On-site system building support tool

An on-site system building support tool for building an on-site system on a screen of a display unit to simulate the on-site system, the on-site system including a plurality of machines, each of which is self-propelled, travelable, or transportable, and the on-site system processing an object to be processed in situ where the object to be processed has been produced,

• wherein computing means performs the steps of:
• displaying a layout creation screen on the display unit, the layout creation screen including:
• an icon area for displaying a plurality of icons, each of which represents, in a discriminable manner, any of various kinds of machines that can be used in the on-site system, or any of processes to be performed in the on-site system;
• and
• a canvas area in which the on-site system is virtually built;
• displaying, in the canvas area, an icon selected in the icon area according to an operation signal from an operation device based on GUI operation;
• after the plurality of icons are positioned in the canvas area, displaying, in the canvas area, a mark indicating, in a discriminable manner, how each process which is associated with the plurality of icons selected in the canvas area is connected to a previous or next process of each process;
• when an icon is selected and clicked in the canvas area, displaying, on the display unit, a model setting screen used to specify a model of a machine to be used in a process associated with the selected icon, and to specify the number of the machines, and a workload of the machine;
• and
• on the basis of information about the number of machines corresponding to the model and the workload of the machine specified on the model setting screen and about fuel consumption provided beforehand, calculating a load which the on-site system virtually built on the canvas area applies to environment, and then displaying the result of the calculation on the display unit;
• wherein:
• a particular icon representing a machine or a process, which involves branching of flow of a processed object, has a plurality of ratio setting objects, each of which is used to specify a sorting ratio of the processed object;
• the sorting ratios of the processed objects displayed in the plurality of sorting ratio objects are always 100% in total;
• and
• when a sorting ratio displayed in any of the ratio setting objects is changed, sorting ratios displayed in the other ratio setting objects are also changed accordingly.
