Method for allocating resources and processes for design and production plan scheduling

A scheduling computer system for generating a scheduling chart, the computer system comprising:

• resource defining means for inputting an attribute of each of a plurality of resources;
• process defining means for inputting an attribute of each of a plurality of processes which are processed in a predefined sequence;
• time setting means for inputting the processing start time and desired processing end time of each of said plurality of processes;
• process selecting means for sequentially selecting a process, to which a resource is to be allocated, from said plurality of processes;
• temporary allocating means for temporarily allocating each of said plurality of resources to the process selected by said process selecting means;
• first evaluating means for evaluating the end time of a sequence of said plurality of processes by finding the end time of the sequence of said plurality of processes after said temporary allocation and for defining a resulting time evaluation value as the first criterion;
• second evaluating means for evaluating the fitness of a resource for a process based on the attribute of the resource inputted by said resource defining means and on the attribute of the process inputted by said process defining means and for defining a resulting fitness evaluation value as the second criterion;
• resource determining means for calculating an evaluation value for the combination of a process and a resource by evaluating said first criterion and second criterion for each of said plurality of resources and for determining the optimum resource for the process by comparing said evaluation values of all the resources;
• process allocating means for sequentially allocating a resource determined by said resource determining means to a process selected by said process selecting means as a final result;
• and
• means for generating the scheduling chart illustrating the process to which the resources have been allocated by the process allocating means,
• wherein said process selecting means does not select processes to which resources have been already allocated by said process allocating means as objects of said temporary allocation.
