Different uses of a simulation tool in an intermodal container terminal are presented. Initially, the simulation model of the container terminal of La Spezia (LSCT) in Italy is described. Then it is shown its calibration and validation. The resulting model is used as a tool to validate alternative management policies, such as resource allocation and ship loading and unloading policies. The term...

The central purpose of this paper is to present a novel framework supporting the specification and the implementation of configuration management policies for distributed applications. The introduced approach is part of a system called PRISMA (A platform for integrated construction and management of distributed applications). It provides an integrated application development environment compris...

We propose tractable replenishment policies for a multi-period, single product inventory control problem under ambiguous demands, that is, only limited information of the demand distributions such as mean, support and deviation measures are available. We obtain the parameters of the tractable replenishment policies by solving a deterministic optimization problem in the form of second order cone...

Wireless sensor networks are uniquely characterized by tight energy and bandwidth constraints. These networks should be designed to provide enough data to their application so that a reliable description of the environment can be derived, while operating as energy-efficiently as possible and at the same time meeting bandwidth constraints. These goals are typically contradicting and must be bala...

Obligations are generally actions that users are required to take and are essential for the expression of a large number of requirements. For instance, obligation actions may represent prerequisites to gain some privilege (pre obligations), to satisfy some ongoing or post requirement for resource usage (ongoing and post obligations), or to adhere to some privacy or availability policy. Obligati...

Many computer hardware and software architectures buffer data in memory to improve system performance. Volatile disk or file caches are sometimes used to delay the propagation of writes to disk (called delayed writes). While delayed writes improve system performance, volatile caches can cause the loss of vital data during sudden failure. In this study, we investigate managing non-volatile RAM (...

Many concerns would find it useful to have a publicly available database recording exposures to particular substances, with contextual information. The European Union's Registration, Evaluations, Authorisation, and restriction of Chemicals regulation has increased interest in this. It has been suggested that journals should require detailed publication of exposure data with papers. But there ar...
