Three different types of material handling equipment are being considered for selection to perform six moves. Capital costs for one unit of equipment type 1, 2 and 3 are 3000, 2500 and 1500, respectively. Variable costs (W) and transportation times (hy) for every equipment type (i = 1, 2, 3) and every move (= 1, 2,...,6) are given in the following table, where M denotes a very large number. The facility is intended to operate for 10 hours/shift for 280 working days and hy values are represented in hours per shift.

In the remaining time, type B equipment needs to be recharged/refueled and type C equipment is used for loading and unloading heavy loads. Equipment Type A can be used as a high capacity temporary storage between departments and equipment Type B can not handle very heavy items. a) Use the heuristic approach (Hassan et al., 1985) covered in class to find which equipment Move 2 will be assigned to. Clearly show your work. b) Considering the general properties of the equipments mentioned in the question, write down the types of these material handling equipments. : Type B: : Three different types of material handling equipment are being considered for selection to perform six moves.
