position, the optimized ETD has achieved a maximum drag reduction of 7.04%. The analysis of flow field results shows that enhancing turbulence can effectively suppress flow separation and reduce the negative pressure intensity in the wake region of GTS.

Originality/value

The present work provides another potential possibility for the improvement of the aerodynamic performance of heavy trucks.
