While forecasting has received considerable attention in the manufacturing and marketing literature, there has been little research on forecasting in services especially in the context of service arrivals in a repair or refurbishment center. In this paper, we propose several methods for forecasting service arrivals in a repair center. A preliminary evaluation of the alternative methods is also provided.

The models for multi-echelon inventory systems in existing literatures predominantly address failures due to reliability in peacetime. In wartime or even peacetime operational scenarios, unexpected combat damage can cause a large number of systems to be heavily damaged, to the extent that they become irreparable. In this paper, we study a multi-echelon spare parts support system under combat damage, discuss the replenishment policy and propose an approximate method to evaluate the time-varying system performance operational availability considering the effect of passivation. Experiments show our model works well and efficiently against simulation.

An architecture for control of flexible production systems is presented, with focus on flexibility, generality, and reusability. The architecture is based on a framework which partitions the control system into the following main components: resources, product routes, control functions, the operator's interaction and the information system. The clear separation of the resources employed from the products' paths through the plant is important in order to simplify the handling of changes to the system, for instance when introducing new equipment or new product types. Compared to an earlier preliminary result [Lennartson, B, et al., Oct. 2002] this paper introduces a new formalism based on process algebra. It means that high level user friendly but still formal specifications are achieved for resources as well as product routes. Both event and state based specifications are illustrated related to industrial applications.
提出了一种柔性生产系统控制体系结构,重点关注灵活性、通用性和可重用性。该体系结构基于一个框架,该框架将控制系统划分为以下主要组件:资源、产品路线、控制功能、操作员交互和信息系统。为了简化系统变更的处理,例如在引入新设备或新产品类型时,将所使用的资源与产品通过工厂的路径明确分离是很重要的。与早期的初步结果[Lennartson, B, et al., october 2002]相比,本文引入了一种基于过程代数的新形式主义。这意味着对资源和产品路线实现了高层次的用户友好但仍然正式的规范。基于事件和状态的规范都与工业应用相关。

In this paper we present an algorithm for planning the path of a 3 DOF mobile platform for a humanoid robot. It is simple enough to be executed online and yet powerful enough to generate a smooth path from starting point and orientation to a destination point with a different orientation. Thus we strive to achieve a human-like appearance of our robot that encourages the humans in vicinity to interact with our humanoid robot and enhances the possibilities of human-robot collaboration. We opted to use NURBS curves as the basis for our path planning algorithm

A novel single-axis flexure hinge named right-circular corner-filleted (RCCF) flexure hinge, which is composed of half a right circular one and half a corner-filleted one, is presented. The flexibility expression, maximum stress and rotation precision of RCCF flexure hinge is provided, and validated by finite element method. Take the micro-adjustment mechanism in double-crystal monochromator for example; a group of RCCF flexure hinges with different corner-filleted radii are analyzed using the ANSYS finite element software, including a special RCCF hinge, i.e. right-circular hinge. The results show that the RCCF flexure hinges are more compliant than right-circular hinge and as precise as it in rotation. The RCCF flexure hinge is suitable for engineering applications where high displacement and high accuracy are needed.

Recently, independent third party logistics providers who perform all or part of the firm's product distribution function allow many manufacturers to focus on its core competencies rather than on the distribution expertise. In this situation, collaboration between a manufacturer and a third party logistics provider is indispensable for successful production-distribution coordination. However, while information must be shared between them for coordination purpose, they hope to communicate with each other using minimum proprietary information regarding their own business. For efficient coordination of this type of supply chain, a new decentralized coordinating model based on minimum information sharing is proposed. This decentralized coordinating model is implemented on a multi-agent system. The preliminary result with a numerical example shows a very promising performance of the proposed model, when compared with that of an ideal centralized model.

Ladder logic diagram (LLD) as the interfacing programming language of programmable logic controllers (PLCs) is utilized in modern discrete event control systems. However, LLD is hard to debug and maintain in practice. This is due to many factors such as non-structured nature of LLD, the LLD programmers' background, and the huge sizes of real world LLD. In this paper, we introduce a recurrent neural network (RNN) based technique for PLC program diagnosis. A manufacturing control system example has been presented to illustrate the applicability of the proposed algorithm. This method could be very advantageous in reducing the complexity in PLC control programs diagnosis because of the ease of use of the RNN compared to debugging the LLD code.

Wireless communication technology has been increasingly adopted in various business environments of supply chains. Radio frequency identification technology provides real-time information of vehicle movements and, associated shipment operations can benefit from it for better, efficient load makeup. A Markov decision process model is proposed for dynamically building the shipment loads using real-time information of the wireless tracking system. Simulation results demonstrate the superior performance of dynamic decision approach compared to conventional shipment practices in terms of reducing vehicle dwell time, improving customer fulfillment, and increasing utilization of the transportation carriers.

This paper generalizes the use of the hybrid timed Petri net method introduced in [Tsinarakis, G. J. and Valavanis, K. P., 2004] to study multi-operational production systems in which incoming or in-process parts are used for different products production. In particular, the proposed multi-assembly machine module is generalized to describe a machine performing multiple assemblies consisting of different initial parts numbers. The applicability of the method is illustrated through an analytical example.

A capillary-based fluid handling system, the ACAPELLA-5K (ASK), has been developed to prepare precise mixtures of sample and reagents in glass capillaries at a rate of 5000 preparations in 8 hours. Following a user-defined protocol the system architecture enables sample aspiration, reagent dispensing, mixing, and thermal cycling, with intermediate imaging steps for in-process monitoring of critical fluid delivery steps. A serial pipeline process is used to provide flexibility, reproducibility, and reliability for the reactions prepared. A typical reaction comprises a 0.5 /spl mu/L sample aspirated from a microplate well followed by 1 to 8 reagents dispensed in 40-100 pL droplet volumes using piezoelectric reagent dispensers. Reactions are then mixed to prepare a 2.0 /spl mu/L final reaction volume. Reaction volumes from 0.5-2 /spl mu/L have been demonstrated, representing performance comparable to the state-of-the-art in a majority of core sequencing facilities. A5K has been extensively tested in the preparation of deoxyribonucleic acid (DNA) polymerase chain reaction (PCR) and DNA sequencing reactions. Other applications of the A5K platform of technologies include quantitation of minimal residual disease, protein crystallography, and potential for application in drug discovery, forensics, and DNA analysis of environmental samples.
