概要	Weber's industrial location model is the classic least-cost theory of where a manufacturing plant should locate. Developed by Alfred Weber in 1909, it finds the site that minimizes total transport cost between the sources of raw materials and the market, then adjusts that site for savings in labour cost and for the benefits of clustering with other firms. The transport optimum is found at the Weber point of the location triangle, where the pulls of material sources and the market balance — the foundational model of industrial geography.	Central place analysis is the study of the size, number, and spacing of settlements as service centres, grounded in Walter Christaller's central place theory of 1933. It explains why settlements form an orderly hierarchy — many small villages, fewer towns, a handful of cities — and why higher-order centres are spaced farther apart and offer more specialized goods, deriving the famous nested pattern of hexagonal market areas from two economic concepts: the range and the threshold of a good.
