In this research, we look for the possible reduction in vehicle kilometers that can be obtained when a cooperation of delivery companies has the ability to suggest network improvements to the local government. Different network changes are considered in our research: re-opening existing roads for the vehicles of the cooperation, widening roads in the network or converting existing roads into a one-way...
With increasing servitization efficient delivery of maintenance, repair and overhaul services has become a top priority for many manufacturing companies. But, even though a variety of exact and approximate solution methods have been developed for vehicle routing problems, many manufacturing companies still heavily rely on manual dispatchers with little to no technical support. This paper outlines...
Software maintenance is the activity in which changes occur in the artifacts of a software after delivery, with the purpose of keeping it available, correcting its failures, improving its performance and adapting it to new or modified requirements, according to the needs of Your users. It is an indispensable activity, without which existing systems would quickly become lagging and inefficient for...
This paper reviews ballast water treatment systems regarding functional and operational problems. Ballast water treatment systems (BWTS) could be in failure or under repair. New invented sensors based on flow measurement methodologies should report malfunctions utilizing satellites. This invention is the solution concerning the quality control of ship's ballast water, and this is the system which...
Follow-the-sun is an approach to develop software by handing off the progress to different time zones as the day passes. Hence, this approach allows companies to work on a project 24 hours a day, potentially reducing its time-to-market. However, several challenges, such as time zone differences or handing off work, are often reported. In this paper, we describe a case study on a follow-the-sun approach...
Open Source Software (OSS) has substantial impact on how software-intensive firms develop products and deliver value to the customers. These companies need both strategic and operational support on how to adapt OSS as a part of their products and how to adjust processes and organizations to increase the benefits from OSS participation. This work presents the key insights from the journey that Sony...
"Big data", the word has been mentioned more and more. It is better to say that we are in such an era rather than that the "big data" era is coming. How to use good data, so that the hands of the data collected into a valuable thing, rather than a IoT of data garbage, is the problem that every industry has been thinking about. Every enterprise wants to seize the opportunity to...
Photovoltaic power plants provide alternative and renewable energy. Besides that, the sun is an infinite and costless source, which supplies them. I addition to that, photovoltaic systems has low maintenance costs. Problems may occur if a set of equipment presents the same defect and cannot rely on the manufacturers collaboration to solve it. This paper presents the Megawatt Solar situation, 1 MWp...
According to IEC 60050 definition, live working is “an activity in which a worker makes contact with energized parts or encroaches inside the live working zone with either parts of his or her body or with tools, devices or equipment”. Live working is a worldwide used maintenance and repair methodology in electricity systems. In other words, it is possible to perform maintenance and repair works on...
One of the most interesting spheres which allow steady improvement of the quality of electricity supply service in the European Union and worldwide, but also in Poland, are the techniques and procedures to ensure reliable maintenance and repairs of the power network, power lines and installations and power equipment without the need to resort to power cuts.
The purpose of this paper is to compare the quality management and safety aspects within the Live working (LW) framework. The study draws upon study carried out among the Slovenian electrical distribution and international study which was carried out among Slovenian and foreign LW experts. The results of the first study suggested that health and safety aspects of LW are vital for achieving efficiency...
The paper present the methods used in recent years in the national power grid to operate more efficiently as high voltage equipment. It includes shares of minor maintenance and operation undertaken by our company for management installations. It also briefly describes the results of applying new technologies and the technical analysis performed using such technical data. As part of asset management...
In France, grid live working is supervised by the Ministry of Labour and the Ministry of Industry. In the early sixties, both ministries together with transmission and distribution supply operators (TSO and DSO) decided to create the “Live Working Committee” to entrust all grid live work regulation. Nowadays, the Live Working Committee is in charge of defining work methods, tools and training programs...
In this paper, two closely related problems commonly observed in aircraft hangar maintenance companies are studied: the aircraft hangar maintenance scheduling problem and the parking stand planning problem. Recently, in order to reduce operating costs in airline companies, outsourcing aircraft heavy maintenance activities to a third-party maintenance company has been gaining greater traction. In a...
Live work training centres are unique places where electricians learn and develop their professional skills, but also a place where instructors use the latest andragogy approaches and techniques to transfer knowledge. Experts for live work education and training are rare and valuable human resource of every company. Being faced with retirement and other natural workmen fluctuation companies need to...
Until 1976, the Portuguese electrical sector was fragmented into several companies operating at regional or even local scale. In the aftermaths of the April Revolution of1974, there was large-scale nationalization program to which the electrical sector was no exception. Electricidade de Portugal (EDP) was created in 1976 with the fusion of 13 nationalized companies. Several development programs were...
There is a vast growth of generated event data being collected and stored by organizations. Within the field of Process Mining, this data has been used to discover, analyze and enhance processes from different domains. For this purpose there are hundreds of techniques available in different tools. These techniques are mostly focused on single processes. On the other hand, there are several proposals...
Since the deceleration of the markets of infrastructures in developed economies occurred, the growing demand for infrastructure development in semi-developed countries has become more outstanding. Semi-developed countries such as Thailand aims to become a developed country. However, it is stuck in 'semi-developed country trap'. To break through this, Thai people need local industries with high-added...
This paper assesses the economic sides of a grid-connected PV system based on a validated model and the feed in tariff regulation in Jordan. The economic model was built based on a calibrated design model at previous work for authors. An economic analysis is conducted based on a proposed PV plant to cover the Jordan University needs of electricity, considering the Engineering Procurement Construction...
