Lean Production and Agile Manufacturing are currently two popular methods of production. These two popular methods are based on different levels of supply chain optimization and there is an integrated space between these two popular methods. In this paper, we analyse the lean and agile production coupling point or Decoupling Point (DP) in two types of supply chain integration model based on some parts' or components production process, under the constraints of time, cost and other factors in the supply chain operation and production process. Finally we carry on critical path analysis on the selection of the lean and agile production coupling point or Decoupling Point (DP), and then achieve the optimal integrated strategy.

As global warming becomes more prevalent and resource scarcity and oil prices continue to rise, a green business strategy has become of greater importance and necessity. Societies and governments have become more sensitive about issues regarding the environment. That is why companies need to react on the challenges of green issues by implementing sustainable or green supply chain management (GSCM). To focus on their competences, a lot of companies outsource their logistics activities to third-party logistics providers. Hence, on the way to green supply chain, not only the companies as outsourcers have impacts, but also the logistics service providers. The main aim of this paper is to identify the different decision making modes towards green supply chain.

The extensive use of Poka-Yoke (Mistake-proofing) devices enables Jidoka (machines with human intelligence) as one of the two pillars of Toyota Production System (TPS). Despite the worldwide adoption of Lean/TPS and the key contribution of Poka-Yoke to the Japanese quality miracle, Poka-Yoke has been largely ignored in academia. This paper narrows the research gap by introducing Information System Design (ISD) as a new way of design for Poka-Yoke and illustrating how wireless communication technologies increase the capacity of ISD Poka-Yoke. A case study is conducted in the paper to explain how wireless devices enabled ISD eliminate three types of human errors in a manufacturing logistics process. In general, ISD Poks-Yoke overcomes the limitation of traditional Engineering Design (ED) Poka-Yoke, by extending the applicability of Poka-Yoke concept to non-production processes. With the integration of wireless devices, ISD can even be used to mistake-proof logistics processes which are often mobile in nature.

In aiming for behavioral fidelity, artificial intelligence cannot and no longer ignores the formalization of human affect. Affect modeling plays a vital role in faithfully simulating human emotion and in emotionally-evocative technology that aims at being real. This paper offers a short expose about three models concerning the generation and regulation of affect: CoMERG, EMA and I-PEFiC(ADM), which each in their own right are successfully applied in the agent and robot domain. We argue that the three models partly overlap and where distinct, they complement one another. We provide an analysis of the theoretical concepts, and provide a blueprint of an integration, which should result in a more precise representation of affect simulation in virtual humans.

Today factories can be considered as products, which contribute to value creation by efficient transformation of resources into high-adding value products and which have to be continuously adapted. The engineering of future factories requires digital tools to support the life cycle phases from investment planning to ramp-up and scientific-based integrated highly-dynamic data management systems. This paper presents a Reference Model for holistic Factory Engineering and Design and a Grid-based Factory Data Management, centred on a generic Factory Data Model based on state-of-the-art Grid, workflow and digital manufacturing technologies. The developed planning environ-ment, its architecture, the employed technologies, the estimated benefits and a validation scenario are presented and integrated in a Roadmap of current and future research activities in the field of factory engineering and design.

Tourism industry is supported by the network of organizations and people in the travel industry. Some tourism networks, such as tourism distribution channels and tourism supply chain (TSC), have been explored by some researchers in recent years. The inter-organizational relationships have also received a lot of attention from researchers in tourism area. However, most studies focus on adversarial relationships due to the intensive competitions among the service providers. Many studies on coordination strategies in the manufacturing supply chains have shown that it can result in improved performance and greater profitability for the entire supply chain and participants. It is believed that applying supply chain coordination strategy to the tourism industry provides a new research opportunity to generate insights into how a TSC develops a sustainable competitive advantage, especially when the demand uncertainty is high. Along this line, this paper studies a vertical coordination relationship in a tourism supply chain consisting of tour operators and their accommodation supplier. In regular intervals, tour operators and their supplier sign contracts on the volume that the supplier will allocate to them for the coming season. In the vertical coordination scheme based on return policies, the supplier buys back the unused reservations from tour operators at the end of the season. Game models are used to analyze and establish the coordination relationship. To the best of our knowledge, little in-depth analytical research on coordination strategies adopted in the tourism industry has been carried out, and there has been a particular lack of analysis using game-theoretic approaches.

This paper presents a cooperative framework for dynamic spectrum access in cognitive radio networks, where the cognitive radio devices may use the currently unutilized spectrum dynamically and opportunistically. The proposed solution works on the principle of multiagent system that allows the cooperation amongst several participating devices. The key aspect of our design is the deployment of agents on each of the primary and cognitive radio device that cooperates in order to have a better and dynamic use of the spectrum. For cooperation, contract net protocol is considered allowing spectrum to be dynamically allocated by having a series of exchange of messages. Due to the concurrent, distributed and autonomous nature of our approach, Petri nets are adopted to model the behavior of cooperative framework. Based on Petri nets, we study the internal message passing and spectrum allocation mechanism between the participating primary and cognitive radio users and identify the information needed by the agents to make cooperative decisions. Then, using empirical results, we show that our approach achieves up to 80% of the whole utility within the span of few messages, and provides an effective mechanism for distributed spectrum allocation.

The Fabrication of aircraft structural parts is the bottleneck for manufacturing the modern aircrafts due to their structure complexity and technical difficulty. In order to improve the capability to fabricate the complicated aircraft structural parts and the efficiency of technical preparation, and also to accumulate and share the domain knowledge of manufacturing process, and reuse the 3D product model in the procedure of manufacturing, this paper introduced a kind of 3D-model-based integrated CAPP system by using digital and intelligent manufacturing technology, with which some problems above can be solved when manufacturing aircraft structural part. Some key technologies related to 3DCAPP system, such as the modelling technology of 3D manufacturing feature, the feature-based typical processing template, the procedure of knowledge-based process decision-making and visual manufacturing process on-machine application and so on, are introduced in this paper in details.

A musculoskeletal disorder is a condition of the musculoskeletal system which consists in that part of it is injured continuously over time. Shoulder disorders are one of the most common musculoskeletal cases attended in primary health care services. Shoulder disorders cause pain and limit the ability to perform many routine activities and affect about 15-25% of the general population. Several clinical tests have been described to aid diagnosis of shoulder disorders. However, the current literature acknowledges a lack of concordance in clinical assessment, even among musculoskeletal specialists. In this work a Computer-Aided Decision Support (CADS) system for Shoulder Pain Pathology has been developed. The paper presents the medical method and the development of the database and the (CADS) system based on several classical classification paradigms improve by covariance estimation methods. Finally the system was evaluated by a medical specialist.

The study of development processes is a key issue regarding quality of final products and reutilization of process portions or fragments. In this work, the process of a particular methodology for Agent Oriented Development is defined using a standard notation, in particular SPEM 2.0. This case study shows the suitability of process definition as a starting point for reuse of the development process in the Agent Oriented software Engineering field. Moreover, the results obtained will permit to design a customizable CASE tool that can fit in any development process previously defined.
