Concrete is a building material, which in many cases fulfills the requirements for high sustainability. Industrial by-products, e. g. fly ash or silica fume, are used for improving the fresh and hardened properties of concrete, blast furnace slag for cement production, but also concrete by itself can be used as aggregate to produce strong and durable concretes. In this contribution examples of ...

Many recent antitrust cases concern aftermarkets: markets for goods or services used together with durable equipment but purchased after the consumer has invested in the equipment. Examples include computer parts, software upgrades, repair manuals, and training. Durable goods manufacturers are often the dominant providers of aftermarket products. The cases involve a variety of alleged anticompe...

Using publicly available aggregate data at an online retailer, we study how consumers search for durable goods. Specifically, we investigate the search patterns when, as is common with durable products, the total set of options consumers can choose from is very large. To study search patterns, we propose to analyze our aggregate data by defining a product network, consisting of the products and...

We study inventorymanagement problemswhere demands are revealed incrementally and procurement decisionsmust bemade before the demands are realized. There are no probabilistic distributions nor nontrivial bounds to characterize demands. We consider two cost minimization problems: (1) perishable products with lost sales and (2) durable products with backlogged demand. In both problems, costs are ...

The sharing economy will blur the distinctions between renting and owning a wide variety of durable products. The first great entrepreneurial (Neolithic) revolution transformed hunter-gatherers into fixed agriculturalists. The second (Industrial) revolution dramatically reduced the costs of owning products. The third (Transactions Costs) revolution will reduce the costs of exchange, fostering a...

This year's winners include a mix of important new products that are leading the marketplace, ranging from state-of-the-art VR display, to ultrathin durable glass, high-performance touchscreen controller, leading-edge TV products, and an innovative laptop/tablet.

Due to the introduction of extended producer responsibility, Original Equipment Manufacturers are forced to set up a reverse logistic system for their 'own' discarded products. As part of this set-up, they have to determine strategies for the recovery of these products. In some of our previous works, we have described OR-optimisation models that give decision support in determining optimal reco...

Smoked anchovy is a product that very popular with consumers for several reasons, among others: high nutritional value and vitamin, long shelf-life compared to other durable fish products durable, unique taste, source of calcium not easily soluble in water, so consuming it can prevent bone loss. processing Buton still traditional method, which may result lack attention quality. There are four s...

Durable products are characterized by their modular structured design as well as their long life cycle. Each class of components involved in the multi-indenture structure of such products requires a different recovery process. Moreover, due to their long life cycle, the return flows are of various quality levels. In this article, we study a closed-loop supply chain in the context of durable pro...
