Thee we use calculus to find the time interval between training pro- grams that produces the minimum total cost. The model assumes The expression in brackets is the sum of the terms of an arithmetic that the demand for trainees is constant and that the fixed cost ofsequence discussed in most algebra texis Using formulas for arid training a batch of trainees is known. Also, it is assumed that metic sequences, we can show that the expression in brackets is people who are trained, but for whom so job is readily availahle. equal to mom-D/2, so we huve will be psid a fixed amount per month while waiting for a job to mim) The model uses the following variables: D demand for trainees per month; N= nunterofumoes per batch C fixed cost of training a batch of trainees Cvariable cost of training per trainee per month ç³.. salay pand monthly a Iraiere who has not yet as the total cos for keeping jobless trainees The total cost per betch is the sum of the training cost per hatch CmDiC, and the cost of keeping trainces without a proper job, given by equsion (X Since we anvsusme hail: batch of trainees is trained every 'n months, the total cost per mont.
