Abstract: Abstract: The only way to minimize maintenance cost and contemporarily maximize plant availability is to perform a condition based maintenance (CBM) strategy for the main critical equipments of the system. This kind of maintenance requires a condition monitoring system and expert skills in order to forecast the degradation phenomenon. Very often these type of competences and the relative maintenance activities are managed by external service providers. So the actual configuration of the maintenance services of a factory is composed by a network of medium and small enterprise that work coordinating by a main contractor without any real integration or cooperation able to improve service efficiency. In this paper we suggest an approach to achieve a condition based maintenance in legacy plants, without peculiar exceptions for the technology involved, maintained through a collaborative network of enterprises. A demonstration unit was built as a test case for the functioning of the expert system to manage the condition based maintenance and the network of skills involved. In the present work, we present a widening regarding the negotiation mechanism that is one the most important issue of the expert system for the collaborative network management.

Abstract: In recent years there has been great interest in studying stability of switched control systems and their design. This interest is result from wide application of these systems. Many systems perform switching between several subsystems that depends on various environmental factors. A rapidly developing area of switching control is another reason for developing switched systems. Control techniques based on switching between different controllers have been applied extensively in recent years. Some switched systems are similar to the systems with time-varying uncertainties, which we consider as piecewise parameters perturbations. In this paper we consider a MIMO switched plant as a system with parameter perturbations, which change at arbitrary and unknown switching times. Section 2 describes a problem to be studied. Section 3 synthesizes an adaptive controller by the localization principle. It is shown a new approach to synthesis reduces order of the direct adaptive control system. This approach is based on some properties of parameter perturbations. A full order system has a controller with parameters adjustment. If we use the proposed approach, the system will have a controller with an additive adjustment. Section 4 studies the adaptive system stability. All designed systems have a feedback on the state variables derivatives, which leads to two-time scale motions. The proposed closed-loop system is nonlinear, and there are some subsystems with motions having different velocities. Therefore, the study of process convergence is not a simple problem. We study the system stability by the common Lyapunov function and the singular perturbation method. We apply a technique developed for studying stability of a switched systems and the method used for continuous system analysis. In Section 5 numerical examples to demonstrate the effectiveness of the suggested design approach is presented. Section 6 concludes the paper.

Abstract: Robots have played a very important role in the growing popular flexible manufacturing environments. However, state-of-art industrial robots with high accuracy are rather costly and static. Our works aims at providing a low-cost fast integrating platform with advanced middleware support to seamlessly integrate off-the-shelf or future robot sensors, robots, and actuators as well as industrial IT system. To support such approach, a component-based reconfigurable middleware system is designed. A system runtime service is employed to manage the dependence and whole lifecycle of realtime components by reasoning from component’s contract-based service description. A continues deployment mechanism is also designed The software architecture was implemented by so called – Hybrid component model. The evaluation shows that the ARFLEX system achieve the goal of enhance in accuracy, flexibility while provide good real-time characteristics.

Abstract: A new tool for autonomous discrete systems modeling is proposed in this article. It integrates the fuzzy logic in the temporized Petri nets. The uncertainty associated to this activity needs specific reasoning and modeling methods that are different from those of precise reasoning. Fuzzy logic offers the environment for exploiting of the fuzzy parameters and generates more refined results than classical reasoning. In this context, the Recurrent Synchronized Fuzzy Petri Nets (PNetSinFREC) are well adapted to detection/decision modeling of the functions by a temporized fuzzy transition approach in hierarchical systems.

Abstract: We consider a special model of branch planning, where the final product obeys a preset assortment relation. The ratio coefficient is maximized. Constraints are given in the form of linear inequalities with block diagonal structure of the part of a matrix that corresponds to subsystems. The central coordinator assembles the final production from the components produced by the subsystems. Therefore, the binding constraints of the initial matrix are specific: their submatrices are diagonal. This structure suggests a special decomposition algorithm, where variables from various blocks are aggregated. Here, all the difficulties related to the large number of dimensions, i.e., the large amount of subsystems and components they produce, are reduced to a simple aggregated problem of the upper level, which consists in finding the minimal element of a large-dimension matrix.

