## Abstract

Disclosed is a method to create a digital twin which is a copy of a machine or a production system in a computer environment and usage of the created digital twin in the computer-based calculation. Digital twins which are developed by the method are created by physical laws/equations rather than solely by sensor data. Developed digital twins could be created/served with API's by dividing thereof into small pieces and could be resold through a market place in form of an application.

## Claims

### Claim 1

A computer-based calculation method wherein a user enters an online platform by an owned second device (1001), subsequently to browse applications which make engineering calculations, the user enters to a market place in an online platform where applications are sold (1002), the method characterized by comprising the following steps:
querying a requested application on the market place by the user (1007);
matching the application to a production system which yields a digital twin of the production system by the API consisting built-in functions, solvers, mathematical codes, recursive codes and loops (1013);
performing requested calculations with a digital twin application by the user (1014);
taking actions on production lines/machines such as changing operation parameters by the user or by the application; and
exiting out of the market place by the user (1019),
wherein after the user performs the requested calculations by means of the application (1014), the application asks the user whether obtained operation parameters are applied to the production system manually or not (1015), together with this:
if manual application is preferred, the user introduces the parameters received from the application to the production system (1016), and
if automatic application is preferred, the application is connected to the production system (1017) and the application applies parameters itself.

### Claim 2 (depends on 1)

A computer-based calculation method according to claim 1, wherein after the user enters the market place to browse applications which perform engineering calculations in the online platform where applications are sold (1002),
a. a server queries whether the user requires a private domain for using/developing the application or not (1003), and
b. as a result of the query, if private domain is required, the server performs user subscription processes in order for creating a private domain (1004).

### Claim 3 (depends on 2)

A computer-based calculation method according to claim 2, wherein:
a. if the user requires the private domain; the server queries whether the user requires an ecosystem characteristic which provides interaction with the other users or not (1005), and
b. if the user requires the ecosystem characteristic, the server integrates partner companies in the ecosystem to the private domain of the user (1006).

### Claim 4 (depends on 3)

### Claim 5 (depends on 1)

A computer-based calculation method according to claim 1, wherein after the user queries the requested application on the market place (1007):
a. if the application requested by the user is not present in the market place, a server asks the user whether the requested application is required to be developed or not (1008),
b. if the application which is not present in the market place is required by user to be developed, a developer develops the application by means of a graphical interface and API on the server (1009), and
c. if the application which is not present in the market place is not required by the user to be developed, the user exits from the market place (1019).

### Claim 6 (depends on 5)

A computer-based calculation method according to claim 5, wherein the user and the developer are the same person and thus a first device which is used by the developer and the second device which belongs to the user (9) is the same device.

### Claim 7 (depends on 5)

A computer-based calculation method according to claim 5, wherein the process of developing the application on the server by means of the graphical interface by the developer (1009) comprises the following steps:
