APPLICATIONS OF ENVIRONMENT-BASED DESIGN (EBD) METHODOLOGY

A product’s environments play a significant role in its development. In other words, any alteration in the environment surrounding a product leads to changes in its features. Hence, having a systematic procedure to analyze the product’s environments is a crucial need for industries. Environment-Based Design (EBD) methodology describes the environment of the product (excluding the product itself) and presents a rational approach to analyze it. In order to achieve an efficient product design and development process, EBD utilizes different tools. Recursive Object Model (ROM) diagram, Cause and Effect Analysis, Life Cycle Analysis, Asking Right Question and Answering are EBD’s major tools and technics. In this research, we aim to represent EBD’s capabilities for product evolution analysis, complex products development and human-centered products development. In order to demonstrate EBD’s competences for product evolution analysis, we conduct a case study of braking systems evolution analysis through analyzing the environments around them. Afterward, we perform environment analysis for aerospace design methodology in order to propose a novel design methodology for the aerospace industries. Finally, we propose a course scheduling model based on environment analysis of the academic schedules and we verify our model using Concordia University’s courses

According to Piaget's theory of cognitive development, these representations develop during the sensorimotor stage and the pre-operational stage. We propose a model that relates the conceptualization of the higher-level information from visual stimuli to the development of ventral/dorsal visual streams. This model employs neural network architecture incorporating a predictive sensory module based on an RNNPB (Recurrent Neural Network with Parametric Biases) and a horizontal product model. We exemplify this model through a robot passively observing an object to learn its features and movements. During the learning process of observing sensorimotor primitives, i.e., observing a set of trajectories of arm movements and its oriented object features, the pre-symbolic representation is self-organized in the parametric units. These representational units act as bifurcation parameters, guiding the robot to recognize and predict various learned sensorimotor primitives. The pre-symbolic representation also accounts for the learning of sensorimotor primitives in a latent learning context.Peer reviewedFinal Published versio

Capture Knowledge with Object-Process Modeling - a systems engineering approach

To increase the efficiency of the product development process at Volvo Car Group, knowledge accumulation is central in the early strategy and concept phase. Within the department for Research and Development, the unit responsible for powertrain engineering desires a process to document system interfaces, in order to reuse what they do already know in new applications. This thesis presents a process how to capture systems knowledge; i.e. interactions within system structure, functions and behavior with the use of object-process oriented modeling. Included in the process is also ideas presented how to manage and maintain as well as interpret and reuse captured knowledge. During the first part of the project, literature of theory and previous empiric was explored, in order to understand principles of knowledge based development and systems engineering. To identify needs of the desired process, system engineers responsible for the complete powertrain were interviewed. Thereafter, the interpreted needs were translated to a functional analysis of the desired process. A case study was conducted at different developing units across Powertrain Engineering. The purpose was to map system knowledge with object-process methodology. The result was a mapped system architecture based on the vehicle response attribute, where captured system knowledge is connected to the development phases as well as the system responsible. The object-process oriented model of the system architecture included qualitative traceability between system requirements, decomposed functions, product structure with physical interface as well as resources defining who is owner of the system knowledge. To illustrate how to interpret and make the captured system knowledge reusable, structural relations within three systems was mapped in a domain mapping matrix, which is a matrix mapping the dependencies between two data types. In this case requirements and functions, as well as functions and hardware components

A Metrics-based Framework for Estimating the Maintainability of Object-Oriented Software

Time,  effort  and  money  required  in  maintaining software has always  been  considered  greater  than  its  development  time. Also, its ambiguity in forecast at early stage of software development makes the process more complicated. The early estimation of maintainability will significantly help software designers to adjust the software product, if there is any fault, in early stages of designing. By doing this; time, effort and money required in maintaining software will be lessened. Although Object Oriented Software Development (OOSD) approach is equipped for enhancing software maintainability, a method for finding out if the required level of maintenance is being achieved amid the development process is required. This can be accomplished through measurement. This paper outlines the need and importance of maintainability at design phase and develops a Metrics-Based Maintainability Estimation Framework for Object-Oriented software(MEFOOS) that estimates the maintainability of object oriented software components in regard of their Understandability, Modifiability and Portability—which are the sub-attributes of maintainability.

Functional modelling using an object-oriented design system

A significant progress in the development of CAD-systems was the extension to functionalities handling more than pure geometry (such as points, edges, surfaces and bodies), i.e. data concerning the technical product structure (such as physical and mechanical properties). These efforts are made to accelerate the engineering and design process, to avoid errors during the engineering process and to make use of the product-related data in electronic form in the later phases of the product life cycle. One approach to extend the CAD-functionalities is feature-based design, which aims at representing some apects of the product separately. Yet it is necessary to include the different kinds of features (describing different properties of the product) into a complete model. Despite the efforts of the institutes of standardization a satisfying product model has not yet been defined. A possible solution of this problem may be the definition of a meta-language for the engineer allowing him to build his own product model including his own characteristical entities of the product. This meta-language must be very simple to understand and to extend; the derived sentences (the instances of his product model) must be exchangable and combinable. The object-oriented concept and the different components (terminals or alphabet, non-terminals or symbols and deriving rules) of this meta-language are discussed in this paper

Application feature model for geometrical specification of assemblies

The work begins with the description of a Domain Meta-Model for collaborative and integrated product development based on a Feature Model that aggregates all Application Features required to support domain specific reasoning. These Application Features are conceived as an aggregation of several Object Features containing all the knowledge about the structure and geometric interface that are the solution for a certain function. Afterwards, the Specification Feature, as a specialisation of the previous feature, is presented. This contains information about geometry, nominal and with defects, as well as about the relations established between them in the dimensional and geometrical specification process of an assembly, as established by GPS standard. Finally, the Specification Assembly Model is shown, an assembly model based on the Specification Feature and on the description of specifications using the Geospelling language
