Model building in physical, statistical, simulation or other form, is making an increasing contribution to the problem solving methodology in economics, industry, government, and technological development (1). More specifically, in the present context, simulation models can offer a distinctive and valuable contribution to the understanding by management of complex business systems, interactions and environment and indicate ways toward improvement, financial and otherwise (2). The advent of powerful computers in the last few years is the decisive factor which has decided the means of realizing the full potential of simulation models, hitherto unattainable because of the vast amount of data processing and calculation required. The purpose of this article is to indicate the approach to and scope of a computerized simulation model for long term production strategy decision making (3). While the model relates to the system and data of a specific production unit, manufacturing electronic components, the principles are widely applicable in any size and type of company. It is not a specifically large company technique.  相似文献

Board approval of an operating budget, a traditional exercise of board authority, can trivialize board leadership and stultify managerial prerogatives. Considered within a new governance paradigm, conventional budget approval is not only unnecessary, but dysfunctional. This article argues that boards should proactively establish policy for financial planning and then require administrative budgeting throughout the year to meet the policy criteria. The result is that boards stay focused on the bigger issues, particularly program priorities and goals, leaving managers the authority to create and adjust budgets within policy boundaries.  相似文献

The association between sociodemographic, demographic, and attitudinal measures and the timing or tempo of marital dissolution over a 14-year time span is examined. Separation is considered equivalent to divorce. Early and late divorce are differentiated by whether the event occurred before or after the average number of years married prior to divorce. Data were obtained on husbands and wives within childbearing years (up to 39 years) in the 1st years of the 1st marriage. A random stratified sample of 610 couples was drawn from records of marriages in a midwestern county between 1972-77. Reinterviews were conducted on 544 couples in April 1985. socioeconomic variables included educational attainment, occupational prestige, wife's employment status, wife's future work plans, husband's attitude to wife's future work plans, total family income, and level of satisfaction with current financial status. Demographic variables are age at marriage, number of children in 1985, marital duration, and desired family size. Attitudinal items were religiosity and gender role orientations (traditionalism, modernism, egalitarianism). Exposure to divorce was not equitably distributed for the 108 who divorced, but this was not statistically significant. The results indicate that those divorced earlier were wives who worked outside the home, worked at more prestigious jobs, planned to be employed throughout married life, and whose father had a higher level of educational attainment. This finding is not consistent with prior research which has shown that favorable socioeconomic conditions lower the probability of divorce. The timing of divorce was affected by the presence of children. Those married at younger ages divorced earlier and couples with children delayed divorcing longer than couples without children. These findings were consistent with earlier research. Catholic wives delayed divorce longer than non-Catholic wives. Males lower in sexual satisfaction divorced earlier. Divorce was postponed longer for husbands with traditional values and wives who had higher scores on egalitarianism. Wives with scores on modernism had earlier divorces than wives scoring lower on modernism. The tempo of divorce was in multiple classification analysis predicted best by wife's employment status and number of children. Cross-classification was not possible.  相似文献

Much has been written, both in benefit-related journals and in the general press, about the recent statement, FAS 106, issued by the Financial Accounting Standards Board (FASB). This statement requires most employers to begin accounting for retiree health care benefit costs for active employees as well as current retirees, creating a significant negative financial impact. Most of the attention has been focused on getting the numbers that will tell the extent of the impact resulting from FAS 106. The next step has been to review retiree medical coverage to see how the affected companies can change it to reduce their liability. Although the urge is strong to adopt a quick-fix solution, employers can greatly benefit by reviewing their benefit philosophies and making plan decisions that make sense for them. This article discusses key questions that can help focus the issue on company philosophies and lays out a framework for determining suitable plan designs that can also help companies manage the retiree medical liability.  相似文献