Abstract: This paper presents a set of algorithms developed for real-time dynamic switching between collaboration levels in a human-robot target recognition system. The algorithms were developed for a closed-loop controller to maximize system performance despite deviations in the parameter values and were evaluated by conducting a thorough simulation analysis. These developments enable smooth real-time adaptation of the combined human-robot system to many possible changes of the environment, human operator and robot performance. System performance was analyzed in simulations for a variety of target probabilities distributions. Improvements that can be achieved by each algorithm were calculated as a mean value for 200 independent simulations for each target probability distribution. The numerical analysis results indicated that the developed algorithms for dynamic switching achieved improved system performance.

Abstract: In this paper, we consider the problem of creating synthesized programs to implement a controller automatically generated through discrete-event control synthesis techniques. The controller is represented as a set of discrete event models comparable to extended state machines, where the individual control components interact with each other and with the plant via condition signals. We discuss three alternative approaches for the synthesized program to represent these control components. We discuss benefits and drawbacks to each.

Abstract: This article presents a multi-agent based algorithm for personnel scheduling and rescheduling in the dynamic environment of a paced multi-product assembly center. Our purpose is, on the one hand, to elaborate daily assignment of employees to workstations to minimize the operational costs as well as the personnel dissatisfactions and, on the other hand, to generate an alternative planning when the first solution has to be rescheduled due to disturbances related to operators' absenteeism. The proposed approach considers the individual competencies, mobility and preferences of each employee, as well as the personnel and competency requirements associated with each assembly activity given both the current master assembly schedule and the line balancing for each product. To benchmark the performance of the multi-agent approach, we use solutions obtained through a simulated annealing algorithm. Experimental results show that our multi-agent approach can produce high-quality and efficient solutions in a short computational time.

Abstract: Maintenance has been experiencing a slow but constant evolution across the years, from the former concept of "badly necessary" up to being considered as a vital function within a company and a strategic leverage for gaining a sustainable competitive advantage. In this context, it is necessary to consider maintenance as a set of managerial activities whose objectives and related decisions need to be consistent. The paper provides an insight on the main decision categories, traditionally conceived for the manufacturing management context, which are relevant for a maintenance system. A model, based on Analytic Hierarchy Process, has been developed and tested in two industrial case studies in order to understand which are the decision categories that can exert a major impact on the maintenance strategies of a company.

Abstract: Contrary to many academic problems which consider distribution only, some vehicle routing problems which must be solved by transporters combine deliveries and pickups. The literature on such problems is still scarce, in spite of their realism. An important example is the Vehicle Routing Problem with Mixed linehauls and Backhauls (VRPMB), in which some goods must be delivered from a depot to linehaul customers, while others must be picked up at backhaul customers to be brought to the same depot. This paper studies an enriched version called Heterogeneous fleet VRPMB with Time Windows or HVRPMBTW. An integer linear programming formulation and an Ant Colony Optimization algorithm (ACO) are proposed. The ACO is compared to a multi-start savings heuristic inspired by the one designed by Rieck et al. (2007) for a different problem with backhauls and better results are reported.

Abstract: Frame contracts are widely used to determine quantities and prices in customer-supplier relationships for long-time horizons. Additionally quota agreements can be defined which regulate the delivery share for a certain product between two or more suppliers. This paper describes an approach to reach good quantity allocations in single time periods by regarding supplier rebates and special offers and at the same time maintaining the contract restrictions in the frame contract horizon. As basis a framework is introduced that defines flexibility contracts and coordination rules between the participants.

Abstract: To be attractive, a self-service public transportation (bicycles or cars) must ensure to the subscribers a degree of availability without fault. The management of the technical and human means remains all the more difficult as it is about a dynamic system, with seasonal tendency, and strong behavioral coloring. This work proposes a hybrid method by coupling concepts of fuzzy logic, process optimization and utility theory in order to model the preferences of the subscribers and to determine the use rate of the stations. The manager of a car-sharing service can use it in order to ameliorate performance indicators such as the availability of the cars and the balance of the stations.

Abstract: This paper deals with a transfer line balancing problem. It is a generalization of the well-known assembly line balancing problem. In transfer line balancing the operations to be executed are partitioned into blocks. The operations of each blocks are carried out simultaneously by a single piece of equipment. The blocks assigned to a workstation are executed in series. The aim is to design the line having the minimal weighted sum of workstation and block numbers while the precedence and cycle time constraints are respected as well as additional constraints. The approach proposed in this paper is based on the reduction of the considered balancing problem to a special set partitioning problem.

