Purpose: The paper aims to present an approach to improve the organisation's productivity which is applicable in every industrial sector. The nucleus of the approach is to develop an optimal productivity strategy in an organization by the application of a uniform static model of productivity (Q4-model), covering quantity and quality aspects and...

Lifting, carrying, pushing and pulling at work are assumed to be related to increased risks of musculoskeletal injury, mainly in the low back and shoulder region. The implementation of products to reduce the physical load in heavy work is a well-known strategy to attack this problem. The success of these products depends not only on the product...

A comparative, experimental study with repeated measures has been conducted to evaluate the effect of the use of speech recognition on working postures, productivity and the perception of user friendliness. Fifteen subjects performed a standardised task, first with keyboard and mouse and, after a six week training period, with speech recognition...

To study the effects of a tactile feedback signal in a computer mouse on reduction of hovering behaviour and consequently on changes in muscle load, productivity, comfort and user friendliness, a comparative, experimental study with repeated measures was conducted. Fifteen subjects performed five trials with different mouse actions and a...

The Individual Work Performance Questionnaire (IWPQ): internal consistency, construct validity, and norm scores Measuring individual work performance, defined as “behaviors or actions of employees that are relevant to the goals of the organization”, is challenging. So far, there was no suitable questionnaire to measure individual work...

Ergonomics sometimes has a negative connotation, as it is seen to be connected to illness or guidelines that limit innovations. This paper is focused on the positive aspects of ergonomics in improvement of the working environment. It consists of a part that studies the literature on success factors in the process towards higher productivity and...

Introduction Productivity loss is an increasing problem in an aging working population that is decreasing in numbers. The aim of this study is to identify work-related and health-related characteristics associated with productivity loss, due to either sickness absence or reduced performance at work. Methods In this cross-sectional study, data of...

The experiences of four companies are studied in a research project for the Dutch Ministry of Social Affairs and Employment. Companies producing jackets and trousers, industrial clothing, domestic textiles and jeans were covered by the project. Structural changes made by the companies are noted and the effect on the quality of work and quality...

We present guidelines for the configuration of industrial scale chromatographic separationof small molecules. We compared the performance of different axial packed beds, chan-neled monoliths and a continuous monolith assuming silica as base material. The calculatedmass transfer rates were used to calculate the height of a theoretical plate (HETP...

Inherent Safety is generally recognised as an important concept in the design of chemical plants. It is, however, often regarded as the sole province of engineers. Inspired by the successful development in the last decade from cleaner technology towards Cleaner Production, we explored in this research the feasibility of what we call Inherently...

In the current study, the relationship between objective measurements and subjective experienced comfort and discomfort in using handsaws was examined. Twelve carpenters evaluated five different handsaws. Objective measures of contact pressure (average pressure, pressure area and pressure-time (P-t) integral) in static and dynamic conditions,...

The aim of this study was to determine the effect of a tactile feedback signal on hovering behaviour, productivity, usability and comfort after 1 week of using an experimental mouse. In a randomized controlled trial, a regular computer mouse was compared to a new developed mouse with a tactile, vibrating feedback signal to prevent unnecessary...

We present a semianalytic method for modeling the productivity testing of vertical, horizontal, slanted, or multilateral wells. The method is applicable to both oil and gas reservoirs and automatically accounts for well interference. The use of analytic expressions ensures that short-time transient behavior and long-time semisteady-state...

High-end manufacturing systems are cyber-physical systems where productivity depends on the close cooperation of mechanical (physical) and scheduling (cyber) aspects. Mechanical and control constraints impose minimal and maximal time differences between events in the product flow. Sequence-dependent constraints are used by a scheduler to...

Early cost-benefit analysis of ergonomic interventions in manufacturing is in the interest of the production management and the ergonomics specialist. Because of the variety of factors and the complexity to quantify these factors, this task is not an easy one. In this article we present a case study that illustrates that the economic benefits of...

Current assembly enterprises are under a lot of pressure, as they are faced with increasing volume demands and product variations, needs for shorter delivery times and cost reduction. This pressure is likely to increase the pressure on individual workers. In many small to medium-sized enterprises (SMEs), we observe that traditional assembly...

Given a robotic manipulation task, decision on which robotic configuration (robotic system and necessary peripherals, including assistant tools, sensor systems, and so on.) to use and evaluating performance of the solution remains as an open, challenging but a meaningful problem. This work attempts to address this problem by defining the concept...
