Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, the production of mechanical components to be assembled in final products produced in high volumes (e.g. cars, mopeds, industrial vehicles, etc.) has undergone deep changes due to the overall modifications in the way companies compete. Companies must consider competitive factors such as short lead times, tight product tolerances, frequent market changes and cost reduction. Anyway, companies often have to define production objectives as trade-offs among these critical factors since it can be difficult to improve all of them. Even if system flexibility is often considered a fundamental requirement for firms, it is not always a desirable characteristic of a system because it requires relevant investment cost which can jeopardize the profitability of the firm. Dedicated systems are not able to adapt to changes of the product characteristics while flexible systems offer more flexibility than what is needed, thus increasing investment and operative costs. Production contexts characterized by mid to high demand volume of well identified families of products in continuous evolution do not require the highest level of flexibility; therefore, manufacturing system flexibility must be rationalized and it is necessary to find out the best trade-off between productivity and flexibility by designing manufacturing systems endowed with the right level of flexibility required by the production problem. This new class of production systems can be named Focused Flexibility Manufacturing Systems-FFMSs. The flexibility degree in FFMSs is related to their ability to cope with volume, mix and technological changes, and it must take into account both present and future changes. The required level of system flexibility impacts on the architecture of the system and the explicit design of flexibility often leads to hybrid systems, i.e. automated integrated systems in which parts can be processed by both general purpose and dedicated machines. This is a key issue of FFMSs and results from the matching of flexibility and productivity that respectively characterize FMSs and Dedicated Manufacturing Systems (DMSs). The market share of the EU in the machine tool sector is 44%; the introduction of focused flexibility would be particularly important for machine tool builders whose competitive advantage is based on the ability of customizing their systems on the basis of needs of their customers. In fact, even if current production contexts frequently present situations which would fit well with the FFMS approach, tradition and know-how of machine tool builders play a crucial role. Firms often agree with the focused flexibility vision, nevertheless they decide not to pay the risk and efforts related to the design of this new system architecture. This is due also to the lack of well-structured design approaches which can help machine tool builders to configure innovative systems. Therefore, the FFMS topic is studied through the book chapters following a shared mission: "To define methodologies and tools to design production systems with a minimum level of flexibility needed to face, during their lifecycle, the product and process evolution both in the technological and demand aspects. The goal is to find out the optimal trade-off between flexibility and productivity". The book framework follows the architecture which has been developed to address the FFMS Design problem. This architecture is both broad and detailed, since it pays attention to all the relevant levels in a firm hierarchy which are involved in the system design. Moreover, the architecture is innovative because it models both the point of view of the machine tool builder and the point of view of the system user. The architecture starts analyzing Manufacturing Strategy issues and generating the possible demand scenario to be faced. Technological aspects play a key role while solving process plan problems for the products in the part family. Strategic and technological data becomes input when a machine tool builder performs system configuration. The resulting system configurations are possible solutions that a system user considers when planning its system capacity. All the steps of the architecture are deeply studied, developing methods and tools to address each subproblem. Particular attention is paid to the methodologies adopted to face the different subproblems: mathematical programming, stochastic programming, simulation techniques and inverse kinematics have been used. The whole architecture provides a general approach to implement the right degree of flexibility and it allows to study how different aspects and decisions taken in a firm impact on each other. The work presented in the book is innovative because it gives links among different research fields, such as Manufacturing Strategy, Process Plan, System Design, Capacity Planning and Performance Evaluation; moreover, it helps to formalize and rationalize a critical area such as manufacturing system flexibility. The addressed problem is relevant at an academic level but, also, at an industrial level. A great deal of industrial sectors need to address the problem of designing systems with the right degree of flexibility; for instance, automotive, white goods, electrical and electronic goods industries, etc. Attention to industrial issues is confirmed by empirical studies and real case analyses which are presented within the book chapters.

Available in PDF, EPUB and Kindle. Book excerpt: This publication supplements others, referenced herein, which describe various aspects of the very effective flexible production system developed by Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI) for operating shipyards. Their use is described to show how man-hour budgeting for most work is based on certainty. The indices are used to relate man-hours required to physical characteristics of materials that are to be fabricated, assembled, or painted. With extraordinary attention to material definition, starting in basic design, the indices permit constant refinement of manpower requirements as design progress refines material requirements. The consequence is unprecedented control of production through control of material. The indices described herein are as for construction of ships and end products other than ships. When supplemented to address rip-out (disassembly) and open-and-inspect work, they are applicable for overhaul and modernization of naval ships. The indices are corporate experience. A product work breakdown and product oriented material management are essential.

