Objective to establish a system to evaluate the mental workload on visual display interface in airplane cockpit after synthesizing three kinds of mental workload assessment techniques, i.e. main task measure method, physiology measure method and subjective evaluate method. Methods The evaluation indices of every kind of assessment techniques was defined, and the amount of each index through experiment and subjective inquiry was gained, weighted average was calculated and a quantification evaluation value of each kind of evaluation methods was got. At last, with weighted calculation of above three evaluation values, the evaluation value of mental workload on visual display interface in airplane cockpit was obtained Results in M kinds of different designs of visual display interface in airplane cockpit, the synthetic evaluation value of one design was the smallest and the mental workload of this design was the smallest. The design of the smallest mental workload was chosen prior as the final scheme of visual display interface in airplane cockpit .Conclusion The evaluation system is combined with present main evaluation methods of mental workload and utilizes their advantages. The evaluating results can be quantified more directly and clearly. With this evaluation system, the mental workload can be evaluated during the design of visual display interface of airplane cockpit and the best scheme can be confirmed.

The final aim of this research is to develop a quantitative evaluation system of shoulder joint function using a three-dimensional force display robot. In this paper, we proposed quantitative evaluation methods by which the results equivalent to the results of tests by a therapist can be obtained. The quantitative evaluation methods can be installed in the robot. We focus on two shoulder joint functions. One is stability and the other is cooperativeness. Two experiments were carried out to develop quantitative evaluation methods of shoulder joint function. In the experiments, subject’s forces were measured during the tests by the therapist. On the basis of the experimental results, we proposed a stability evaluation method using a regression equation of glenohumeral joint instability from the ratios between the right and the left subject’s force in the initial position during abduction, external rotation and horizontal abduction motion. Moreover, we proposed a cooperativeness evaluation method by detecting two thresholds related to sustainability of subject’s force.

Fuzzy Evaluation

At present, some classroom teaching evaluation methods are actually difficult to reasonably and fairly evaluate teachers’ true teaching level and classroom teaching quality. There are many shortcomings and drawbacks. In order to overcome the shortcomings of traditional teaching evaluation and enhance the evaluation effect, this paper combines the current advanced management methods with the merits of traditional evaluation methods, and applies the fuzzy evaluation method to combine qualitative assessment and quantitative assessment. First of all, establish a scientific and reasonable classroom teaching quality assessment index system, determine the standard assessment criteria, and then select and use the fuzzy comprehensive evaluation model to evaluate the classroom teaching quality, thus establishing a complete and effective teaching quality evaluation system.

Uncertainty theory is a branch of axiomatic mathematics dealing with experts’ belief degree. Considering the uncertainty with experts’ belief degree in the evaluation system and the different roles which different indices play in evaluating the overall goal with a hierarchical structure, a new comprehensive evaluation method is constructed based on uncertainty theory. First, index scores and weights of indices are described by uncertain variables and evaluation grades are described by uncertain sets. Second, weights of indices with respect to the overall goal are introduced. Third, a new uncertainty comprehensive evaluation method is constructed and proved to be a generalization of the weighted average method. Finally, an application is developed in evaluating software quality, which shows the effectiveness of the new method.

Manufacturability Evaluation

Ship manufacturability is one of the most important works for modern shipbuilding industry. The basic concept of ship manufacturability and its evaluation system are discussed first. Then the characteristics of ship manufacturability are analyzed. One kind of ship manufacturability evaluation (SME) strategy is put forward. Two evaluation methods of ship manufacturability (knowledge-based manufacturability evaluation and simulation-based manufacturability evaluation) are proposed too. With the proposed methods, the ship manufacturability can be evaluated reasonably.

Abstract With the rapid development of the times, the Internet has been deeply integrated into various fields, and many Internet companies have emerged at the historic moment, and economic activities such as mergers, reorganizations, acquisitions, issuance and listing, equity swaps, mortgages, bankruptcy and liquidation of Internet companies have also increased frequently. This has led to more and more value evaluation activities related to Internet companies, and the business model of Internet companies is different from traditional companies, so traditional corporate value evaluation methods cannot fully meet the special requirements of Internet company value evaluation. Therefore, we need to establish a sound Internet enterprise value evaluation system, and use more scientific and reasonable evaluation methods to ensure the interests of all parties to the transaction. Starting from the operating characteristics of Internet companies, this article analyzes the characteristics and difficulties of Internet corporate value evaluation, clarifies the effectiveness and limitations of the income method in Internet enterprise value evaluation, introduces the ARIMA model to improve the traditional income method and takes NetEase as an example. This method is applied to practice to verify its feasibility. So as to provide a scientific and reliable reference basis for Internet enterprise value evaluation.

Aiming at the problem that color image is difficult to quantify, this paper proposes an evaluation method of color image for small space based on factor analysis (FA) and gene expression programming (GEP) and constructs a correlation model between color image factors and comprehensive color image. The basic color samples of small space and color images are evaluated by semantic differential method (SD method), color image factors are selected via dimension reduction in FA, factor score function is established, and by combining the entropy weight method to determine each factor weights then the comprehensive color image score is calculated finally. The best fitting function between color image factors and comprehensive color image is obtained by GEP algorithm, which can predict the users’ color image values. A color image evaluation system for small space is developed based on this model. The color evaluation of a control room on AC frequency conversion rig is taken as an example, verifying the effectiveness of the proposed method. It also can assist the designers in other color designs and provide a fast evaluation tool for testing users’ color image.

The construction project bidding is a feasible method in engineering transactions and the main competition form of the construction activities under the conditions of the market economy. The bid assessment is an important link of bidding, and whether bid evaluation method is scientific or not, is directly related to the success of the tender. In the engineering construction field, at present the current commonly used evaluation methods are the comprehensive evaluation method and the lowest bidding price evaluation method. Based on fuzzy set theory and multi-objective people decision theory, we introduce fuzzy multi-objective people decision-making evaluation methods. And conducting research to put forward the evaluation index and weight method to determine the bidding decision model. Finally we apply it to actual case to make out the more standardized and scientific bidding evaluation method.
