Operator Workload

This paper presents the methodology and supporting rationale for the investigation of operator workload in the context of an enhancement to an existing weapon system. The methodology is applicable early in the conceptual design process and forms the baseline data from which final design validation may be developed. The Subjective Workload Assessment Technique (SWAT), used projectively, forms the kernel of the methodology. A strategy for building part-task through full-mission simulations, at increasing levels of face and content validity, is presented in the context of the weapon system development process.

Equipment Performance

The MANPRINT (Manpower and Personnel Integration) Program is a comprehensive program designed to enhance human performance and reliability during weapon system development with the overall goal – of optimizing total system performance. Total system performance is a function of equipment performance and human performance as they are affected under varying environmental conditions which includes physical, social and operational conditions. The challenge the U.S. Army has today is to ensure these issues are addressed early in and continuously throughout the design process.

Operator Workload

The objective was to structure the concept of workload in a practical way which would permit Human Factors Systems Engineers to apply this concept to various phases of the development process. Workload is a qualitative rather than absolute concept which, like motivation, is inferred to exist by measuring the relative behavioral reactions to certain conditions. Workload may be thought of as an intervening variable between physical, mental, visual, vocal, or auditory antecedent conditions, and whatever performance-based, subjective or physiological measures that may be sensitive enough to reflect changes in the antecedent conditions. The practical approach has been to consider workload as the number of things to do modified by the level of difficulty. This concept has successfully permitted HF Systems Engineers to assess operator workload at progressive levels of system development.

A freezing chucker is a clamp-less mechanism of fixture for easy broken egg-shell, clay, and other ferrous/nonferrous materials. Typical structure of this mechanism includes a top plate for freezing workpieces, a body with specially designed channels for the coolant flows, and a bottom plate to fasten on the table of other machine. Just by a small amount of liquids on the top surface and by rapidly cool down to 253K, parts can be frozen stationary on the top plate surface and can conduct precision machining on it. There are four steps to design a new freeze chucker by the engineering design process: planning and clarifying the task; conceptual design; embodiment design; detailed design. Some useful tools from the Quality Function Deployment (QFD) technique and the Theory of Inventive Problem Solving (TRIZ) method are used in this design process. Eight concept designs are generated by the conceptual design work and the final design of channel with transverse ribs is selected by decision matrix technique during embodiment design and detailed design stage. This final design is evaluated by numerical modeling of the COMSOL MULTIPHYSICS 3.2 finite-element based package. Performances such as the temperature distribution of top-plate surface temperature and the lowest temperature of a freezing chucker are shown. Numerical results show the success of the innovative channel design by this inventive design process using TRIZ methodology.

Chassis jig is needed to ensure that the welded chassis components does not warp or deform during welding process. Through concept screening and concept scoring, multiple design of chassis jigs is narrowed down to next development process. This study aims to design a chassis jig for the fabrication of student car competition chassis. The desired result of this design process is chassis jig with the ability to manufacture a wide variety of student competition car chassis.

Abstract This paper is to present the chosen methodology for research and thus approach the design process through biomimicry. The described methodology is applied in parasitic architecture research, focusing on developing the experimental design of architectural structure using artificial intelligence and thus approach and support the central hypothesis of the work -the effort to create self-designing and self-growing / developing architecture. Furthermore, the paper outlines the ontology as a model of knowledge, a source of data for the developed software © PAF A.I. and a source of inspiration influencing the final design of the proposed architectural structure. The way in which such an ontological resource is processed for research purposes and how it participates in the final design within the verification and validation of the whole conceptual design is also described. Besides, the paper explains why the ontology in question is essential and what was established as its content.

This paper presents an overview of existing function-based conceptual design expert (CDE) systems with a view to identifying their scope in the contexts of functional modeling knowledge representation and conceptual design process. A number of heterogeneous function-based CDE systems are identified and listed. A key comprehensive benchmarking framework is developed in this paper that helps in identifying the trend, gaps and scope of current function-based CDE systems. Accordingly, the gaps in the aforementioned contexts are discussed which are to date have not been summarized and highlighted for a well-balanced system development for a product conceptual design.

Abstract Novel practices in the formation of students are encouraged to be multidisciplinary which in fact, allows them to better understand the behaviour of systems. This skill allows them to identify existing needs that impact multiple areas, both for an organization and to complement their entrepreneurial training. In this work, there is exposed a reference framework that arose to aid in the innovative design process among the manufacturing sector, it seeks to stretch the gap between conceptualization and implementation for engineering projects. Furthermore, the formation of the learners is enriched due to the breakdown of complex systems into entities as it gathers existing knowledge and provides structure to systematize the development process, allocate problems and provide feedback. Thus, design stages are detailed, engineering stages are described, and a toolbox is presented to guide designers into their task. The methodology has been tested under multidisciplinary projects in different time lapses, observing a positive impact in the formation of participants, as it guarantees the inclusion of desired attributes, documentation and milestones in the scenario being developed. In this article, there are described three case studies. Findings when developing using the methodology shows a structural, documented process followed by the designers, capable of recognizing the abilities acquired and reinforced skills, documented entities corresponding to what is developed at the end of the projects and time of deployment is enhanced.

An accurate understanding of users' needs is essential for the development of innovative products. This article presents an exploratory method of user centered research in the context of the design process of technological products, conceived from the demands of a large information technology company. The method is oriented - but not restricted - to the initial stages of the product development process, and uses low-resolution prototypes and simulations of interactions, allowing users to imagine themselves in a future context through fictitious environments and scenarios in the ambit of ideation. The method is effective in identifying the requirements of the experience related to the product’s usage and allows rapid iteration on existing assumptions and greater exploration of design concepts that emerge throughout the investigation.
