Population with immigration: Turkey and the EU. Does a young population remedy to the aged?

Annual population growth rate in Turkey is as high as 1.1 per cent, while many EU countries have shrinking, and hence ageing, populations. In this paper we consider an age-structured population that consists of female natives and Turkish immigrants into the EU. Immigrants’ fertility and mortality schedule may differ from that of EU natives, their children may adopt it. We apply a discrete-time Leslie-type model which allows for immigration and the study of its long-run effects. We examine the contribution of EU natives and Turkish immigrants to the EU population in terms of age-specific reproductive values which measure the value of one female of a given age as a seed for future population growth. Genealogies are derived in terms of the realisations of a corresponding Markov chain running backward in time

Prototype resupply scheduler

Resupply scheduling for the Space Station presents some formidable logistics problems. One of the most basic problems is assigning supplies to a series of shuttle resupply missions. A prototype logistics expert system which constructs resupply schedules was developed. This prototype is able to reconstruct feasible resupply plans. In addition, analysts can use the system to evaluate the impact of adding, deleting or modifying launches, cargo space, experiments, etc
