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

There exists four main problems which are as follows: 1. Management thought is not advanced, and there is short of systematic plan. 2. Technical measures are backward, and work starting point is not high. 3. The level of personnel is low, and the development is restricted. 4. The contents of equipment are not good enough, and the funds of construction are insufficient. This paper gives the proposals on how to construct and develop equipment in colleges and universities in the future and describes the objective of the struggle, the channels to realize this objective, and the three problems to be noticed which are: 1. Adhere to integration of theory with practice. 2. Work in coordination with each other in all aspects. 3. Ensure the scientific decision. The paper also discusses some other specific problems such as management decision making, purchase of equipment, use of equipment, maintenance, modification, renewal of equipment, computerized management, etc..展开更多

It is necessary to establish a new mode for the management of university-owned equipment. Such a mode consists of both technical management and economic management. To this end, the utilization of devices and equipment in the First Military Medical University is investigated qualitatively and quantitatively. The criterion-integrated index for the utilization of equipment is proposed for the first time. By using this criterion, together with such criteria as 'quality index', 'idleness index', and 'average usage index' the utilization and management of each class of equipment are described quantitatively.展开更多

At the critical point, the number of clusters, whose enclosed area is greater than A, is proportional to A-1 with a proportionality constant C. We confirm numerically that C is universal, and its value agrees well with the predictions based on the Coulomb gas method.展开更多
