Information processing apparatus and program for displaying tree diagram

A program which is stored in a computer-readable medium and causes a computer to execute a process for displaying a tree diagram that represents, in a tree form, a hierarchical structure of a plurality of components which constitute an electronic product, comprising:

• causing the computer to read (i) attribute information, which indicates a characteristic quantity of each of the plurality of components, and (ii) parent-child relationship information, which indicates a parent-child relationship between the plurality of components, the plurality of components includes at least one parent component and a child component, the attribute information and the parent-child relationship information being stored in a memory unit and the parent-child relationship is defined under a restrictive condition such that each child component of the plurality of components does not have two or more parent components;
• causing the computer to execute a process for calculating, based on the parent-child relationship information, positions on the tree diagram where a plurality of nodes corresponding to the plurality of components arc to be arranged;
• causing the computer to execute a process for calculating, for each of the components, a sum of the characteristic quantity of the component and the characteristic quantities of all child components belonging to the component, based on the attribute information and the parent-child relationship information wherein a sum calculated for a parent component having no child components is given by the characteristic quantity of the parent component itself, and a sum calculated for a parent component having child components is given the sum of the characteristic quantity of the parent component itself and the characteristic quantities of all of the child components;
• causing the computer to execute a process for determining, for each of the nodes on the tree diagram, a mode of a branch line which is to connect the node to a parent node thereof, based on the sum calculated for each of the components;
• and
• causing the computer to execute a process for creating the tree diagram based on the calculated positions of the nodes and the determined mode of the branch line corresponding to each node.

An information processing apparatus which displays a tree diagram that represents, in a tree form, a hierarchical structure of a plurality of hardware components which constitute an electronic product, comprising:

• a memory unit to store (i) attribute information that indicates a characteristic quantity of each of the plurality of components and (ii) parent-child relationship information that indicates a parent-child relationship between the plurality of components, the plurality of components include a parent component and at least one child component associated with the parent component, and the parent-child relationship is defined under a restrictive condition that each of the at least one child component does not have a plurality of parent components;
• means for calculating positions on the tree diagram where a plurality of nodes corresponding to the plurality of components are to be arranged;
• means for calculating, for each of the plurality of components, a sum of (i) the characteristic quantity of the component and characteristic quantities of all child components of the component and (ii) the parent-child relationship information;
• means for determining, for each of the nodes on the tree diagram, a mode of a branch line to connect the node to a parent node thereof based on the sum calculated for the each of the components;
• and
• means for creating the tree diagram based on the calculated positions of the nodes and the determined mode of the branch line corresponding to each node.
