Tenix won the ANZAC Ship Contract in November 1989 to build ten guided missile frigates for the navies of Australia and New Zealand. The ships are planned to have a service life of 25 to 30 years. Within this time period, there will be changes in the operational requirements for these vessels....

The paper studies a flowshop scheduling problem where machines are not available in given time intervals. The objective is to minimize the makespan. The problem is known to be NP-hard for two machines. We analyze constructive and local search based heuristic algorithms for the two-machine case....

This paper extends the Dornbusch model of overshooting exchange rates to discuss both exchange rate and output effects of capital controls that involve additional costs for international asset transactions. We show that, on the one hand, such capital controls have the merit of reducing the...

This paper uses a structural vector autoregression to examine differences in demand and supply shocks and the response to these shocks between EMU member countries and three other groups of countries. The first group includes non-EMU EU countries, the second group EFTA countries and the third...

We solve an optimization problem which arises in the German tax system. Here losses in some period can be tranferred to other periods reducing tax in these periods. Two variants of taxation can be applied. We formulate the problem as a mixed binary mathematical program and solve it via branch...
