Existing“evaluation indicators”are selected and combined to build a model to support the optimization of shale gas horizontal *** this end,different“weighting methods”,including AHP and the so-called entropy method,are combined in the frame of the game *** a relevant test case for the implementation of the model,it is shown that the horizontal section of the considered well is in the middle sweet spot area with good physical properties and fracturing *** comparison with the FSI(flow scanner Image)gas production profile,the new model seems to display better abilities for the optimization of horizontal wells.

In order to scientifically and reasonably select the field operation machinery in the wheat-maize double cropping system,first,the selection evaluation index system was constructed through the existing national standards and industry *** the selection evaluation model was established based on the improved fuzzy comprehensive evaluation *** the method of subjective weight and objective weight was used to overcome the drawbacks of the previous single weighting method that could not take into account the subject and object information of each indicator,and the weight value of each index was obtained in the evaluation ***,the tillage process was used as an example,the field experiment was carried out to obtain the evaluation index value,and the model of selection evaluation was *** selection results of moldboard plough and rotary cultivator were as follows:the order of the comprehensive evaluation results of the moldboard plough results was ranked from high to low as 1LFK-435(IIM),1LFK-535(IM),1LF-342(IIIM),1LFT-445(IVM),1LFT-545(VM),and the best machine type of the moldboard plough was IIM;the order of the comprehensive evaluation results of the rotary cultivator was ranked from high to low as 1GQKGN-240(IIIR),1GKNSM-250(IVR),1GKN-230K(IR),1GKN-250K(IIR),1GQKGN-220(VR),and the optimal model of the rotary cultivator was *** experimental results showed that the results obtained by the evaluation model were in agreement with the local actual *** evaluation model will provide a scientific method for the selection of wheat and maize double cropping field operation machinery.

System evaluation is the later stage work of system analysis and also the earlier stage work of decision analysis and it’s in the "hub" status of system engineering theory and *** evaluation has wide application value for application of system engineering theory and *** supply chain trust is very important for the performance of supply chain *** order to effectively measure the level of supply chain trust,the paper constructs an evaluation index system for complex system of supply chain *** then subjective weight based on Fuzzy Analytic Hierarchy Process(FAHP)and objective weight based on entropy weight are integrated by the least square of deviations which is proved the most effective combination method,thus a new model of comprehensive evaluation is offered for the level of supply chain *** method makes full use of useful evaluation information and avoids the limitation of single evaluation *** example was used to reveal the effectiveness and reliability of the combination evaluation method.

＜正＞A new combination assigning weight approach based on decision maker’s preference and projection pursuit clustering model is proposed to overcome the shortages of subjective and objective assigning weight *** multidimensional data are easily transformed into low dimensional space and the structural feature of multidimensional data can be revealed through applying projection pursuit clustering model in multiple attribute decision making *** optimum projection and the value of projection function can be obtained by the adaptive clustering differential evolution algorithm raised in this *** simulation results verify the validity and efficiency of this approach.

＜正＞Benefit and loss matrix of uncertain decision-making analysis reflects both the objective information structure of uncertain decision-making problem and the risk information of benefit chance and loss chance faced by decision-maker. The transform vector consisted of the natural state weights is quantitative expression of uncertain decision-making rule adopted by *** essential for resolving uncertain decision-making problem is how to transform benefit and loss matrix into compressed real vector with one dimension,where the biggest weight of the vector corresponds to the best action *** the information of benefit and loss matrix has been not mined sufficiently using the common methods for uncertain decision-making *** in this paper,the whole difference weights of the natural states can be determined using projection pursuit method,the local difference weights of the natural states can be determined directly using information entropy and accelerating genetic algorithm based fuzzy analytic hierarchy process,and the two kinds of weights can be combined into comprehensive weights according to the minimum relative information entropy principle, which can form a new uncertain decision-making analysis method based on information entropy principles,named UDM-IEP for *** application results show that the information of benefit and loss matrix can be mined more sufficiently using UDM-IEP than the common methods,that the decision-making information can be more provided by UDM-IEP than by the common methods,that decision-maker can actively or safely choose the best scheme based on the comparison between of benefit chance risk and loss chance risk contained in the benefit and loss matrix,that UDM-IEP is both simple and general,that its computation result is objective and stability,and that UDM-IEP can be widely applied in theory and practice of systems engineering.
