Even though a large amount of ergonomic data and recommendations are available, tools, equipment and products are quite frequently subject to considerable ergonomic deficiencies. The reason for this is that knowledge of ergonomics is not as widespread as the expert would like it. The designer of work places and equipment usually has a rather small background of ergonomics. In many cases it is difficult even for the ergonomist to compress the available knowledge into tables and charts. A computerised assistance system could be of great help

Abstract This paper aims to provide a comprehensive overview of the field of ergonomics, with a specific focus on the application of virtual simulation in the context of manual assembly stations assisted by collaborative robots. The theoretical part of this paper presents a concise introduction to the origins and key figures in the field of ergonomics, highlighting the importance and relevance of this discipline. It also discusses the current methods of ergonomic evaluation and the necessary steps involved in conducting such assessments. Furthermore, it delves into the existing standards, associations, and organizations related to ergonomics, as well as the software solutions available for ergonomic analysis. A case study is presented which demonstrates how to perform an ergonomic analysis using the Ergonomics Evaluation module within the 3D Experience platform. The methodology follows a systematic approach, starting with a physical environment simulation to identify key positions for virtual evaluation. These positions are then simulated using a representative 3D model of the assembly station and selected manikins. The chosen ergonomic analysis method is tailored to the specific movements involved in the assembly activity.

Industries need a mechanism to monitor the workers’ safety and to prevent Work-related Musculoskeletal Disorders (WMSDs). The development of ergonomics assessment tools helps the industry evaluate workplace design and worker posture. Many studies proposed the automated ergonomics assessment method to replace the manual; however, it only focused on calculating body angle and assessing the wrist section manually. This study aims to (a) propose a wrist kinematics measurement based on unobtrusive sensors, (b) detect potential WMSDs related to wrist posture, and (c) compare the wrist posture of subjects while performing assembly tasks to achieve a comprehensive and personalized ergonomic assessment. The wrist posture measurement is combined with the body posture measurement to provide a comprehensive ergonomics assessment based on RULA. Data were collected from subjects who performed the assembly process to evaluate our method. We compared the risk score assessed by the ergonomist and the risk score generated by our method. All body segments achieved more than an 80% similarity score, enhancing the scores for wrist position and wrist twist by 6.8% and 0.3%, respectively. A hypothesis analysis was conducted to evaluate the difference across the subjects. The results indicate that every subject performs tasks differently and has different potential risks regarding wrist posture.

This paper presents the results of an implementation evaluation for a participatory ergonomics project, in two plants run by a company involved in primary aluminium processing. The logbooks kept by the ergonomists, together with observations of project meetings and post-intervention interviews with Ergo group members, were the basic materials used in analyzing the implementation. The analysis includes a comparison between the projected and actual outcomes of the project, examines the contextual factors that explain the gaps observed, and questions the principles underlying the intervention. The results point to the need for ergonomists to have a dynamic vision of implementation evaluations, which will allow them to adjust and refine their intervention theory.

Due to the high-risk nature of musculoskeletal disorder development in dentistry, ergonomic education and evaluation are needed in predoctoral programs. The purpose of this pilot study is to investigate perceptions of ergonomics within the School of Dentistry (SOD), current ergonomic clinical practices among third- and fourth-year dental students, and dental students' level of knowledge of ergonomics. The study was conducted utilizing an explanatory sequential mixed methods design to collect both quantitative and qualitative data. While the data collection occurred in three phases, this article will primarily focus on Phase III. The three phases of data collection were: Phase I consisted of a questionnaire distributed to all dental students; Phase II consisted of clinical observations of third- and fourth-year dental students' ergonomic postures during patient care, and Phase III consisted of SOD faculty focus groups to determine perceptions of ergonomic education with the predoctoral curriculum. Data revealed three overarching themes: (1) Didactic to clinical disconnect, (2) Elective impacts, and (3) A ready commitment. Phase I yielded a response rate of 84% (n=135). Phase I responses noted that 81.5% (n=110) of the dental students reported experiencing musculoskeletal pain. Ninety-three dental students reported receiving one or two lectures on ergonomics; however, 60% (n=27) failed to implement proper ergonomic postures while caring for patients in the clinical environment during Phase II. Phase III, revealed faculty support of ergonomic evaluation and correction among dental students. The results indicated a need to establish and implement an ergonomic evaluation and corrective program within the SOD

The study investigated the organisational ergonomics framework and Business Educators’ job commitment in universities in Rivers State. Two research questions were answered, while two hypotheses were tested. A correlational research design was adopted for the study. The population of the study comprised 47 business educators from three universities in Rivers State. The census sampling technique was adopted due to its manageable size. Two structured instruments (OEFQ and BEJCQ) validated by experts in business education and measurement and evaluation were used for data collection. The reliability index of 0.93 and 0.76 was obtained, respectively, using Cronbach’s alpha. Data were analysed using mean, standard deviation, and Pearson Product Moment Correlation (r). A post-hoc t-transformation test was also carried out to test the significance of the correlation coefficient. Findings from the study revealed a positive and significant relationship between production ergonomics, proactive ergonomics, and Business Educators job commitment in universities in Rivers State. Based on the findings, the researchers concluded that the organisational ergonomics framework is a comprehensive approach that improves workplace ergonomics and further recommended that university management should provide ergonomic tools and equipment that are adjustable and suitable to individual body sizes and capabilities that can help to prevent musculoskeletal disorders and improve overall comfort. Institutions should also establish an ergonomic committee with the responsibility of training faculty members about proper ergonomics as well as conducting regular evaluations of equipment and tools.

