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.

Operator Workload

In the context of system design, technology assessment often proceeds in a bottom-up fashion, beginning with an evaluation of individual candidate system technologies. Issues of technology integration and human factors considerations are not addressed until later in system development. This paper proposes the use of a top down approach to technology assessment. The top-down approach has the advantage of evaluating technologies along dimensions of system utility, as well as technical performance, and treating human factors early in conceptual design. A technology forecasting and assessment methodology is described wherein technologies can be evaluated quantitatively in terms of technical performance, system utility, and operator workload.

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.

Box Method

An event is a means for students to improve their soft skill and hard skill. In college, one kind of event that usually held regularly is an exhibition. It is usually held around the universities environtment, but in practice there are still some shortcomings, such as the registration process is done manually, attendance of participants that are not integrated with the system, and unavailability of certificates for participants who have attended the event. Since the outbreak of Covid-19, organizing the events must be done online, so we need a system that can accommodate this. Therefore, this study aims to create an event management system that can manage exhibition event data. Besides, the system is also equipped with a feature to generate an E-Certificate that has a QR Code embedded. The method used in this study is Extreme Programming, with its flexible nature toward changes to facilitate the process of system development. The testing in this study is using black box method, with the test results show that all functional in the system can run well in accordance with user expectations. The use of the Extreme Programming method produces a quality system, because users are involved during the system development process.

The San Pedro Bay Ports of Long Beach and Los Angeles continue to provide vital rail connections to the rest of the country. The Rail Enhancement Program sets forth the rail improvements necessary to maintain performance as cargo volumes grow through the year 2035. Implementation of the Rail Enhancement Program has faced hurdles including environmental permitting, funding and competing stakeholder concerns. Cargo growth eased in the years approaching 2010, but the timing of proposed improvements to the rail infrastructure remains critical and challenging. The Rail Enhancement Program is the result of work over the past ten years. Conditions affecting the program have continued to change since the original Rail Master Planning Study of 2000. Updates to the Master Plan have been performed in 2005 and 2010. These documents provide analyses and recommendations for rail improvements to maintain adequate rail service on the Alameda Corridor and through the Port to its rail yards. In developing the Rail Enhancement Program, simulation is used to understand the impacts of increasing cargo volumes on the rail system and to investigate infrastructure and operating improvements required to address deficiencies and to determine improvements to efficiently handle projected traffic. This paper describes the development process with a summary of the analysis methods, resulting proposed rail projects, implementation process and current status of implementation. The steps of the rail system development process include the following: • Evaluation of existing and proposed rail operations; • Conceptual design of over forty potential rail improvement projects; • Analysis of the capacity of existing and proposed facilities; • Scheduling of project development to meet demand; • Estimation of environmental, community and regional impacts and benefits; • Determination of schedule including environmental permit requirements; • Development of project funding plans; and • Preparation of engineering designs and construction documents. The paper will conclude with a summary of the status of key projects from the Rail Enhancement Program. Implementation of the Rail Enhancement Program has included permitting, funding and design efforts on individual projects. The projects currently under development total $1B out of the overall $2B program. The Rail Enhancement Program provides significant benefits to operating efficiencies, environmental impacts and economic impacts. Implementation has been a challenging effort and illustrates the myriad obstacles facing public infrastructure development.
