Question

The printed cirouit board (PCB) of a particular brand of celuler phone is shown in the figure below. The PCBs arrive with components aftached except for the RCA Video, Audio, USB, and LAN. A PCB machine attaches these four components to the board. A robotic arm reaches a particular bin holding a component, takes the component and places on the board. Then, tool is selected to fix the particular component on the board. This continues until all these four components are attached on the board, and then the whole process starts with a new board. The times (in seconds) arm to reach a particular bin and bring the component on the board location to fix t, (2) setup to change the tool to fix a particular component, durations to complete all needed operations and movements: and (3) attaching a particular component on the board are summed up, and given as cumulative To From RCA Audio USB LAN RCA Audio 3 USB 1 6 LAN 54 CARS Formulate an appropriate mathematical model (and indicate its type) to find the order in which these four components should be attached on the PCB so that the total operation time for the boards is minimized.
