The increasing amount of gathered sensor data in Industry 4.0 allows comprehensive data analysis software that creates value-adding opportunities. As companies often cannot implement such software by themselves and as they typically don't want to give their data to external scientists, they commission them to build the required software in order to execute it locally. However, installing, configuring,...
The development process of complex production machines requires an intense collaboration of different technical disciplines. In this context, the interdisciplinary development team often lacks a common and continuously updated system model of the machine, which can consequently lead to high communication effort and delays the overall development process. For a more efficient and effective production...
This paper investigates how renewable resources can be exploited to overcome the power shortage and produce a significant amount of the energy demand from the most feasible renewable sources in Bangladesh. Using two energy system analysis softwares, HOMER which specializes in optimizing energy systems and EnergyPLAN which focuses on larger regions, a strong smart city model has been presented which...
In this paper, the trailing suction hopper dredger dredging production is used to be an optimization objective. By analyzing the impacts of dredging operation behaviors and system uptime factors, an artificial neural network algorithm for parameter optimization of dredging operations is proposed. Based on the field construction parameters of the trailing suction hopper dredger, the method integrates...
This article employed modeling analysis of flower production process with Petri Net, which based on the analysis of production logistics system of flower production enterprises, using Witness simulation software to study the flower production process at the same time. The article found some existing problems of the flower production logistics system through the simulation, and put forward several...
An Agent-based Computational Economics Model based on Classical Economics, the ACE-CE model for short, is established through a combined approach of the theoretical method and computational method. This model has successfully conducted several applications in China, which has proven the feasibility of mixed methods for large-scale computation in economics. It also verifies the theoretical rationality...
Implementation of the sustainable policy guidelines at a company level is not an easy task. The decisions about resource allocation, changes in process organization or new investments should be considered taking into account their economic, environmental and social effects. Remanufacturing processes contributes to the fulfilment of the circular economy paradigm. The existing body of literature highlights...
Large cluster systems are composed of complex, interacting hardware and software components. Components, or the interactions between components, may fail due to many different reasons, leading to the eventual failure of executing jobs. This paper investigates an open question about failure diagnosis: What are the characteristics of the errors that lead to cluster system failures? To this end, this...
Nowadays Learning Games are widely utilized in various domains to ease learning and capture the focus of learner using playful spring. Although many researchers show that using Learning Games increase motivation and interest. However Learning Games users still suffer from the high cost and difficulties of developing and designing an attractive learning game without being a designer or an informatics...
Model-based software development has become a mainstream approach for efficiently producing designs, test suites and program code. In this context, model-to-model transformations have become first-class entities and their classification, formalization and implementation are the subject of ongoing research. This work surveys the characteristics and properties of graph rewriting systems and their application...
Production environments in large enterprises are expensive to maintain, support and enhance. Organisations take extreme care to provision and configure their environments and they are very wary to change. This is because a small change may result to a domino effect of failures resulting in costly system downtime. Consequently, engineers are also looking for reliable ways of testing environmental changes...
A key success factor for building smart control software for today's energy systems is a precise understanding of their behavioral requirements. However, current engineering approaches lack the possibility to validate these requirements in early phases of development. The validation is hampered by the difficulty estimating the impact of requirements on the overall system behavior before a complete...
This paper outlines the application of a special Environmental Management Information System (EMIS) that combines discrete event simulation (DES) and life cycle analysis (LCA) in addition to material flow analysis as an integrated part of the simulation software. The motivation behind the combination of these different techniques is to close the gap between identifying only parts of the life cycle,...
As an implement process of a series of highly complex systems, the construction of enterprise informatization requires enormous human, financial and material resources. In order to solve the problem that it is difficult to quantitatively identify the contribution of huge input to the enterprise, with grid enterprises as background, this article analyzes the informatization investment's factors and...
Software reuse aims to eliminate repetitive system development efforts, and improve the quality of software by using proven solutions to business analysis, system design and implementation. This paper proposes the combined use of multiple modelling languages to support the reuse of engineering artifacts at different abstraction levels. In particular, an agent-oriented requirement modelling language,...
Software product quality and project productivity require defining suitable software process models. The best process depends on the circumstances where it is applied. Typically, a process engineer tailors a specific process for each project or each project type from an organizational software process model. Frequently, tailoring is performed in an informal and reactive fashion, which is expensive,...

According to the need of industrial and agricultural production and living, we introduce “scatter sequence” of a regular triangle and build an optimization design model to maximize the minimum scatter numbers. Based on LINGO software, we obtain the solution of the minimum scatter numbers and their coordinates in some “scatter sequences” of the regular triangles with different numbers of points and...
Many physical and information goods are not "consumed" during use e.g. airplanes and computer software. These 'durable goods' have been extensively studied over the last four decades in the economics, operations, information systems, and other literatures. Due to the heterogeneous nature of durable goods and their market contexts, the recommendations from the 'durable goods' literature cannot...
