This paper attempts to solve a comprehensive design problem for a spare part logistic system. The design factors encompass logistic network design, part vendor selection, and transportation modes selection. Two approaches to solve the problem were proposed. In Approach 1, we simultaneously considered all the design factors and proposed two algorithms (SGA-1 and TGA-1). In Approach 2, the design...

In this report, the researchers depict how an objective measure, the Participation Assessment with Recombined Tools-Objective (PART-O), was developed and tested for survivors of traumatic brain injury (TBI). The PART-O was created through utilizing a pool of items from the Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF), Community Integration Questionnaire version 2 (CIQ...

Design for maintenance and maintenance operations become increasingly important in recent years. In the capital-intensive industry, maintenance expenditures can add up to several times the initial investment. In order to be competitive in their business, owners and users of these capital goods have to take into account the total life cycle cost at investment (the lifespan of a train is about 30...

Purpose – For more than ten years, the value of additive manufacturing (AM) for after-sales service logistics has been propagated. Today, however, only few applications are observed in practice. In this paper, possible reasons for this discrepancy are discussed and a method is developed to simplify the identification of economically valuable and technologically feasible business cases. Design/m...

303  Abstract— Inventory management is the process of efficiently overseeing the constant flow of units into and out of an existing inventory. Inventory management of spare parts plays an important role in achieving the desired plant availability at an optimum cost. This paper presents a spare part classification method based on item movement in store department and criticality. FSN analysis i...

1 Shu Jin Lee, MD Kathleen Ong Department of Surgery National University Health System Singapore Sir: W describe an unusual case of multiple trauma in which the patient fell from a height of 20 m, sustaining panfacial fractures with severe nasoethmoid fractures and soft tissue concertina of the entire bony cartilaginous complex of the nose together with an open fracture of the right humerus com...

“Spare parts surgery” is well-described in the plastic surgery literature. In the setting of trauma, otherwise discarded parts can be utilized for reconstruction resulting in a superior functional and aesthetic outcome for the patient. We describe the use of spare part surgery in order to preserve a functional knee articulation in a patient undergoing amputation for compartment.

The telecommunication industry depends on unit level mobility to respond to unexpected demands occurring over a large geographical range. If the response is not timely and comprehensive, these units may fail to meet the customer' required. Therefore, many telecom enterprises prepared abundant spare part. The arrangement provides "timely and wonderful" service while they raise the debt-to-asset ...

The technician routing and scheduling problem consists in routing and scheduling a crew of technicians in order to attend a set of service requests, subject to skill, tool, and spare part constraints. In this study we propose a formal definition of the problem and present a constructive heuristic and a large neighborhood search optimization algorithm.

Two variants of a simple stochastic model for planning the inventory of spare components supporting maintenance of an industrial system are developed. In both variants, the aim is to determine how many spare components are needed at the beginning of a planning interval to fulfil demand for corrective replacements during this interval. Under the first variant, the acceptable probability of spare...
