The Factory of the Future
A brief history of aircraft production techniques is given. A flexible machining cell is then described. It is a computer controlled system capable of performing 4-axis machining part cleaning, dimensional inspection and materials handling functions in an unmanned environment. The cell was designed to: allow processing of similar and dissimilar parts in random order without disrupting production; allow serial (one-shipset-at-a-time) manufacturing; reduce work-in-process inventory; maximize machine utilization through remote set-up; maximize throughput and minimize labor
Widening the wage gap: the skill premium and technology
Our final article looks at the difference in wages between high-skill workers (such as those who might work in biotech) and low-skill workers. This skill premium has increased dramatically over the past 30 years. Although economists are still debating the causes of this increase, it seems likely that skill-biased technical change has played a large role. As companies have invested in new technologies, demand for workers who can use them has surged. In "Widening the Wage Gap: The Skill Premium and Technology," Keith Sill reviews the literature and tells us why some theories fall flat and why technology seems to be the key to the widening wage gap.Wages ; Technology ; Productivity
Feasibility study of an Integrated Program for Aerospace vehicle Design (IPAD) Volume 7: IPAD benefits and impact
The potential benefits, impact and spinoff of IPAD technology are described. The benefits are projected from a flowtime and labor cost analysis of the design process and a study of the flowtime and labor cost savings being experienced with existing integrated systems. Benefits in terms of designer productivity, company effectiveness, and IPAD as a national resource are developed. A description is given of the potential impact of information handling as an IPAD technology, upon task and organization structure and people who use IPAD. Spinoff of IPAD technology to nonaerospace industries is discussed. The results of a personal survey made of aerospace, nonaerospace, government and university sources are given
Developments in the Safety Science Domain and in Safety Management From the 1970s Till the 1979 Near Disaster at Three Mile Island
Objective: What has been the influence of general management schools and safety research into causes of accidents and disasters on managing safety from 1970 till 1979?
Method: The study was limited to original articles and documents, written in English or Dutch from the period under concern. For the Netherlands, the professional journal De Veiligheid (Safety) has been consulted.
Results and conclusions: Dominant management approaches started with 1) the classical management starting from the 19th century, with scientific management from the start of the 20st century as a main component. During the interwar period 2) behavioural management started, based on behaviourism, followed by 3) quantitative management from the Second World War onwards. After the war 4) modern management became important. A company was seen as an open system, interacting with an external environment with external stakeholders. These schools management were not exclusive, but have existed in the period together.
Early 20th century, the U.S. 'Safety First' movement was the starting point of this knowledge development on managing safety, with cost reduction and production efficiency as key drivers. Psychological models and metaphors explained accidents from ‘unsafe acts’. And safety was managed with training and selection of reckless workers, all in line with scientific management. Supported by behavioural management, this approach remained dominant for many years, even long after World War II.
Influenced by quantitative management, potential and actual disasters after the war led to two approaches; loss prevention (up-scaling process industry) and reliability engineering (inherently dangerous processes in the aerospace and nuclear industries). The distinction between process safety and occupational safety became clear after the war, and the two developed into relatively independent domains.
In occupational safety in the 1970s human errors thought to be symptoms of mismanagement. The term ‘safety management’ was introduced in scientific safety literature as well as concepts as loose, and tightly coupled processes, organizational culture, incubation of a disaster and mechanisms blinding organizations for portents of disaster scenarios. Loss prevention remained technically oriented. Till 1979 there was no clear relation with safety management. Reliability engineering, based on systems theory did have that relation with the MORT technique as a management audit. The Netherlands mainly followed Anglo-Saxon developments. Late 1970s, following international safety symposia in The Hague and Delft, independent research started in The Netherland
