DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an alternative process selecting apparatus for construction and construction according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the alternative process selection apparatus for construction and construction of the present invention includes a basic process registration module 10, a basic process classification module 20, an alternative process registration module 30, an alternative process selection module 40 ), And an optimum process display module 50.

The basic process registration module 10 registers information on the operation period and the normal required cost of the basic process of the unit process first selected in the construction and construction project as basic information and stores it in the basic process DB 11 do. The information on the operation period includes information on operation period, remaining operation period, operation start date, operation end date, total float, and successors. Information on this period can be provided automatically in conjunction with the process control program or can be provided as an Excel file. Total float refers to the amount of time it takes to complete a task with the earliest start time (EST) and the latest finish time (LFT) without delaying the project delivery date. Successors are the activities of the Activity in the project.

The basic process classification module 20 classifies information on basic processes in items of construction and construction projects registered through the basic process registration module 10. For example, as shown in FIG. 2, the basic process classification module 20 classifies each unit process as an 'Activity ID item', and information on an estimated operation period registered for each unit process is referred to as' (Original Duration) item, the information about the remaining time period is classified as the 'Remaining Duration item', the information about the start date of the work is classified as 'Early Start' The information about the activity is classified as 'Early Finsh item' and the information about the normal expenditure is classified into the 'Budgeted Total Cost' item. Is classified by matching to the 'Total float' item.

The alternative process registration module 30 registers information on the alternative process that can be used as an alternative to the unit process of the registered building and construction project and stores the information in the alternative process DB 31. [ For example, as shown in FIG. 3A, the alternative process registration module 30 provides an 'alternative process input window' to receive alternative process information for a unit process, Window provides an "activity ID input menu" for inputting an activity ID of a unit process matching an alternative process and an "alternative number input menu" for inputting an alternative number of the entered activity ID. At this time, it is desirable to provide a list so that the unit processes of the registered construction and construction can be selected in the 'Activity ID input menu'. As shown in FIG. 3B, when an alternative number is input through the 'alternative number input menu', a 'alternative information input window' is provided to receive a work period corresponding to an alternative number and a required cost. As shown in FIG. 3C, the registered alternative process is stored together with the basic process.

The alternative process selection module 40 calculates the optimum unit process suitable for a construction and a construction project according to the following equations 1, 2 and 3 based on the construction period and the required cost of the basic process and alternative process registered for each process unit, The construction period, and the required cost. At this time, it is preferable that the selection criteria of the alternative process is the construction period, the required cost, and the like. That is, one of the alternatives is determined by using Equation (2) so that the sum of the direct ratio and the overhead ratio is minimized when the alternative process is selected by Equation (1), and the alternative process selected by using Equation Check if it violates the trailing relationship. If the entire process is changed by the alternative process, the process period and the cost can be confirmed.

[Equation 1]

I = Activity indicator, k = Alternatives for each activity, mi = Number of alternatives for the corresponding Activity i, and Costik (i) = Direct cost of selected Activity i, IDC = Indirect Cost, Total_Dur = Project Total Construction Period. By using the equation (1), the sum of the direct costs and the overhead costs is minimized when the alternative process is selected.

&Quot; (2) "

Here, i is the preceding activity and j is the trailing activity when the trailing relationship of Activity i and j has Fnish to Start. Where Esj is the earliest start time of the trailing Activity (ES below ES), Esi is the ES of the preceding Activity i, Dik is the construction period of each preceding Activity, Lag ij is the delay between the preceding Activity i and the Trailing Activity j It is time. Therefore, if the trailing relationship between the activities is Finish to Start, the trailing activity ES is always larger than the sum of the ES, construction period and delay time of the selected leading activity among the alternatives. Using Equation (3), it is possible to confirm whether the selected alternative process is in violation of the line-following relationship.

The optimum process display module 50 can confirm the information about the construction period and the construction cost, the total construction cost of the entire project, the total construction period, and the like by the unit process identified by the alternative process selection module 40 . For example, as shown in FIG. 4, the optimum process display module 50 can display the entire construction period and the construction cost of the project selected by the alternative process selection module 40, The operation period and the required cost of the alternative process selected by the unit process can be confirmed.

Hereinafter, an operation process of the alternative process confirmation apparatus for building and construction will be described.

First, when information on the first selected work period, normal cost, and continuity is registered as basic information for each unit process in the construction and construction project, it is classified into items. These basic information should be provided in an Excel file. At this time, the unit process of the project is classified into 'Activity ID item', the estimated operation period of each unit process is classified as 'Original Duration item', and the remaining period is classified into 'Remaining Duration item' , The job start date is classified as 'Start', the job end date is classified as 'job end date', and the normal cost is classified as 'Budgeted Total Cost' do. And, the free time that each activity can have without delaying the project delivery date is classified into 'Total float' item.

After these basic processes are registered, information on the working period and cost of the alternative process that can be used as an alternative to the unit process of the registered construction and construction project is input. For example, the ID of the unit process matching the alternative process is registered through the "Activity ID input menu" of the "Alternative process input window (Activity alternative input window)", and the number of alternative processes of the alternative process is inputted through the " And receives the operation period and the required cost for each alternative process through the 'alternative information input window'.

Based on the construction period and the required cost of the basic and alternative processes registered for each unit process, the following equations (1), (2) and (3) can be applied to the optimum unit process, construction period and cost And calculates the information about it. An alternative process to shorten the air can be selected by this formula to easily check the changed construction period, cost, and the like.

That is, one of the alternatives is determined by using Equation (2) so that the sum of the direct ratio and the overhead ratio is minimized when the alternative process is selected by Equation (1), and the alternative process selected by using Equation Check if it violates the trailing relationship. When the shortening period of the process is confirmed, the cost can be calculated for the shortened air, so that information on the final cost can be confirmed.

[Equation 1]

Figure 112015121357841-pat00007

I = Activity indicator, k = Alternatives for each activity, mi = Number of alternatives for the corresponding Activity i, and Costik (i) = Direct cost of selected Activity i, IDC = Indirect Cost, Total_Dur = Project Total Construction Period.

Figure 112015121357841-pat00009

Here, i is the preceding activity and j is the trailing activity when the trailing relationship of Activity i and j has Fnish to Start. Where Esj is the Early Start Time (ES) of the trailing Activity, Esi is the ES of the preceding Activity i, Dik is the construction period of each preceding Activity, Lag ij is the delay between the preceding Activity i and the trailing Activity j It is time. Therefore, if the trailing relationship between the activities is Finish to Start, the trailing activity ES is always larger than the sum of the ES, construction period and delay time of the selected leading activity among the alternatives.

In this way, the total construction cost of the newly selected project, the total construction period, and the construction period of the selected unit process and the construction cost are displayed so that the user can confirm it.
