Since the T.C. curve is fairly flat in the region of minimum cost, the total variable cost is not terribly sensitive to deviations from optimal batch size. It is possible, therefore to adopt a batch size which differs slightly from the optimal without incurring substantially increased costs. Batch quantities within this production range are considered as acceptable.
Tangu T.C. Curve ni haki gorofa katika mkoa wa gharama za chini, jumla ya gharama variable ni si sana nyeti kwa deviations kutoka mojawapo ukubwa wa kundi. Inawezekana, kwa hiyo kupitisha kundi ukubwa ambayo hutofautiana kidogo kutoka mojawapo bila incurring kikubwa kuongezeka gharama. kiasi kundi ndani mbalimbali huu uzalishaji ni kuchukuliwa kama kukubalika.
