This paper considers the integration of assembly operations and product structure to Cellular Manufacturing System (CMS) design so that to correct the drawbacks of previous researches in the literature. For this purpose, a new mathematical model is developed which dedicates machining and assembly operations to manufacturing cells while the objective function is to minimize the intercellular mov...

product innovation success has very much to do with the development of models ormetaphors that are able to guide actors. one can observe two traditions in thisregard: rational and non-rational models. apparently in the former the model, suchas “development funnel”, is regarded as a mechanism and rigid applicable, picturinginnovation as an orderly, goal-oriented, value-neutral, and systematic pr...

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...

The run length of cracking furnaces is limited by the formation of coke on the internal skin of the reactor tubes. The reaction mechanism of thermal cracking of hydrocarbons is generally accepted as free-radical chain reactions. On the basis of the plant output data and the insight in the mechanisms for coke formation in pyrolysis reactors, a kinetic model describing the coke formation has been...

As the largest online retailer, Amazon has a huge product base and community of reviewers. A lot of work has been done to determine reviewer communities [6], examine the user reviews of products to model opinion evaluation [7], study how information cascades contribute to opinion formation [6] and study product communities to improve recommendation engines. In this paper, we explore how we can ...

Nowadays, the necessity of manufacturers’ response to their customers’ needs and their fields of activities have extended widely. The cellular manufacturing systems have adopted reduced costs from mass-production systems and high flexibility from job-shop manufacturing systems, and therefore, they are very popular in modern manufacturing environments. Manufacturing systems, in addit...

In October 2008, the Department of Justice approved the Delta/Northwest merger, claiming the potential for substantial cost efficiencies with little or no harmful effects on competition. What makes this merger particularly interesting is that Delta and Northwest are codeshare partners. As such, the merger could have varying effects across different product types (pure online versus codeshare). ...
