In the newsvendor problem, a decision maker chooses an inventory order quantity prior to the realization of a random demand. The decision maker faces a trade-off between ordering too many and having leftover inventory versus ordering too few and missing out on potential sales. Keeping the net profit structure constant, we study how the timing of the payments affects the inventory decisions. Spe...

BACKGROUND Low molecular weight heparins hold several advantages over unfractionated heparin including convenience of administration. Enoxaparin is one such heparin licensed in the UK for use in unstable coronary artery disease (unstable stable angina and non-Q wave myocardial infarction). In these patients, two large randomised controlled trials and their meta-analysis showed small benefits fo...
