2. Human Behavior Modeling: A Challenge for Simulation enabling a Brave New World of Applications.

Agostino G. Bruzzone, Genoa University, Italy.

Abstract: Simulation addresses many application fields. Today complex systems are most promising sectors for M&S considering that to model and to simulate them is often the only suitable approach for investigation. Indeed many complex systems are involving humans as key elements. Sustainability, environment, disasters, defense, industry, supply chain management are just examples where the real systems are strongly dependent on people behaviors. In some case the elements of the system deal with few individuals and their decisions, in some other case large social networks are driving events and actions; in both case M&S needs to address these elements reproducing both rational, emotional, individual and social behaviors related to human beings.

Being able to create human behavior models it becomes possible to carry out experimental analysis and studies otherwise almost impossible; obviously this sector represent a big challenge for M&S community even considering the complexity to model and to validate the HBM (Human Behavior Models).

The presentation addresses methodologies to apply simulation to HBM, guidelines to define the models as well as architectures for properly develop, integrate and test these simulators.

Indeed a major issue in this aspect is the capability to interoperate the HBM with other models in order to support simulation of complex systems. Along these years several interesting researches has been carried out in this sector and the presentation will include models addressing these aspects in different fields including: Natural Disasters, Man-Made Accidents, Transportations, Retail, Food Contamination, Country Reconstruction, Decision Making.

5. Model Engineering for Complex Systems Simulation

Lin Zhang, Beihang University, P. R. China

Abstract: A complex system is a system with the distinction that its parts and relationships are gathered together under the forces of components and emergence. Generally a model experiences requirement analysis, model design, model construction, model verification and validation (VV&A), model application and model maintenance. These processes compose a complete lifecycle of a model. There much research on certain phase of the model lifecycle for specific domains. But there lacks of generic domain-free methodology to deal with the whole lifecycle of a model of a complex system. Model Engineering (ME) aims at setting up a systematic, standardized, and quantifiable engineering methodology to manage the data, knowledge, activities, processes and organizations/people involved in the full life cycle of the model, in order to obtain the general term of credible model theory, methods, technology, standards and tools with the minimum cost. This lecture will discuss the hard challenges involved in the model lifecycle of a complex system, such as the high complexity and long life cycle of a complex system model, the complex evolution process of a model, the model reuse problem, the huge amount of data, the multidisciplinary collaboration in model development and management, etc. The challenges on developing a complete theory and technology system and philosophy of model engineering and main research topics in model engineering as a sub- discipline of M&S will also be discussed.

6. Software Decay as a Big-Data Problem Viewed Through the Architectural Lens

Nenad Medvidović, Computer Science Department at the University of Southern California, USA.

Abstract: Engineers frequently neglect to carefully consider the impact of their changes to a software system. As a result, the software system's architecture eventually deviates from the original designers' intent and degrades through unplanned introduction of new and/or invalidation of existing design decisions. Architectural decay increases the cost of making subsequent modifications and decreases a system's dependability, until engineers are no longer able to effectively evolve the system. At that point, the system's actual architecture may have to be recovered from the implementation artifacts, but this is a time-consuming and error-prone process, and leaves critical issues unresolved: the problems caused by architectural decay will likely be obfuscated by the system's many elements and their interrelationships, thus risking further decay. In this talk I will focus on pinpointing the locations in a software system's architecture that reflect architectural decay, the points in time when that decay tends to occur, and the reasons why that decay occurs. Specifically, I will present an emerging catalogue of commonly occurring symptoms of decay - architectural "smells". I will illustrate the occurrence of smells identified in the process of recovering the architectures of many versions belonging a large number of real-world systems. I will also discuss the relationship between architectural smells and the much better understood code smells. Finally, I will discuss several undesirable but common occurrences during the evolution of existing systems that directly contribute to decay. I will conclude by identifying a number of simple steps that engineers can undertake to stem software system decay.
