Abstract – At present, it is very important for universities to improve the comprehensive qualifications of students and social competitiveness. As society develops and the recruitment of students continues to expand, the challenges and difficulties faced by students graduating are also growing. It is a core requirement of the development of university education to evaluate students qualifications objectively and accurately and to give appropriate education accordingly.

Establishing an objective and comprehensive student qualification assessment system to bring education closer to more realistic needs and provide more comprehensive and accurate data when organizations choose students is an important task in university work.

Although several universities have already had considerable success in terms of qualification management, teaching management, and so on, further improvements in the assessment system of students qualification are a real challenge for change and development. On the other hand, when assessing students qualifications in many universities, such an approach often lacks scientific and objective qualities to assess students overall performance using a series of qualitative methods.

In paper, we have implemented an assessment system of students qualification that combines qualitative and quantitative factors using an integrated hierarchical process (IAHP) tool developed in the Net-oriented System Description Language (NSDL) environment, which combines the advantages of Petri nets and object-oriented programming languages to provide scientific, objective, intuitive and flexible evaluation systems.

Keywords – IAHP, Qualification Assessment, Petri Net, Object-oriented Programming Language, Net-oriented System Description Language,

  1. INTRODUCTIONAnalytical Hierarchy Process (AHP) is a comparative assessment method using human perception, which is a decision- making method that selects the best of the various alternatives selected by modeling the actions of the decision-making factors in a hierarchical structure.

    AHP is widely used in various fields of economy, military, society, management, education, medicine, etc due to its ability to deal with qualitative (fuzzy) or quantitative data, logical, systematic, simple and effective analysis.

    Developing a convenient and reliable decision-making tool has great practical significance.

    In the past, AHP tools have been developed and used mainly in a graphical user interface, with a strong spreadsheet and a table-based Execl program, such as XLSTAT, AHP Decision, AHP Solver, AHPcalc, AHP-jar, FuzzyAHP, and Ahp_Calculator[1-8].

    These tools have already been used for hierarchical analysis by using the appropriate input to users based on a hierarchical model built with image or graphical modeling tools. In other words, there was a lack of automatic informational links between the hierarchical model building and the hierarchical analysis module. Finally, when the number of layers, criteria, and alternatives are large and the interaction is complex, the overall analysis is time consuming and laborious and the complexity of users use is unavoidable.

    The characteristics of the proposed IAHP and other AHP tools are shown in Table 1.

    In addition, there are many software development tools that combine the advantages of Petri nets and object-oriented programming languages with good intuition and convenience in modeling in the world [9-16].

    • This means supported, no support

    Hence, we developed IAHP in NSDL environment that was developed by combining the advantages of Petri nets and object-oriented programming languages. In IAHP, the hierarchical structure model is described by Petri net diagrams to enhance the intuition and convenience of the AHP tool.

  2. INTEGRATED ANALYTICAL HIERARCHY PROCESS TOOL
    1. Net-oriented System Description Language- NSDLThe NSDL (Net-oriented System Description Language) is an independent software development tool that uses the Petri nets and object-oriented programming language VB based on Microsoft.NET Framework 4.0 libraries.

      The formal representation of NSDL is as follows.

      Where,

      • P is the finite set of places,
      • T is the finite set of transitions,
      • A is the finite set of arcs,NSDL [P, T , A, M , F , , O]

        (1)

      • M is the finite set of markings (includes the object tokens),
      • F is the finite set of functional code,
      • is the finite set of attributes (delay time after firing, firing rate, priority, weight, capacity, type of elements, competition extraction setting and color, etc.) and
      • O is the finite set of user-defined objects modeled with NSDLs functional codes.

      In NSDL, systems are modeled as follows.

      • In the upper level of system,
        • Diagram models are constructed according to the mutuality and the logical action sequence of system components.
        • Graphical User Interface models can be configured according to the demands of the user. (optional)
        • Setting properties of diagram and interface elements
      • In the lower level of system,
        • Standard and user defined functional code model of upper level diagram elements are edited.
        • Dynamic setting properties of diagram and interface elements by functional codes during the simulation.

      In NSDL, we introduced elements such as in/out place terminal, equal place and subsystem, functions such as model library management, code debugging and model compiling to further improve its flexibility, convenience, extensibility and productivity.

    2. Integrated Analytical Hierarchy Process (IAHP) Method

      Algorithm diagram of IAHP

      The algorithm diagram of IAHP is shown in Fig. 1.

      Figure 1. Algorithm diagram of IAHP.

      The process of making AHP structure model in tool is as follows.

      Hierarchical Structure Modeling Module

          • User can used one goal layer element (A1), 17 criteria layer elements (B1- K1), one alternative layer element (S1) and one reference arc element to model hierarchical structure, also one sub-criteria and sub- alternative element by subsystem element. These elements are created and stored in the Hierarchical Analytical Library file ahp.ndt.
          • Insert the model library file ahp.ndt into the toolbox.
          • Using the modeling elements in the toolbox, create an AHP structural model that the user needs and add the attributes for the example (Fig. 8-9).
          • For convenience, If there are so many criteria (or alternatives) in one layer can be used as sub-criteria (alternatives).Generation of incidence table, checking and revising for hierarchical structure model
          • Generates incidence table according to the relationship of each element in the hierarchical structure model (Table 1).
          • The user checks the consistency of the built-in hierarchical structure model with the generated incidence table and performs modifications and storage of the built-in model.AHP module
          • Based on the incidence table obtained from the created AHP structural model, we implement AHP algorithm using the VB script language of NSDL.
          • The user can directly input qualitative and quantitative criteria. Also, the NSDLs script language and the best GIS analysis

      tool ArcGIS were combined to input the analysis results for the relevant criteria.

    3. Evaluation of Qualitative CriteriaBased on incidence table, the following AHP algorithm is constructed by VB language of NSDL. Step 1: Judgment Matrix Construction

      When AHP diagram is constructed, judgment matrix to reflect experts subjective assessment is made. The judgment matrix may be made by comparison table.

      Table 2. Meaning of Comparison Values.

      Comparison value Meaning
      1 Equally importance
      3 Moderately importance
      5 Strongly importance
      7 Very strongly importance
      9 Extreme importance
      2, 4, 6, 8 Intermediate values

      Step 2: Calculation of the weight by geometric average.

    4. Evaluation of Quantitative CriteriaThe quantitative criteria may be normalized by simple, max/min and sigmoid method according to the users requirement. The sigmoid transformation method uses the following expression to estimate the importance:
    5.  

      Here, quantitative criteria are inputted by analysis results and normalized by simple method.
