Optimum Product Mix

Austin Enterprises makes and sells three types of dress shirts. Management is trying to determine the most profitable mix. Sales prices, demand, and use of manufacturing inputs follow:

 

Basic

Classic

 Formal

Sales price  

$30

 $64

 $190

Maximum annual

demand (units) 

20,000

10,000

 30,000

Input requirement per unit

Direct material  

5 yards

.3 yards

.6 yards

Direct labor  

7 hours

2 hours

7 hours

 

Costs Variable costs

Materials

$20 per yard

Direct labor

$16 per hour

Factory overhead

$4 per direct labor-hour

Marketing

10% of sales price

Annual fixed costs

 

Manufacturing

$36,000

Marketing

$8,000

Administration

$30,000

The company faces two limits: (1) the volume of each type of shirt that it can sell (see maximum annual demand) and (2) 30,000 direct labor-hours per year caused by the plant layout.

Required

Show supporting data in good form.

a.How much operating profit could the company earn if it were able to satisfy the annual demand?


b.Which of the three product lines makes the most profitable use of the constrained resource, direct labor?


c.Given the information in the problem so far, what product mix do you recommend?


d.How much operating profit should your recommended product mix generate?


e.Suppose that the company could expand its labor capacity by running an extra shift that could provide up to 10,000 more hours. The direct labor cost would increase from $16 to $19 per hour for all hours of direct labor used. What additional product(s) should Austin manufacture and what additional profit would be expected with the use of the added shift?

Theory of constraints

Every organization faces with some limit or constraint which limits their achievement. Theory of constraints is used to deal with constraint faced by organization. In theory of constraint optimal product mix is chosen which would maximize contribution margin per unit of constraining resource.
