An extensible product structure model for product lifecycle management in the make-to-order environment

This paper presents a product structure model with a semantic representation technique that make the product structure extensible for developing product lifecycle management (PLM) systems that is flexible for make-to-order environment. In the make-to-order business context, each product could have a number of variants with slightly different constitutions to fulfill different customer requirements. All the variants of a family have common characteristics and each variant has its specific features. A master-variant pattern is proposed for building the product structure model to explicitly represent common characteristics and specific features of individual variants. The model is capable of enforcing the consistency of a family structure and its variant structure, supporting multiple product views, and facilitating the business processes. A semantic representation technique is developed that enables entity attributes to be defined and entities to be categorized in a neutral and semantic format. As a result, entity attributes and entity categorization can be redefined easily with its configurable capability for different requirements of the PLM systems. An XML-based language is developed for semantically representing entities and entity categories. A prototype as a proof-of-concept system is presented to illustrate the capability of the proposed extensible product structure model

In this paper, a new paradigm of Manufacturing-as-a-Service (MaaS) environment is introduced and highlights the current research challenges in the configuration of customizable products. Furthermore, the latest development of the front-end system is reported with a view towards further work in the research

The Effect of Incorporating End-User Customization into Additive Manufacturing Designs

In the realm of additive manufacturing there is an increasing trend among makers to create designs that allow for end-users to alter them prior to printing an artifact. Online design repositories have tools that facilitate the creation of such artifacts. There are currently no rules for how to create a good customizable design or a way to measure the degree of customization within a design. This work defines three types of customizations found in additive manufacturing and presents three metrics to measure the degree of customization within designs based on the three types of customization. The goal of this work is to ultimately provide a consistent basis for which a customizable design can be evaluated in order to assist makers in the creation of new customizable designs that can better serve end-user. The types of customization were defined by doing a search of Thingiverse’s online data base of customizable designs and evaluating commonalities between designs. The three types of customization defined by this work are surface, structure, and personal customization. The associated metrics are used to quantify the adjustability of a set of online designs which are then plot against the daily use rate and each other on separate graphs. The use rate data used in this study is naturally biased towards hobbyists due to where the designs used to create the data resides. A preliminary analysis is done on the metrics to evaluate their correlation with design use rate as well as the dependency of the metrics in relation to each other. The trends between the metrics are examined for an idea of how best to provide customizable designs. This work provides a basis for measuring the degree of customization within additive manufacturing design and provides an initial framework for evaluating the usability of designs based on the measured degree of customization relative to the three types of defined customizations

Extending the product portfolio with ‘devolved manufacturing’: Methodology and case studies

Current research by the developers of rapid prototyping systems is generally focused on improvements in cost, speed and materials to create truly economic and practical economic rapid manufacturing machines. In addition to being potentially smarter/faster/cheaper replacements for existing manufacturing technologies, the next generation of these machines will provide opportunities not only for the design and fabrication of products without traditional constraints, but also for organizing manufacturing activities in new, innovative and previously undreamt of ways. This paper outlines a novel devolved manufacturing (DM) ‘factory-less’ approach to e-manufacturing, which integrates Mass Customization (MC) concepts, Rapid Manufacturing (RM) technologies and the communication opportunities of the Internet/WWW, describes two case studies of different DM implementations and discusses the limitations and appropriateness of each, and finally, draws some conclusions about the technical, manufacturing and business challenges involved

Integrated Product and Production Platforms for Pharmaceutical Products: Design Thinking for the Development of Personalized Medicines

