The justification of flexible manufacturing systems (FMS) is a topic that has gained a lot of attention due to the strategic effect it has on the competitive stature of industrial firms. The decision to convert to FMS should follow a pattern of feasibility assessments, cost/benefit analysis where consideration of issues such as increased quality, productivity and capability as well as tangible benefits takes place. Difficulties, however, arise in the modeling of the behavior of the proposed FMS. This paper introduces the design of a decision support framework that aids the strategic planner in simulating the performance of proposed FMS and in determining the parameters that affect the costs and benefits, tangible and intangible, of such a system. The decision support system (DSS) allows the user to use subjective evaluations of benefits accruing from intangible considerations of new product design, faster turnaround on design-to-market cycles and new marketing strategies in fragmented markets. The DSS enhances the examination of issues such as changing demand, varied tasks and routings, job and machine flexibility, etc. which affect costs and benefits. It performs these important functions by allowing for the development of scenarios that aid in the evaluation of the effect of the conversion from non-flexible to flexible manufacturing on the organization's financial position. 相似文献

Immigrants’ ages and the structure of stationary populations with below-replacement fertility 总被引:1,自引:0,他引:1
Carl P. Schmertmann 《Demography》1992,29(4):595-612
A sustained regime of low fertility plus immigration yields an unusual kind of stationary population. The author demonstrates that all stationary populations have a common structure, and that the familiar replacement-level fertility population is the youngest among the many stationary populations corresponding to a particular life table. This finding has important consequences for policy because although fertility increase and immigration are equally effective at halting population decline, immigration is inferior as a means of rejuvenating low-fertility populations. In fact, an immigration-based policy could make a low-fertility population older rather than younger. The paper includes examples using U.S. and West German vital rates. 相似文献

Mexican cinema, one of the most active in Latin America, dates from 1896, while sound film recently celebrated its fiftieth anniversary there. Among the many prominent Mexican cineasts whose films form a repertoire of solid artistic achievement is Alejandro Galindo. Like many fellow-filmmakers, directors and actors, Galindo did his aoprenticeship in Hollywood, returning to Mexico in 1930 to become one of Mexico's most creative and dynamic practitioners of cinematic art. Carl Mora highlights his accomplishments while placing him in the perspective of the development of the Mexican film industry. For example, during World War II the industry boomed because of the demand in Latin America for authentic Latin American cinema. With this impetus, Mexico (and Alejandro Galindo) enjoyed a decade of growth and popularity. Unlike most other Mexican cineasts, Galindo dealt with the dislocations that a rapidly changing economy and increased urbanization brought to both the workers and the middle class. Mora discusses several of his most important films, amply demonstrating the impact Galindo believed that cinema could have on society. He left a legacy that is admired today by critics and filmmakers. 相似文献

This paper examines contacts that Swedish physically abused children have with the Department of Social Services (DSS) 4 years after a physical abuse incident has been reported to the police. The children’s files have been investigated in an effort to evaluate which child and parent characteristics led DSS to make interventions for the 69 children still in need of assistance, 4 years after the original abuse incident. Intervention by the DSS prior to the reported abuse incident increased the odds 18 times that a child would still receive interventions 4 years after the incident, and the presence of a mentally ill mother increased the odds 11 times. 相似文献

The purpose of this study was to conduct a cost-benefit analysis of three Drug Court programs in Kentucky for two groups of Drug Court participants: program graduates and program terminators. The economic benefits of the Drug Court programs were estimated relative to a comparison group of individuals who were assessed for the Drug Court programs, but did not enter the programs. This study highlights important factors in estimating the costs and the economic benefits of a Drug Court program. Results indicated that, particularly for graduates, Drug Court involvement was associated with reductions in incarceration, mental health services, and legal costs, as well as increases in earnings and child support payments. Net benefits and benefit–cost ratios for each program are presented and policy implications are discussed. 相似文献

Adolescence for the Puerto Rican girl in the United States constitutes a phase of life in which developmental tasks are strained by the demands of her family and exposure to two cultures. This stress renders her adaptive potentials vulnerable to dysfunction. The authors describe the Puerto Rican family, the girl's socialization, the stress of living in dual cultures, and implications for behavioral problems. These factors are integrated to help the practitioner design culturally sensitive interventions.Carl Bryant is an Adjunct Assistant Professor Hunter College School of Social Work and is also in private practice. 相似文献
