The demand for Piston Cup Forging in spare-part companies every period has increased and decreased, which causes uncertainty about product demand. In this case, the company needs to do forecasting. There are various methods of doing Companies must choose best forecasting method, so that can make decisions more effectively efficiently. This research aims compare apply companies. will be compared...

We consider an integrated-services communication network handling, in particular, best-effort data traffic and rate-regulated, delaysensitive variable bit-rate (VBR) traffic. From the user’s perspective, the pricing mechanism of the network may provide an incentive for the user to transmit best-effort packets in the real-time VBR channel, i.e., transmit best-effort packets “in-band” using some ...

In error prone environments not all the picture data can be received correctly during video transmission. Error propagation introduced by employing predictive coding may degrade the sequence quality severely. A novel method, called spare pictures, is proposed to indicate the similarity between a reference picture and other pictures. With the help of the signaled spare pictures information, rece...

This article presents theoretical basis of spare parts inventory management in manufacturing company. Basis definitions, allocation and differences in spare parts inventory management were compared with other manufacturing inventories. The issue of spare parts inventory management is emphasized in aspect of maintaining continuity of production and generated costs of maintaining inventory.

In this paper, a new model has been presented to determine the number of spare transformers and their locations for distribution stations. The number of spare transformers must be so that they need minimum investment. Furthermore, they must be sufficient for replacing with transformers that have been damaged. For this reason, in this paper a new purpose function has been presented to maximize p...

Original Equipment Manufacturers (OEM’s) of advanced capital goods often offer service contracts for system support to their customers, for which spare parts are needed. Due to technological changes, suppliers of spare parts may stop production at some point in time. As a reaction to that decision, an OEM may place a so-called Last Time Buy (LTB) order to cover demand for spare parts during the...

In this paper, we present a strongly faulttolerant design for the l-level k-ary tree multiprocessor and examine its reconfigurability. Our design assigns one spare node to the regular nodes of each subtree with lc levels. Moreover, spare nodes are interconnected to form a spare tree. Our approach utilizes the circuit-switched capabilities of the communication modules of the spare nodes to toler...
