The purpose of this paper is to derive a procedure to evaluate a group of alternatives or units considered as systems where a certain transformation process consums heteregenous input attributes or items (to be understood in a broad sense including effort that must be done, a negative impact, consumable resources, ...) to produce or deliver heteregenous output items (including subjective satisfaction, tangible products, beneficial impact. ...). In general, many actors with, different points of view as well as different information sources more or less reliable will be involved in the evaluation process. The evaluation context we consider here consists in stakeholders (decission makers, experts, users. ...) that give then- opinion regarding the impact of each item with, regard to the evaluation goal ; the information or data (values of items for different alternatives) about items are collected from or supplied by different more or less reliable information or data sources (news papers, magazines, web. agencies and consulting cabinets, experts. ...). The established model aims to integrate the interactions between these different components (stakeholders, items. information sources and alternatives) and consists bassically for each alternative or unit in computing two measures: an aggregated measure known as the selectability at the output of the system and an aggregated measure at the input known as the rejectability in the framework of satisficing game theory. The derivation of these measures is carried up by a pairwise comparison process using the analytic network process (ANP) approach, an extension of the well known analytic hierarchy process (AHP), that allows to take into account complex interactions of evaluation process components such as dependency and feedback.

In the paper authors presented concept of evaluation of complex systems such as logistic companies which operate in competitive environment. Authors also highlighted the importance of the evaluation problem in operational activity, particularly in the properly prepared procedures to be followed, consisted of several stages adapted to currently conducted research. Properly executed evaluation of companies enables customers to take right decisions on contracting services and stimulate the development of those companies. It should be noted that the proposed algorithmic model of assessment may be particularly useful for assessment of complex logistics systems. Characteristics of the respective phases developed procedure allowed to indicate that it is important to select of appropriate criteria and evaluation methods. It was pointed out that particularly useful for assessing of logistics companies are multi-criteria analysis methods, because they allow to examine objects in a holistic manner, taking into consideration various aspects of activities such organizations. For the practical realization of assessment of logistics companies there was proposed Bellinger method, which contains quite transparent procedures. The results obtained from that method are consistent with those carried out by means of other, more complex multi-criteria methods. Also there was presented the problem of selection of weighted factors for the criteria in the context of their impact on the end result of evaluation. It was pointed out that the choice of an appropriate procedure for determining weights depends on the nature of the evaluated problem and form of criteria.

Major crises such as greenhouse effect and resource depletion remind people that environmental protection is imminent. However, the economic growth is always accompanied by the destruction of the environment, so the development of green industry economy is very necessary for the balance between the two. However, many of today’s green industry economic development is still in the theoretical stage, and there are no substantive measures. Therefore, this paper aims to build a reasonable development evaluation model for the green industry economy, and use the results of the model to explore the sustainable development of the green industry economy. In view of this, in the stage of proposing the model, this paper refers to a large number of literature and field investigation, and selects 30 suitable evaluation indexes. The experimental results of the green industrial economy in Sichuan Province with the designed model show that the comprehensive evaluation index of green economic development has increased steadily. It reached 0.8255 in 2016, which is in line with the actual situation. This shows that the model in this paper has a good fitting effect, and can provide guidance for the economic development model and effective path of green industry.

With the development of the economy, people’s living standards are getting higher and higher. People will look for ways to relax after busy work, and rural tourism is a slow-paced life. The purpose of this paper is to analyse the evaluation system of rural sustainable tourism land based on ecosystem service value. In this paper, an evaluation model based on AHP and association rules is proposed, and the two methods are described in detail. The experimental results of this paper show that the number of tourists has increased from 12 % in 2014 to 24.9 % in 2020, and the growth rate of tourism revenue has increased from 24 % in 2014 to 30 % in 2020. Rural tourism is an important part of tourism and an important force to implement the strategy of rural revitalisation. It plays an important role in accelerating the modernisation of agriculture and rural areas, the integrated development of urban and rural areas, and poverty alleviation in poor areas. The number of farm stays has increased from 1.9 million in 2014 to 3.25 million in 2020. It can be seen that with the growth of time, the rapid development of the economy, and increasing people who love to travel, this has led to changes in the utilisation rate of rural land. Therefore, the research on the evaluation system of rural sustainable tourism land based on ecosystem service value is very meaningful.
