The research and development project selection process is one of the most difficult and important problems faced by management. It is typically complicated by indivisibility of projects and multiple and conflicting objectives, in addition to limitations on funding, facilities, and qualified researchers. In this paper a case example involving a high technology electrical equipment manufacturer is developed to illustrate this problem using zero—one goal programming to accommodate indivisibility of projects in addition to multiple and conflicting goals. The model presented is an attempt to provide managers with a robust tool for allocating scarce resources among research and development projects. 相似文献

Drawing upon a sample of 638 mothers aged 18 to 40, with at least some marital work experience, significant associations were found between the extent, kind, and timing of employment and a series of family formation variables. Generally lower fertility, longer first birth intervals, and earlier use of birth control were associated with the longest work durations, the highest status jobs, and work before the birth of the first child. The data failed, however, to differentiate desired family size. 相似文献

Chapter 11 can be thought of as a Ring of Gyges, protecting corporate executives from past or prospective misdeeds and missteps. The Manville Case is an example. 相似文献

Does style matter for economic writing? Several stylistic characteristics of ninety-seven AEA presidential addresses, including word length, sentence length and percent of sentences in the passive voice, were computed and used to explain citations to these economists' work. Avoidance of the passive is an old stylistic norm given by Adam Smith. Word length and sentence length serve as modern stylistic norms. Only the percent passive matters to explain citations. Perhaps not coincidentally, while writing clarity in our data set has declined over time when measured by the new norm, it has improved when measured by the old norm. 相似文献