Probing into the industry characteristics of construction operations and the necessity to make ergonomic improvement for construction operations, this paper analyzed the current research situation of the literature both at home and abroad which apply ergonomic principles to make improvement in construction operations. This study shows that the existing research on ergonomic improvement of construction operations mainly focus on construction safety and specific operations improvement, at the same time, the system research on the ergonomic improvement of construction operations is less. Making a China's leading internationalized construction service company as the object of empirical research, this paper designed the evaluation index system of construction operations’ man-machine-environment system from three factors of human, machine and environment. And applying the Fuzzy Comprehensive Evaluation Method, the paper evaluated the validity of the man-machine-environment system. At last, aiming at the evaluation results, some improvements were given in view of Ergonomics.

By virtual reality technology and ergonomics theory, a basic method of ergonomic analysis on virtual maintenance of civil airplane is herein presented based on DELMIA modeling tool. The method is characterized by two steps: (1) establish the appraisal indexes of ergonomics on virtual maintenance of civil airplane; (2) give a quite complete ergonomic analysis and confirmation system flow chart. By defining maintenance cases and simulating the virtual maintenance process under the DELMIA platform, it is possible to accomplish the ergonomic analysis and evaluation with respect to the ergonomics indexes. The strengths of this method are in its ability to provide the available data and experience for further ergonomic design research and in its broadly applicable 3-D digital human model well suited for computer simulation. Furthermore, because the ergonomic analysis problem in maintainability design is indeed a simulation and confirmation process, the use of simulation techniques and confirmation techniques in this work lends itself to maintainability concurrent design of civil airplane. The ergonomic analysis method is demonstrated using vision analysis as an example.

BACKGROUND AND SIGNIFICANCE. Various studies have identified physical risk factors for musculoskeletal disorders (MSDs) associated with hand harvesting of crops, due to repetitive motions, lifting or carrying of heavy loads, and working in flexed trunk postures. A paucity of research exists on ergonomic risks to tomato farmworkers. The available studies have estimated risk based on self-reports of injury and semi-quantitative measures. METHODS. A partnership between East Tennessee State University (ETSU) and a migrant health center (Rural Medical Services) has identified some of the occupational health needs of this population. With the aid of surface electromyography (sEMG), an objective-quantitative tool, a more refined understanding of ergonomic health risks for this population will be developed. The purpose of this study is to evaluate the muscle load and fatigue induced on the anterior deltoid and upper trapezius muscles during three tasks: driving stakes into the ground, tying of tomatoes to stakes, and hoisting of a 35-pound bucket full of tomatoes. Space for a mock test plot, where the study will be conducted, is available at the ETSU’s Valleybrook facility. Muscle activity recordings will be obtained from 15 tomato farmworkers. Spectral analysis and the amplitude probability distribution function (APDF) will be used to assess fatigue and muscle load respectively. A repeated measures ANOVA will be employed in the study. ANTICIPATED RESULTS. Findings of this study should show that localized muscle loading increases muscle fatigue. Neuromuscular demand should vary, depending on the type of task performed. Stake pounding may show a higher neuromuscular demand than the other tasks. AIM 1. Evaluate the magnitude of muscle activity during three simulated tomato-field tasks and measure the intensity of movement during the stake pounding task. AIM 2. Compare estimates of muscle fatigue and muscle load induced on the anterior deltoid and upper trapezius muscles during three simulated tomato-field tasks.

Workers within production and assembly lines are often exposed to ergonomically unfavorable tasksand conditions. Reaction forces and reaction torques generated by industrial power tools may causenot only discomfort but also health issues and injury. The forceful tasks in combination with highlyrepetitive hand-arm motions and prolonged tool use paves the way for loss in workforce capacitywhich in turn can lead to great losses in productivity and product quality. An umbrella term for themany injuries and diseases that may arise from the use of such tools is Cumulative Trauma Disorders(CTD).This study aimed to investigate the ergonomic effect of power tool use for various tool and taskrelated conditions. The study required the setup of a test rig with a simulated handle of the tool. Theergonomic impact was assessed by measuring the torques associated with different tighteningstrategies, as well as measuring the angular displacement of the tool handle. By varying the jointstiffness and workplace orientation, the complexity of the task was varied and thus quantified.Measurements of muscle activity during each tightening procedure provided a quantification of thephysiological impact on the operator. By combining the measurements on the operator withsubjective assessment of perceived exertion and discomfort, a more holistic perspective on thetightening procedure was obtained.The results obtained from the study stressed the negative impact on the operator which the QuickStep tightening strategy on medium hard joints implies, regardless of workspace orientation. TheTurbo Tight and Tensor Pulse tightening strategies turned out to generate the lowest reactiontorques and handle deflections, regardless of joint stiffness and workspace orientation. The findingsfrom the muscle activity measurements in combination with the subjective evaluation methodsfurther confirmed the mildness of the Turbo Tight and Tensor Pulse strategies. Moreover, horizontalworkspace resulted in lower tool handle deflection compared to vertical workspace for all tighteningstrategies and joint stiffnesses.
Många antällda på monteringsband exponeras ofta för ergonomiskt ofördelaktiga arbetsuppgifter och arbetsförhållanden. De handhållna monteringsverktyg som används genrerar ofta reaktionskrafter som i många fall kan orsaka en känsla av obehag eller ge upphov till mer bestående hälsobesvär. De kraftfulla och repetetiva arbetsuppgifterna som montering många gånger innebär kan bana väg för förluster i arbetskraftskapacitet, vilket i sin tur kan leda till stora förluster i produktivitet och produktkvalitet. En paraplyterm för de många åkommor och besvär som kan uppstå som ett resultat av användandet av handhållna monteringsverktyg är ’förslitningsskador’ (Cumulative Trauma Disorders på engelska). Målsättningen för denhär studien har varit att undersöka de ergonomiska effekter som användandet av handhållna monteringsverktyg innebär vid olika vektygs- och arbetsuppgiftsrelaterade parametrar. Studien genomfördes med hjälp av en test rig där ett simulerat verktygshandtag utnyttjades. Den ergonomiska effekten på användaren undersöktes genom mätningar av uppnådda reaktions moment och handtags vinklar associerade med olika åtdragningsstrategier, styvhet av förband samt orientering av arbetsyta. Genom att mäta muskelaktiviteten i underarmen hos testpersonerna erhölls en kvantifiering av den fysiologiska effekten på testpersonerna. Mätningarna av vinkel, moment och muskelaktivitet kombinerades med subjektiva skattningsmetoder för att på så sätt kunna erhålla ett mer holistiskt perspektiv på åtdragningarna och deras effekt på människan. Resultaten från studien underströk de negativa effekterna av åtdragning med Quick Step strategin på medium hårda förband, oavsett orientering av arbetsytan. Turbo Tight och Tensor Pulse strategierna genererade de lägsta reaktions momenten och handtags deflektionerna. Resultaten från muskelsaktivitetsmätningarna och de subjektiva skattningsmetoderna bekräftade den relativa mildheten hos Tensor Pulse och Turbo Tight strategierna. Dessutom påvisades att åtdragningar som sker på en horisontell arbetsyta resulterade i lägre handtagsdeflektion jämfört med åtdragningar på en vertikal arbetsyta, oavsett åtdragningsstrategi och styvhet hos förband.

