This paper reviews a cyclic scheduling model of repetitive manufacturing environments consisting of exible machines and multi-stage jobs. We explicitly model two system performance measures, throughput and ow time, while incorporating variability arising from uncertainty in operation processing times. We present an iterative approximation scheme to estimate the two moment behavior of our perfor...

Letter Section Remarks on 'Experimental investigation of non-linear seismic effects'

Beresnev, I.A., 1991. Remarks on 'Experimental investigation of non-linear seismic effects'. Phys. Earth Planet. Inter., 69: 1-3. This letter is in response to the paper by V.S. Solovev entitled 'Experimental investigation of non-linear seismic effects'. We reaffirm that experimental results discussed by us in earlier work and by Solovev can be explained only by the assumption of nonlinear effe...

Letter from the Special Section Editors, Ten Years of Computers, Freedom and Privacy
