Social media to support collaboration in the product life cycle of SMEs

Social media to support collaboration in the product life cycle of SMEs

Clear advantages for SMEs to use open innovation approaches for the generation of new ideas, and the development of new products and services have previously been identified. However, this study identified that social media tools were only used once during the planning and imagination phase, for business development, and customer acquisition. None of the interviewed firms used social media tools during the introduction and definition phase to either gather feedback on their concepts and design, or to test their concepts and prototypes. Although there are benefits in exploiting such methods, SMEs often lack resources (time, cost, knowledge) in order to efficiently use them for innovation purposes, and the first two phases of the product life cycle. The lack of resources forces them to turn towards commonly used and familiar platforms, such as Facebook, LinkedIn, Twitter, and YouTube, to perform marketing and customer service support tasks in the later phases of the product life cycle. In both the systematic literature review and the multiple case studies, SMEs neglect the use of social media tools during the retirement phase. Significant benefits can come from collaboration during this phase. These benefits include, amongst others, improved brand image by recycling outdated products and by continuously offering customer service support, important feedback to remove a product, or simply feedback to initiate ideas to develop new products and start a new product life cycle.

Life cycle analysis in preliminary design stages

Life cycle analysis in preliminary design stages

Key words: Sustainability, Life Cycle Analysis, Eco- Design, Design Process. 1- Introduction The product´s life cycle varies dramatically, from processors embedded in disposable consumer goods to applications requiring maintenance and support for decades. Taking into account the complete product life cycle is a design requirement. It covers from the initial product concept, through its operational period, finishing with the replacement with advanced equipment [K2]. The specific concern areas in a life cycle perspective are: an accurate life cycle economic model to guide engineering tradeoffs, taking into account requirements for logistics and support during the product operational period, and other issues regarding to refurbishing/retiring/discarding the system at the end-of-life. Despite the fact that the "life cycle" term has different meanings for various technical communities, the main idea is to expand the traditional engineering emphasis on the "design cycle" to include optimizing utility, profits, and tradeoffs across the entire lifetime of the product being designed.

Review of Life Cycle Assessment in Agro-Chemical Processes

Review of Life Cycle Assessment in Agro-Chemical Processes

Life Cycle Assessment is a “cradle-to-grave” approach for assessing industrial systems. “Cradle-to-grave” begins with the gathering of raw materials from the earth to create the product and ends at the point when all materials are returned to the earth. LCA evaluates all stages of a product’s life from the perspective that they are interdependent, meaning that one operation leads to the next. LCA enables the estimation of the cumulative environmental impacts resulting from all stages in the product life cycle, often including impacts not considered in more traditional analyses (e.g., raw material extraction, material transportation, ultimate product disposal, etc.) (Ortiz, Castells et al. 2009). By including the impacts throughout the whole product life cycle, LCA provides a comprehensive view of the environmental aspects of the product or process and a more accurate picture of the true environmental trade-offs in product selection and its associated process. The term “life cycle” refers to the major activities in the course of the product’s life-span from its manufacture, use, and maintenance, to its final disposal, including the raw material acquisition required manufacturing the product. Figure 1 illustrates the possible life cycle stages that can be considered in an LCA and the typical inputs/outputs measured (SAIC 2006).

A Systems Engineering-based semantic model to support “Product-Service System” life cycle

A Systems Engineering-based semantic model to support “Product-Service System” life cycle

Moreover, PSS has been passed throughout a transition from the primary after-sale services to the current internet based life cycle solution (Van Ostaeyen et al. 2013). As a result, the competitive capability of companies is not anymore on adding offline services to their product but to propose a smart function or solution to fulfill the customer needs. Additionally, PSS development process is associated with a technological transition in the product “along with its life cycle” as well as service enablers (Scholze et al. 2016). In this matter, Cyber-Physical System (CPS) can accurately describe PSS new technological approach in integrating ICT in product life cycle engineering and advanced services (Boehm & Thomas 2013). Connecting Cyber-Physical System to PSS or function design has been proposed by various researchers (Stark et al. 2014)(Lindström & Karlberg 2017). Providing customized, real-time intelligent services are enabled by CPS for traditional manufacturing systems (Yue et al. 2015). In this matter, the design of intelligent service provided by CPS has a very strong Systems Engineering flavor (Yue et al. 2015). As an example, Schuh et al. (2014) proposed the Cyber-Physical System as an enabler for the tool making industry in the service provision (Schuh et al. 2014). In this proposition, the transition from tool provider to the service provider is a progressive process shown in Figure 6.

Environmental taxation, health and the life-cycle

Environmental taxation, health and the life-cycle

1 Introduction What is the economic effect of environmental taxation when pollution impacts health? Whereas a vast number of theoretical contributions address this question taking the effect of pollution on mortality into consideration, fewer include the effects of pollution on morbidity. Furthermore, those contributions do not model the interaction between pollution and health over the life-cycle. By contrast, we build a model that takes into consideration the evolution of health over the life cycle and its consequences on individual optimal choices. In this framework, the effects of environmental taxation are not limited to the traditional negative crowding-out and positive productivity effects. We show that environmental taxation generates new general equilibrium effects ignored by previous contributions. Indeed, as the environmental tax improves the health profile over the life-cycle, it influences investment in health as well as saving, labor supply and retirement choices. We also show that whether those general equilibrium effects are positive or negative for the economy crucially depends on the degree of substitutability between young and old labor.

