The system is designed by adopting a three-layer client/server mode, and a new level is added to the three-layer client/server mode (hereinafter referred to as the three-layer mode) on the basis of the two-layer mode. This mode logically divides the application functionality into three layers: a client display layer, a service logic layer and a data layer. The client display layer is a graphical interface for providing application services for the client, and is helpful for the user to understand and efficiently locate the application services. The business logic layer is positioned between the display layer and the data layer, and provides a clear layer specially for realizing the business logic, the application model related to the system is packaged at the layer, and the user representation layer is separated from the database code. This hierarchy provides a link between client applications and data services, the main functions being to enforce application policies and package application schemas, and to present packaged schemas to client applications. The data layer is the bottom of the three-layer schema and is used to define, maintain, access, and update data and manage and satisfy requests for data by application services.

The system also comprises a database module which is an important module of the simulation training system. Through the database module, the user can conveniently complete the management of the data. Such as functions of querying, adding, deleting, and modifying data. These data include various forms such as trainees, scenes and performance reports. The user can set up the required subjects through the data, and can store the necessary data into the corresponding tables of the database, thereby facilitating the technical analysis afterwards.

The database module of the system is realized by a connection pool technology. For databases, manufacturers often open up corresponding areas in memory to store data that may be accessed multiple times and statements that may be executed multiple times, so that the data may not be accessed the next time it is requested again and the statements may not be compiled again the next time they are executed. Similarly, the data persistence layer employs caching techniques to store portions of commonly used data that have been retrieved from the database. When the client accesses the persistent layer, the persistent layer firstly accesses the cache, if the client can hit the cache, the data is directly extracted from the cache, and otherwise, an instruction for extracting the data is sent to the database. This design can greatly increase data access speed.

The specific implementation method of the database module of the system comprises the following steps:

1. obtaining a reference to a connection pool or to an object that manages multiple connection pools;

2. obtaining a connection from the connection pool based on the determined object;

3. after the connection is used, the connection is returned to the connection pool.

And meanwhile, the connection number of the connection pool and the maximum use times of each connection are controlled by setting parameters of the connection pool.

The data layer is an important component in the framework of a modular programming system and takes on the task of storing data. In consideration of the practical situation of the popular operating system, the background database of the system adopts an Oracle8 database.

Meanwhile, the step of determining the SQL Server security policy comprises the following steps:

1. carrying out verification mode and login verification, and assigning SQL Server management capability to a user by using a Server role; (ii) a

2. Assigning database capabilities to users using a database role;

3. determining a Windows 2000 account for running the SQL Server service;

4. planning an application security policy;

5. security requirements are determined for the link server.

An evaluation method of a military training information system based on a network mode, as shown in fig. 7, includes the following steps:

step 1, initializing;

The system evaluation part is mainly realized by software, acquires detailed information of an operation flow by monitoring an operation training process in real time, and evaluates the operation of an operator by software processing.

The operation process of the training system is complex and rigorous, and a standard operation process is provided. Each step of the normal operation flow of the system is coded with a sequence number, so that the normal operation flow becomes a standard number sequence X. The data of the actual operation process of an operator are collected, the step sequence numbers of the regular operation flow are compared, the actual operation process can be converted into another digital sequence Y, and the sequence similarity comparison is carried out on the sequence X and the sequence Y. By sequence similarity comparison, it is meant that regions of two sequences that are significantly similar are compared.

Unlike time series in digital signal processing, in the present system, the independent variable of an event sequence constituted by an operation flow is a finite integer representing the order, and the dependent variable is a constant characterizing an event, such a constant having no size fraction. And the independent variable of the time series can be continuous real number, and the dependent variable thereof is a constant with magnitude meaning. The meaning of the event sequence and the time sequence is different, and the processing and evaluation methods are naturally different. The current common algorithm defines the distance between two sequences by finding the largest identical sub-sequence (LCS) of the two sequences, and this algorithm does not take into account the effect of the different sub-sequences on the whole sequence. The second algorithm is to define the distance between two sequences by comparing the minimum operation cost (i.e. edit distance) of the two sequences, and this algorithm ignores the weight difference of different edits, so that the simulation training model cannot be accurately evaluated. The system provides a more reasonable sequence evaluation algorithm compared with the two evaluation methods in consideration of the practical application requirements of operation flow evaluation.

