Operator Workload

The Army developer community needs to be attuned to the need for addressing operator workload issues within the framework of the materiel acquisition process. Brief descriptions are given of: (a) the major acquisition approaches; (b) the Manpower and Personnel Integration (MANPRINT) program; and, (c) operator workload. The interrelationships between these three areas are considered. Workload is important because it affects the ability of the operator to perform required tasks; hence, system performance can be affected by workload. MANPRINT provides a framework for addressing operator workload issues and for formalizing workload analysis requirements.

Operator Workload

This paper describes the 4th-generation model of the Human Operator Simulator (HOS-IV) as implemented on an IBM PC AT microcomputer. HOS is a general purpose simulation tool for modeling the cognitive, perceptual, and motor activities of an operator who is performing a set of tasks during the course of a mission. HOS provides the capability to model the hardware system and the external environment which impact operator workload and system performance. Discussed are the new features of HOS-IV including the user-oriented interface, knowledge representation scheme, and enhanced modeling capabilities.

Operator Workload

We examined how varying the transparency of agent reasoning affected operator workload in a route selection task, and how the differing measures of workload compared in assessing and understanding cognitive workload. Participants guided a three-vehicle convoy safely through a simulated environment of which they had a limited amount of information, while maintaining communication with command and monitoring their surroundings for threats. The intelligent route-planning agent assessed potential threats and suggested changes to the convoy route as needed. Each participant was assigned to one of three agent reasoning transparency conditions. Contrary to our hypothesis, NASA-TLX Global workload measures indicated that workload decreased slightly as access to agent reasoning increased. However, psychophysical measures of workload disagreed with NASA-TLX global results. Comparison of individual NASA-TLX workload factors with the psychophysical measures indicated that performance satisfaction was highest in the intermediary transparency condition, and the addition of ambiguous information in the highest transparency condition increased effort and resulted in increased complacent behavior. Recommendations for future workload analysis are offered.

Abstract Recently, the work of climbing coconuts, especially in Aceh Province Indonesia still uses traditional methods, namely by climbing coconut trees directly. Traditional climbing is very high risk because it can fall which threatens the safety of life. Besides that, this job is also a heavy work category because it requires a lot of energy to do it. Therefore, the analysis of operator workload on climbing coconut trees using portable coconut climbing equipment is expected to be useful for developing tool designs and methods for climbing coconuts that are safer, more comfortable and more effective. The calculation of the operator’s workload is based on heart rate measurements, where three operators have their heart rate data taken during coconut tree climbing activities, either manually or using portable climbing tools. The workloads analyzed are qualitative and quantitative workloads. The results of the workload analysis indicate that climbing is traditionally classified as a “medium” job with an average IRHR value of 1.45, while using portable climbing equipment is classified as heavy work with an IRHR value of 1.54 The traditional climbing energy consumption rate is 3.29 kcal/hour.kg-ow (kilocalories per hour per operator’s weight), while using a portable climbing equipment is 3.82 kcal/hour.kg-ow. The high level of operator workload is largely determined by the operator’s habits in doing climbing as well as skills that must be trained in operating the tool. However, in terms of operator safety, the use of portable equipment has a higher level of security because there are footrests and handrails as well as seat belts.

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.

Simulation Package

Computerized simulator trainers require varying degrees of instructor participation in training exercises and student performance evaluation. An estimation of instructor workload before the system has been fully developed is essential for an effective functional allocation of human and computer capabilities. One approach for estimating operator workload is simulation. The Hughes Design Analysis System (DAS) is an interactive and graphic simulation package. The present paper describes: (1) how DAS has been used for an instructor workload analysis, (2) the analysis method, (3) the results, and (4) the recommendations given to system designers.

Production Target

The production process is one of the main activities of manufacturing companies that need their continuous improvement and continuously. There are several factors that affect productivity, such as job stress and workload. The workload is shared with uneven to make the work environment uncomfortable. The production data in April 2017 explaining that the sanding small grand piano average produces for 20 units piano/day, with a production target of 21 units piano/day production target has not been achieved. The lack of achievement of these targets due to the difference between the expected level of ability with the capacity level. In this study focused to determine the operator workload on sanding small grand piano is included in the painting section. The workload is calculated using the method of Full-Time Equivalent (FTE). The results showed that the operators have overloaded with FTE scores of both 1.33, 1.35 and 1.34 While the operators have an underload workload with a value of FTE 0.94. 0.64, 0.72. Therefore, Kaizen activity such as balancing jobdesk and modification stopper were applied to reduce the waste. Workload after kaizen plan has decreased each 0.02 FTE with change of work element, each operator has a uniform workload with an average FTE value of 1.13 (underload).
