Trading strategies basing on both financial analysis and machine learning techniques are becoming increasingly popular due to their ability to capture micro market price movements and leverage big data. An important class of works are focusing on exploiting the structural relationships between companies for accurate stock price prediction. In this paper we develop an algorithm for learning the parameters...
Background: Understanding and controlling the impact of change decides about the success or failure of evolving products. The problem magnifies for start-ups operating with limited resources. Their usual focus is on Minimum Viable Product (MVP's) providing specialized functionality, thus have little expense available for handling changes. Aims: Change Impact Analysis (CIA) refers to the identification...
In a process collaboration, changes rarely confine themselves to a single company, but can spread over the network of partners, resulting in a whole process of negotiation. This paper employs techniques from the domains of multiple criteria decision making (MCDM) and group decision to deal with change negotiation in process collaborations. In particular, it utilizes multi-criteria reasoning to model...
Research has emerged over the past decade showing gender biases in software. Although a few methods and prototype systems have emerged to help address this issue, none have been reported to have an impact on the people who actually build software. In this paper, we summarize a few highlights from a year-long field study investigating how Gender HCI methods to address gender biases in software can...
During the last years, many companies established fast IT or digital IT units dedicated to build and operate digital customer-facing services. These units adopted agile methods, new tool chains as well as new organizational settings like BizDevOps teams. BizDevOps teams are responsible for continuously (re-)defining business functionality of certain (micro-)services, (re-)developing and running them...
This paper presents a multicriteria nominal classification method derived from the concepts of PROMETHEE, which is then applied to problems characterized by minimum performance profiles (MMP) to determine categories. In order to illustrate the applicability of the proposal, this method is applied to classify relational attitudes in the context of IT outsourcing regarding an IT service contractor company...
The authors have held both academic and industrial research positions, and have designed and carried out many empirical studies of large software systems that were built and maintained in industrial environments. Their experiences show that the most crucial component of a successful study is the participation of at least one industrial collaborator who is committed to the study's goals and is able...
In the present day, developed economies that function on the basis of knowledge indicate better economic performance. Many studies have shown that one prerequisite for economic growth is the availability of information and new findings – when the conditions of creativity and high technology are also present (not only for companies but also for regions and entire economies). Economic players face ever...
Task allocations in collaboration are complex. This paper presents a challenging assignment problem, called Group Role Assignment with Agents' Busyness Degrees (GRAABD). The solution to this problem aims at creating a high-performance group by role assignment with consideration of the busyness degrees of agents. The contribution of this paper is the formalization of the proposed problem, a practical...
The design of a printed circuit board (PCB) is an example of the variety of technologies that have to be combined in a single physical output. Thus the need for collaboration between engineering teams, each of which with their own expertise (e.g. electrical, mechanical, testing and manufacturing) is of paramount importance. This imposes the need to share the electrical design and the PCB layout among...
The advent of the internet of things and industry 4.0 bring new paradigms that tend to affect the way of organizing several human activities, among them the production processes that are ruled by production and human work on a large scale in the production lines. Therefore, it is inevitable to think of how to prepare students for this new, oncoming reality, since these students will have to deal with...
Rapid transformation of technologies and markets challenge organizations to build structures and norms that promote learning and innovation. Up until now, however, knowledge management has not been a common subject for investigation of university-industry collaboration in innovation projects. The few known studies have concentrated on the numbers of patents, spillovers and publications, or institutional...
According to the textbook [23], Scrum exists only in its entirety, where every component is essential to Scrum's success. However, in many organizational environments some of the components are omitted or modified in a way that is not aligned with the Scrum guidelines. Usually, such deviations result in missing the full benefits of Scrum [24]. Thereby, a Scrum process should be frequently inspected...
Goal understanding and communication of requirements are vital for ensuring that large and complex project organizations collaborate efficiently. We have used a design science approach to explore and address the problem of communication for large IT projects. We designed a method for avoiding communication gaps by eliciting information regarding stakeholders and information flows. The MAPS (Mapping...
The relevance of Requirements Engineering (RE) research to practitioners is a prerequisite for problem-driven research in the area and key for a long-term dissemination of research results to everyday practice. To understand better how industry practitioners perceive the practical relevance of RE research, we have initiated the RE-Pract project, an international collaboration conducting an empirical...
This paper presents first results of a project aiming to provide the requirements for enabling elderly people to stay longer in their flats or houses before moving to senior citizen's residences or nursing homes. Using market available devices an Ambient Assisted Living (AAL) system is developed for recording vital sign data. A minimal invasive radio transmission system and smart home sensors are...
Entrepreneurship has been linked with improved economic stability and the economic turnaround of countries. Creating and enabling environments that spur, cultivate and sustain entrepreneurs is of paramount importance. The purpose of this paper is to relate how entrepreneurial firms utilise external actors to create value in their companies in an entrepreneurial ecosystem. Of particular importance...
In the present paper the issue of horizontal cooperation in a road transportation network is tackled. Different road trips belonging to a set of carriers that form a coalition are shared, with the final goal of maximizing the carriers' profit. The higher the number of carriers belonging to the coalition, the greater the possibility of obtaining profitable trip combinations; however, this makes also...
Selection of study program plays an important role in the success of a person to determine his future. One of the risks associated with the selection of study is the incompatibility with the needs of the current job vacancies in companies that significantly affect the future of these students. Since there are many criteria that must be considered, then through this recommender system, students are...
Our trust always changes due to various conditions. We call it dynamics of trust. Researching about the change of trust is a necessary task because it could be applied into diverse applications such as trust-based recommendation systems. In this paper, our target is to i) propose a general definition of trust, ii) define temporal and spatial patterns for representing how trust changes. They can be...
