Next, FIG. 13 is a diagram illustrating a risk decision support (risk DM) screen at the time of implementing a web screen of a decision support system in procurement procurement of an LNG plant according to an embodiment of the present invention.

As shown in FIG. 13, in the risk decision support (risk DM) at the time of implementing the Web screen of the decision support system at the procurement procurement of the LNG plant according to the embodiment of the present invention, the evaluation of the risk management is performed in the Procurement DM step Based on the materials selected by the vendor, whether the Sole Vendor or not, by selecting the risk assessment items for each vendor. The list decision support 541 includes evaluation and evaluation result inquiry, and the evaluation 552 includes pre-stage evaluation, on-stage evaluation, and post-stage evaluation, The factor items are re-evaluated on the on-stage basis by level. After the on-stage evaluation is completed, the pre-stage evaluation items excluding the on-stage risk factor items in the post-stage can be constituted as the stage after the re- have. Thereafter, when the evaluation is finished, the evaluation result and evaluation content of the gate can be confirmed.

Specifically, in the pre-stage evaluation, after selecting the material to be managed and the risk factor management item, the evaluation can be performed on a user-by-user basis, and the list of the evaluator can be confirmed and the evaluation contents can be confirmed. In addition, the on-stage can evaluate the risk factors derived according to the pre-stage evaluation result according to the degree and the evaluation period defined by the risk manager, and check the evaluation list of the evaluator and the evaluation contents . In addition, the Post-Stage can evaluate the risk factor items of the Pre-Stage except for the risk factor items of the on-stage evaluation, by user, and confirm the list of the evaluator and the evaluation contents.

In addition, the evaluation result inquiry can confirm the evaluation result progressed by gates, and the evaluation contents of the risk management index, pre-stage, on-stage, and post-stage can be confirmed.

Next, FIG. 14 is a view illustrating a system management screen when implementing a web screen of a decision support system in procurement procurement of an LNG plant according to an embodiment of the present invention.

As shown in FIG. 14, the system management at the time of implementation of the web screen of the decision support system at the procurement procurement of the LNG plant according to the embodiment of the present invention registers and corrects the user, And data such as codes commonly used in a decision support system can be concentratedly managed in a common code for easy maintenance. This system management 561 includes OBS management, project master, rights management, and common code management.

Specifically, the user management can be configured by the system administrator and newly registered and modified by the user.

In addition, the rights manager 562 may configure the rights groups and configure rights for menus and modules for the groups. At this time, by registering the user in the group, the user can inherit the authority information of the group to which the user belongs.

Meanwhile, the decision support system for purchasing procurement of the LNG plant according to the embodiment of the present invention improves the algorithm of each module constituting the decision support system and upgrades the function, In order to enhance the functions of the support modules and to enable the system to operate in an integrated environment, a decision support system was established for procurement of LNG plants. For example, the procurement support system for purchasing procurement of an LNG plant according to an embodiment of the present invention includes process management for supporting design stage decision support by integrating process management, process management for procurement stage decision support, , Evaluation item management can be done in one integrated system.

Also, the decision support system for purchasing procurement of the LNG plant according to the embodiment of the present invention can manage the risk management in the integrated environment of the design stage and the procurement procurement stage.

In addition, the decision support system for purchasing procurement of the LNG plant according to the embodiment of the present invention enhances the function of visualizing the analyzed result by the analysis algorithm module, improves the user evaluation interface, can do.

In addition, risk assessment requires a lot of input for evaluation because it goes through three stages of pre-stage, on-stage, and post-stage. Therefore, the risk assessment of the decision support system at the procurement procurement of the LNG plant according to the embodiment of the present invention can represent the items inputted at the previous stage as default values so as to minimize the input of the evaluator.

As a result, according to the decision support system for purchasing procurement of the LNG plant according to the embodiment of the present invention, it is possible to supplement the lack of business management capability by supporting a decision making system necessary for the LNG plant business execution process in a structured decision system In order to satisfy the needs of each business entity, the project management manual and the decision support module of the LNG plant procurement stage can be suggested and applied. In addition, in performing a business, users can provide standard data for convenient configuration of business information, facilitate user's convenience in configuring business information, and more particularly, And user management for each project, and rights management for each menu / module, the convenience and usability of the decision support system can be maximized.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.

The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