Contingent Claims Analysis and Life-Cycle Finance

Contingent Claims Analysis and Life-Cycle Finance

In part II of this paper we apply CCA to the issue of career choices. The ability to change careers over one’s working life is isomorphic with an option to exchange one asset for another. Having this option significantly affects the value of one’s human capital, the largest asset that most individuals possess over much of their adult lives. Choosing the optimal strategy involves selecting an initial career and then switching later in life, if the conditions warrant it. Moreover, the switching option affects the consumer’s optimal portfolio mix of safe and risky assets. CCA

Environmental taxation, health and the life-cycle

We build a model that takes into consideration the evolution of health over the life cycle and its consequences on individual optimal choices. In this framework, the effect of environmental taxation are not limited to the traditional negative crowding-out and positive pro- ductivity effects. We show that environmental taxation generates new general equilibrium effects ignored by previous contributions. Indeed, as the environmental tax improves the health profile over the life-cycle, it influences saving, labor supply, retirement and investment in health. We also show that whether those general equilibrium effects are pos- itive or negative for the economy crucially depends on the degree of substitutability between young and old labor. We complete our the- oretical analysis with numerical examples. Within the range of our parameters, it appears that ignoring those general equilibrium effects results in significantly understating the negative of environmental tax- ation on output per capita and welfare.

Addressing temporal considerations in life cycle assessment

Addressing temporal considerations in life cycle assessment

3.2.1. Inherent variations with flow differentiation Inherent variations can be modelled with temporal differentiation of flows or dynamic modelling. For instance, electricity production ( Messagie et al., 2014 ; Vuarnoz and Jusselme, 2018 ; Walker et al., 2015 ) and its use in buildings ( Collinge et al., 2013b ; Collinge et al., 2018 ; Karl et al., 2019 ; Roux et al., 2016b ; Roux et al., 2017 ; Vuarnoz et al., 2018 ; Walzberg et al., 2019a ), cloud computing ( Maurice et al., 2014 ) and wastewater treatment ( de Faria et al., 2015 ) have all been modelled with such approaches. In different ways, all these approaches convert flows into temporal distributions, thus supplementing temporal properties to the core data of the model components in the LCA frame- work. The applicability of such data in other LCA studies is often limited because the temporal information is valid only for the temporal scope of a given case study. A way to address this limitation is to use a reference “time 0” in the temporal distribution as a period of occurrence relating to a starting period of a process ( Beloin-Saint-Pierre et al., 2014 ; Tiruta-Barna et al., 2016 ). This “time mark” creates process-relative de- scriptions, which can be reused in any period of a life cycle or even for different life cycles. Tiruta-Barna et al. (2016) and Pigné et al. (2020) provided process-relative temporal distribution archetypes for ecoinvent v3.2, applicable to foreground and background datasets. As underlined by Beloin-Saint-Pierre et al. (2014) , the additional efforts needed to provide temporal information for all the flows of LCA data- bases are still signi ficant and the prioritisation of data-gathering re- mains important.

The second life of a product placement in movies: the DVD

The second life of a product placement in movies: the DVD

Product placement in movies Product placements in movies are nearly as old as cinema itself (Turner, 2003; Newell and Salmon, 2004). It consists in putting a product and/or a brand into a movie scene where it can be seen and/or its name heard. The placement can either be paid by the advertiser or result in an exchange of products and/or services such as logistics facilities (Karrh, 1998). Ford paid 30 to 40 millions dollars to place an Aston Martin cars in the James bond named Die Another Day (2002) (Lehu, 2006). But Virgin Cola just gave his product and has not paid to be shown in La boite (2001) from Claude Zidi. Mainly since the end of the 1980’, several researches have contributed to a better understanding of this communication technique coined as “hybrid” by Balasubramanian (1994) since it combines several media techniques. Its positive effect on attitude (Fontaine, 2005), behavior (Daugherty et Gangadharbatla, 2005), and especially its potential impact on brand recall (Brennan, Dubas and Babin, 1999; d’Astous and Chartier, 2000) represent the main core of the research knowledge.

Whitestone (1998) markets its own product on CD-ROM format. The data from both firms provides costing for unit measures for specific North American locations and, like Yardstick for Costing (1997), they follow the North American 16-Division specification format, i.e., Masterformat (1995). Yardsticks for Costing, a Canadian product, contains metric and imperial unit costs for the eight major Canadian cities; however, there are no plans to market an electronic version at this time.

Environmental benefits of life cycle design of concrete bridges

Environmental benefits of life cycle design of concrete bridges

The growing concerns with climate change and the demands for the reduction of greenhouse gas emissions, energy efficiency and conservation of raw materials present considerable challenges to owners, engineers and all construction industries. To address these challenges, there is a need to develop effective approaches for life cycle design and management of highway bridges that will ensure their sustainability over a long planning horizon, in terms of improved physical performance, cost-effectiveness, and environmental compatibility. These optimized designs and management systems should provide the owners with the solutions that achieve an optimal balance between three relevant and competing criteria, namely: (i) engineering performance (e.g. safety, serviceability and durability); (ii) economic performance (minimum life cycle costs, minimum user costs); and (iii) environmental performance (minimum greenhouse gas emissions, reduced materials consumption, energy efficiency, etc.).