The aim of the study was to evaluate ergonomics in a Base Metal Refinery (BMR). The hypothesis tested was that the machinery and equipment used and the postures of the workers and the load handled are not in line with good ergonomic standards and practices. Anthropometrical measurements were taken from 11 1 workers and the loads they handled, their posture while performing the work and the heights of different workstations. Self administered questionnaires were completed by all the workers so as to determine how the feel about their work and an observational data was recorded in order to observe the way the work was performed. Different anthropometrical measurements taken included stature, weight, vertical grip reach, forward grip reach, shoulder grip length, shoulder height/hip height. Different variables including height of the workstation, weight handled, type of work done and frequency of handling were also measured. Evaluation of medical records and incident reports were also carried out to determine whether these records support the hypothesis to be tested or not. Most of the workstations were not ergonomically designed and the work performed in the Base Metal Refinery was done in a standing position and repeated for most of the work shifts. Anthropometrical data was collected so as it can be compared with the type of work performed the duration of the work and whether the workstations were designed to fit the workers. Workers in the BMR were exposed to handling loads which were higher than the NIOSH recommended weight of 23kg, the work was highly repetitive and the workers had to bend awkwardly while performing the work. Therefore this disagrees with the hypothesis which states that the machinery and equipment used and the postures of the workers and the load handled was not in line with good ergonomic standards and practices. This statement was also supported by the incidents reports and the medical records which showed that most workers were booked for a long time due to lower back pain, and more incidents occurred due to handling loads. In BMR most incidents, injuries and illnesses were common amongst cell workers than any occupation within the industry. High incidents and absenteeism due to lower back related illnesses can be directly associated to the type of work performed and the amount of load handled. Most of the workstations were either too high or too low therefore forcing the workers to bend at the waist or his neck so as to properly observe the task, and this proves that BMR was not designed to fit the workers, the way the work was performed, the posture of the worker, the repetitive nature of the work and the weight handled were exceeding the ergonomic standards and practices.

This project tested the hypothesis that non-experts' rankings of ergonomic stressors differ from those of health professionals. Tennessee ranks fifth in the production of tomatoes, an industry in which stoop labor, hand harvesting, and packing predominate. Specific parts of tomato workers' bodies are at risk of ergonomic injury such as, shoulders (loads), backs (stoop labor), lower extremities (posture), and upper extremities (repetitive motion). Of equal importance is our expectation that the scores assigned by non-experts will correlate with those of experts, leading to a community consensus for action and practical intervention research. Video footage of harvesting and sorting was analyzed using the Rapid Entire Body Assessment method, revealing movements and postures likely to be injurious. A panel of 13 health professionals (“experts”) and industry personnel (“non-experts”) were assembled to rate job task video segments in tomato harvesting and packing using the REBA method. Analysis of variance (ANOVA) was used to analyze the extent to which raters agree on the major body parts at risk of cumulative trauma disorders. Agreement and variation among professional groups, as well as intra-rater variability, were assessed . The possibility of achieving consensus among various professional groups with respect to the most dangerous tasks is discussed.

