The Moment

PurposeThis paper aims to determine the stage of the life cycle where the trucks of a waste collection fleet from a Colombian city are located through a reliability approach. The reliability analysis and the evaluation of curve of operational costs allow to know the moment in which it is necessary to make decisions regarding an asset, its maintenance or possible replacement.Design/methodology/approachFor a dataset presented as maintenance work orders, the time to failures (TTFs) for each vehicle in the fleet were calculated. Then, a probability density function for those TTFs was fitted to locate each vehicle in a region of the bathtub curve and to calculate the reliability of the whole fleet. A general functional analysis was also developed to understand the function of the vehicles.FindingsIt was possible to determine that the largest proportion of the fleet was in the final stage of the life cycle, in this sense, the entire fleet represent critical assets which in most of cases could be worth replacement or overhaul.Originality/valueIn this study, an address is exposed for the identification of critical equipment by reliability and statistical analysis. This analysis is also integrated with the maintenance management process. This is a broadly interested topic since it allows to support the maintenance and operational decision-making process, indicating the focus of resource allocation all over the entire asset life cycle.

Multiple Case

PurposeThe aim of this paper is to analyze the life cycle of family-owned hotels in the maturity phase from the integration of theoretical models for family-owned tourism businesses.Design/methodology/approachA qualitative multiple case study was used to analyze four mature family-owned hotels through eight interviews and four observation guides with an abductive method. Three axes were analyzed; the ownership with the Gersick model, the family with the Tobak and Nábradí model and the business with the Butler tourist areas model to identify whether they are going through the consolidation stage, stagnation, rejuvenation or decline within its maturity.FindingsThe cases studied evolve in the three axes. In the business axes, two go through the stagnation stage, another in decline and the last in consolidation; all remain under controlling owners. In the family, there are different generations in charge. The boost to the destination plays a key role as a force for deterministic change in the internal transformation of these organizations, and to remain in consolidation, discontinuous changes and voluntaristic actions are necessary.Originality/valueFamily businesses seek longevity, although a low percentage reaches maturity. This research proposes the integration of life cycle models to understand its development in the axes of family, ownership and business, where aspects of the tourism industry are considered and allow the stage identification through which it passes in maturity, supporting internal decision making.

AbstractThis paper investigates the design and development of bio-inspired suture pins that would reduce the insertion force and thereby reducing the pain in the patients. Inspired by kingfisher's beak and porcupine quills, the conceptual design of the suture pin is developed by using a unique ideation methodology that is proposed in this research. The methodology is named as Domain Integrated Design, which involves in classifying bio-inspired structures into various domains. There is little work done on such bio-inspired multifunctional aspect. In this research we have categorized the vast biological functionalities into domains namely, cellular structures, shapes, cross-sections, and surfaces. Multi-functional bio-inspired structures are designed by combining different domains. In this research, the hypothesis is verified by simulating the total deformation of tissue and the needle at the moment of puncture. The results show that the bio-inspired suture pin has a low deformation on the tissue at higher velocities at the puncture point and low deformation in its own structure when an axial force (reaction force) is applied to its tip. This makes the design stiff and thus require less force of insertion.

Purpose The purpose of this paper is to investigate the adaptations that have been made to traditional courtyard houses (TCHs) in Baghdad, Iraq. The aim is to develop an understanding of various factors in the adaptation of these buildings to suit contemporary lifestyles, which will contribute to the wider field of building adaptability. Design/methodology/approach Empirical evidence was collected through case studies of 12 TCHs in the Al-Kadhimiya area of Baghdad, which involved a physical survey of buildings and semi-structured interviews with 24 occupants. Findings Case study analysis show that building adaptability involves both a change to physical spaces and also to lifestyles; with the latter being more likely when there are limitations in how much change can be made to the physical structure. Research limitations/implications The focus of this research is mainly on users’ adaptation of spaces and therefore does not consider the full range of stakeholders involved in the adaptation process. The findings also only apply to the cases considered and may not be applicable to other house types or locations. Originality/value Studies on building adaptability mostly focus on the ease of change to the building fabric, although the role of users is acknowledged. This study provides insights into the complexity and variety of changes that users can make, which are influenced by lifestyles and driven by the need for comfort. These insights are represented in an adaptation model, which can serve as a basis for further research.

Purpose The purpose of this paper is to analyze Lenovo’s successful acquisition of IBM’s PC division using Ghemawat’s (2001) CAGE framework. It was an acquisition that was so full of symbols that it is difficult to know where to begin. Lenovo’s purchase of IBM in 2005 was first seen as a sign of the rapid growth and expansion of the Chinese economy and its transformation away from the traditional manufacturing base to more high-tech areas. For doomsday merchants in the land of Uncle Sam, it foretold the end of the world domination of the US economy. Despite a considerable number of skeptics at the time, Lenovo was clearly up to the task. Such was the success of the acquisition that by 2015, Lenovo could claim to have grown into the world’s number 1 PC maker, number 3 smartphone manufacturer and number 3 in the production of tablet computers. Design/methodology/approach This paper is a case study. Findings Despite a considerable number of skeptics at the time, Lenovo was clearly up to the task. Such was the success of the acquisition that by 2015, Lenovo could claim to have grown into the world’s number 1 PC maker, number 3 smartphone manufacturer and number 3 in the production of tablet computers. Indeed, by 2014, the firm had enough confidence to add the IBM server business to its portfolio. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.
