The Impact

A case study is presented describing an undergraduate MET capstone design project aimed at reducing the measurement variation of rotating imbalance during the testing of vehicular powertrain products. Primary focus involved the redesign of the rotor assembly interfacing the balance machine and the product. The project entailed the implementation of innovative statistical methods discovered during the ongoing applied research activities of the faculty advisor. These methods were conveyed to the students who were charged with their application during the project. Tasks assigned to the students included the evaluation of existing measurement variation, identification of sources of measurement variation, redesign of the test apparatus to reduce the sources of variation, and quantification of the impact of redesign on measurement variation. The redesign of the rotor assembly and the marked reduction in measurement variation resulting from the design changes are described within the paper. The case study provides an example of the successful integration of technology development derived during the advising faculty’s innovative applied research with technology application by students during a successful undergraduate capstone student design experience.

The Impact

A case study is made on the tack driving assembly of a boot and shoe lasting machine, and relates to the impact noise occurring during part of the machine cycle. Much of the noise is radiated due to vibrations at several frequencies of the tack driver lifting lever, which is excited by the direct application of impacts during the tack driving process. An experimental approach in applying noise reduction principles to various components of the assembly has been preferred to a more complex theoretical treatment, since the identification of the mechanism of impact noise generation and its subsequent abatement is directly relevant to most machine designers faced with the possibility of impact noise problems in other types of machinery. Small design changes, based on the knowledge gained from the experimental investigations, have resulted in noise reductions from 10 to 14 dB being achieved.

The Impact

Design changes by owners are common to many construction projects and can cause severe delays if owners do not consider that a change in one part of the project may cause a series of changes in other parts of that project. The impact of a changed component on other unchanged components is known as the “change ripple effect”. To efficiently manage design changes, the ripple effect should be quantified and impact evaluated. This paper presents a building information modeling (BIM)-based quantification model to quantify the ripple effect of owner-requested design changes. The developed model calculates the impact of design changes and their ripple effect on a project’s total duration. After analyzing the ripple effect over time, the model updates the project schedule accordingly. To demonstrate its usefulness and illustrate its essential features, the model is applied to a case study.

Asset Managers

Purpose – The purpose of the paper is to offer insights into university asset management (AM) and describe the impact that the various determinants have on the process of university AM. The process of university AM is influenced by a range of determinants. Design/methodology/approach – A literature review and a case study were used to achieve the research objective. The case study involved two data collection techniques – interviews and document analysis. Findings – Changing conditions of state-run universities, such as decreasing number of students and a tendency to increase the proportion of scientific research activities, require flexible adjustments to the size and structure of the universities’ facility base. Reductions in government grants and increasing maintenance costs of university assets have made it necessary to manage both existing and future assets more effectively to achieve measured improvement of environmental and social performance, to fulfil strategic responsibilities and to create shared value. Research limitations/implications – The paper was limited to one practice case study. Additional cases could be studied to confirm the findings and increase the usefulness of the methodological framework and improve its application. Practical implications – Identifying the various factors that influence the process of university AM would be useful for universities and other public building owners and their decisions-makers, such as chancellors and asset managers. The experience of the Polish market also may support the development of university or public building AM in other countries. Originality/value – The process of optimising of university asset structure proposed in this paper can contribute to the better understanding and management of higher education institutions ' assets and to the greater competitiveness and efficiency of the Polish universities. The work is novel in that it provides insights into university AM and describes various determinants from an external (macro and micro) and internal (connected with the university itself) perspective.

Design And Construction

This paper reviews a ship design and construction case study in the context of the published literature on the design process and its impact on construction. The objective was to explore the factors that impact design and construction lead time and cost. Design and construction managers constantly experience pressure to accelerate the construction start time in an environment characteristic of frequent design changes and rework. Often the construction of the first ships of a series will aggressively overlap the design phase. This investigation assessed a case study that illustrated that as the degree of overlap between design and construction increases, design changes increased ship construction costs and duration. This negates the advantage of trying to reduce lead time by overlapping phases. Before strategies of overlapping are utilized, shipbuilders need to better understand the details of the design process and its integration with other functions to improve design quality and reduce the impact of design changes on manufacturing and construction. It is recommended that when overlapping strategies are considered, design changes and their impact on construction be factored into the decision. A better strategy would be to eliminate design quality issues and design and construction rework.

Abstract Background Organisational performance measurement (OPM) is an evidence-based tool for planning business improvement and creating sustainable competitive advantage. Despite its value, non-acute health charities under-utilise OPM. The purpose of this paper is to provide the rationale and a detailed description of an OPM implementation model developed specifically for non-acute health charities. The aim of this new model is to encourage uptake of OPM in this sector. Methods The authors investigated the understanding and use of OPM in the non-acute health charity sector through a large mixed methods study. Multiple research activities, including PRISMA systematic reviews and two case study evaluations, identified factors and activities that are important for successful implementation of OPM in non-acute health charities. These were then integrated to form an implementation model. Results The resultant implementation model is a methodological tool designed to account for, and respond to, the specificities and strategic management needs of the non-acute health charity sector. It integrates five distinct yet interconnecting components – a theoretical framework; guiding principles; an implementation framework; measurement domains; and a monitoring and improvement tool. Conclusions The innovative OPM implementation model was designed as an evidence-informed approach to support the implementation of OPM in the non-acute health charity sector. It is titled the Non-Acute Health Charities Measurement Advantage Implementation Model (MAIM). Future studies should test the model in different organisational contexts and the impact of OPM on non-acute health charity performance.