Several studies have shown that the work environment affects company performance. The managers are seldom aware to which extent work environment problems affect productivity, quality of delivery and sick-leave in their organisation. The present literature study showed that improvements regarding physical ergonomics generally are shown to be cost-effective. The most beneficial way of working is through proactive measures interactively with employees. An efficient, systematic way of performing risk assessments and interventions reduce the need for a calculation method. This study identified propositions for properties of calculation methods. These propositions were : “Simplicity, high usability”, “Right content for the target group”, “High ability to measure risk”, “Focus on staff”, “Correct standardised values”, “Right focus” and “Optimal design”. Scania CV, a producer of trucks and buses, has developed a calculation model for cost-effectiveness of ergonomic interventions. Evaluation of this model with semi-structured interviews showed agreement regarding the need of a simplified calculation method, based on systematic risk assessments.
Ett flertal studier har visat att arbetsmiljön påverkar företags effektivitet. Företagsledningen är sällan medveten om till vilken grad arbetsmiljö-problem påverkar produktivitet, kvalitet och sjukfrånvaro. Litteraturstudien i detta projekt visade att förbättringar inom ergonomi generellt sett är kostnadseffektiva. Det är mest gynnsamt att arbeta proaktivt samt participativt, det vill säga i samarbete med medarbetarna på den lokala avdelningen. Ett effektivt, systematiskt arbete med riskbedömningar och interventioner minskar behovet av att göra en beräkning av lönsamheten. Propositioner för egenskaper hos kostnadseffektiva beräkningsmetoder togs fram i denna studie. Dessa propositioner var; ” Enkelhet och god användbarhet”, ”rätt innehåll för målgruppen”, ”hög förmåga att bedöma risk”, ”personalfokus”, ”korrekta standardiserade värden”, ”rätt fokus” och ”optimal design”. Scania CV, producent av lastbilar och bussar, har tagit fram en beräkningsmodell för kostnadseffektivitet hos ergonomiska interventioner. Utvärderingen av denna modell med semistrukturerade intervjuer visar god samstämmighet i att det behövs enkla kalkylmetoder som grundar sig på systematiska riskbedömningar.

Um dos principais objetivos da ergonomia é ter uma carga de trabalho adequada, buscando a melhoria dos níveis de conforto, satisfação, eficiência e segurança no trabalho, caso contrário, sua inadequação pode influenciar a saúde e segurança do trabalhador, além de afetar a organização. O objetivo geral deste estudo é identificar as causas raiz de uma carga de trabalho inadequada com intuito de compreender os fatores influentes e suas interligações visando melhorar a condição de saúde e segurança dos trabalhadores. Os objetivos específicos são: (i) entender e definir as dimensões da carga de trabalho através de uma revisão sistemática de literatura; (ii) identificar os fatores influentes centrais, ou seja, causas raiz, da inadequação da carga de trabalho através da análise de uma revisão sistemática utilizando ferramentas do Processo de Pensamento; (iii) avaliar a carga de trabalho e suas inadequações de forma participativa, através da mensuração desta e da identificação de suas causas raiz em uma empresa de manufatura. Para alcançar cada um dos objetivos o presente trabalho foi estruturado na forma de três artigos, associados a cada um dos objetivos específicos. Assim, o trabalho foi composto por uma revisão sistemática de literatura (Artigo 1), análise de uma revisão sistemática (Artigo 2) e um estudo de caso aplicado (Artigo 3). O primeiro artigo entendeu e definiu as dimensões da carga de trabalho. No segundo, identificou-se os fatores influentes centrais da inadequação da carga de trabalho através de uma revisão sistemática. Já no terceiro artigo, foi realizado um estudo de caso, composto pela avaliação da carga de trabalho através da NASA TLX, demonstrando a carga de trabalho de máximo risco (carga de trabalho geral). Neste também mensurou-se, de forma participativa, os fatores centrais desta inadequação através de ferramentas do processo de pensamento. O resultado final permitiu perceber poucos estudos definindo carga de trabalho entre artigos empíricos, não havendo uma definição padrão. Percebeu-se que o foco dos artigos não são na abordagem da adequação desta carga de trabalho. Permitiu-se identificar as causas raiz de uma carga de trabalho inadequada, propiciando uma análise profunda das relações gerais do problema, através da lógica causa e efeito, incluindo os fatores influentes e suas interligações.
A major goal of ergonomics consists in having an adequate workload in order to improve levels of comfort, satisfaction, efficiency and safety. Otherwise, its inadequacy can influence health and worker’s safety and affect the organization. The aim of this study is to identify the root causes of inadequate workload in spite of understanding the influencing factors and their interconnections to improve the workers health and safety. The specific objectives are: (i) understand and define the dimensions of the workload through a systematic literature review; (ii) identify the substantial influencing factors (root causes) of the inadequacy of the workload by analyzing a systematic review using Thinking Process tools; (iii) evaluate the workload and its inadequacies in a participatory manner, by measuring and identifying their root causes in a manufacturing company. To achieve each objective, this study was structured with three articles associated with each of the specific objectives. Therefore, the work is consisted of a systematic review of the literature (Article 1), analysis of a systematic review (Article 2) and an applied case study (Article 3). The first article understood and defined the dimensions of workload. In the second, we identified the major influencing factors of inadequate workload through a systematic review. In the third article, we conducted a case study, comprising the assessment of workload through the NASA TLX, demonstrating the maximum risk workload (overall workload). The end result allowed us to perceive few studies defining workload between empirical articles, there is no standard definition. It was felt that the focus of the articles are not in addressing the appropriateness of this workload.

