Demand of the international electricity engineering contracting is not only influenced by the factors from the internal of the electricity system, but the factors about electricity planning, macroeconomic, new energy development and so on. To distinguish the interaction and interrelationship between them, Interpretive Structural Modeling (ISM) methodology is used to identify the interrelationship...
The impact of efficient Information System Strategy Plans has proven crucial to modern-day corporations. However, during the analysis phase for a technical solution to fulfil an identified need in an enterprise, many teams tend to focus on a very issue-specific analysis and overlook its underlying global corporate impacts. On the other hand, it is difficult and time-expensive for these teams to analyse...
In the last decades power systems witnessed the implementation of an organizational and operational restructuring that lead to the introduction of competitive mechanisms in some activities of the value chain. This is the case of generation and retailing with the development of wholesale and retail markets. These developments together with a renewed emphasis on the adoption of more sustainable solutions...
As part of a larger research project, this study addresses issues of risk-based decision-making based on different decision-makers in carbon resource planning for manufacturers under the constraints of C&T, we specify their characterization of behavior, attitude to the C&T program, and design their rule-based expert system (RBS) respectively. we develop discrete-event simulation models for...
A recent proliferation of UAVs accompanies several critical issues to be considered for efficient, secure use of UAVs. One of those issues should be a privacy of people. Also, when the UAVs fly to perform specific objectives, minimizing movements of UAVs is a big issue to provide a minimum mission completion time and a maximum network lifetime. One intuitive solution is that UAVs may pass through...
Large software development organizations adopting agile methods need solutions and models to help scale agile to fit their needs. During recent years, several frameworks for scaling agile have been created by consultants, including the Scaled Agile Framework (SAFe), Large-scale Scrum (LeSS) and Disciplined Agile Delivery (DAD). However, research on how these frameworks are adopted in practice is seriously...
The choice of the most efficient modernization strategy for an industrial enterprise is made according to the economic model of financial and investment planning given the comparison of key indicators of financial and economic activity. During the study, the analysis of financial and economic activities over the years 2015 and 2016 was carried out and the forecast of indicators for the period 2018–2021...
Nowadays, complex systems represent research topics to a variety of sciences and professional practice methods. In the social sciences field, the main objective of the complexity studies would be to explain the interactions between the members of a social system (economic, etc.). To conduct the internal audit activity in terms of economy, efficiency and effectiveness requires a functional structure...
In urban goods delivery, the service quality is affected by number of lorry, distance between two points, road blocking and assigned time of customers, etc. The lower efficiency of human power and delivery time are caused from poor route planning. A hybrid approach of route finding, which is involved in multi-objectives and lorry assignment, is developed for achieving the optimal delivery schedule...
Facing the increasing pressure in road transportation, small and medium-sized carriers are trying to establish horizontal coalition to reduce operational costs and improve their profitability. In this paper, the multi-type products Collaborative Vehicle Routing Problem with Transshipment (CoVRPT) is proposed. A mixed-integer linear programming model for this problem is established. The result of this...
A Massive Open Online Course (MOOC) is a popular way for universities to deliver quality course content to a global audience. Furthermore, a MOOC specialization offers a series of related such courses with a capstone component. Typical software engineering capstone projects in campus courses involve teamwork and creating software. Within such a context, students experience the software development...
Due to the fact that software development is a product of team effort it is important to investigate the influence of group developmental psychology on software development performance. In this case study we wanted to test how performance (i.e. velocity and planning effectiveness) are related to the group's maturity level. We gave the Group Development Questionnaire (the GDQ) to 19 software developers...
Continuous Planning (CP) is a management practice inspired in principles from the agile and lean software development. In this paper, we present in detail the case of a small Brazilian software company on moving from an agile background towards CP, due to a constant changing environment. Furthermore, we discuss the reported case in the light of the technical literature on CP. Although observing evidence...
Context: Open Source is getting more and more collaborative with industry. At the same time, modeling is today playing a crucial role in development of, e.g., safety critical software. Goal: However, there is a lack of research about the use of modeling in Open Source. Our goal is to shed some light into the motivation and benefits of the use of modeling and its use within project teams. Method: In...
Our research studies the harvest plan for aromatic coconut for the aromatic coconut manufacturers located in Ratchaburi province, Thailand. The supply planning is complex because there are many uncertain factors. For example, the number of coconuts in each crop is varied and depends on the season, water amount, soil fertility and pests. In addition, coconut price at farm gate is highly fluctuated...
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...
The comprehension of human mobility patterns can help governments and private sectors to improve the quality of services offered to population. Characterizing and understanding the different workloads generated on mobile networks during different kind of events are a challenge for carriers, who should keep connectivity services always on. The visualization and analysis of such workloads can drive...
In communication networks such as ISPs, telcos, and mobile network operators (MNOs), determining a correct unit cost for a service with QoS is a crucial task for the future of companies. A well-defined and efficient cost model is an essential tool to analyze network dynamics and in decision-making processes in a network. Also, knowing the real unit cost for a service helps network administrators/operators...
One of the considerations that must be evaluated when performing a facility wide shut down for maintenance is an outline of the utility's scope of work. It is not as simple as coordinating the shutdown date and time but also requires identification of the utility inclusions and exclusions in the scope of work. Without proper identification, it leaves a lot of unknowns during the power restoration...
Effort estimation is more challenging in an agile context, as instead of exerting strict control over changes in requirements, dynamism is embraced. Current practice relies on expert judgment, where the accuracy of estimates is sensitive to the expertise of practitioners and prone to bias. In order to improve the effectiveness of the effort estimation process, the goal of this research is to investigate...
