Digital product passports have been proposed as a policy instrument to enable decision-making throughout life cycles in favour of circular economy. However, due nascent conceptualisation and weak industrial embeddedness, the contents such an are source uncertainty. Situated mechatronics context, this multiple-case study explores data needs for digital passports. Extant research reveals seven cl...

background: the main object of this experimental work was to practise laboratory production both adult and the larval stage of hymenolepis diminuta with conventional modification to make further studies easier. materials & method: adults h. diminuta were collected from urban rats in tehran, iran. the beetles became infected using blended gravid segments with flour as bait. cysticercoids have be...

there are many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms. the mechanism of the meiosis, mitosis and gametes life cycle from the view-point of quantum for human has been represented. the quantum gates have been used to simulate these processes for the first time. the reason of several hundred sperms has been explained in the male too

This paper will describe the multi-board concept, which is a working approach for supporting life cycle oriented design and product quality. Aspects of this concept include construction of a common working environment where multiple display boards depict scenarios of the product life cycle, creating a shared quality mindset amongst designers, and developing creativity and synthesis in product d...

The commercial availability of resources and preliminary products is of essential importance for the industry. One aim of manufacturing companies is to know about structural dependencies in the availability of resources along the entire value chain of their products and to also not only know about environmental impacts of a product but also to have information about the economic life cycle and ...

This paper presents and discusses an analysis of the industrialization and production steps within the Product Life cycle Management (PLM) context. Initially, PLM was focused almost exclusively on the product design, but nowadays, it tends to cover all the steps of the product life cycle. In the same time, the industrialization and the production are not sufficiently integrated into the PLM sol...

selection of appropriate strategies is one of the important principles to achieve profitability in the business models. one of the most important of these strategies, is use of appropriate pricing strategies in order to have the correct and satisfy product pricing process, the factors that affect pricing should be identify and control. plc as organizational factors affecting group is of the mai...

We represent the life cycle of the design of a system in a three-dimensional space with engineering, reengineering, and reuse axes. The three-dimensional model is evolution-oriented. It incorporates not only the evolution that occurs after the product has been produced and delivered, but also three types of system design evolution that take place before the product is produced. Associated with ...
