- A company makes hundreds of products, but six of them (A, B, C, D, E, F) are considered "class A" items because they account for 90% of the company's revenues. Each product undergoes stages of production at five workstations. The five workstations must be positioned along a straight line in an assembly-line fashion to maximize space utilization. The demand for each product in a typical week is given in the table below, along with the sequence of workstations that each product must visit. a. Develop a flow matrix that shows the number of trips between each pair of workstations. b. Calculate the weights w = fycu(ru + 0.5 - (4 + 1)) from: (i) your flow values, (ii) the lengths below, (iii) clearances of 3 meters between adjacent workstations, and (iv) each cy is 1. c. Determine a single-row layout using the Modified Spanning Tree heuristic from class.
