We consider the problem of resequencing a pre-arranged set of jobs on a moving assembly line with the objective of minimizing changeover costs. A changeover cost is incurred whenever two consecutive jobs do not share the same feature. Features are assigned from a set of job-specific feasible features. Re-sequencing is limited by the availability of offline buffers. The problem is motivated by a...

Signals emitted by moving sources and received at a xed sensor are subject to the Doppler eeect. For narrow-band signals the Doppler eeect amounts simply to a frequency shift. The eeect is more complex when the signals are wide-band. In this paper, a mathematical model for Doppler-shifted wide-band signal is introduced. The model assumes that the wide-band moving source can be represented by a ...

In this section, we outline a theoretical model that we use to rationalize the empirical results reported below. First, the model explains a secular reallocation of employment over time towards more interactive occupations in terms of differences in productivity growth across occupations and inelastic demand. Second, the model predicts that this reallocation is stronger in metro areas than in n...

Business rule models are widely applied, standalone and embedded in smart objects. They have become segregated from information technology and they are now a valuable asset in their own right. As more business rule models are becoming assets, business models to monetize these assets are designed. The goal of this work is to present a step towards business model classification for organizations ...

during the past two decades business and manufacturing have observed significant and radical changes. companies have used automation in the manufacturing, in order to improve quality and competency. it was expected that along with these changes, management accounting systems, which focus on monitoring and analyzing management decisions, should adapt with and encourage the changes. many authors ...

Continuous computing technologies are employed in order to achieve business continuity from the business operations perspective. In the same time, these technologies are the main prerequisite for business agility as agility relies on available information and “always-on” information system that generates it. Business Agility and relations with business continuity technologies are briefly explai...
