As well as a variety of offshore structures. The hull block may be part of the hull assembled with other hull blocks to form the hull. Examples of equipment include parts and equipment other than hulls, such as engine related equipment, pipes, cabin interior structures, steering gear, electric generators, electric wires, wiring, electric devices such as electric devices, and various other components and equipments , But is not limited thereto.

The equipment installation information determination unit 110 calculates the estimated installation time for each installation order of a plurality of pieces of equipment and determines an optimum installation order of the plurality of equipment products so that the estimated installation time is minimized. The equipment installation information determination unit 110 can calculate the estimated installation time while varying the installation order of the plurality of equipment products. For example, when it is desired to determine the installation order of N (N is an integer of 2 or more) pieces of equipment, the equipment installation information determination unit 110 can calculate the estimated installation time for each N (N factorial) have.

In one embodiment, the predicted installation time may be determined by adding all of the installation times expected in the installation order of the fittings. The installation time of each piece of equipment varies according to the installation order of the plurality of pieces of equipment. That is, the installation time of each piece of equipment varies according to the installation order of the plurality of pieces of equipment in accordance with the previously installed equipment. Therefore, the optimal installation order of the equipment products can be determined from the change of the installation time according to the installation order of the equipment products, thereby shortening the installation work time of the equipment. The optimum installation sequence information of the plurality of equipment products determined by the equipment installation information determination unit 110 is provided to the enhancer 140 so that the operator can provide information necessary for installation of the equipment product.

In the example of the installation delay time table shown in Fig. 3, the installation delay time required for installation of the equipment A2, A3, A4 is set to t12, t13, t14 while the equipment A1 is installed. , A3, and A4 are set to t21, t23, and t24, respectively, and the installation delay times required to install the equipment A1, A2, and A4 are set to t31, t32, and t34, respectively, And the installation delay time required for installing the equipment A1, A2, and A3 in the state that the equipment A4 is installed is set to t41, t42, and t43, respectively. t1, t2, t3, and t4 are installation times when the first and the second products A1, A2, A3, and A4 are installed, respectively.

The installation delay time between a plurality of pieces of equipment may be determined based on a size of a plurality of pieces of equipment, a fixing method of a support for installation of the equipment or the like, a position where a plurality of pieces of equipment are to be installed, And can be determined automatically or by operator's setting. For example, the installation time can be determined to be a large value in proportion to the size of the equipment, the number of supports necessary for installation of the equipment, and the proximity of the equipment installation route and the nearby equipment to be installed in advance. If the installation of the equipment is impossible due to the interference with the nearby equipment, the time for removing the peripheral equipment and the time for installing the peripheral equipment after the installation of the equipment may be added to the estimated installation time.

As another example, in the case of installing in the order of the equipment A2, A4, A1, and A3, the installation time calculating unit 112 calculates the installation time t2 of the equipment A2, the installation time t24 of the equipment A4, (t2 + t24 + t21 + t41-t1 + t23 + t43 + t13-2t3), which is the sum of the installation time t21 + t41-t1 of the equipment A3 and the installation time t23 + t43 + t13-2t3 of the equipment A3, A2, A4, A1, A3 You can determine the estimated installation time for the installation sequence.

As another example, in the case of installing in the order of the equipment A4, A1, A3 and A2, the installation time calculating unit 112 calculates the installation time t4 of the equipment A4, the installation time t41 of the equipment A1, The time (t4 + t41 + t43 + t13-t3 + t42 + t12 + t32-2t2) obtained by adding the time t43 + t13-t3 and the installation time t42 + t12 + t32-2t2 of the equipment A2 is calculated It is possible to determine the predicted installation time for the installation order of the equipment A4, A1, A3, A2.

In the case where the number of equipment items is N, the installation time calculating unit 112 calculates N (N-1) × (N-2) × (N-3) × The predicted installation time can be determined for each of the installation sequences of × 2 × 1 (N!). When the installation time determining unit 112 determines the predicted installation time for each of the installation orders of the plurality of pieces of equipment, the installation order determining unit 114 determines the installation order of the plurality of pieces of equipment, The optimum installation order of the equipment is determined.