Book excerpt: This dissertation is devoted to the study of flexible production systems. Flexibility refers to the ability to make multiple different products on the same production line. It is a key feature that modern manufacturers seek to serve diversified and volatile customer market. However, most of the existing studies focus on investment cost, flexibility measurement, and scheduling. There is a need for a comprehensive study by taking into account of machine reliability, finite inventory, setup times, and inhomogeneous demands. In this work, we study flexibility in a hierarchical framework: at both the operational level and manufacturing plant planning level. At the operational level, we examine flexible serial production lines with multiple unreliable machines and finite buffers in the views of discrete time and continuous time. We derive closed-form solutions for one- and two-machine systems and develop accurate performance evaluation algorithms for systems at a large scale. To extend the methods, we generalize the analytical study of long flexible production lines to those lines with random setup time during product changeovers. Efficient aggregation algorithms are derived to evaluate line performance of such systems. Using the analytical tools developed, we study system bottlenecks, i.e., the machine and product whose improvement will lead to the largest improvement in system throughput. Various types of bottlenecks are visited, and bottleneck indicators are proposed to avoid complicated calculations and provide managerial insights. The tools are used to develop effective control policies for meeting throughput targets and reducing idle time. At the strategic level, we study production system flexibility measures regarding matching production capacities and demands. Closed-form bounds of demand shortfall, as well as an accurate estimate of the service level, are obtained. Sensitivity analyses of service level on reductions in setup time, downtime and cycle time are carried out, and the impact of new product launch and product correlation on system flexibility, are also investigated. Finally, case studies are introduced to illustrate the applicability of the work in this dissertation. The results of this work provide manufacturing enterprise managers and engineers quantitative tools for flexible system operation management and planning.

Available in PDF, EPUB and Kindle. Book excerpt: Despite over three decades of debate around the nature of human resource management (HRM), its intellectual boundaries and its application in practice, the field continues to be dogged by a number of theoretical and practical limitations. Written by an international team of respected scholars, this updated textbook adopts a critical perspective to examine the core management function of HRM in all its complexity – including its darker sides. Human Resource Management: A Critical Approach opens with a critique of the very concept of HRM, tracing its development over time, and then systematically analyses the context of HRM, practice of HRM and international perspectives on HRM. New chapters commissioned for this second edition look at HRM and the issues of diversity, migration, global supply chains and economic crisis. This textbook is essential reading for advanced and inquisitive students of HRM, and for HRM professionals looking to deepen their understanding of the complexities of their field.

This book was released on 2019-10-28 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the one side, Industrial competitiveness today means shorter product lifecycles, increased product variety, and shorter times to market and customized tangible products and services. To face these challenges, the manufacturing industry is forced to move from traditional management, control, and automation approaches towards industrial cyber-physical systems. On the other side, several emergent engineering approaches and related Information‐Communication‐Control‐Technologies, such as Multi‐Agent-Systems, Service‐Oriented Architecture, Plug‐and‐Produce Systems, Cloud and Fog Technologies, Big Data and Analytics, among others, have been researched during the last years. The confluence of those results with the latest developments in Industrial Digitalization, Systems‐of‐Cyber-Physical-Systems Engineering, Internet‐of‐Things, Internet‐of‐Services, and Industry 4.0 is opening a new broad spectrum of innovation possibilities. The PERFoRM (Production-harmonizEd-Reconfiguration of Flexible Robots and Machinery) approach is one of them. It teaches the reader what it means when production machines and systems are digitalized and migrated into Industrial Cyber-Physical Systems and what happens when they are networked and start collaborating with each other and with the human, using the internet. After a Technology Trend Screening and beyond a comprehensive state-of-the-art analysis about Industrial Digitalization and Industry 4.0-compliant solutions, the book introduces methods, architectures, and technologies applicable in real industrial use cases, explained for a broad audience of researchers, practitioners, and industrialists.