Abstract: In automatized industrial systems, inactivity due to unplanned resource shortage or processes failures have a great influence on the system’s performance because it generates discontinuities and instabilities. Distributed and autonomous control systems may help to cope with these kinds of problems because of the higher performance, but safety issues and real time constraints must be tightly addressed in these systems because of the risks involved (human, financial and environmental). Thus, an intelligent control system instantiated at the local level to allow each controller to take critical decisions in an autonomous way is proposed here. Above that, a supervisory system manages more complex situations beyond the capabilities of local control. The proposed control aims to enable auto-adjustment in the system to improve performance and to prevent and treat unexpected faults. It therefore has to learn through events which have occurred in the system and environment using Artificial Intelligence tools.

Abstract: Duncan is the pioneer to provide a control chart design from economic-view point in 1956 and ensure that the economic design of control charts is really lower the cost compared with a conventional Shewhart charts. An economic design does not consider the statistics properties, such as type I or type II error and average time to signal (ATS). In order to improve these issues, an economic-statistical design of control charts was proposed under the statistical consideration. Usually, a product is accepted if the product measurements meet specification requirements and there are no quality losses in the most of economic or economic-statistics design of control charts. Taguchi’s Quadratic loss function was employed in this research to construct the quality losses for economic-statistical design of x-bar control charts with multiple assignable causes. A numerical example is also used to illustrate its working of the proposed model and to compare the lost cost among the pure economic, economic-statistical control charts design and economic-statistical control charts design using Taguchi’s loss function. The example shows that the social loss from the Taguchi’s Quadratic loss function is the most important cost compared with the original cost items.

Abstract: In this paper, we present an accurate and fast algorithm for maximizing profits through buffer size optimization for production lines. We consider both buffer space cost and average inventory cost with distinct cost coefficients for different buffers, and we include a nonlinear production rate constraint. To solve the problem, a corresponding unconstrained problem is introduced and a nonlinear programming approach is adopted. Numerical results are provided to show the efficiency and accuracy of our algorithm for both short and long lines.

Abstract: Group sequencing is a well-studied scheduling method for the job shop problem. The goal of this method is to have a sequential flexibility during the execution of the schedule and to guarantee a minimal quality corresponding to the worst case. But the best case quality of a group sequence should also be interesting. This article presents a new method to evaluate the best-case quality. This method is a branch and bound algorithm to find the optimal solution for any regular objective. Experiments show the efficiency and the limits of the exact method.

Abstract: In this paper a generic method for fault detection and isolation (FDI) in manufacturing systems considered as discrete event systems (DES) is presented. The method uses an identified model of the controlled process to be monitored which is built on the basis of observed fault free behavior. A special term of accuracy is motivated that helps to identify an efficient model. This paper gives an overview of the method that consists of the identification and the use of the identified model for fault detection and isolation. Furthermore, the theoretical framework of the method will be explained. Experiences of an industrial application are described to show the relevance of the method for large scale manufacturing systems in operation.

Abstract: We present in this paper a problem combining two planning problems studied in the literature: the problem of capacitated lot sizing with shortage cost and the problem of determining optimal maintenance cycle. The aim of our study is to build a new model of joint planning of production and maintenance where preventive maintenance times are carried out in time windows to better meet customer demand. We provide an illustrative example that show the effectiveness of integrated model if we compare it to separate model.

Abstract: We analyze the component testing problem of devices which consist of series connection of redundant, standby redundant and k-out-of-n subsystems. Although system reliability is a common performance measure, here we extend previous studies by considering expected system lifetime. This case applies when setting mission time for a system is more practical than deciding on system reliability accurately. The problem is formulated as a semi-infinite linear programming problem, and the optimum test times are obtained with a column generation technique incorporating reverse convex programming. The proposed solution technique is also illustrated by numerical examples.

Abstract: A two-stage mathematic programming model is established in this paper for the integrated production planning and scheduling problem in bell-type anneal shop. The stage I aims at the minimized heating time of each base to optimize the furnace-charging combination. The stage II based on the combined anneal plan is to obtain an optimized resource scheduling solution in order to minimize the resource free ratio. In this stage, a discrete event simulation technology based on SystemC platform and an adaptive genetic algorithm are used. Finally, the simulation experiments using practical production data show the proposed two-stage integrated method is effective and reliable.
