The core of the service is personalization, and personalized should be preceded by an understanding the individual, and the context surrounding the individual. People with disabilities want to use products, and have more services that are just right for him/her. However, since the developer of the product or service is often not the disabled, it is difficult to give insight into the problems of individuals with disabilities. Also, there is a lack of processes and framework in the development of products and services for the disability. Therefore, this paper will propose a framework for service design for people with disability according to Context-Based Activity modelling (CBAM), Product Service System (PSS) methodology, and International Classification of Functioning, Disability, and Health (ICF) framework. Then the specific process of the kneeling bus for people with disability is explained using the proposed service design framework for people with disability. We hope that this framework for service design for people with disability will become available through much research.

Simulation of forming operations, particularly using the finite element method, is clearly dependent on the accuracy of the constitutive models. In the last years, several methodologies were developed to improve the accuracy of constitutive models through parameter identification and calibration methodologies. However, independently of the efficacy of the calibration methods, the accuracy of a constitutive model is always constrained to its predefined mathematical formulation. Today, artificial intelligence (AI), such as Machine-learning (ML) techniques, can be used to overpass these limitations. However, their use in the reproduction of material behaviour was not fully explored.

A growing interest is nowadays directed towards the numerical modelling and monitoring of the interlaminar damage evolution of composite laminates, but also to the numerical mathematical models and techniques for simulation of the interface delamination. modelling and investigation of the mechanical behaviour and fracture modes of the multi-layered composites is a complex issue, since other important parameters, such as fibre orientation angles, stacking sequences and configuration of the composite laminates are added to the anisotropic character of the composite materials. Different failure modes may occur on multi-layered composites, while the delamination type fracture may lead to a considerable decrease of the load carrying capacity of the composite structures. Interlaminar stresses, which occur in composite laminates as an effect of the presence of the free edges, have a major influence on the delamination onset and the delamination growth. The paper summarizes the numerical methods and the approaches considered in the simulation of the delamination growth of composite laminates. The obtained results are figured in terms of the opening displacement at the interface crack tip and stress distributions on the plies of the multi-layered composites.

Software development is a human- intensive effort, hence software project success heavily depends on performance of the members of its development team. A team member’s performance can be influenced by many factors, such as level of technical skill, motivation, stress level as well as team culture and organizational environment. Understanding the impact of these factors on software project outcome can lead to better project management and human resource management decisions, and as a result improve project success rate. However, it is a non-trivial task to evaluate such impact, due to difficulties in quantifying humanbehaviour in a complex environment such as that of software project, hence little literature exists on this research topic. This study attempts to explore the impact of individual and team performance on software project outcome with a simulation model that introduces human factors to a virtual software project environment. The simulation model includes the interplay of three aspects typical of a software project environment, namely: a) individual behaviour of each developer and communication among team members;b) software development workflow of activities and project management practices;and c) organizational environment including culture and HR practices. A hybrid model that includes the application of agent-based, system dynamics and discrete event approaches has been developed. Agent-based modelling (ABM) is one of the most suitable techniques for investigating the complexity of agents’ behaviour, actions, and interactions, thus allows us to observe the emergent behaviour of each individual agent;system dynamics (SD) modelling is suitable for observing, at an aggregated level, the cumulative and dynamic effect of varying conditions that influence the behaviours of model components;and discrete event simulation (DES) is suitable for capturing work flow under resource and/or other constraints. In our hybrid model, the agent-based component is develo

This paper illustrates the modelling and simulation (M&S) based engineering approach developed in the framework of ITEA2 project MODRIO to the case of a Backup Power Supply. This system integrates physical and human aspects with computer-based controls, and is therefore a so-called socio-cyberphysical systems (SCPS). This system is relatively simple in terms of physics but is a realistic example of a reactive hybrid system, illustrating the modelling of control logic and timing issues, and the use of discrete time domains. The MODRIO approach is presented in more details in [8].

Many data mining approaches aim at modelling and predicting humanbehaviour. An important quantity of interest is the quality of model-based predictions, e.g. for comparative analysis and finding a competition winner with best prediction performance. In real life, human beings meet their decisions with considerable uncertainty. Its assessment and resulting implications for the statistically evident evaluation of predictive models are in the main focus of this contribution. We identify relevant sources of uncertainty as well as the limited ability of its accurate measurement, propose an uncertainty-aware methodology for more evident evaluations of data mining approaches, and discuss its implications for existing quality assessment strategies. Specifically, our approach switches from common point-paradigm to more appropriate distribution-paradigm. The proposed methodology is exemplified in the context of recommender systems and their established metrics of prediction quality. The discussion is substantiated by comprehensive experiments with real users and large-scale simulations.

Finite element modelling and analysis is an alternative way to study human fracture behaviour in biomechanics field compared to experimental test in laboratory. The aim of this study is to analyse the stress intensity factor (K) and strain energy release rate (J-integral) when three-point bending test and tensile test are applied on a two-dimensional (2D) cortical bone model developed by using finite element software with different applied loads and crack-to-width ratios. Two methods are used to to evaluate the values of K and J-integral which are Displacement Extrapolation Method (DEM) and CINT method. The values then been compared with other theoretical expression done by other researchers for validation purposes. It has been proved that by using CINT method, the error is very small compared to DEM method. As a result, stress intensity factor values increased as crack-to-width ratio increased and strain energy release rate also increased as crack-to-width ratio and loads increased. It can be concluded that finite element analysis can be used to study the fracture behaviour of human cortical bone. Therefore, researchers can easily study the behaviour of cortical bone using simulation instead of mechanical experiment.