To decide in advance the amount of resources that is required next week or next month can be both a complicated and hazardous task depending on the situation, despite the known time frame when the resources are needed. Intermittent demand, or slow-moving demand, that is when there are time periods without demand and then suddenly a time period with demand, becomes even more difficult to forecast. If the demand is underestimated it will lead to lost sales and therefore lost revenues. If the demand is overestimated, in the best case the stock is increased or in worst case, the items lie unsold until they become obsolete. The items with intermittent demand can have a value of up to 60% of the total stock value for all items.This thesis addresses the topic of forecasting intermittent demand and how to measure the accuracy of the chosen forecast method or methods. Four forecasting methods are tested on almost 18 months of empirical demand data from a manufacturing company. The tested forecasting method are single exponential smoothing, Croston and two modification of the Croston method, one by Syntetos and Boylan the other by Segerstedt (modified Croston). Four start values and eight smoothing constants are tested. The methods are evaluated with different accuracy measures; variance (MSE and MAD), bias (CFE, the maximum and minimum value of CFE) and sMAPE. In addition with a new complementary measure of bias; Periods in Stock (PIS), PIS considers the time aspect, when the forecast error occurred not just the error size. Also two variants of MAD and MSE are tested. To improve the evaluation of the bias measures, the percentages of demand occasions that can not be fulfilled are used. The relationship between the different errors for a certain method is examined with principal component analysis (PCA). The errors are also examined with logistic regression to find out if a certain forecasting method is favoured by certain accuracy measures. The logistic regression is based on descriptive statistics for time series plus the mean absolute change that considers the sequence of the time series as well as the variation. Ranking and error quotients between different methods are other applied methods. The results of the research both confirm and contradict earlier findings. Among the confirming research results are the bias among the different methods. Croston and Modified Croston are overestimating the demand, Syntetos and Boylan's Croston variant has a tendency to underestimate the demand. Single exponential smoothing is relatively biasfree when low smoothing constants are concerned. The contradictive results are that CFE is not a suitable measure of bias at least when the number of forecasting periods is limited. The value of CFE can indicate a nonbiased forecast when both PIS and the percentage of unmet demands indicate a biased forecast. PIS is also less sensitive to transient demand events that can distort CFE. PIS is recommended as a bias measure for limited time series, especially considering intermittent demand, along with the percentage of unmet demand. Another result is that MAD is not reliable since the method in certain circumstances favours methods that underestimate the demand.
Att på förhand bestämma vilken mängd resurser som krävs nästa vecka eller nästa månad kan vara både en komplicerat och riskfylld uppgift beroende av situation, trots att man känner till när resurserna behövs. Intermittent efterfrågan, eller lågrörlig efterfrågan, är när många perioder saknar efterfrågan och plötsligt sker en efterfrågan en period. Detta gör det svårare att prognostisera. Om efterfrågan underskattas kommer det att leda till förlorad försäljning och därmed förlorade intäkter. Om efterfrågan är överskattad kommer det i bästa fall att bara leda till ökat lager eller, i värsta fall, leda till osålda produkter och till slut inkurans. Artiklar med intermittent efterfrågan kan utgöra upp till 60 % av det totala lagervärdet för samtliga artiklar.Denna uppsats avhandlar prognoser av intermittent efterfrågan samt hur prognosfelen ska mätas för den valda eller de valda prognosmetoderna. Fyra prognosmetoder utvärderas med nästan 18 månaders empirisk efterfrågedata från ett tillverkande företag. De utvärderade metoderna är exponentiell utjämning, Croston och två modifierade varianter av Croston; Syntetos och Boylans metod samt modifierad Croston av Segerstedt. Fyra olika startvärden och åtta utjämningskonstanter används. Prognosmetoderna utvärderas med olika typer av prognosfel; varians (MSE och MAD), bias (CFE samt max- och minvärde av CFE) och sMAPE. Vidare sker utvärdering med ett komplimenterande mått för bias, Lagerperioder (Periods in Stock, PIS). PIS tar tidsaspekten i beaktande och inte bara storleken på prognosfelen. Dessutom undersöks två varianter av MAD och MSE. För att förbättra utvärderingen av biasmåtten undersöks procentantalet av de efterfrågetillfällen som en prognosmetod inte kan uppfylla.Förhållandet mellan de olika prognosfelen undersöks med hjälp av principal component analysis (PCA). Prognosfelen undersöks även med binär logistisk regression för att utröna huruvida vissa prognosmetoder gynnas av vissa prognosfel. Den logistiska regressionen baseras på deskriptiv statistik för tidsserierna samt medelabsolutförändringen som tar ordningen för tidserien i beaktande såväl som variationen. Rankning och kvoter mellan olika prognosfel från olika metoder är andra tillämpade metoder. Resultatet av forskningen både bekräftar och motsäger tidigare forskning. Bland de bekräftande resultaten är den bias olika prognosmetoder har. Croston och modifierad Croston överskattar efterfrågan, Syntetos och Boylans metod underskattar efterfrågan. Exponentiell utjämning är förhållandevis fri från bias när utjämningskonstanterna har låga värden. De avvikande resultaten är att CFE inte är lämpligt att använda när antal prognosperioder är begränsat. Värdet för CFE kan indikera att prognosen är fri från bias när både PIS och procentandelen icke mött efterfrågan. PIS är dessutom mindre känslig för transienta efterfrågehändelser som kan förvränga CFE. PIS rekommenderas som ett biasmått när tidsserien är ändlig, särskilt när det gäller intermittent efterfrågan, tillsammans med måttet procentandelen icke mött efterfrågan. Andra resultat är att MAD inte är pålitlig eftersom måttet, under vissa förhållanden, gynnar prognosmetoder som underskattar efterfrågan

