A genetic algorithm for determining optimal replenishment cycles to minimize maximum warehouse space requirements

In a supply chain, it is an important issue for logistic managers to offset the replenishment cycles of multiple products sharing a warehouse so as to minimize the maximum warehouse space requirement (MWSR). Most of the studies in the literature assume that warehouses replenish at the beginning of some basic planning period. In this paper, we relax this assumption by allowing the warehouse to replenish at any time. In order to solve this problem, we conduct theoretical analysis based on Fourier series and Fourier transforms and propose a procedure that is used to calculate MWSR efficiently for any given replenishment schedule. Then, we employ this procedure in a genetic algorithm (GA) to search for the optimal replenishment schedule. Using randomly generated instances, we show that the proposed GA significantly outperforms a previously published heuristic.

鸱鸮与凤凰--中国文学中的一组对立意象

在中国古代文学中,凤凰与鸱鹗常常被组合在同一个语言情境中,而其寓意却一正一反,完全相左.凤凰象征着神圣、高洁、美善、君子、祥瑞,鸱鹗象征着凡俗、卑污、丑恶、小人、凶灾.这对矛盾意象,充分体现了古人尊凤贬鹗、好凤恶鹗的民俗心态,也体现了一种二元对立的普遍心理模式.

Peep show establishments, police activity, public place, and time: a study of secondary effects in San Diego, California

An empirical study was undertaken in San Diego, California, to test assumptions made by the government and by conservative religious policy advocates that there is a greater incidence of crime in the vicinity of peep show establishments. We asked two questions: (a) Is criminal activity in San Diego particularly acute at peep show establishments compared to surrounding control locations? and (b) Is criminal activity in San Diego disproportionately greater at or near peep show establishments between the hours of 2 a.m. and 6 a.m. compared to other times of the day? The levels of crime activity and the expenditure of police resources were examined by measuring the number of calls-for-service (CFSs) to the police within a 1,000-ft. area on either side of the peep show establishments and comparably-sized control areas beyond the immediate 1,000-foot area. A more focused late-night (2 a.m. to 6 a.m.) analysis was also undertaken. The results showed no reliable evidence of differences in crime levels between the control and test areas, nor was there any evidence of disproportionately greater amounts of crime within the 2 a.m. to 6 a.m. time period in the areas surrounding the peep show establishments. We concluded that San Diego does not have a problem with crime at the peep show establishments generally, nor is there a heightened problem with crime during the 2 a.m. to 6 a.m. period. We discuss the implications of assuming that peep show establishments are associated with negative effects in the community and the possibility of viewpoint discrimination against sex communication.

农业资源与农业可持续发展

《中国21世纪议程——中国21世纪的环境与发展白皮书》中指出,农业是中国国民经济的基础,农业可持续发展是中国可持续发展的根本保证和领先领域,农业可持续发展就是要使农业具有长期持续发展的能力。而农业资源如土地、水资源、劳动力和资金等作为农业生产的物质基础和条件,直接影响着农业发展和社会发展,应得到更加广泛的重视。本文从农业资源角度来探讨中国的农业可持续发展。
