Interchangeable parts were a critical development in the advancement of industry and manufacturing. This paper traces its development, the factors that contributed to it, and answers the question of why did this innovation occur at the Springfield Armory.

This is an illustrative case study.

The fortunate combination of location, key people, government policy, and arms demand combined to enable the development of interchangeable parts at the Springfield Armory. Led by its Superintendent, Roswell Lee, Springfield became the epicenter for the development of this concept as skilled gunmakers captured arms making knowledge unfettered by patent protection. Lee promoted this free interchange of ideas through sharing designs and equipment, his hiring practices, and his willingness to experiment with new tools and technologies. This created a critical mass of factors that led to this important innovation occurring at the Springfield Armory.

The critical drivers of innovative activity seen at Springfield merit further investigation and research, individually and collectively to see if these findings can be used to inform policies that promote innovation.

This case study identifies factors that contributed to the development of interchangeable parts at a particular location at a particular point in time. The value of this is to identity the important interplay of factors that can spur the innovative process and lead to important technological innovation.

The purpose of this paper is to illustrate, through the example of the Springfield Armory and its role in the development of interchangeable parts, the critical role of government in establishing a cluster of organizations that evolved into an innovation ecosystem primarily located in the Connecticut River Valley in the 1800s. Using the Springfield Armory example, we use the related but largely unjoined concepts of ecosystem and networks to show that these organizational forms are effective in driving innovation.

The design uses an in-depth analysis of the role of the Springfield Armory to explicate the joining of network and ecosystem theory as an early example of the importance of governmental funding and support for innovation.

The development of interchangeable parts in the American arms industry in the 19th century transformed manufacturing worldwide. At the heart of this transformation was the network of arms makers that developed in the Connecticut River Valley as a direct result of US Government investment and support. This network of arms makers evolved into an ecosystem of mutually reinforcing relationships as machine tool manufacturers benefited from an environment of free-flowing intellectual property, information and growing governmental demand for arms. The Armory illustrates the government’s role in initiating and sustaining clusters of innovation that otherwise might not have developed as quickly.

Much of the research on the role of government in creating innovation ecosystems and organizational networks is based on modern organizations. This use of the Springfield Armory in the early 1800s broadens the knowledge on how innovation ecosystems in conjunction with networked organizations can be created by governments serving the public good.

Excess consumption of apparel is driven by the apparel industry to offer more styles at lower prices in shorter time and the consumers’ desire to change fashion. The purpose of this paper is to apply adaptable design in apparel as a sustainable design solution for excess consumption problem.

Guided by sustainable apparel design model C2CAD, two adaptable apparel prototypes for female college students were designed and developed. Focus group discussion and wear test were conducted with female college students to evaluate users’ acceptance, fit, comfort, and adaptability of the two prototypes.

Both prototypes were comfortable to wear by users with different sizes, indicating the users could wear the garment when she changed size. The adaptations and conversions were easily and enjoyably figured out by the users. The users would keep and use the adaptable apparel for a long time. The users would also buy fewer apparel if they were to own the adaptable apparel. Adaptable apparel would increase apparel utilization, eliminate the need to purchase unnecessary additional amount of clothing, and reduce excess consumption.

This research provided a pilot study on adaptable apparel design as an innovative approach to help solve excessive consumption problem. The adaptable garment prototypes would allow the fashion-forward female college student to easily change the function, fit, and style of the environmentally friendly garments.

EVERY manufacturer is constantly on the alert for methods of increasing efficiency at reduced costs. The drawing office, which is responsible either directly or indirectly for a very large proportion of the cost of an aeroplane, should receive more attention than it usually does. This article deals with a number of simple points which have proved the value of their adoption.

The purpose of this paper is to present the benefits offered by rapid prototyping (RP) models for wind‐tunnel testing as part of fourth‐year aerospace engineering student projects. Ways of overcoming some of the difficulties associated with the 3D printing technology are also discussed.

Polymer‐based RP was used to fabricate two‐aircraft models, which included stiffening metallic inserts. Testing in a subsonic‐wind tunnel was carried out and the results compared to analytic performance predictions.

Low‐cost rapid prototypes of wind‐tunnel models yielded satisfactory aerodynamic performance. The savings in acquisition cost and time allowed incorporating actual testing in the aircraft design process within the framework of a tight academic budget and schedule.

