The article describes the ways of industrial development in era transition from a linear model economy to circular model, as well new trends logistics. It shows interconnection processes production systems, logistics and services, their role ensuring sustainable green growth. is shown that by closing loop product lifecycles, reverse plays an important transitioning economy. presents example pla...

Field services are a particular type of after-sales service performed at the customer’s location where technicians repair malfunctioning machines. The inventory decisions about which spare part types to take to the repair site and in what quantities is called the repair kit problem. This problem is characterized by an order-based performance measure since a customer is only satisfied when all r...

In this paper we present an area-efficient register transfer level technique for gracefully degradable data path synthesis called phantom redundancy. In contrast to spare-based approaches, phantom redundancy is a recovery technique that does not use any standby spares. Phantom redundancy uses extra interconnect to make the resulting data path reconfigurable in the presence of any (single) funct...

in this paper a new problem of three stage disassembly-assembly scheduling is introduced and reviewed. this problem, which was arisen from the aviation industry characteristics, is a generalization of the two stage assembly scheduling problem. products (helicopters) in the aviation industry return to assembler for annual overhaul repair services. in the first stage helicopters are disassembled ...

The description of the road and natural-climatic conditions for operation timber-carrying trains is given. main features logging roads, which are characterized by insufficient infrastructure, considered. analysis negative consequences movement along such roads in various natural climatic carried out. dependences change speed fuel consumption a train on nature longitudinal profile road, performa...

This paper investigates the gap between research and practice in spare parts management, with specific reference to durable goods addressed to private or professional customers. The paper provides a critical literature review of theoretical contributions about spare parts classification and demand forecasting for stock control. The discussion of ten case studies, then, allows to analyze the rea...

Physicists love emergence. From a welter of complex details about a system's constituents, simple and universal rules sometimes emerge that adequately describe the collective behavior of the components. Even if these rules are not completely universal, they often have only a few relevant parameters, a vast simplification compared to the many that describe the constituents individually. But as V...

In this paper, we present a strongly fault-tolerant design for the k-ary n-cube multiprocessor and examine its reconfigurability. Our design augments the k-ary n-cube with ðjÞ n spare nodes. Each set of j regular nodes is connected to a spare node and the spare nodes are interconnected as either a ðkjÞ-ary n-cube if j 61⁄4 k2 or a hypercube of dimension n if j 1⁄4 k2 . Our approach utilizes the...

After sales service is a major source of competitive advantage for the firms in current business environment. The quality of the service depends on a number of factors among which availability of spare parts at the service centers is the most critical. It is very difficult to maintain the desired inventory of spare parts due to the increasing product complexity and variety. The variation in dem...
