manufacturers around the globe are competing for the identification of innovative value propositions to survive in the competitive and complex market. this paper is intended to investigate implementation of value engineering (ve) technique into the product design concept for necessary changes in design of the humidifier system in order to lower unnecessary costs and to increase quality of the p...

mechanical alloying of binary and ternary elemental powder mixtures with the nominal compositions of mg2ni and mg(2-x)mnxni (x= 0, 0.05, 0.10 and 0.15 at. %) were carried out in a planetary ball mill for various milling times of 5, 10, 15, 20, 30 and 60 h. x-ray diffraction and field emission scanning and transmission electron microscopy were used for the characterization of the milled products...

W consider a firm that invests in capacity under demand uncertainty and thus faces two related but distinct types of risk: mismatch between capacity and demand and profit variability. Whereas mismatch risk can be mitigated with greater operational flexibility, profit variability can be reduced through financial hedging. We show that the relationship between these two risk mitigating strategies ...

The design, optimization and better control of refinery processes become possible via dynamic simulation. In this article, a methanol distillation unit with three columns has been simulated to separate methanol from its impurities and water in steady and dynamic states, using commercial softwares. Moreover, it investigates, employing simulink/matlab software, the effect of variable changes on p...

Product lines engineering was born in the 80’s as an economic theory to increase economy of scale. Nowadays, the software product lines approach is promising, encouraging researchers and industrials to collaborate in order to increase software quality and to reduce software development costs. Convincing results have been achieved in specific domains, focusing on constructive (not opportunistic)...

A multiple-market framework is developed to measure the size and distribution of research benefits. The model considers an upstream raw product market and a downstream finished product market and allows for imperfect competition in the intermediary food-processing sector. A central conceptual result is derived: an increase in raw product output is a sufficient condition for costreducing innovat...

T paper investigates the impact of e-waste regulation on new product introduction in a stylized model of the electronics industry. Manufacturers choose the development time and expenditure for each new version of a durable product, which together determine its quality. Consumers purchase the new product and dispose of the last-generation product, which becomes e-waste. The price of a new produc...

The purpose of this study is determine whether and how the flexibility of the workforce is affecting product innovation outcomes of firms responding to their changing environments. Drawing on the resource-based theory of the firm we contribute to the literature distinguishing human resource characteristics from human resource management practices and subdividing the characteristics into functio...

we regard the shearlet group as a semidirect product group andshow that its standard representation is,typically, a quasiregu-lar representation. as a result we can characterize irreducibleas well as square-integrable subrepresentations of the shearletgroup.

I systems and the Internet have facilitated the creation of used-product markets that feature a dramatically wider selection, lower search costs, and lower prices than their brick-and-mortar counterparts do. The increased viability of these used-product markets has caused concern among content creators and distributors, notably the Association of American Publishers and Author’s Guild, who beli...
