Design support device and design support method

A design support device which supports a design project achieved by executing a plurality of tasks where one or a plurality of subtasks are included, the design support device comprising:

• a unit which stores the operation history of a design tool operated by an operator and a history of creating/referring a file as design history data;
• a unit which compares date information in the design history data with date information of a task in a design procedure table of each product or project, and associates and registers the task and the design history data as task-design history relevant data to a design history database;
• a unit which divides the design history data in a unit of subtask on the basis of the task-design history relevant data, and associates and registers the subtasks and an execution order of the subtasks in a design process database as design process data;
• a unit which calculates a relevance of the subtask from a relation between a creation file and a reference file in the subtask and a relation between the subtask and the execution order and registers the relevance to the design process database as subtask relevance data;
• a unit which sets the created design process data as in-process data for an in-process design work, sets the design process data registered to the design process database as past design process data, compares the in-process data with the past design process data, estimates a subtask to be performed in a subsequent design work with respect to the in-process design work, registers the estimate subtask as the estimate subtask data;
• a unit which calculates an optimal execution order on the basis of an average man-hour of the estimate subtask and the subtask relevance data, and registers the optimal execution order as an estimate design process;
• and
• a unit which displays the estimate design process through an output device.

A design support method which supports a design project achieved by executing a plurality of tasks where one or a plurality of subtasks are included, comprising:

• storing sequentially design history data of a design performed by a designer using a calculator;
• associating the design history data with the task to sequentially generate task-design history relevant data;
• defining a subtask with respect to the task-design history relevant data to sequentially generate design process data;
• generating subtask relevance data which indicates a relevance between the subtasks with respect to the plurality of pieces of design process data;
• estimating a subtask to be performed in a later design work with respect to an in-progress design work from a difference between past design process data of a project performed in a past and in-process data in a project performed currently to obtain an estimate subtask;
• and
• presenting estimate design process data of which an optimal execution order is calculated to the designer as the estimate subtask.

A design support method which supports an operator to perform a design project using a calculator, the project being achieved by executing a plurality of tasks where one or a plurality of subtasks are included, comprising:

• analyzing a design history of the operator from the calculator in a unit of subtask by comparing the history with a design procedure table;
• calculating a relevance between subtasks from a relation between a creation file associated with the subtask and a reference file;
• extracting an optimal design process from the relevance;
• and
• presenting the optimal design process to the operator.
