requirements be satisfied with the minimum cost? a. How can these b. How can the formulation be made more efficient? 37. A manufacturer of bathroom fixtures produces fiberglass bathtubs in an assembly operation that consists of three processes-molding, smoothing, and painting. The number of units that can undergo each process in an hour is as follows: Process Output (units/hr.) Molding Smoothing Painting 12 10 (Note: The three processes are continuous and sequential:; thus, no more units can be smoothed or painted than have been molded.) The labor costs per hour are $8 for molding. $5 for smoothing, and $6.50 for painting. The company's labor budget is S3,000 per week. A total of 120 hours of labor is available for all three processes per week. Each completed bathtub requires 90 pounds of fiberglass, and the company has a total of 10.000 pounds of fiberglass available each week. Each bathtub earns a profit of $175. The manager of the company wants to know how many hours per week to run each process to maximize profit. a. Formulate a linear programming model for this problem. b.