Roads and pavements covered with ice and snow during winter in the Nordic and other cold regions are slippery, which result in the prevalence of slip and fall accidents among not only the public, but also outdoor workers. Literature and injury statistics revealed that the most frequently specified contributory factor for occupational slip, trip and fall accidents in Sweden is snow and ice. Road accident research showed that the largest numbers of traffic casualties occurred during walking, followed by cycling and vehicle transporting. The cost to the community of providing medical treatment to victims of pedestrian injuries resulting from slipping is far greater than that of keeping walking surfaces free from ice and snow. However, in comparison with the size of the problem, little research has been carried out to identify and evaluate slip and fall risk on icy surfaces. Objectives are to present a systems perspective of slip and fall accident, to measure, evaluate and compare the coefficient of friction (COF) of footwear on ice and lubricated floor, to identify advantages of walking experience on icy surface and participating in winter sport in preventing slip and fall accidents, to develop subjective evaluation method for slipperiness measurement and usability assessment of footwear product, to systematically assess the integration of slip resistance, thermal insulation, and usability of footwear, to ascertain the anti-slip effect of materials spread on ice by user trials, and to explore the incorporated approach towards the design of footwear for use on icy surfaces. The following methods of collecting data were used in studies of this thesis: 1) direct observation, 2) videotaping, 3) human perception rating scale, 4) objective COF measurements, 5) retrospective cross-sectional epidemiological study by questionnaire. a systems model involving potential factors was proposed based on a comprehensive literature review (study I). Comparison of objective evaluation of footwear slipperiness on ice and oily floor was used to examine the frictional performance on different underfoot surfaces (study II). Epidemiological survey of slip and fall accidents was carried out focusing on individual experience, winter participation, severity of injuries, footwear, and underfoot surface conditions (study III). Subjective rating scale was developed and used to assess the perception of slip and fall risk and the usability of footwear used on various icy surfaces including anti slip materials spread on ice (study IV). The integration of multiple protection function and usability into winter footwear was also assessed (study IV). A systematic analysis of the slips and falls on icy and snowy surfaces showed that the etiology of slips and falls is multi-faceted. The COF on ice by objective measurements at 0ºC is much lower than that at -12ºC and that on stainless steel. Polyurethane soling material did not provide sufficient friction on wet ice at least when new (without abrasion), although superior on lubricated floors. The footwear tested including winter footwear, professional footwear, safety footwear, and footwear deemed to be slip resistant by users and manufacturers did not provide sufficient protection against slips and falls on wet ice at around 0ºC. Accordingly, slip and fall risk is higher on wet ice than on dry ice and lubricated floor. Slip and fall events reduced with increased living experience in cold environments and winter sport participation. Newcomers with no or less experience were prone to falling, and therefore they should be well informed of potential slip and fall hazards upon arrival in cold region. Slip resistance, thermal insulation and usability of footwear tested were not properly integrated. In addition to thermal insulation, prevention of slip and fall hazard by improving anti-slip property and usability must also be priorities for development of footwear for use in cold environments. Based on the findings, anti-slip footwear, measurement methods for slipperiness on ice and snow, related standards, the role of gait biomechanics and task-related factors should be further developed and studied.

Abstract Logistic activities can cause long-term musculoskeletal problems due to repetitive and incorrect movements, heavy loads, and uncomfortable positions. Ergonomic evaluations are conducted to prevent these risks, optimize workstations, and work processes. Some studies use automatic evaluation of ergonomic indices or frameworks for optimizing workstations and logistics reorganization. However, optimization is often disconnected from real-world case studies. This research work validates a new approach that integrates an automatic ergonomic evaluation and optimization in real-world scenarios, comparing this analysis with traditional manual evaluation method. Our approach is applied to a real logistics case study using a wearable motion capture system and an interactive interface that displays the Digital Twin of the analyzed task. Results show that our approach provides a more accurate evaluation of the ergonomics and an evident time-saving.

The design of aircraft cockpits tends to gradually become more and more human-centered, and the role of pilot in the cockpit has also been given more important responsibilities other than just flying the airplane. Therefore, the ergonomic design of the cockpit will largely affect the work efficiency and workload of the pilot, which can in turn affect the safety of the flight. In this paper, the objectives, objects and criteria of ergonomic evaluation of cockpit layout are defined, and the general evaluation process is put forward. In addition, this paper introduces several different ergonomics evaluation methods for civil aircraft cockpit layout, and recommends suitable evaluation methods according to the characteristics of the evaluation objects in different development phases of the cockpit.

In the field of integral design (systemic design considers people, the activities, objects mediators of these activities and the environment of use of the objects) has been increasing interest to integrate the users during the development process, primarily for the investigation and evaluation stages. In certain university in the Mexican context efforts are made to train Designers with expertise in ergonomics, human factors and methodology associated with the processes of design development. Part of the effort is the constant incorporation of knowledge about the process of design, features and methodologies as well as the inclusion of aspects that allow users consider (ergonomics and human factors) at different stages of the design process. The objective of this proposal is to contextualize the importance of creating a toolkit which classified different methods and techniques and instruments from various disciplines useful for the stages of inquiry and evaluation of the integrated design process, identifying the type of data that sheds (qualitative or quantitative) and its application process and the utility reports to process. In order to improve the design process of inquiry has resorted to using diverse techniques that have allowed an approach to the qualitative and quantitative necessary to include the social, emotional and cognitive users during the development of the design process. Moreover, the assessment is a process of obtaining information and its use through the application of methods and techniques allows us to identify the level of development of a project with respect to the objectives, with the intention of making judgments useful for decisions, i.e. allows assessment feedback in the design process. There are considered two types of evaluation: formative and summative. Formative assessment is an assessment that is done during design to ensure that the product meets the needs of users while evaluation (also called summative or comprehensive) is an assessment that is done when the design is finalized, possessing each type evaluation. An evaluation design should observe all aspects that impact the user interaction with objects and the environment of use of the same, i.e. systemic approach is needed to respond to the questions: Why evaluate? , What evaluate? , Where assess? , When to evaluate?, all with the aim of evaluating the User experience (which involves affective, cognitive , physical and social) so that the methods, techniques and tools for inquiry or evaluation must be properly selected and applied during the design process.