Treatments, when customized according to individual patient attributes, are in recent yearsreferred to as personalized medicines. Personalized medicines aim at improving the therapeutic outcome of the patient. However, current pharmaceutical production is dominatedby mass production in a batch manner, i.e. producing large volumes of identical products.Uncertainties prevail regarding the ability of current production to respond to the productcustomization need in an economically and technically realizable manner. However,without customized treatment reaching the patient the benefit of personalized medicinescannot be achieved. Hence, a mass customization-paradigm, i.e. economic feasibilitywhen designing, producing and delivering customized pharmaceutical products, is desired.Pharmaceutical product customization has been discussed from a product and productionperspective. These discussions mainly focus either on product or production design.Additionally, the economic feasibility of suggested approaches is not fully explored.Mass customization requires joint consideration of product and production system design.Hence, the aim of this thesis is to explore integrated pharmaceutical product and productionsystem design facilitating a shift toward mass customization-paradigm.Methodologies to design the integrated product and production systems of pharmaceuticalproducts supporting customization are proposed. Set-based concurrent engineering(SBCE) principles are adapted due to the ability of efficient product development.Platform-based design is adapted due to a successful approach to mass customization inmanufacturing industry. Additionally, an integrated design approach to product value assessment is proposed to emphasize the customized pharmaceutical product value.The methodology application is illustrated for oral dosage forms for the purpose of demonstrating refined approaches to integrated design of these. Knowledge regarding oral dosage forms as enablers for personalized medicines is generated.Results show that the adaption of SBCE principles enables efficient consequence analysisof pharmaceutical product designs for production system designs and is accomplished byacquiring a set-based approach to simultaneous assessment of the performance of variousdesigns. Platform-based design enables flexible pharmaceutical product and productionsystem design, thus supporting mass customization. Finally, oral dosage forms embracingmodularized designs provide substantial product design flexibility but affects manufacturingcomplexity and hence, the discussion of product and production system design cannotbe separated

Cloud-based manufacturing-as-a-service environment for customized products

This paper describes the paradigm of cloud-based services which are used to envisage a new generation of configurable manufacturing systems. Unlike previous approaches to mass customization (that simply reprogram individual machines to produce specific shapes) the system reported here is intended to enable the customized production of technologically complex products by dynamically configuring a manufacturing supply chain. In order to realize such a system, the resources (i.e. production capabilities) have to be designed to support collaboration throughout the whole production network, including their adaption to customer-specific production. The flexible service composition as well as the appropriate IT services required for its realization show many analogies with common cloud computing approaches. For this reason, this paper describes the motivation and challenges that are related to cloud-based manufacturing and illustrates emerging technologies supporting this vision byestablishing an appropriate Manufacturing-as-a-Service environment based on manufacturing service descriptions

Organizing for Service Innovation: Best-Practice or Configurations?

In this paper we contrast the notions of best-practice and configurations contingent on environmental conditions. The analysis draws upon our study of 38 UK and 70 US service firms which includes an assessment of the organization, processes, tools and systems used, and how these factors influence variation in the development and delivery of new services. The best-practice framework is found to be predictive of performance improvement in samples in both the UK and USA, but the model better fits the USA than UK data. We analyze the UK data to identify alternative configurations. Four system configurations are identified: project-based; mass customization; cellular; and organic-technical. Each has a different combination of organization, processes, tools and systems which offer different performance advantages. The results provide an opportunity for updating the typologies of operations and adapting them to include services, and begin to challenge the notion of any universal 'best practice' management or organization of new product or service development.service industry, performance improvement, best-practice, alternative system configurations

Design of generic modular reconfigurable platforms (GMRPS) for a product-oriented micro manufacturing system

With the proposition of the concept of product-service systems, many manufacturers are focusing on selling services or functionality rather than products. Industrial production is shifting production models from mass production to mass customization and highly personalized needs. As a result, there is a tendency for manufacturing system suppliers to develop product-oriented systems to responsively cope with the dynamic fast moving competitive market. The key features of such a manufacturing system are the reconfigurability and adaptability, which can enable the system respond to the changeable needs of customers quickly and adaptively. Therefore, one of the challenges for the micro manufacturing system provider has been the design of a reconfigurable machine platform which will provide the functionalities and flexibility required by the product-oriented systems. In this paper, a new micro manufacturing platform, i.e. a generic modular reconfigurable platform (GMRP) is proposed in order to provide an effective means for fabrication of high quality micro products at low cost in a responsive manner. The GMRP-based system aims to be a product-oriented reconfigurable, highly responsive manufacturing system particularly for high value nano/micro manufacturing purposes. To reuse components and decrease material consumption, GMRP is characterized by hybrid micro manufacturing processes, modularity of key components, and reconfigurability of machine platforms and key components. Furthermore, a practical methodology for the design of reconfigurable machine platforms is discussed against the requirements from product-driven micro manufacturing and its extension for adaptive production
