我系下放师生通过调查、研究、討論,找到了一个寻求麦場“最优位置”的方法。运用这个方法設置麦場,可以大大节約麦收时期的运输劳力,促使麦收任务胜利完成。下面介紹方法及其理論証明。一、不閉合的情况为了敘述方便,我們作如下定义: 不閉合线路图:所有麦地及其互相連通的道路所繪成的图,且图中任意二点有且仅有一条路連接着它們。端点:在上述图中的某点,若不存在图中其他两个点的連通道路通过它,那么就叫它是端点。最优位置:若把所有产麦点麦量全都集中到某个点上,而所用吨公里数最小,則称这个点为最优位置。 1.最优位置选定法:我們把麦地看作点,按其分布及連通着它們的道路的情况繪制成(不閉的)线路图。以符号“○”表示麦地,不带圈的数字表示产量,带圈的数字表示麦地的編号。簡单地說,这个方法是把小的 The teachers and students of my department have found a way to seek the “optimal position” of the wheat field through investigation, research and discussion. Using this method to set up a wheat field can greatly save the transport labor during the harvest period and promote the successful completion of the wheat harvest task. The following describes the method and its theoretical proof. First, the situation is not closed For the sake of narrative convenience, we make the following definition: Unclosed circuit diagram: all the maps of wheat and its connected roads, and any two points in the map there is only one road connecting them . Endpoint: At some point in the above diagram, if there are no other two roads in the map passing through it, then it is called the endpoint. Optimal location: If all the wheat yields are concentrated at a certain point and the number of tons/km used is the smallest, this point is called the optimal location. 1. Optimal Location Selection Method: We consider the wheat land as a point, and draw (non-closed) road maps according to their distribution and the conditions of their roads. The symbol “○” indicates the wheat field, the uncirculated number indicates the yield, and the circled number indicates the number of the wheat field. Simply put, this method is small
