Patent ID: 7127382

Claim:
A production simulation apparatus comprising: data storage means for storing mounting data about plural types of assembly boards and apparatus data about a component-mounting apparatus which includes: plural component feeders for feeding components; holders for holding said components; and a transfer head for picking up the components from the component feeders and mounting the components on bare boards, said apparatus data includes compatibility data which indicates compatibility between said feeders and said holders; production data generating means for generating, according to the mounting data and the apparatus data, production data for the transfer head to mount the components; command inputting means for inputting production command data including a production quantity of the assembly boards, a production order of the assembly boards to be manufactured, and for selecting between a first premise and a second premise, said first premise has location of one of said component feeders different for two of said assembly boards having a component of said one of said feeders in respectively different locations, said second premise has location of said one of said component feeders fixed for said two of said assembly boards, location of said one of said component feeders different or fixed depending upon said compatibility data for said feeder and ones of said holders; production simulating means for simulating a production based on the production data and the production command data to calculate a total number of the assembly boards manufactured with time by the component-mounting apparatus; and displaying means for displaying two different results of the simulation, depending upon whether said first premise or said second premise is selected.
