Book Description
For supervising, controlling the various processes in a business for an effective manufacturing system like vendor - manufacturer relationship, customer manufacturer relationship, shop floor management in the production of goods or services, Operations management plays an important role. Operations management is basically managing the process that converts inputs which is in the forms of raw materials, people, and energy into outputs like goods and/or services. It is a feedback to a manufacturing system that rectify actions and keep the system on track. Therefore the aim of this article is to build stronger manufacturing system for business sustainability in manufacturing enterprises.A manufacturing system is consist of production machines, material handling system, computer system for scheduling and controlling the activities and people for performing different tasks. There are different types of manufacturing systems that have evolved over the years to fulfill the customer requirement in a dynamic and competitive market. Dedicated Manufacturing System (DMS), followed by Flexible Manufacturing System (FMS) and Cellular Manufacturing System (CMS) are the different manufacturing systems developed over the course of last century. With time new market conditions have come up for medium and high-volume manufacturers characterized by: short windows of opportunity for new products, and large fluctuations in product demand. By using various engineering methods like simultaneous engineering and computer-aided design the product development time have been reduced drastically to fulfill the requirement for new products. The ramp-up time and the time in designing and building of production system is today's bottleneck for quality production. It is economical and beneficial for changeable market to develop and produce new products by reducing lead time for manufacturing systems. Flexible manufacturing systems (FMSs) that can produce various types of products but are not fulfill the demand of products when there is a large variations. Because of average performance of FMSs most of the industrialists are not pleased and therefore such type of systems are not taken in to consideration. Because of the lesser product life cycle of many hardware and software components like computers, drives, controllers and softwares the Flexible manufacturing systems (FMSs) become inefficient and outdated. The inefficient production system increases the cost and time in manufacturing of products. Besides that even such type of systems utilizes it's resources fully they are not accepted by rapid changing and growing market. “Because of these disadvantages and developing new market conditions require a new manufacturing approach that enables:The launch of new product models to be undertaken very quickly, Addition of incremental manufacturing capacity as the market grows and New developments in manufacturing technology to be utilized in production”. For benefiting the mass production and allowing the production of any quantity of highly customized products, Reconfigurable Manufacturing Systems (RMS) are considered as the manufacturing system for the coming years.RMS is defined as a system designed to cater for the requirements of a part family by adjusting its hardware and software components rapidly in response to the abrupt changes in the market. RMS being the most promising technology and with its features it has inbuilt capabilities for capacity adjustment, product variety and shorter reconfiguration time. RMS requires research and development in certain key areas: Research and Development issues associated to design at system level, Research and Development issues associated to design at machine level and Research and Development Issues associated to ramp-up time reduction.For maintaining industrial competitiveness performance measures are very important to analyze the behaviour of manufacturing system. To conduct improvement program and to implement manufacturing decisions effectively performance measures are helpful by studying the current state of manufacturing situation, supervising and controlling of operational efficiency. Although there are many performance measures found in literature but the selection of those measures in an RMS environment to fulfill their objectives is not an easy task.The objective of industry to manufacture the desired quantity at the right time by using best possible method but still some improvement is needed in a manufacturing system based on high level of responsiveness. To become responsive the machines are behave as independent modules, where the stoppage/failure of one component does not forced the stoppage/breakdown of the whole machine and its production. The considered systems are multi-state manufacturing systems (MSMS) that can operate different objects simultaneously, and they are permiting paralleling of similar multi-state modular machines (MSMM) in each production stage. MSMS are having machines that are conventionally evaluated as whole entities which consider reliability, expected production rates for system performance.Reconfigurable manufacturing systems are designed using software and hardware modules that can be combined quickly and reliably. To achieve this, system design requires a RMS having following key characteristics: modularity, integrability, scalability, convertibility, customization and diagnosibility. These characteristics relate to the design of production systems, machines, and their controllers. They may also be applicable to manpower resources, and to the enterprise as a whole. The modular approach in a Reconfigurable Manufacturing System is a natural one and has been used in many different contexts of the human endeavor. All the important components in a reconfigurable manufacturing system like softwares, axes, tooling and controllers are modular in nature. These components can be moderated or replaced if necessary to better suit new applications. The life-cycle costs for these types of manufacturing systems is very low because of easy maintenance of modules. New compensation and calibration algorithms result in greater accuracy by integrating in the machine controller. System reconfiguration and setup need to be carried out quickly to be effective. Changing of part programmes, fixtures, tools, degree of freedom (manual adjustment) are comes under convertibility. To achieve this RMS contains new and advanced mechanisms that allow easy reconfiguration, as well as sensing and diagnosable properties that enable ease of calibration of the machines after reconfiguration. Selection of basic modules, and their synthesis methodologies, allow systems those which are easily integrated, diagnosed, converted, and customized. In the present work characteristics of modularity and convertibility have been discussed. An illustration is given to understand the applicability of the modularity and convertibility characteristics in the Reconfigurable manufacturing system for humaninzing work and work environment.

Book Description
The book develops manufacturing concepts and applications beyond physical production and towards a wider manufacturing value chain incorporating external stakeholders that include suppliers of raw materials and parts, customers, collaborating manufacturing companies, manufacturing service providers, and environmental organisations. The focal point of the value chain remains as a manufacturing system and its operations whiles flows of parts/materials and information and services across the supply/value chain tiers are taken into account. The book emphasises on the two innovative paradigms of Reconfigurable Manufacturing Systems (RMS) and the 4th industrial revolution (Industry 4.0) along with their incorporated development. RMS, as a relatively new paradigm, has been introduced to meet the requirements of ‘the factories of the future’, which is aimed by Industry 4.0, though introducing greater responsiveness and customised flexibility into production systems, in which changes in product volumes and types occur regularly. Manufacturing responsiveness can be achieved by RMS through reconfiguring the production facilities according to changing demands of products and new market conditions. The book addresses challenges of mass-customisation and dynamic changes in the supply-chain environment by focusing on developing new techniques related to integrability, scalability and re-configurability at a system level and manufacturing readiness in terms of financial and technical feasibility of RMS. It demonstrate the expected impacts of an RMS design on operational performance and its supply/value chain in the current/future manufacturing environment facing dynamic changes in the internal/external circumstances. In order to establish a circular economy through the RMS value chain, an integrated data-based reconfiguration link is introduced to incorporate information sharing amongst the value chain stakeholders and facilitate grouping products into families with allocation of the product families to the corresponding system configurations with optimal product-process allocation. Decision support systems such as multi criteria decision making tools are developed and applied for the selection of product families and optimising product-process configuration. The proposed models are illustrated through real case studies in applicable manufacturing firms.

Book Description
This book develops innovative techniques from operational research and management science for the design and implementation of a reconfigurable manufacturing system (RMS), and subsequently analyzes and assesses their performance. A reconfigurable manufacturing system (RMS) is a paradigm that can address many of the challenges posed by the modern market. Accordingly, substantial research is now being conducted on RMS, focusing on various levels of decision-making (strategic, tactical and operational). However, as a relatively new research area, there are still only very few books and articles available on reconfigurable manufacturing system design and management. In addition to filling that gap, this book provides a forum for investigating, exchanging ideas on, and disseminating the latest advances in the broad area of RMS applications in today’s industry. Gathering contributions by experts from academia, industry and policy-making, it represents an essential contribution to the existing literature on manufacturing and logistics in general and industry 4.0 in particular.

Book Description
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.
