国内竞争情报可靠性评估研究综述

针对国内近些年在竞争情报可靠性评估研究方面的成果从定性和定量两方面进行了综述,竞争情报的定性评价方法主要有信息源评价、信息本身评价、实践标准、情报评级,定量评价指标主要有稳定性指标、绝对误差和相对误差、信息可靠性系数,并对每种评价方法和评价指标进行了介绍,认为每种评价方法都有其局限性,评价竞争情报的可靠性应同时采用多种分析方法从多点入手进行。

A general planner for agro-ecosystem models

In agro-ecosystem simulation models involving a farm, management is usually controlled through some combination of calendar- and logic-based rules. This approach has been quite successful but despite their apparent naturalness and simplicity, rules do present some difficulties in use and implementation. Even relatively simple rule sets can become quite large and difficult to follow, and they are based on the current state of the system rather than anticipating the likely future state of the system. Systems based on alternative approaches may have the capability to improve on the performance of rule-based systems and here we describe the implementation of such an alternative, called the general planner for agro-ecosystem models (GPAM), and discuss how the GPAM makes decisions in the presence of complex interactions.The GPAM works by constructing a decision tree of all possible decisions up to some defined point in the future, assessing which pathway through the decision tree leads to the best outcome, and then passing set of decisions defining that pathway to the simulation model to implement. To test its capabilities, the GPAM was instructed to control a grazing rotation in a very simple agro-ecosystem model. Tests were conducted to examine the reaction of the GPAM's performance to a range of parameters, including how far forward in time it looked when optimising the rotation length, how often it revised the rotation length plan, and how often it was allowed to change the rotation length. In all of these tests the GPAM reacted as expected and, without being provided with any prior knowledge, decided to implement the long winter rotation lengths normally used by farm managers in year-round grazing systems to make best use of limited pasture. The highest levels of animal production were obtained when the GPAM was able to make swift changes in the rotation length, when it looked further into the future when optimising the rotation length, and when it re-planned often.Initial testing indicated that the GPAM showed promise as a new way of emulating the manager in simulation models. More work is needed to assess the performance and potential of the GPAM when it is provided with imperfect or biased information on the likely future states and to allow the GPAM to manage multi-objective systems, such as when balancing production and environmental goals.
