An operation command generation device, comprising: an execution order determination unit configured to determine, based on respective arrangement positions of a plurality of process symbols on a protocol chart comprising the plurality of process symbols, each process symbol representing a process for a process subject, an execution order of the plurality of process symbols; and a process symbol conversion unit configured to respectively convert the plurality of process symbols into jobs for a process system comprising at least a robot so that the processes represented by the plurality of process symbols are executed in the execution order determined by the execution order determination unit; wherein the protocol chart comprises an initial symbol representing a container for the process subject and another initial symbol representing another container for another process subject, wherein each of the initial symbols is respectively associated with one or more process symbols arranged along a first direction from the respective initial symbol on the protocol chart and each representing an individual process to be carried out on the respective container, and wherein said initial symbols are arranged on the protocol chart separate from each other in a second direction intersecting the first direction; and wherein the execution order determination unit is further configured to determine the execution order of at least two process symbols, which are equal to each other and arranged at the same position in the first direction, based on the arrangement positions of the at least two process symbols in the second direction. an execution order determination unit configured to determine, based on respective arrangement positions of a plurality of process symbols on a protocol chart comprising the plurality of process symbols, each process symbol representing a process for a process subject, an execution order of the plurality of process symbols; and a process symbol conversion unit configured to respectively convert the plurality of process symbols into jobs for a process system comprising at least a robot so that the processes represented by the plurality of process symbols are executed in the execution order determined by the execution order determination unit; wherein the protocol chart comprises an initial symbol representing a container for the process subject and another initial symbol representing another container for another process subject, wherein each of the initial symbols is respectively associated with one or more process symbols arranged along a first direction from the respective initial symbol on the protocol chart and each representing an individual process to be carried out on the respective container, and wherein said initial symbols are arranged on the protocol chart separate from each other in a second direction intersecting the first direction; and wherein the execution order determination unit is further configured to determine the execution order of at least two process symbols, which are equal to each other and arranged at the same position in the first direction, based on the arrangement positions of the at least two process symbols in the second direction.
