dynamicsched

Postscript file available tool for simulating dynamic scheduling

Description

dynamicsched provides a set of simple tools for exploring the efficiency of dynamic and static scheduling. It requires site testing data including phase monitor and opacity data, as it available for many sites now (such as the Chajnantor site in Chile).

Example The following example shows how to use the dynamicsched dynamic scheduling simulator.

include 'dynamicsched.g'
mysched := dynamicsched();
#
# info about teh site testing data
#
mysched.setsitedata(sitedatafile='CH.9506.INT+ALL', headerfile='header.sitedata',
observatory='ALMA', seeinglambda='26.79mm', seeingel='36deg', seeingbaseline='300m'));
#
# theoretical opacity profile
#
mysched.settaudata(tautermsfile='CH.LIEBE.TERMS');
#
# perform scheduling for 100 hours, starting 1 day after the start of the site data file;
# schedule increment is 0.5 hours.
#
mysched.settimes(dt='0.5h', relativestart='1.00d', duration='100.0h')
mysched.setschedcriteria();
mysched.setphasecalinfo();
mysched.setchangeinfo(  azslewrate='2.0deg/s', elslewrate='1.0deg/s', 
changeoverhead='60s');
#
# define the sensitivity of the instrument
#
mysched.setsensitivity(dishdiameter='12m', nantennas=64, npol=2);
mysched.setbandsensitivity(1, 'band1', '1GHz', '100GHz', '8GHz', '30K', 0.80);
mysched.setbandsensitivity(2, 'band2', '100GHz', '300GHz', '8GHz',  '50K', 0.75);
mysched.setbandsensitivity(3, 'band3', '300GHz', '500GHz',  '8GHz', '100K',  0.70);
mysched.setbandsensitivity(4, 'band4', '500GHz', '700GHz',  '8GHz', '200K', 0.60);
mysched.setbandsensitivity(5, 'band5', '700GHz', '1000GHz',  '8GHz', '300K',  0.50);
mysched.viewsensitivity();
#
# create many simulated projects; can control distribution of observing time, 
# frequency, etc
#
mysched.generateprojects(nprojects=100, timemode='2h', timesigma='5h', timemax='20h');
mysched.probview('rating')
mysched.probview('freq')
mysched.probview('radec')
mysched.probview('time')
mysched.saveprojects(projecttable='PROJECTS.SAVE');
#
# actually make a schedule for our simulated projects
#
mysched.schedule();
mysched.saveschedule(scheduletable='SCHEDULE.SAVE');
mysched.done();
#
