Services have become an increasingly important part of the U.S. economy. This move has forced many companies to shift their focus from simply improving product manufacturing and product delivery to ...improving product service and customer satisfaction. The effective and efficient repair of a failed system or product is one important way of improving service and satisfying customers. To provide the necessary repair, managers must ensure the availability of the right service parts at the right points within the supply chain. Thus, the management of service parts is becoming increasingly important and has already grown into a nearly $700 billion a year business, representing approximately 8% of the gross domestic product of the United States. This dissertation research effort incorporates three distinct yet related research efforts, each exploring a different aspect of the evolving role of service parts inventory management in today's supply chain environment. The first effort utilizes a field-based comparison of a system approach to service parts inventory management and a traditional item-based approach to service parts inventory management. Results suggest that a system-based approach to service parts management is more effective in reducing the number, duration, and magnitude of service part related disruptions than the more traditional item-based approach. The second effort relies on a Delphi panel of service parts experts to highlight the most critical challenges of service parts management. Consensus was achieved amongst the panel members regarding the ten most critical challenges and opportunities for future research were proposed. The final effort relied on a grounded approach to identify the challenges and objectives of service parts management and resulted in the development of two descriptive models. Each model presents a broad perspective and provides a basis upon which future research can build.
According to data from the 28th annual study, increasing collaboration with key suppliers is the most important goal, followed in rank by reducing supply lead time, providing shipment visibility and ...increasing collaboration with key customers. According to respondents, it's getting more important, with those having a clear and defined digital business strategy increasing by 26%. ...what solutions will fit into your current transportation management system, warehouse management system, and enterprise resource planning system to make them more effective?

INTRODUCTION
THERE is an increasing interest in the rate of travel of spermatozoa along the hen’s oviduct and in their sites of residence. Mimura (1939), after examining the inseminated oviduct ...microscopically, reported that spermatozoa deposited in the uterus of an empty oviduct reached the infundibulum in 26 minutes. In another paper, Mimura (1941) found that for 2 to 4 hours after intravaginal insemination, spermatozoa had not passed through the uterus. Allen and Grigg (1957), using P32-labeled spermatozoa, reported that 0.07% of spermatozoa inseminated reached the infundibulum in 15 minutes and that 1.3% were found there after 1 hour. Saeki et al. (1963) reported that at 5 hours, 81.5% of the total activity of radioactive spermatozoa was present in the vagina; and at 24 hours, the activity was 23% in the same region. The infundibulum showed 4.8% of the radioactivity at 5 hours; and 58.7% at 24 hours.

INTRODUCTION
The uptake of phosphorus-32 by whole semen and its various fractions has been a subject of interest to several workers. Patrick et al. (1962) injected New Hampshire cocks with a series ...of seven injections of 50μc. of phosphorus-32 each. They reported that the intact spermatozoa had increasing levels of radioactivity until a maximum level was reached at 28 days from the time of the initial injection. Patrick et al. (1965) reported on another experiment in which New Hampshire cocks were each administered 200 μc.of phosphorus-32 in a single injection. They discovered that the spermatozoa, semen, DNA and the protein increased in levels of radioactivity until a peak level was reached at 26 days of spermatozoa, semen and DNA, while the protein fraction of the spermatozoa exhibited a peak at 16 days. After such times as the peaks were reached, all the fractions began to decline in radioactivity. Saeki et…
