The principles for setting up an index system have been analyzed and the index system has been set up according to projects of construction. Models for multi-level fuzzy comprehensive appraisal have been offered and relative calculation steps have been given according to project instances.展开更多

In this sense, this paper presents a new way to the appraisal of the non traditional mineral resources.展开更多

In almost every industry, employeeperformance appraisal is done manually which may lead to favoritisms. This paperproposes a framework to perform automatic employee performance appraisal based ondata sensed from IoT. The framework classifies raw IoT data into three activities (Positive,Negative, Neutral), co-locates employee and activity in order to calculate employeeimplication and then performs cognitive decision making using fuzzy logic. From theexperiments carried out it is observed that automatic system has improved performance ofemployees. Also, the impact of the proposed system leads to motivation among employees.The simulation results show how fuzzy approach can be exploited to reward or penalizeemployees based on their performance.展开更多

At first we establish the principle factor set U={U_1,U_2,U_3,…,U_n}and each principle factor U is composed of many subfactors U_j={u_(j1),U_(j2),…,U_(jn)},Then we establish the weight distribution in U and U_j.The decision set has five grades,namely:very good,pretty good,critical,rather bad,very bad.Through the establishments of appraisal metrix U_j and U We can get the final conclusion. A real example is introduced to illustrate the process of appraisal.展开更多

At present, however, the feasibility of construction is focused on. Many investment profects have shown their congenital or postnatal defects sooner or later, even has brought tremendous damage to our environment and society. Therefore, the feasible evaluation on investment is the object in this paper. On the basis of the system analysis theory, this paper uses quantitative analysis and qualitative analysis to evaluate the investment projects and demonstrates the feasibility of the projects in technology economy and societty. This paper studied in detail the feasibility of technical and economic results of civil building investment. Meanwhile, it also uses the fuzzy systematic appraisal to make mathematic model to find a series of feasible an aperatiable evaluation methods. Then, it provides scientific basis for the policy makers and make the investment get results better.展开更多
文摘The application of multi-level fuzzy comprehensive appraisal on social effects of projects has been studied. The principles for setting up an index system have been analyzed and the index system has been set up according to projects of construction.
