粮食生命线工程的系统构造与分析

Food Lifeline Engineering System Construction and Analysis

粮食生命线是一个复杂的适应系统,由基本的过程活动和辅助的支撑活动构成。基本的活动包括了从粮食生产、储备直到消费的全过程,形象地说是从田间到餐桌的全过程。围绕着这一基本过程,还有一些重要的辅助和支撑活动,如政策、技术、信息等,这些因素彼此复合,形成富有活力的＂龙体＂结构。该结构具有自己的长度、宽度、厚度和色度,并在环境要素的变化中能够主动作出反应,自动调节自己的行为,实现系统优化,各个环节的功能相互配合,形成诸如动力、保健、发展演化等多种机制,从而保证整个系统的整体、协调、高效、健康运转。

Food Lifeline is a complex adaptive system,whose basic process including activities and supporting activities,which compound to form a dynamic ＂dragon＂ structure.This structure has its own length,width,thickness and color,which can change with environmental factors and initiate a response,automatically adjust their behavior to achieve system optimization,to ensure the whole system being coordination,efficiency,and healthy functioning.
