Abstract

In this paper, we study the non-metric Online Facility Location with Service Installation Costs problem (OFL-SIC), an extension of the well-known non-metric Online Facility Location problem. In OFL-SIC, we are given a set of facilities, a set of services, and a set of requests arriving over time. Each request is composed of a subset of the services. Facilities are enabled to offer a subset of the services when being opened and an algorithm has to ensure that each arriving request is connected to a set of open facilities jointly offering the requested services. Opening a facility incurs an opening cost and for each offered service, there is a service installation cost that needs to be paid if the algorithm decides to install the service at the facility. Connecting a request to an open facility incurs a connecting cost, which is equal to the distance between the request and the facility. The goal is to minimize the total opening, service installation, and connecting costs. We propose the first online algorithm for non-metric OFL-SIC and show that it is asymptotically optimal under the standard notion of competitive analysis which is used to evaluate the performance of online algorithms.
