- W227789932 abstract "When planning urban telephone network maintenance and expansion, one has to assign reels of cable to supply all lengths of cable needed. In an ideal world, lengths needed, and the timing of their use, behave exactly as planned. The best solution for buying and using cable reels would then be: match cables exactly to the lengths demanded, and buy them accordingly, use them as needed. In the real world, events may arise which turn desirable to buy cables in standard lengths. The administration of such a case is not at all simple: it involves the assignment of reels from which to cut the necessary lengths, in such a way as to minimize losses. There are some model formulations to represent the problem of supplying lengths needed of some material from standard lengths. Unfortunately, most part of these models are posed from the manufacturer's point of view. That means: as factories do not keep significant finished materials inventory, preferring to produce when needed for supply, those models do not consider carrying costs. In this paper, a model of the problem is presented, that considers both carrying and surplus costs. Some heuristics are proposed to give approximate solutions, and their performances are evaluated." @default.
