Operations research is the study of factors that can be controlled by program administrators. Among such factors is the frequency of performing program activities. The present experiment, conducted in Lima, Peru during 1985-86, tested the impact of holding family planning post sessions once per month, twice per month, and weekly. Frequency was shown to have a major impact on program outputs, costs, and cost-effectiveness. Depending on the indicator, sessions held twice per month produced between 1.5 and 2.1 times the output of those conducted once per month. Weekly sessions produced between 1.3 and 1.6 times the output of those held twice per month. At an output level of nearly 11,200 visits per year, twice-per-month sessions were estimated to be 7-38 percent more cost-effective, depending on the indicator, than once-per-month sessions, and 6-28 percent more cost-effective than weekly sessions.
运筹学是对项目管理者能够控制的因素进行的研究。这些因素包括开展项目活动的频率。1985年至1986年在秘鲁利马进行的本次实验，测试了每月举办一次、每月举办两次和每周举办一次计划生育后续会议的影响。结果表明，频率对项目产出、成本和成本效益有重大影响。根据指标不同，每月举办两次会议的产出是每月举办一次会议产出的1.5至2.1倍。每周举办会议的产出是每月举办两次会议产出的1.3至1.6倍。在每年近11200次就诊的产出水平下，根据指标不同，每月举办两次会议的成本效益比每月举办一次会议高7%至38%，比每周举办会议高6%至28%。
