Storage and distribution of the finished products are the primary logistics activities, and particular attention will be paid to them in this text.

These choices are made by the company according to the same logic on which ‘make or buy’-type decisions are based. They assume an in-depth knowledge of the nature of the costs that the company bears (fixed costs, variable costs, direct costs, and indirect costs).
