We investigate how a supply chain involving a risk-neutral supplier and a downside-risk-averse retailer can be coordinated with a supply contract. We show that the standard buy-back or revenue-sharing contracts may not coordinate such a channel. Using a definition of coordination of supply...

Call blockage may incur large losses in areas prone to traffic accidents. We formulate an optimisation problem that chooses base station locations and assign channels to them so as to minimise the overall installation and call blockage costs. Since this problem is a difficult non-linear integer...