Current models to evaluate and select Advanced Manufacturing Technology (AMT) present deficiencies since human factors and ergonomics (HFE) aspects have been neglected and obviated. Therefore models have emerged that propose the effective integration of these aspects. This chapter presents a literature review emphasizing in authors and methodologies that have addressed this topic. Also, the development of a fuzzy expert system (FES) based on Fuzzy if-then rules with a novel axiomatic design approach for ergonomic compatibility evaluation on the selection of AMT is presented. A numerical example for the selection of CNC plastic molding machines is also included. Literature review was made by using key words on scientific databases such as Science Direct and Ebscohost including papers from the last five years.As results we present a list of authors, methodologies and models that have contributed to ergonomic evaluation of AMT. A fuzzy expert system (FES) was developed and programmed in Matlab ®. It was validated using previous case studies’ results and sensibility analysis. The FES provides a practical way for single or group evaluation for ergonomic compatibility of AMT and may contribute to more complete decision making processes including HFE aspects.

Abstract Digital Human Modeling (DHM) brings in the advantages of reducing the time and cost spent on building physical prototypes and minimizing the risk of conducting human-subject data collection in hazardous settings. However, most of the DHM studies focus on evaluating standardized tasks executed in normal or nominal work conditions. There is a limited existing DHM research that focuses on the analysis of high-risk tasks performed during emergencies. This paper introduces a DHM based design framework that focuses on the ergonomics evaluation of high-risk tasks that are required to be performed during an emergency. The research aims to provide a methodology that can be used to measure the effect on the visibility of the controls due to a fire or smoke emergency in a civilian aircraft cockpit. The design framework described in this paper also automates the repetitive task simulations and ergonomic evaluations, which are typically performed manually by the designer. Thus, the automation module saves time and allows the consideration of a large sample set of anthropometries for assessing ergonomic adequacies. The automation framework also brings in the advantage of making the emergency assessments part of the early design ergonomics analysis digitally, which has not been the focus of traditional ergonomics studies.

The paper describes current state of education and professional development of specialists in human factors and ergonomics in Russia. University education in Russia is regulated by the fixed list of specialities and by the State learning standards. Currently, there are four university specialities that can serve as “umbrella” for education of ergonomists, namely: “System Analysis and Control”, “Biotechnical Systems and Technologies”, “Psychology”, “Design”. Two Russian leading universities offer bachelor and master programs on ergonomics. Postgraduate ergonomics education is available in the form of training courses and courses for preparation of candidate or doctoral dissertation. Any dissertation must be attributed to one of the predetermined scientific specialities. The most relevant speciality is “Occupational psychology, engineering psychology, ergonomics”. Nearly half of all candidates and doctors of sciences who have defended research work on ergonomics have degree in technology, one third – in psychology. Currently, Russian ergonomics society is elaborating procedure for certification of professional ergonomists following the CREE (Centre for Registration of European Ergonomists) model. As a first step to this target, the Standard for certification of the specialists designing human-machine systems has been developed. This standard establishes three evaluation criteria concerning of applicant’s educational level, professional experience, and professional development and self-education.

The software tool EMA (“Editor for Manual Work Activities”) facilitates digital production planning and ergonomics assessment by providing a more efficient and accurate approach to 3D human simulation. EMA uses a modular system for describing human work activities based on a pre-defined library of “complex operations”, which allows the generation and simulation of human movements with highly-automated algorithms. Moreover, EMA includes standard tools for the assessment of ergonomic strains (EAWS – “Ergonomic Assessment Worksheet”) and production time (MTM – “Methods Time Measurement”). After introducing some basic analysis functions of EMA and their typical use cases, this paper presents an evaluation study that examines the validity of EMA ergonomic evaluations in comparison to paper-pencil-assessments with EAWS. Moreover, this paper shows several use cases of the EMA software application in automotive and aviation industry. These applications illustrate that EMA considerably reduces the effort for preparing human simulations and enables the user to analyze ergonomic conditions (body posture, action forces, manual load handling) and productivity (e.g., walk ways) very thoroughly.

Correctly using a rapid upper limb assessment for working postures is crucial to avoid musculoskeletal disorders. Although motion capture technologies and in particular depth cameras are widely used, they cannot be used in large-scale industrial environments due to their high cost and their performance greatly impacted by the surrounding environment. We thus compared the effectiveness of a commercial machine vision algorithm (named ErgoEdge) based on an RGB camera against an application here developed based on the depth camera Microsoft Azure Kinect for the RULA evaluation (AzKRULA). We conducted an experiment where fifteen static postures were evaluated with Microsoft Azure Kinect and ErgoEdge, and the results were also compared with those of an expert in ergonomics. This experiment showed a substantial agreement between the solutions provided by the semi-automatic RULA evaluation and the ergonomic expert and between AzKRULA and ErgoEdge. At the same time, it showed that the RGB camera must be placed on the side of the worker due to the difficulties of the machine vision algorithm in reconstructing from a frontal view, important joint angles in 2D space (e.g., to evaluate the neck and trunk), which can invalidate the RULA evaluation provided by ErgoEdge. Moreover, the RULA evaluation with AzKRULA and ErgoEdge highlighted the need for an in-depth study into the thresholds of the secondary factors (i.e., all the factors for the RULA evaluation that are not computed from the thresholds of joint angles) as the highest differences between the two evaluations and the ergonomist one arises on them.

