This research investigates a k-out-of-n system in which the lifetime of operational and standby components, the repair time follow continuous phase-type (PH) distribution, instead of exponential distribution or others typical distributions. The proposed paper provides an analytic reliability model that is more suitable to characterize the real situation. The stationary distribution is built by using matrix analytic methods; and several reliability measures of interest are obtained, such as the system stationary availability, system up period, mean time between failures (MTBF) and mean number of failures per unit time (MNF). Finally, a numerical example is presented which implements the applicability and calculability of the model and demonstrate how system reliability measures are influenced by parameter k when n is fixed.

This paper aims to develop a parameter estimation approach for load-sharing systems subject to continuous degradation. The system consists of multiple components in parallel structure. The components of the system suffer a degradation process, characterized respectively by Wiener process and Inverse Gaussian process. When components fail one by one, the total workload is redistributed among the remaining components, which accelerates the degradation process of the surviving components, which is referred to as a load-sharing system. Maximum likelihood estimation (MLE) is used to estimate the parameters for a load-sharing system. The available data are the failure times of the components and the degradation level of the remaining components at failure time. For Wiener process, a close-form MLE is derived and an analytical solution is achieved. For inverse Gaussian process, however, it is difficult to obtain a close-form MLE and numerical method is adopted instead. Finally, numerical studies are conducted to illustrate the estimation procedure.

This paper presents a low cost system for human gait analysis. Two opposite-faced web cameras are used to acquire images of the walking of a person carrying a set of passive marks, where the color is chosen to contrast with the ambient dominant color. It is also used a treadmill with passive marks, where the user walks at different speeds. The acquired trajectories of the marks are used to determine body joint angles and other 3D crossed angles, obtained by both opposite sides from video images processing. With this low cost measurement system the analysis and reconstruction of human gait can be done with a mean error of 2 degrees, becoming a good alternative to more expensive systems to be used in human gait characterization. The system can be used to detect human gait pathologies and to accomplish physical rehabilitation.

A two dimensional maintenance contracts with coordcination between two parties is studied in this paper. The contract is applied to a dump truck operated in a mining industry. The situation under study is that an agent offers two dimensional service contract to the owner of the truck. The owner's decision to get high availability and the agent's decision to minimize the total maintenance cost are coordinated in order to reach a win-win solution. In addition, we consider the use of incentive contracts to the agent based on a combination of a target uptime level and a bonus. This is done in order to obtain a win-win situation and provides flexibility in allocating the extra profit generated from coordination.

Production of engineering drawings have evolved from manual to Computer Aided Design (CAD), primarily for the speed and accuracy presented by CAD. Unlike modelling and simulation packages that are equipped with building blocks, CAD packages are generally supplied with no pre-drawn symbols. From best practices in industrial engineering and working for companies that make use of CAD systems, evidently a lot of time is spent in repetitive tasks in the development of engineering drawings. An industrial engineering approach was adopted in this research where programming was used as a separate process from any specific application to an organization through the creation of a catalogue of almost 500 commonly used engineering symbols and storing them in a database, coupled with an add-on facility for AutoCAD for easy retrieval, aimed at avoiding these repetitive tasks, hence facilitating the rapid production of drawings to improve productivity and efficiency when using CAD systems.

The modularization strategy can dramatically shorten the lead time and reduce the cost of complex products development, and module partition is the basis of the modularization. In this paper, a complex network module is built to represent the complex product structure, and using interval-valued intuitionistic fuzzy sets to calculate the weights of the edges of the network model are brought to illustrate the correlation strengths among parts. Based on this, Software UCINET is given for product module partition. Moreover, the example results illustrate that the network model and UCINET performs.

We study a repairable service parts inventory system with a central repair facility and several inventory holding locations. In case of a part failure, the failed part is identified and replaced with a ready-to-use part. Afterwards, the failed part is sent to the repair facility, where it is repaired and allocated to one of the bases. The objective is to identify the base with the most urgent need of a service part in order to minimize the expected backorder cost. To this aim, we investigate the initial base-stock provisioning problem in conjunction with the real time stock allocation decision making. We propose a heuristic technique for stock allocation based on relative value function and average backorder cost. We compare the performance of the heuristic model against the myopic policy to validate the efficiency of our proposed mechanism. Results reveal that the proposed stock allocation policy outperforms the myopic policy.

As battery electric vehicles are more and more popular nowadays, this paper presents an Electric Vehicle Routing Problem with Time Windows and Battery Swapping Stations to extend their range of application. In the problem, a fleet of the same kind of battery electric vehicles will fulfill the demand of all customers within the serving area by means of delivery operation with a fixed battery swapping time. Time windows of customers are taken into consideration. Small instances of benchmark problem are extended and testified by Gurobi optimizer. Two models of swapping and recharging pattern are compared with the same parameters, verifying that the swapping mode can decrease the number of vehicles.

Market trends of the last two decades showed a high demand for customer innovated products. The production of individualized batch-size-one products requires a production planning and control (PPC) paradigm shift. This paper therefore provides an insight into requirements for PPC of customer innovated products. Customer-specific order processing, an approach to time and capacity planning as well as an adaptation of flexible-batch-size production are furthermore explained. At the end, a prototypical industrial implementation based on a household appliance manufacturing company is illustrated.
