    A Job-Shop Scheduling Model of Software Development Planning for Constraint-Based Local Search

    Software development planning usually does not take any advantage of planning and scheduling techniques involving reasoning about time and resources, which are typical in the manufacturing area. This paper proposes a constraint-based model for the Job Shop Scheduling Problem to be solved using local search techniques. The model can be...

    Applying Business Process Change (BPC) to Implement Multi-Agency Collaboration: The Case of the Greek Public Administration

    A great number of recent studies in the e-government area focus on investigating how technology-induced changes in the public sector connect with the New Public Management (NPM) reform, envisioned by many politicians. Researchers in this field contend that e-government denotes a structural and process-oriented change of governmental organizations, with the...

    A Survey Using Constraints to Decision-Making for Fault Tolerance in Business Processes

    Sometimes the business processes do not work how it is expected. In these cases, a diagnosis process has to be executed to determine the responsible activity or activities of the fault in order to substitute it or them for a correct activity. The aim of this paper is describe the...

    Competitive Intelligence Based on Social Networks for Decision Making

    In previous works a framework has been presented to extract from internet the scientific community interested in a specific topic. The process uses search engines query results and emails address co-occurrences to obtain the invisible colleges and subtopics of a community. This paper presents the use of this technique to...

    SQL Nested Queries in SPARQL

    One of the most powerful features of a query language is the nesting of queries, that is, the possibility of writing in a single expression a query which uses the output of other queries. SPARQL currently does not include any form of nested queries. In this paper, the authors present...

    Min-Energy Broadcast in Fixed-Trajectory Mobile Ad-Hoc Networks

    This paper concerns about mobile ad-hoc wireless networks, but with the added restriction that each radio station has a rectilinear trajectory. The paper focuses on the problem of computing an optimal range assignment for the stations, which allows to perform a broadcast operation from a source station, while the overall...
