The biggest software development companies conduct daily more than hundreds deployments which influence currently operating IT (Information Technology) systems. This is possible due to the availability of automatic mechanisms which are providing their functional testing and later applications deployment. Unfortunately, nowadays, there are no tools or even a set of good practices related to the problem on how to include IT security issues into the whole production and deployment processes. This paper describes how to deal with this problem in the large mobile telecommunication operator environment.
A novel approach for treating the uncertainty about the real levels of finished products during production planning and scheduling process
is presented in the paper. Interval arithmetic is used to describe uncertainty concerning the production that was planned to cover potential
defective products, but meets customer’s quality requirement and can be delivered as fully valuable products. Interval lot sizing and
scheduling model to solve this problem is proposed, then a dedicated version of genetic algorithm that is able to deal with interval
arithmetic is used to solve the test problems taken from a real-world example described in the literature. The achieved results are compared
with a standard approach in which no uncertainty about real production of valuable castings is considered. It has been shown that interval
arithmetic can be a valuable method for modeling uncertainty, and proposed approach can provide more accurate information to the
planners allowing them to take more tailored decisions.
The issue in the title is known and is being analyzed for a long time, however its
complexity makes the setting of both – the future of it and contemporary form
– emerge a lot of questions marks. I do not intend to leave most of them aside.
I do make an attempt however to present its complexity and as well the importance
in the reflextion upon life and activity of scholars. In these remarks I do
recall several ways of presenting it and do make an attempt to stress out those
of research possibilities which may lead to interesting outcomes. In the end part
of the remakrs I do present some of them. I treat this step as an invitation to
further discussion on the sensibility and anger of scholars.
The paper presents the results of experimental validation of a set of innovative software services supporting processes of achieving, assessing and maintaining conformance with standards and regulations. The study involved several hospitals implementing the Accreditation Standard promoted by the Polish Ministry of Health. First we introduce NOR-STA services that implement the TRUST-IT methodology of argument management. Then we describe and justify a set of metrics aiming at assessment of the effectiveness and efficiency of the services. Next we present values of the metrics that were built from the data collected. The paper concludes with giving the interpretation and discussing the results of the measurements with respect to the objectives of the validation experiment.
Research focused on integration of machine operators with information flow in manufacturing process according to Industry 4.0 requirements are presented in this paper. A special IT system connecting together machine operators, machine control, process and machine monitoring with companywide IT systems is developed. It is an answer on manufacture of airplane industry requirements. The main aim of the system presented in the article is full automation of information flow between a management level represented by Integrated Management IT System and manufacturing process level. From the management level an information about particular orders are taken, back an on-line information about manufacturing process and manufactured parts are given. System allows automatic identification of tasks for machine operator and particular currently machined part. Operator can verify information about process and tasks. System allows on-line analyzing process data. It is based on information from machining acquired: machine operator, process and machine monitoring systems and measurement devices handled by operator. Process data is integrated with related order as a history of particular manufactured part. System allows for measurement data analysis based on Statistical Process Control algorithm dedicated for short batches. It supports operator in process control. Measurement data are integrated with order data as a part of history of manufactured product. Finally a conception of Cyber-Physical Systems applying in integrated Shop Floor Control and Monitoring systems is presented and discussed.
