The following describes in detail, with reference to the drawings, an automatic lead time calculation device according to an embodiment of the present invention. However, the scope of the invention is not limited to the illustrated examples. In the following description, components having the same function and configuration are denoted by the same reference numerals, and their descriptions are omitted. [Overall Configuration of the Automatic Lead Time Calculation System] Figure 1 shows the overall configuration of the appropriate lead time automatic calculation system (hereinafter referred to as the system) 100 according to the present invention. For example, the system 100 comprises a server 10, which is an appropriate lead time automatic calculation device, and a user terminal 20. The server 10 and the user terminal 20 are connected to each other by a network N. Network N may include various communication network lines such as telephone lines, fiber optics, mobile communication networks, satellite communication lines, CATV (Community Antenna Television) lines, or other dedicated lines, as well as Internet service providers (i.e., the Internet) connecting them. Network N may also be a collective communication network where various communication networks such as LAN (Local Area Network), WAN (Wide Area Network), Wi-Fi (Wireless Fidelity), Bluetooth®, or NFC (Near Field Communication) are interconnected in a manner that allows them to communicate with each other. Furthermore, the connection method may be wired, wireless, or a mixture of wired and wireless connections. (server) Server 10 is provided at each location to which each user of System 100 belongs. Server 10 is equipped with the necessary functions for System 100. In this embodiment, Server 10 comprises a control unit 11, a storage unit 12, and a communication unit 13. The various parts of Server 10 are connected by a bus 14. Furthermore, the server 10 may be provided as a physical device or as an inanimate object in a cloud environment. If the server 10 is provided as a physical device, it may be equipped with a known display unit and operation unit so that various processes can be performed in the vicinity of the server 10. {Control Unit} The control unit 11 consists of a CPU (Central Processing Unit), RAM (Random Access Memory), and the like. The CPU reads various programs stored in the memory unit 12, loads them into the RAM, executes various processes according to the loaded programs, and centrally controls the operation of each part of the server 10. In particular, the control unit 11 functions as a calculation unit 111, a setting unit 112, an acquisition unit 113, and a display control unit 114 when the CPU executes a program. <Calculation Section> The calculation unit 111 calculates the appropriate lead time 251b (see Figure 7) based on the standard lead time for each process obtained by the acquisition unit 113 from the standard lead time database 121, the adjustment values obtained from the standard condition database 122, and the adoption rates of each design condition and construction condition obtained from the actual condition database 124, in response to instructions received from the user terminal 20. The details of this automatic calculation process for the appropriate lead time by the calculation unit 111 will be described later. <Setting Section> The setting unit 112 sets (changes) the standard lead time in the standard lead time database 121 and the addition/subtraction values in the standard condition database 122 in response to instructions received from the user terminal 20. <Acquisition Department> The acquisition unit 113 acquires the necessary data from various databases stored in the storage unit 12, as described above