In the system, a training evaluation algorithm is converted into a planning solution about a multidimensional 0-1 knapsack problem, and a branch and bound method is adopted to solve the 0-1 knapsack problem for optimal solution. Finally, a complete training evaluation system is formed.

The system provides an application context of an event sequence similarity evaluation algorithm, namely evaluation of a list of operation flows. The sequence of events for the present system is a 2-dimensional problem: attribute dimensions and ordinal dimensions. Defining possible operations in the operation flow as set R ═ { a ═ a₁,A₂,......,A_nThe element in (1), n is a finite value. The ordinal dimension represents the position of an operation in the operation stream. Such an operation may be performed using a 2-dimensional vector E ═ a_iI } represents (where i e N, ai e R), the sequence consisting of such vectors is a typical sequence of events.

Solving two columns of operation flows (event sequences) F₁＝{E₁,E₂,......,E_mAnd F₂＝{E₁',E₂',......,E_kOne of the typical applications of the similarity of' } is to evaluate the actual operation quality of a student under a given standard operation flow. For example, if the trainee and the standard sequence are identical, the trainee's score is full, and the operation error and missing operation steps all reduce the trainee's score. Such an operation flow evaluation may be widely applied to anyAn evaluation system of which event sequence.

Considering the simplest case, F1 is a standard sequence, in which each element is not repeated. F2 is the sequence to be evaluated (student action stream) whose number of elements is greater than zero. In practical situations, F1 may be repeated, and the standard sequence of the correct operation flow may be several, and may be expanded and revised based on the above.

By the above definitions, several properties of F1 and F2 can be seen:

1. any event attribute in F2 exists uniquely in the geometry formed by the event attributes of the F1 element.

2. The relationship between the number m and k of elements of F1 and F2 may be greater than, equal to, or less than.

3. The elements of F1 and F2 may constitute an intersecting element, representing the line connecting the two elements of the same event attribute of F1 and F2. The intersecting elements may be represented by a three-element structure. The number of intersecting elements is equal to the number of F2.

4. The intersecting elements may be mutually exclusive in order. For example, cross element 2 and cross element 3 intersect, and cross element 5 and cross element 6 point to elements of the same canonical sequence, then cross element 2 and cross element 3, and cross element 5 and cross element 6 do not hold at the same time. Cross members reflect the similarity of two sequences. Due to mutual exclusivity between cross-members, the similarity of two sequences can be reflected in order to find a set of cross-members such that their sum is maximal. The influence of the redundant elements is deducted, which is also part of the similarity evaluation, by considering that the redundant elements divide the sequence to be evaluated into several segments.

5. A reasonable optimal solution can be obtained by judging a set of established cross elements, only one mutual exclusion condition is not enough, and corresponding weights are defined for the cross elements. The sum of these weights is exactly equal to the full score value. When the standard sequence is completely equal to the sequence to be evaluated, the cross elements do not have mutual exclusion, and then the score corresponding to the sequence to be evaluated is exactly the full score.

6. Solving the cross element score and the problem with mutual exclusion condition is converted into a multidimensional 0-1 knapsack problem, which can be described as:

By solving for the optimal cross element combination, the sequence framework of the sequence to be evaluated can be determined. And defining a sequence frame as a subcolumn which is composed of no redundant operation steps and meets the standard sequence order in the sequence to be evaluated, wherein the rest elements are redundant operations.

Various conditions needing to be processed in the evaluation are analyzed according to the actual training operation, and the following conditions are mainly adopted: the method has the advantages of being capable of achieving multiple accurate operation sequences, achieving redundant operation actions without response excitation, corresponding to different scores for the operation actions, and protecting the influence of operation time. According to the analysis of the four aspects, the system is designed and realized, and methods of eliminating non-excitation response, multi-sequence matching, self-defining operation step scores and the like are adopted in sequence.

According to the military training information system based on the network mode and the evaluation method thereof, the military training information system has higher network security and is convenient to use and maintain, and the military training information system is used in a simulation training project of a college at present, so that the actual functional performance and the security are better verified.