Conducting real‐wind‐tunnel testing contributes significantly to the educational experience of students; however, it had rarely been carried out when metal model fabrication was the only option. In contrast, RP facilitates an enhanced and more realistic learning experience by offering a quick and affordable means of model manufacturing.

Simple methods of reinforcing polymer‐based models were incorporated, thus presenting an inexpensive way to test and evaluate preliminary aircraft designs, in both academia and industry.

The author argues that we must stop and take a look at what our insistence on human labour as the basis of our society is doing to us, and begin to search for possible alternatives. We need the vision and the courage to aim for the highest level of technology attainable for the widest possible use in both industry and services. We need financial arrangements that will encourage people to invent themselves out of work. Our goal, the article argues, must be the reduction of human labour to the greatest extent possible, to free people for more enjoyable, creative, human activities.

The need for third‐party companies to provide computer maintenance is certain to become more widespread as end users become more knowledgeable and specific in their requirements. The strength of a third‐party maintenance company is its ability to take on responsibility for the whole installation, its contract flexibility, its pricing structures and its ability to service any make of computer. Points to look for in a reputable company are the availability of spare parts or interchangeable parts from other systems, back‐up facilities (i.e. back‐up machines) and the use of subcontracted service centres.

Remanufacturing is a process whereby value from old products is recovered by replacing and recovering used components to bring such products to a new or like-new state. Today, both original equipment manufacturers (OEMs) and third parties are engaged in remanufacturing activities, investing in many locations throughout Asia. The purpose of this paper is to examine the reasons for initiating remanufacturing activities as well as the location determinants for the remanufacturing sector in Asia.

The authors conduct a multiple case study. Triangulation is applied to gain objective views from interviewing three OEMs, one logistics firm, and three local small enterprises. Real options theory is the theoretical lens used to examine the location choice of the OEMs.

Firms engaged in remanufacturing tend to co-locate facilities with existing manufacturing facilities, and those investing in new sites for remanufacturing view the regulatory environment as the most important factor. OEMs tend to leverage on existing manufacturing facilities or third-party remanufacturers to reduce their cost of commitment when starting remanufacturing at new locations.

The sample size is still small for the generalization of the results. Further empirical study is needed to test the propositions from this paper.

This paper could assist managers and decision makers in the multinational corporations to design appropriate logistics-related solutions for remanufacturing in Asia.

The authors work contributes to the theory on remanufacturing location determinants. It shows that OEMs and third-party remanufacturers can have a collaborative relationship instead of the commonly assumed competitive one, which is currently not found in the literature.

Case studies of four important automobile firms are used to understand how the performance of both diversifying and new entrants into the automobile industry was conditioned by their pre-entry experience. Various conjectures based on the four firms are then tested using a unique data source on the pre-entry backgrounds of all entrants into the automobile industry from the commercial inception of the industry in 1895 through 1966. In addition to analyzing the types of pre-entry experiences that affected the longevity of entrants, the analysis also focuses on the conduits by which pre-entry experience influenced the performance of entrants and the extent to which pre-entry experience had enduring effects.

The paper aims to present a hands‐on activity for operations management (OM) education that simulates assembly operations common in industrial settings using polyvinyl chloride (PVC) threadable fittings utilised in water pipes as interchangeable parts for easy manual assembly.

The teaching method followed the philosophy of active learning and was applied in an action research approach; the proposed activity was tested and improved during applications in the classroom.

The applicability of the method was proven during in‐class exercises. The results were confirmed with positive feedback from the students involved in the exercises, which was obtained through a survey conducted after a set of applications.

Although the proposed activity may have several possibilities for application, this paper focuses specifically on teaching the topics of work measurement and assembly line balancing, thus limiting the generalisability of these findings to other OM techniques. Therefore, it is important that the activity is further adapted to teach other OM topics.

The activity performed with pipe fittings represents a practical exercise that contributes to reduction of the gap between theory and practice in OM education. Using simple and low cost materials, the students are involved in creating a real process from a fictional product.

This paper presents an experiential learning exercise applied using an innovative approach, using pipe fittings as interchangeable parts assembled in a production line.
