Economic Features of Chemical Leasing

Reliable Accounting in Grid Economic Transactions

In the Grid computing model a remote service is provided by a resource owner to a client. The resource owner executes a client job and charges the client for a corresponding fee. In this paper we discuss the main weakness of many existing models for performing such a kind of transaction, i.e., the strong assumption that both the resource owner and the clients are honest. Then, we propose a new ...

Asynchronous Leasing

Leasing is a very effective way to improve the performance of distributed algorithms without hampering their fault-tolerance. The notion of lease has traditionally been defined using a global notion of real time and was hence strongly tied to synchronous system models. This paper introduces a notion of lease object devised for an asynchronous system model. We give precise properties of our leas...

Facility Leasing with Penalties

In this paper we study the facility leasing problem with penalties. We present a primaldual algorithm which is a 3-approximation, based on the algorithm by Nagarajan and Williamson for the facility leasing problem [NW13] and on the algorithm by Charikar et al. for the facility location problem with penalties [CKMN01].

Connected Facility Leasing Problems

We study leasing variants of the connected facility location problem, in which we wish to connect a set of clients to facilities, and facilities are connected via core edges, whose cost is a scale factor times the cost of a simple edge. We identify two aspects of the problem that can lead to different variants: (a) if there is a single or multiple commodities, and (b) if we lease facilities and...
