  • Recently, consumers are tend to purchase the user-centered designed product using interface enginnering and human factors techniques. Therefore, it is important that the designer's requirements should be analyzed focused on the human machine interface. This paper described the interface usability evaluation technique(suvjective evaluation) for the interface between user and product. This methodology is the integrated interface usbility evaluation method AHP and Conjoint Analysis. AHP(Analytic Hierarchy Process) is a multicriteria decision model to give priority after expressing hierarchically for decision making problem. Conjoint Analysis enduavors to unravel the value, or partworths, that consumers place on the product or service's attributes from experimental subjects' evluation of profiles based on hypothetical products or services. A new usability test methodology proposed by this paper includes techniques jointed both consistency test by AHP and experimental subjective evaluation of profiles by Conjoint Analysis for evaluating the user's emotion and impression.

  • In this paper we deal with a design of the evaluation system to assess the vehicle operational control algorithm for Personal Rapid Transit(PRT) system. PRT system is different from the conventional rail traffic system in such that the station is off-line so as to guarantee a very short headway. In this study we propose an evaluation system to assess the performance of the proposed vehicle control algorithm. The evaluation system is composed of virtual vehicles, central control system, virtual wayside facilities, monitoring equipments. The virtual vehicles are made up by the laptop computers and the central control system employs Power PC process of Motorola Inc. The wayside facilities are implemented by employing the PXI module of the National Instruments Corporation. In order to test the proposed evaluation system a test algorithm is used, which has been simulated in the combined simulation system between Labview Simulation Interface Toolkit and Matlab/Simulink.

  • In the R&D of the Defense Weapon System, the evaluation of technical and operational aspects has been developed with the military's own test evaluation system, and organizations and procedures have been established and implemented. However, with the recent advancement of information and communication technology in the private sector, it is often necessary to test-apply it to the field by enhancing the operability and suitability of technologies required for defense before development is complete. This paper investigates and analyzes the process for conducing empirical tests on the latest AI vaccine system R&D prototype organized by the Ministry of Science and ICT which proposes an improved demonstration plan for the existing military information system test evaluation procedure. In addition, under the specificity and security of the defense environment, we would like to present a practical demonstration plan and the improvement of the process for demonstrating the security technology prototype.

  • This paper deals with a design of a platform to simulate PRT vehicle operational control algorithms using on-board embedded process board. The configuration of the platform is composed of the central control module, the station control module, man-machine interface and monitoring module. Since PRT system needs inherently very reliable vehicle operational control algorithm in order to avoid the impact between vehicles, it is very important to construct a simulation platform to test a designed vehicle operational control algorithm during the development process For the test of the proposed platform a path of the each moving vehicle is predefined in the central control system before the dispatch order is given to the vehicle. The simulation results show the effectiveness of the proposed simulation platform for test and evaluation of the PRT operational control algorithms.

  • The most essential ROC(requirement operational capability) in order to assure the effectiveness of the C4I Systems in NCW Environments is the seamless and stable interoperability between systems. The U.S. Armed Forces that perceived the importance of interoperability, prepared the framework to apply from the proposal of requirement to every step of acquisition process. The Korea Joint Chiefs of Staff is also developing a similar system in order to assure the interoperability between command control(C4I) systems. In the paper, we specify the needs of standardization of test systems and international trends on the technology, and propose an interoperability test & evaluation system based on a standardization conformity method to improve the interoperability test & evaluation for the C4I systems in NCW environments. Finally we show an example of the implementation of the test system and its application to C4I systems to verify the proposed test system.

  • A research for application of LDSMC(Low Density Sheet Molding Compound) composite is in progress for lightening the weight. This paper has performed fatigue test and simulation of external panel for Korean commercial vehicle. Before the fatigue test, static test was carried out. From the test, the structural safety was investigated using Goodman diagram. After the static test performance, the fatigue test was conducted at a range of load frequency 5Hz, a stress ratio(R) of 0.05 and an endurance limit of 106 to obtain the S-N curve. The S-N curve is applied to the fatigue analysis of the external panel assembly. The result of FEM analysis was in accord with the experimental result within 83% confidence. It showed that the process to set up the safety range of allowable error is required in process of the design and simulation verification.
