Manufacturers of manually assembled products are more and more forced to improve the flow of assembly orders together with a more efficient employment, in order to meet increasing demands on short delivery times, high product variety, good quality and low manufacturing costs. At the same time, the human factor is increasingly important, for a...

A participatory and integrative approach was developed and applied to im­prove the productivity and ergonomics in assembly companies. Main ele­ments of the approach are the active participation of the company and the integration of two disciplines: assembly engineering and ergonomics. The aims were the analysis of bottlenecks of the...

Due to fluctuations on the market, manufacturing of many product variations, and wish for fine-tuning between production and assembly a fan and motor manufacturing company wanted to improve their assembly line. The aims were efficient flow and human centered assembly in the new product line. Therefore an integral participatory approach of...

The rhythm in assembly, defined as the repetitive pattern of actions in time, is increasingly recognized as a crucial factor in assembly. Rhythm includes aspects like cycle time, action variation, work content and work rest schemes, and it affects productivity, quality, worker's motivation and worker's health. By the organization of the assembly...

This paper presents a new, semi-analytical method for calculation of the productivity of vertical, horizontal or multilateral wells draining either gas or oil reservoirs. Well interference effects and the presence of natural or induced fractures are accounted for. The method is based on an earlier derived productivity prediction tool in which...

The effects of two measures to increase the volume flexibility, namely the introduction of an alternating pause scheme and the elongation of the working day, were evaluated in two manufacturing companies. Both measures led to an increase in volume output of about 16% at relatively low costs. The local discomfort in the neck and shoulder region...

This paper presents a semi-analytical method for the modeling of productivity testing of vertical, horizontal or multilateral wells. The method, which is applicable to both oil and gas reservoirs, automatically accounts for well interference. The use of analytical expressions ensures proper handling of transient short time behavior and semi...

A pilot experiment was conducted to evaluate the effects of visual or auditory distraction in an office environment on productivity, concentration and emotion. Ten subjects performed a simple, standardized computer task in five conditions (undisturbed, 3 variations of auditory distraction and visual distraction). Results showed no effects of...

New technology will make it possible to have access to information everywhere. As a result "face to face" communication with colleagues could reduce and creativity and health could be influenced negatively. In this paper a coffee corner is changed and the effect on communication is tested by measuring the number of conversations at the coffee...

Chatter is an instability phenomenon in machining processes which limits productivity and results in inferior workpiece quality, noise and rapid tool wear. The increasing demand for productivity in the manufacturing community motivates the development of an active control strategy to shape the chatter stability boundary of manufacturing...

This introductory chapter of the publication illuminates the need for advanced infrastructure evaluation methods in developed economies, identifying fitting examples from EU member states. First, taking an historical (ex post) perspective improves the degree of realism in ex ante evaluations. Second, productivity plays a pivotal role in...

The success of shale gas exploration and production in the United States has triggered other countries around the world to look into possibilities of producing gas from different shales. As it turns out, one of the main difficulties when looking for shale gas is obtaining an in depth understanding of the shale formations and interpret where the...
