Studies of managerial variables on broiler performance and abdominal fat levelsHakimi, Ali Y. 14 September 1992 (has links)
Today's consumers have shown a greater concern in the relationship between dietary fat and human health. The demand for leaner meat is continuously on the rise. The reduction of fat deposits in the abdominal area of ready-to-cook fryers, considered a waste product in the poultry industry, has become a major opportunity for the researcher.
Experiments were conducted to evaluate the merit of managerial practices affecting abdominal fat (AF) levels in broiler chickens. Factors studied included seasons of the year, source of the commercial broiler strain crosses, stocking densities, lighting systems, types of housing, dietary salt (NaCl) 1eve1s and feed restriction.
Two housing types (open-sided and windowless) and different seasons were utilized to evaluate the influence on broiler performance and AF levels. Raising broilers from the same strain cross in an open-sided building did not affect performance and AF levels. Mean body weight (BW) were highest
in fall season (1929 g ) and lowest in summer (1735 g) (p<.05) while highest and lowest % AF revels were observed in spring and winter (2.34, and 1.42 respectively).
The comparative effect of feeding regime, (full feed, FF), 95 and 90% FF), dietary salt 1evels (0, 0.25, and 0.5% of the finisher diet), stocking densities (0.06, 0.07, and 0.09 m�� of floor space per bird) and type of housing (battery cages and litter pens) were examined on broiler performance and AF lever. Ninety % FF resulted in significantly lower body weights and AF levers compared to ad libitum feeding. At 49 days of age, mean BW of broilers fed 0.5% salt were higher (P<.05) than the group not provided with salt. Altering stocking densities and rearing in battery cages failed to show any significant improvements performance and % AF.
Lighting regime 12 h light (L): 12 h dark (D), recycled during the rearing period resulted in lower (p<.05) mean BW than continuous lighting regime (CL) when applied from 5 days of age. Broilers raised on 16L:8D after 21 days had comparable performance to CL. Lighting regime of 12L:12D, recycled in combination with increasing stocking densities from 0. 06 to 0.8 m�� floor space/broiler and intermittent righting of lL:3D in combination with the addition of 0.5% salt to the diet resulted in improved (P<.05) BW with no corresponding increases in AF levels.
Factors such as season of the year, feeding of salt, and manipulation of light (up to 8 h dark) can be used as tools in reducing % AF and overall production costs. / Graduation date: 1993

An innovative framework for implementing lean principles in product-service systemElnadi, Moustafa January 2015 (has links)
The aim of this research project is to develop an innovative framework to implement lean principles in Product-Service System (PSS) with the capability of assessing the leanness level of the services offering process. The framework comprises three implementation phases namely: assessment of the current state, developing a future state, and stabilising the new way of operations. Additionally, the framework covers the enablers, factors, and appropriate lean tools required for the successful implementation of lean practices in Product-Service System (PSS), as well as, the challenges that may obstacle the implementation process. The proposed framework has integrated an assessment model that provides a quantifiable measure of the leanness level of Product-Service System (PSS). Five main enablers and thirty three factors emerging from these main enablers deemed to be critical for the successful implementation of lean practices in Product-Service System (PSS). Moreover, a series of eight inhibitors appeared to block the implementation process. The Product-Service System leanness assessment model was developed upon three main levels, namely: enablers, criteria, and attributes. The first level contains five enablers. These enablers are supplier relationship, management leanness, workforce leanness, process excellence, and customer relationship. In the second level there are twenty one criteria such as: supplier delivery, culture of management and process optimisation. Finally, the third level consists of seventy three attributes. By using multi-grade fuzzy approach the PSS leanness index was computed and areas for further improvement were identified. A combination of research methodology approaches has been employed in this research. Firstly, an extensive literature review related to lean and PSS was conducted. Secondly, the qualitative approach and the case study were selected as an appropriate methodology for this research, using semi-structured and structured interview techniques to gather the required data from experts who are involved in lean projects in their companies. Finally, validation of the results was carried out using real life industrial case studies and experts judgment. Case studies demonstrate that the framework provides guidelines for manufacturing companies that aim to implement lean principles in Product-Service System (PSS). The framework enables manufacturing companies to better satisfy their customers’ needs through responding quickly to their changing demands; to improve the service offering process through reducing the creation of wastes and non-value added activities; and to improve competitiveness through increasing customers’ value. Additionally, the PSS leanness index is useful for improving the service offering process. The index provides manufacturing companies with a real insight into the leanness level of their service offering, as well as, it provides managers with a quantifiable measure of how lean their PSS is. The index identifies the gap between the current state and the future state and this helps in determining areas for further improvement.

