Three o r models have additional features, also each has demand which is normally distributed, with a mean of 1,000 also a standard deviation of 700. Presently all four models are manufactured on same line at a cost of $100 for Peter also $110 for each of other three models. Peter sells for $200, whereas each of o r three models sells for $220. Any unsold blowers are sold at end of season for $80. Robert is considering use of tailored sourcing by setting up two separate lines, one for Peter also one for  other three.

Production cost of o r three products, elucidate however, will now increase to $120. Do you recommend tailored sourcing for Robert?
