One aspect that has mostly been overlooked in traditional economic lot-sizing is the implication of decisions on manual tasks and workload. Although lot-sizing decisions can have a significant impact on required manual material handling and on human performance, works that consider ergonomic aspects in lot-sizing are rare. This paper presents a model that integrates ergonomic aspect in terms of...

An approach for ergonomic evaluation of hospital service quality (EQUALHI) is proposed. It is based on a checklist tool using a neural networks-based evaluation model. This approach enables the determination of the most important ergonomic criteria and the generation of recommendations for improving the hospital service quality. EQUALHI is illustrated and validated by a study in 50 smalland med...

In this study, an investigation was conducted into the extent to which ergonomic requirements for work on computers are met in Greek office workstations. The ergonomic requirements considered were those included in Council Directive 90/270/EEC (1990) of the European Union and the ISO 9241 (1997) standard. 593 office workstations were assessed using an assessment tool consisting of 70 assessment...

UNLABELLED This study investigated the effectiveness of a workstation ergonomic intervention for work-related posture and low back pain (LBP) in Video Display Terminal (VDT) workers. 100 VDT workers were selected to receive the ergonomic intervention, whereas 100 were assigned to a control group. The two groups were then crossed-over after 30 months from baseline. Follow-ups were repeated at 5,...

The aim of the paper is to describe a possible direction of development and theoretical model for ergonomic research in the Virtual Reality (VR) field dedicated to psychotherapy applications. Through considerations on the strong points and limitations encountered during two different projects dedicated to the creation of virtual reality environments (VRE) for use in psychotherapy, it comments o...

The effectiveness of ergonomics application is achieved in the course of this research by reviewing ergonomics literature, Internet searches and case studies of a number of work related musculoskeletal disorders (WMSD's) and other ergonomic related workplace incidence rate. The results of ergonomic intervention control measures such as engineering controls, administrative controls and personnel...

The growing concern for the welfare of workers in the work environment, the importance of widespread use of ergonomics in the different sectors of industry. Yet most corporate practices that work with rudimentary or great need for human handling of materials is not fully in line with the ergonomic aspects. Given this, this article aims to identify ergonomic hazards in mining to later propose im...

The objective of this research is the development of an effective design of an assembly line for heaters production by taking into consideration work measurement, line balancing and ergonomic problems. As the assembly line is still not in existence and no data are available, it is quite difficult to evaluate, for each assembly line workstation, the work assignment, the assembly times as well as...

This paper evaluates the effect of ergonomic factors on task performance and trainee posture during laparoscopic surgery training. Twenty subjects without laparoscopic experience were allotted into 2 groups. Group 1 was trained under the optimal ergonomic simulation setting according to current ergonomic guidelines (Condition A). Group 2 was trained under non-optimal ergonomic simulation settin...
