Question 2 Four equal sized stations are served by an AGV on a linear bidirectional track as shown in figure 1. Each station block is 30ft*30ft. The product routine information and required production rate and the cost of handling are given in tables 3 and 4. Assume that the pickup/delivery stations are located at the mid-point of the station. A B D Fig. 1: Block Diagram Table 3: Processing sequence and production rate.

What does AGV stands for? b. Do the above givens satisfy the SLP model studied throughout the course? Justify your answer. c. Determine a layout arrangement based on the pairwise exchange method. Assume a flow factor of 50%. d. Assume reasonable closeness ratings and find an initial layout using a qualitative method
