Multi-project and multi-attribute decision making can be characterized as a process of overall coordination and optimization. Through the application analysis of decision making, the analysis process of decision making are projected on basis of targets, methods and evaluation;then with the combination of qualitative and quantitative methods and consideration of the features of exponential model, interval ergodic analysis method is proposed and finally established. The evaluation model to be structured on basis of the method gets multiple projects and attributes involved, and conducts ergodic calculation on condition of the given target criteria and certain region of each attribute so as to get the evaluation of the multiple projects accomplished. At last, a case study is provided in order to further elaborate the application of the analysis procedures of decision making and the interval ergodic analysis method in the multi-project and multi-attribute decision making.

Over the past century,ferroelectricity has offered exciting opportunities for fundamental research and device ***,most of the discovered excellent ferroelectrics are oxide materials with large band gaps,limiting their potential for optoelectronics *** using first-principles calculations we identify a new narrow-gap ferroelectric beyond oxides,i.e.,ferroelectric perovskite sulphide BaZrS_(3).Under large compressive strains,BaZrS_(3)can be stabilized into a unique supertetragonal phase with an extraordinary polarization of 67.16μC/cm^(2),which is even stronger than that of conventional oxide ***,the supertetragonal BaZrS_(3)exhibits a direct narrow band gap of 1.2 eV and excellent electronic *** on the chemical bonding analysis,we attribute the formation of supertetragonal phase to charge re-ordering in which theπbond overlap along the long〈Zr-S〉bond completely vanishes and the antibonding states of theσbond appear below the Fermi *** work provides a conceptual strategy for designing new ferroelectrics for electronic and photovoltaic applications.

In the test and evaluation of operation, the test benefits may be greatly reduced because no useful conclusions may be obtained from test data due to missing or incompleteness of test information records. Based on the characteristics of gun firing and by separating firing errors, this paper proposes an idea using for analyzing firing accuracy in case of incomplete test data records, establishes a method for analyzing chi-square distribution-based firing accuracy data, and conducts test data analysis on test data of a certain type of weapon. The effectiveness of this method is proven by analysis results which have offered effective method for conducting test data analysis.

Warfare simulation Environment for Army Weapon and Equipment systems(WSAWES) provide a tactically robust environment for simulation experiments. The science and technology on complex Land systemssimulationlaboratory has now developed a tactical communication effects federate(TCEF) integrated with Qual Net to model tactical communications systems and networks. TCEF interacts with WSAWES's CGF that creates a constructive force-on-force simulation environment where communications are modeled by the TCEF and behaviors are modeled by the CGF. As the TCEF is already being integrated into distributed experiments in ghost mode, the TCEF services effort appears to be promising in meeting the stated goals, such as analysis for the connectivity and delay.

Under the background of the system of systems(Sos) confrontation of army weapon, owing to being enclosed in the sealed fighting subsystem, and the effectiveness matrix is degrading, so the effectiveness equivalent on the varieties of the weapon in the system of systems cannot be conducted for many years as a difficult problem in the field of assessment on the effectiveness of weapon systems. The principle of multiple effectiveness equivalent aiming at expanding the traditional effectiveness equivalent theory was presented, filling in gap existing in the original theory, and satisfactorily realized the effectiveness equivalent of varieties of main weapon systems in army's weapon system of systems, which is an important breakthrough and innovation in the study on assessment of effectiveness of weapon systems, enjoying broad utilization prospect.