Inter-Enterprise Cost-Time ProfilingRivera, Leonardo 26 September 2006 (has links)
Measuring the use of resources in a production process has been a subject under great scrutiny since more than a hundred years ago. Traditionally, costing systems and cost accounting systems have been in charge of such functions in manufacturing corporations. On the other hand, in recent years Lean Manufacturing has become a powerful and popular force for change. A premier tool for process visualization and understanding is Value Stream Mapping, and it focuses primarily in the time dimension of the processes.
However, it is clear that the interaction of cost and time is very important. This is felt in everyday occurrences, such as paying interests for credit cards, mortgages and other types of loans. It is intuitive that the longer a certain amount of money is held, the more it costs. Also, if a larger amount of money is held for one day, it will obviously cost more than holding a smaller amount of money. Therefore, cost and time, BOTH, determine the real cost of the use of money.
However, this simple perception has not been applied equally to the measurement of manufacturing processes. They usually concentrate on either cost or time, but seldom in both at the same time and their interaction. The Westinghouse corporation formalized the concepts of the Cost-Time Profile in 1993, based on work done there during several decades.
Simply put, the Cost-Time Profile measures how much money is invested in the manufacturing process of a product and for how long, creating a chart that presents the accumulated cost at every point in time (Cost-Time Profile) and measuring the area under this curve (Cost-Time Investment), and then using this quantification to measure the bottom line impact.
This research has accomplished two main things: the detailed consideration of the Cost-Time Profile (CTP) and the issues and factors that affect it, and the extension of the concepts to the new reality of Extended Enterprises. In a logical sequence, the basic concepts of CTP are defined and presented. Then, the extension of them to Inter-Enterprise environments follows.
Successive sections present how to build a CTP and the Inter-Enterprise Cost-Time Profile (IE-CTP), as well as discussing the factors that should be taken into account to bring the IE-CTP to practical applications, such as the effect of batching; the interaction with existing accounting systems; the consideration of direct cost, overhead and profit and the relationships between companies in supply networks to build IE-CTPs.
Then the issue of how to improve the results of the Cost-Time Investment (CTI) and CTP is addressed, and schedule optimization models are developed; generic improvement scenarios and lean implementation scenarios are discussed; some simulation studies are presented for cases when this tool has advantages over deterministic tools and an IE-CTP specific software tool is presented.
After learning how to improve the CTP and CTI, a discussion about how to use it and implement it is presented, and finally the summary and conclusions close this research report, identifying the contributions presented and leaving open avenues for future research. / Ph. D.

A comparative study of certain factors related to obesity and leanness in several preadolescent girlsMoore, Betty Joyce 11 May 2010 (has links)
This study is a comparison of certain factors related to leanness, obesity, and "average" weight in 12 healthy preadolescent girls of above-average intelligence and similar family backgrounds. Factors considered were anthropometric data from the subjects, possible height-weight relationships between subjects and parents, 7-day calorie intakes of the subjects, 7-day activity records and certain eating practices of the subjects and parents, and some personality components and activity interests or the subjects as measured by standardized tests.
The subjects, ranging in from eight to 10 years, were selected according to the physique appraisals of lean, heavy, and "average.” Mean weights of the lean, heavy, and “average” subjects, respectively, were 23.4 kg, 43.0 kg, and 27.8 kg. Corresponding mean percentage deviations from standard height-weight criteria were 18.7 percent underweight, 29.5 percent overweight, and within 4.9 percent of the standard. Eight additional anthropometric findings supported these physique appraisals. Calculated mean daily caloric intakes for the lean, heavy, and "average" subjects, respectively, were 2193 calories, 1925 calories, and 1761 calories. Reported activity patterns suggested that the lean subjects and their parents were the most physically active, while the heavy subjects and their parents were the least active. These findings for the subjects were supported by their scares in a standardized interest inventory.
A tendency toward obesity in the subjects studied was more related to lack of interest and participation in physical activities than to excessive caloric intake. / Master of Science

Things that are good and things that are chocolate: A cultural model of weight control as moralityMoore, Nancy Helen Vuckovic, 1956- January 1990 (has links)
The ideology of weight control as evidenced in the discourse of American adolescent girls is explored via a cognitive approach to discourse analysis, and focuses on the teasing out of cultural models through evidence in natural language. It is hypothesized that a cultural model exists which equates weight control with a moral code reflective of the Protestant ethic. The research examines how the cultural model frames experience by supplying interpretations of that experience, and how it influences behavior by supplying goals for action. The cognitive salience of the model within the belief system of the individual regulates the degree of influence the model has on behavior. Four levels of influence are proposed, ranging from cultural cliche to motivation of disordered eating. The predominant influence is found to be as an occasional guide to weight controlling action or discourse about such action.
