A printing center hаs 10 different cоlоr printers, аll оf which cаn produce poster of all sizes. However, due to power shortage, the maximal power available at the printing center is P, while to function appropriately, the printer k needs power . Besides, if printer k is used, we need to set it up first before it starts printing and the time for set-up is . Each printer used only needs one set-up at the beginning of the day before it starts working (there is no set-up between consecutive works on the same printer). And to avoid overheating, the maximal time for the printer k to work is , which doesn’t include set-up time. On July 24th, the center received 26 requests for event-poster printing, which must be completed on that day. The number of posters to be printed from request i is . The time to print one poster from request i by using printer k is . To make the task easier, each request can only be completed by one printer (splitting request is not allowed) Since the center is participating an ECO-Protection program, the staff decides to reduce energy usage by minimizing the total working time of all printers on that day. Please model this problem as LP (no restriction on variables but the constraints and objective function must be linear; define parameters, variables; write down formulations; for each constraint please give a brief explanation as we did in class)
