The Omega Manufacturing Company has discontinued the production of a certain unprofitable product line. This act cre- ated considerable excess production capacity. Management is con- sidering devoting this excess capacity to one or more of three prod- ucts; call them products 1, 2, and 3. The available capacity on the machines that might limit output is summarized in the following table: Available Time Machine Type (Machine Hours per Week) Milling machine 500 Lathe 350 Grinder 150 The number of machine hours required for each unit of the re- spective products is Productivity coefficient (in machine hours per unit) Machine Type Product 1 Product 2 Product 3 Milling machine Lathe 3 5 5 4 Grinder 3 2

True, False or Uncertain. Explain your answer. Own wage elasticity JELLlincrease if product demand elasticity n? is high. In short run, when there is an increase in wage rate, each firm will hire less labor and so the industry labor demand is simply the horizontal summation of firm's labor demand. а. b. Labor demand is represented by the marginal revenue produce schedule (MRP) when we have competitive product market while it will be represented by the value of marginal product schedule (VMP) when we have a product market monopolist. When elasticity of substitution, SLK, increase that means the L and K are less substitutable, and the isoquant will be L-shaped. Minimum wage imposed by the government is always bad for the economy because it increase unemployment and deadweight loss. с. d. e. 3.

Three machines are used in a group-technology cell to process a family of five parts. Thetable below lists production quantities (Qj), production times (Tpij), and machine fractionsfor each family member (fij). Part E requires a changeover time of 5 min on each machine soit is produced in batches of 5 parts. Nonoperation times (Tno) are the same for all parts andmachines: 25 min per machine. Determine (a) average hourly production rate for the cell,(b) utilization of each machine and average utilization of the cell, (c) manufacturing leadtime, and (d) work-in-process. A spreadsheet calculator is recommended for this problem

A certain job shop specializes in one-of-a-kind orders dealing with parts of medium-to-high complexity. A typical part is processed sequentially through 10 machines in batch sizes of 1. The shop contains a total of eight conventional machine tools and operates 40 hr/wk of pro duction time. Average time values on each part per machine are: machining time = 0.5 hr, work handling time = 0.3 hr, tool change time = 0.2 hr, setup time = 3 hr, and non operation time = 12 hr. A new programmable machine is being considered that can per form all 10 operations in a single setup. The programming of the machine for this part will require 20 hr; however, the programming can be done off-line, without tying up the machine. Setup time will be just 2 hr because simpler fixtures will be used. Total machining time will be reduced to 80% of its previous value due to advanced tool control algorithms; work han dling time will be the same as for one machine; and total tool change time will be reduced by…