The manual assembly equipment has been cited as one exposed to several ergonomic constraints, such fractionation is associated with the task of occupation, facilitating the monotony and high number of repetitive movements that may cause occupational diseases of physical and psychological harm. Seeking to adapt the work to the characteristics and skills of professionals in the assembly of the sector totals, ergonomic intervention System Human-Machine Task was performed in an industry located in Recife-PE assembly of water meters, comprising the steps of Ergonomic Assessment, Ergonomic Diagnose and Ergonomic Projects. To meet the objectives of the first stage, unsystematic observations, documentary analysis of records and PPRA PCMSO Company, open interviews and structured questionnaires with workers in the sector were applied. In the second stage, the deepening of the problems found in the first study were from task analysis, systematic observations for analysis of postures assumed, according Worksheet RULA (Rapid Upper Limb Assessment) analysis of the physical costs from the implementation of the diagram discomfort/pain, and anthropometric studies by two-dimensional anthropometric dummies. In the third step, were proposed suggestions for improvements to the problems encountered and prioritized. The results indicated order problems and physical environmental, organizational, job, biomechanical and psychosocial. The high levels of discomfort/pain are justified by inadequate occupational postures combined with repeatability of movements in accomplishing the task.

Abstract This paper aims to present user experience survey results of innovative software assessment technologies available in the market aimed in evaluating risks of industrial-related ergonomic hazards. The scope covers industrial ergonomics softwares currently available for purchase where time-limited free trial is offered, particularly those that utilize 3D Motion Capture Assessment which relies on kinematic inputs aided by non-invasive computer technology and artificial intelligence, and makes use of pre-determined weightings based on biomechanical risk factors. In light of the inclusion criterion, six industrial ergonomics softwares were considered. User field trials were conducted during January to September 2020 among 10 Occupational Health Subject Matter Experts (OH SME) coming from seven oil and gas Group Companies. Each OH SME attended a product demonstration by the shortlisted software vendor, participated in software trial at their respective workplaces, and provided feedback on the software's usability by filling out a survey questionnaire. OH SME responses were then collected for further qualitative analyses. Three of the eligible softwares relied on photo snapshot capturing work activity where subsequent analysis is done through competent professional judgment of qualitative risk. Another three were dependent on 3D Motion Capture Assessment where upper and lower limb motions of employees are digitally captured, recorded, and analyzed. Two of the softwares utilized sensors attached to different parts of employee's body, while one relied on Android/Smartphone snapshot of work activity and analyzed by the software's algorithm. Analyses of OH SME feedback revealed majority of them (n = 7) preferred using 3D Motion Capture Assessment over professional judgment of qualitative risk as an effective tool in evaluation of industrial work-related ergonomic risks. 3D Motion Capture Assessment provided accurate measurements of employee joint postures and postural angles. The tool ensured consistency in risk scoring for a particular industrial-related work activity as the calculation is standardized. The tool's algorithm is aligned with globally accepted assessment tools in evaluating ergonomic risks which enhances its validity. OH SMEs have expressed concerns on use of Android/Smartphone in Critical Infrastructure and Coastal Protection Authority facilities, training time needed in learning the software, and repetitive use of motion sensors among different employees which may lead to personal hygiene issues. 3D Motion Capture Assessment is a novel ergonomics software tool that can be used in real-time and accurate evaluation of ergonomic risks arising from industrial work-related activities. It can replace observational assessment of a work activity that may be prone to professional judgment errors. However, more validation and reliability studies need to be done in future as well as determining association between ergonomics risk scores obtained from the software and prevalence of work-related musculoskeletal disorders.

The ergonomic injuries and solutions have been extensively studied in the construction industry; however, the prevalence of work-related injuries, risky activities, and effective solutions in the transportation industry are not understood. This study aims to explore the prevalence of work-related injuries, risky activities, and potentially ergonomic solutions among transportation workers. The approach to this study included exploration of worker type, injury types, and activities of top concern through historical injury data and an online survey, and proposal and evaluation of ergonomic solutions through onsite observations and field experiments. Results from this study found that back injuries were the most common type of injury sustained. Performing lifting and pushing/pulling activities have caused the most injuries. Back exoskeletons and ergonomic handles were identified as potential solutions to help reduce the risk of injury. Additionally, higher platforms were also suggested to help prevent workers from being forced to perform activities by exerting their back excessively.

The study purpose is to develop methodological support for students’ training for evaluation e-tools for young learners and to check its effectiveness experimentally. The module “Expert evaluation of the quality of e-tools for young learners” is offered for teachers-to-be. The determination of the weighting factor of each criterion by expert evaluations was organized. Educational principles, correlation e-tool content with the curriculum, interactivity, multimedia, assistance system, ergonomic requirements are mentioned. On the basis of the criterion rank, the significance of each criterion was calculated. The indicators to determine the level of preliminary expert evaluations of e-tools are proposed. The results are calculated with nonparametric methods of mathematical statistics, in particular, Pearson’s criterion χ2. The conclusion is the expert evaluation has different activity stages, gradually becoming a common phenomenon. Training teachers-to-be for e-tool expert evaluation at Computer Science, Mathematics, English is a complex process.
