Simulation of forest harvesting alternative processes and concept design of an innovative skidding winch focused on productivity improvement

In contexts in which mechanized harvesting is limited, such as in the northwestern Black Sea region of Turkey, it is important to improve timber harvesting productivity while preserving operators' safety and reducing environmental damage. This study aims to introduce a methodology in which the harvesting process is simulated with discrete-event simulation (DES) software in order to identify bottlenecks. An alternative process is compared to the original within the DES software, carrying out further steps oriented to the generation of new innovative product concepts. As a case study, the design of an innovative skidding winch is proposed. The development of the product was focused towards customer satisfaction by collecting customer requirements and identifying quality characteristics with a quality function deployment approach. Contradictions identified in the design phase were solved using the TRIZ contradiction toolkit, generating different product concepts. Inventive solutions provided by TRIZ were designed within parametric CAD software. The concepts were compared in a virtual environment, eventually selecting an optimal solution. The results showed that, with the concept adopted, it is possible to achieve a substantial increase in productivity, from 121% to 133%, in terms of kilograms of logs per hour deposited on the landing

The Chain of Quality through Integrated Product Development

Today, it is almost impossible to find a manufacturer who has not been significantly influenced by the quality culture, but it is evident that some are doing more to improve their product quality than others are. The so-called "Chain of Quality" through integrated product development is a useful metaphor since it recognises that quality is a continuing topic of attention throughout the product development process and that discrete, quality related activities in the process are inter-linked. Depending upon how the product development process is modelled, the chain can be viewed as open or closed with single or parallel threads. In this paper, the overall purpose of the chain, the nature and identity of its many links and the relationship of the chain to the product development process will be discussed. In so doing, this paper will present an overall picture of important product development strategies and practices that can have a key impact on product quality

Critical reflections on designing product service systems

In response to unsustainability and the prospect of resource scarcity, lifestyles dominated by resource throughput are being challenged. This paper focuses on a design experiment that sought to introduce alternative resource consumption pathways in the form of product service systems (PSS) to satisfy household demand and reduce consumer durable household waste. In contrast to many other PSS examples this project did not begin with sustainability benefits, rather the preferences of supply and demand actors and the bounded geographical locations represented by two UK housing developments. The paper addresses the process through which the concept PSS were designed, selected and evaluated, alongside the practical and commercial parameters of the project. It proposes the need for a shift to further emphasize the importance of the design imperative in creating different PSS outcomes that reorganize relationships between people, resources and the environment

A Typology of Mass Services: The Role of Service Delivery and Consumption Purpose In Classifying Service Experiences

Purpose — The purpose of this paper is to provide services marketers with a deeper understanding of the elements that characterize mass services. The paper shows that many studies have been conducted within the context of professional and retail services, knowledge of mass service contexts is limited despite the growth of services within this context. Design/methodology/approach — This paper provides a conceptual overview of mass services and develops a typology for mass services based on an extensive review of the services literature. Specifically, the typology developed classifies mass services on the basis of service delivery and purpose. The typology forwarded, therefore, classifies mass services using a two-by-two framework with individual and collective mass services classified as either utilitarian or hedonic in nature. Findings — The typology found in this paper provides a practical insight into the characteristics of services falling into the classification of mass services. The value of the classification is that managers can better understand the unique aspects of mass services, thus, allowing for a better utilization of limited resources. Moreover, the paper provides insights into a service classification that has received limited research emphasis, yet, is attracting increasing industry attention. Originality/value — This paper provides academics and practitioners with a framework that has both tactical and strategic implications. These implications include enhancing the customer experience and thus customer retention, resource management, employee training and service management. Given that such a framework has not been forwarded in the literature, the typology presented in the current paper makes an original contribution to the literature

Service strategy transition : product and service offerings in medical devices

This study explores how, by undertaking customer-oriented service analysis, a company follows a non-linear approach to product-service provision which is contrary to the approach advocated in the servitisation literature. The case study verifies applicability of existing service models using the example of a global manufacturer of medical products. Open-ended interviews serve as the main source of data to reveal the change opportunities for product-service provision. Study findings suggest that customer orientation is the key element causing the change in pattern; while the analysis of consumer operations provides understanding of the planned change initiatives

What is Product-Service Systems (PSS)? A Review on PSS Researches and Relevant Policies

In order to achieve sustainable society, it is necessary to transform industrial structure to the one that does not reduce the Earth's resources. Under this circumstance, a business model of "not selling goods, but selling services" has been expected as a measure of co-existence of business and the environment. This idea, which is called as "Product-Service Systems: PSS" or "Servicizing" etc., has been studied in Europe, the United States and international organisations, and is now studied in Japan. However, the idea of PSS is still not effectively used for policy development.One of the major reasons is that PSS concept itself is under-developed. Under the unclear concept of PSS, researchers are working towards more scientific understanding while policy makers are trying to develop new policy measures, and there is confusion in those communities. In order to develop policy measures, it is necessary to make clear the position of PSS in socio-economic system. This paper overviews previous PSS researches and relevant policy measures conducted in Japan, the US and EU, and tries to grasp the context of researches and policy activities and to find out the agenda of the current status. The characteristics of PSS rest on the innovative relationship between producer and consumer. However, PSS researches are stuck at measurement of environmental loads, and relevant policies tend to be rest on the ones targeting producers. In order to get out of this situation, it is necessary to ask question what is PSS and to make it clear where PSS can be positioned in socio-economic system. PSS is important, because PSS has an element of creating sufficiency as well as eco-efficiency. It is recommended that PSS concept needs to be examined as a research effort, and environmentally sound product policy needs to be systematically organised

What is the new paradigm in product quality?

The current product quality paradigm is founded upon a customer-focused product development process, in which the functionality and behaviour of a product are designed to fulfil the needs of customers, and technological innovation is used to expand the capability and enhance the performance of the product. However, this view of product quality does not reflect the current practices of today's leading manufacturers, who now offer "total solutions" based upon an integrated package of products and services with well defined characteristics tailored to individual needs. Concepts such as globalisation, mass customisation, product branding, e-commerce, and sustainability suggest that a new product quality paradigm is evolving. This paper will discuss our current understanding of product quality issues and outline our vision of the new quality paradigm for product developers
