Schedule managing method and schedule managing apparatus

A component mounting system with a production area for producing a plurality of models of products on a production line and a preparation area for arranging members corresponding to the plurality of models on a carriage provided carrier tape which is attached to the production line, the system comprising:

• a managing computer connected to an arrangement work supporting device via a communication network, the arrangement work supporting device transmitting information via a communication network to the managing computer regarding a connected carriage, the managing computer including:
• a display that displays, on a single screen, a first region displaying a production schedule, a second region displaying a preparation work schedule, and a third region displaying a number of workers, each of the first region, the second region, and the third region being displayed along a common production time point;
• an input device used to input and change a number of workers displayed in the third region, the third region displaying the number of workers scheduled to perform an arrangement work of arranging members to a carriage provided carrier tape in association with the production time point;
• and
• a processor comprising:
• a preparation time point changer that, in response to a change to a number of workers input via the input device, changes a start time point or an end time point of the arrangement work in the preparation work schedule displayed in the second region based on:
• information acquired from the arrangement work supporting device, a work quantity of the arrangement work, and the number of workers input via the input device;
• and
• a production time point changer that, in response to a change in the preparation work schedule, changes a start time point or an end time point of the production of the products in the production schedule displayed in the first region based on the changed start time point or an end time point of the changed arrangement work by the preparation time point changer,
• wherein the managing computer manages a plurality of component mounting lines via the communication network,
• the arrangement work is performed on a carriage connected to the arrangement work supporting device according to the updated preparation work schedule, and
• the component mounting lines are managed to produce a plurality of mounting boards according to the updated production schedule.
