Design and implementation of ergonomic risk assessment feedback system for improved work posture assessment

Ergonomic risk factors which include force, repetition and awkward postures, can result in Work-Related Musculoskeletal Disorders (WMSDs) among workers. Hence, systems that provide real-time feedback to the worker concerning his current ergonomic behaviours are desirable. This paper presents the design and implementation of a human-machine interface posture assessment feedback system whose conceptual model is developed through a model-driven development perspective using the Unified Modeling Language (UML) and interface flow diagrams. The resulting system provides a shop floor with a simple, cost-effective and automatic tool for real-time display of worker's postures. Testing the system on volunteer participants reveals that it is easy to use, achieves real-time posture assessment and provides easy-to-understand feedback to workers. This system may be useful for reducing the rate of occurrence of awkward postures, one of the contributing factors to risk of WMSDs among workers.

Multiagent-based modeling for re-entrant manufacturing system

Re-entrant flow manufacturing system is a typical mix of different process types, sequence-dependent setup times, very expensive equipment, and re-entrant flows. A multiagent-based modeling technology for re-entrant manufacturing system was addressed. The model of Agent-based Colored Timed Petri-Net (ACTPN) is constructed, which consists of the material flow net model and the interactive protocol model. In the material flow net, the interior behavior of machine agent was encapsulated and it was separated into the system layer, machine group layer and machine agent layer to form a hierarchical multiagent-based model, which reduced the complexity and improved the reusability of the model. In the view of modeling methodology of the interactive protocol net, the transforming rule from Agent Unified Modeling Language (AUML) to ACTPN was given so as to map the AUML model to ACTPN model. In the view of the analysis method of the interactive protocol net, it was integrated with a reachability graph to check the liveness and bound properties of interactive protocol model. A distributed discrete event simulation platform to evaluate the performance of the multiagent-based re-entrant manufacturing system was built. An illustrative example of a 6-inch semiconductor fabrication line in Shanghai demonstrates the effectiveness of the approach proposed.

Using Scrum and unified modelling language to analyze and design an automatic course scheduling system

This research used a case study methodology to examine large-scale software projects accomplished despite ambiguous customer requirements. This study adopted Scrum as the agile software development method and used unified modelling language (UML) diagrams to enhance design implementation documents and improve the software development process. This study presented how the case company explored a Scrum-based automatic course scheduling system for elementary and secondary schools. Through interviews, the case company incorporated customers’ requirements by using the corresponding UML diagrams, which helped the project team document the software development process and design the functions to satisfy customer demand. Then, the proposed method was introduced to the automatic elementary and secondary school course scheduling system project undertaken by the case company, verifying the feasibility of the proposed method. A few problems arose in the proposed software development process, and remedies were discussed. Software companies could use these results as a reference when implementing a large-scale software project with ambiguous customer requirements.

Classification of model transformation techniques used in UML-based Web engineering

Software development techniques are continuously evolving with the goal of solving the main problems that still affect the building and maintenance of software systems: time, costs and error-proneness. Model-driven engineering (MDE) approaches aim to reduce at least some of these problems providing techniques for the construction of models and the specification of transformation rules, tool support and automatic generation of code and documentation. The method of resolution of MDE is to first build models, which are independent of the platform, transforming them in later stages to technological-dependent models, and to achieve automatic model and code generation based on transformation rules. Web engineering is a domain where model-driven approaches can be used to address evolution and adaptation of Web software to continuously emerging new platforms and changes in technologies. We present an overview of the development process of the Unified Modelling Language (UML)-based Web engineering (UWE) defined as an MDE approach. The main characteristic of UWE is the use of standards including the UML, XML metadata interchange as model exchange, meta-object facility for metamodelling, model-driven architecture and the transformation language query-view-transformation. We focus on the model transformation aspects of the UWE process.
