Based on study of risk assessment models on domestic and foreign countries' software projects, this paper adopted Fuzzy Analytic Hierarchy Process to establish the risk assessment model for software projects, so as to realize the effective risk assessment on software projects.
Using IDE usage data to analyze the behavior of software developers in the field, during the course of their daily work, can lend support to (or dispute) laboratory studies of devel- opers. This paper describes a technique that leverages Hidden Markov Models (HMMs) as a means of mining high-level developer behavior from low-level IDE interaction traces of many developers in the field. HMMs use dual...
Natural or man-made disasters often result in trapped victims under rubble piles. In such emergency response situations, Urban Search and Rescue (USaR) teams have to make quick decisions to determine the location of possible trapped humans. The fast 3D modelling of collapsed buildings using images from Unmanned Aerial Vehicles (UAVs) can significantly help the USaR operations and improve disaster...
The Traditional Malay Houses (TMH) in Malaysia are considered as vernacular architecture, built and designed by the locals with thoughtful considerations and appreciation for nature. There are various beneficial features in technical and environmental contexts of a TMH that should be investigated further and applied in the present-day built environment. Due to its modularity and ingenious construction...
This papers content is about evaluating how to utilise hybridisation of digital communications in order to secure sustainable approaches based on green buildings and infrastructure. The challenges associated with environmental and social impacts of building designs have created socio-economic impacts on our communities. There is an extensive push for “technical optimism” while engaging the communities...
Scenario-based approaches are often used for Software Requirements Specification (SRS). Since scenarios are usually written in natural language, they may be ambiguous and, sometimes, inaccurate, which impair requirements quality. One of the major factors for this problem is because interactions among scenarios are seldom represented explicitly. As such, the importance of correctness, consistency and...
The paper presents an ongoing research within a multidisciplinary collaboration aiming at improving information and tools to prepare local authorities, volunteers and citizens (at a municipal and/or inter-municipal level) to anticipate, cope with, resist against and recover from the impacts of hydro-geological hazards. In particular, the paper aims at presenting the general framework and first results...
Code-generation environments have emerged as a new mechanism for building software systems in a systematic manner. At their core, model-driven engineering technologies such as model-to-model and model-to-text transformations are effectively used to build generation engines. However, due to the complexity of model-to-model and model-to-text transformation scripts, which is exacerbated as they are composed...
Software product line engineering (SPLE) is a software development approach that attempts to maximize reusability. In the domain engineering phase, managing variability poses a great challenge to developers because traditional techniques of software engineering are not applicable in handling variability. In this paper, we apply the Product Family Modeling Language (PFML) approach and the Orthogonal...
For the regression system composed of the two linear regression equations, we propose three kinds of relative efficiencies of the covariance improvement on the unknown parameter vector toward the best linear unbiased estimate, the lower bounds of which are respectively given in the paper. Then the three kinds of efficiencies are compared by numerical simulation so that the best are found.
On-Functional Requirements (NFRs) are vital for the success of software systems. Generally speaking, NFRs are some implicit expectations about how well the software will work, often known as software quality. For building better software, the NFRs should be considered as criteria for design decision. However, different NFRs may produce different criteria on the implementation strategies of the software...
Studying human analyst's behavior in automated tracing is a new research thrust. Building on a growing body of work in this area, we offer a novel approach to understanding requirements analyst's information seeking and gathering. We model analysts as predators in pursuit of prey — the relevant traceability information, and leverage the optimality models to characterize a rational decision process...
Based on the analysis of building energy efficiency features, considering the construction of energy efficiency factors, this paper AHP establish a comprehensive evaluation of building energy efficiency design model based on grey theory. This model mainly combines quantitative analysis, qualitative and quantitative analysis methods to overcome the evaluation's the subjectivity and arbitrariness, and...
Supply Chain Simulation (SCS) is today a well-defined branch of discrete-event simulation applications. The differences between different applications are usually small, but in the case of SCS, models tend to be larger, take longer time to build and are harder to validate. To remedy some of these issues in SCS, we propose to use the SCOR model (Supply Chain Operations Reference Model) as a tool to...
When problems are extremely complex, highly variable and too big for simple calculations, a simulation project solution should be considered. Not surprisingly, the resulting project endeavor will also be complex and should be managed with a clear strategy and attention to detail. This paper will extend beyond basic project tips by providing specific tools and methodologies to help simulation leaders...
In this paper, we proposed a method for developing Influence Diagrams by using the engine namely, Structural Modeling, Inference, and Learning Engine (SMILE). An influence diagram is a simple visual representation of a decision problem. It can be used to assist in rational decision making for different purposes. We proposed a practical method and a piece of source code in C#.net to build an influence...
This paper reports on an empirical study that explores the model development process followed by six expert modelers in discrete-event simulation (DES). So far the model development practice in DES has not been explored and there is little understanding of the processes followed. This study observes the modeling process of practitioners, experts in simulation modeling undertaking a laboratory modeling...
For more than half a century, simulation has proven to be a successful companion to decision makers and analysts around the world, with several packages being successfully used by thousands of modelers, our team being one of them. Despite great popularity and success, however, there have been issues and short-comings that may threaten the accuracy and efficiency of the model as a decision-making tool...

The space-time effect during soft clay soil areas deep foundation pit excavation is an objective reality. The time taking of excavation is an important index of foundation designment and construction parameters determination. In this paper, based on one station foundation pits of NO.2 subway in Wuhan city, the 2-D numerical simulation model which consider the excavation time-effect is established...
